We can send data between two individual applications in Android if the receiving application is configured to received that type of data.
For example if an application is to receive Image data then it’s manifest should contain the ImageFilter as Shown below

 <intent-filter>
                <action android:name="android.intent.action.SEND" />

                <category android:name="android.intent.category.DEFAULT" />

                <data android:mimeType="image/*" />
            </intent-filter>

For example ac activity in the receiving application is named “Receiver” then its entry in the AndroidManifest.xml should be like this.

 <activity
            android:name="com.example.receivingapplication.Receiver"
            android:label="@string/app_name" >             
            <intent-filter>
                <action android:name="android.intent.action.SEND" />

                <category android:name="android.intent.category.DEFAULT" />

                <data android:mimeType="image/*" />
            </intent-filter>
        </activity>

This line means that the Receiver application can receive any image type data.

Now in this post I have two application each have an activity. One is the Sending application and other is the receiving application.

At first I will explain what am I doing in “Sender application”

SENDING APPLICATION STARTS

My Only activity in the SenderApplication will have a layout like this

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context=".MainActivity" >

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignRight="@+id/textView1"
        android:layout_below="@+id/textView1"
        android:text="Send Text" />

    <Button
        android:id="@+id/button2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignRight="@+id/textView1"
        android:layout_below="@+id/textView1"
        android:text="Send Image" />

    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_above="@+id/textView1"
        android:layout_alignLeft="@+id/button1"
        android:layout_marginBottom="68dp"
        android:src="@drawable/ic_launcher" />

</LinearLayout>

My Activity will be looking like this

package com.example.sendingapplication;

import android.app.Activity;
import android.content.Intent;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.provider.MediaStore;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;

public class SendingActivity extends Activity {

	private static final int SELECT_PICTURE = 1;
	private String selectedImagePath;
	private ImageView img;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);

		img = (ImageView) findViewById(R.id.imageView1);
		Button send = (Button) findViewById(R.id.button1);
		send.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View arg0) {
				Intent sendIntent = new Intent();
				sendIntent.setAction(Intent.ACTION_SEND);
				sendIntent.putExtra(Intent.EXTRA_TEXT,
						"This is my text to send.");
				sendIntent.putExtra("MyKey",
						"This is second my text to send using my key.");
				sendIntent.setType("text/plain");
				startActivity(Intent.createChooser(sendIntent, "Send"));
			}
		});

		Button sendImage = (Button) findViewById(R.id.button2);
		sendImage.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View arg0) {
				Intent intent = new Intent();
				intent.setType("image/*");
				intent.setAction(Intent.ACTION_GET_CONTENT);
				startActivityForResult(
						Intent.createChooser(intent, "Select Picture"),
						SELECT_PICTURE);
			}
		});

	}

	public void onActivityResult(int requestCode, int resultCode, Intent data) {
		if (resultCode == RESULT_OK) {
			if (requestCode == SELECT_PICTURE) {
				Uri selectedImageUri = data.getData();
				selectedImagePath = getPath(selectedImageUri);
				System.out.println("Image Path : " + selectedImagePath);
				img.setImageURI(selectedImageUri);
				sendImage(selectedImageUri);
			}
		}
	}

	void sendImage(Uri selectedImageUri) {
		Intent shareIntent = new Intent();
		shareIntent.setAction(Intent.ACTION_SEND);
		shareIntent.putExtra(Intent.EXTRA_STREAM, selectedImageUri);
		shareIntent.setType("image/*");
		startActivity(Intent.createChooser(shareIntent, "Send Image"));
	}

	public String getPath(Uri uri) {
		String[] projection = { MediaStore.Images.Media.DATA };
		Cursor cursor = managedQuery(uri, projection, null, null, null);
		int column_index = cursor
				.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
		cursor.moveToFirst();
		return cursor.getString(column_index);
	}

}

Note that for sharing data we have to do nothing for the Sending Application.

Now Our Sending application is Over

RECEIVING APPLICATION STARTS.

This is my only activity in the Receiving application.

package com.example.receivingapplication;

import android.app.Activity;
import android.content.Intent;
import android.graphics.Bitmap;
import android.net.Uri;
import android.os.Bundle;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.TextView;

public class ReceivingActivity extends Activity {

	private Bitmap bitmap;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);

		LinearLayout lin = new LinearLayout(this);

		Intent intent = getIntent();
		String action = intent.getAction();
		String type = intent.getType();
		TextView tv = new TextView(this);
		lin.addView(tv);
		lin.setOrientation(LinearLayout.VERTICAL);
		if (Intent.ACTION_SEND.equals(action) && type != null) {
			if ("text/plain".equals(type)) {

				tv.setText(intent.getExtras().getString(Intent.EXTRA_TEXT));
				tv.append("\n" + (intent.getExtras().getString("MyKey")));

			} else if (type.startsWith("image/")) {
				if (bitmap != null) {
					bitmap.recycle();
				}
				ImageView img = new ImageView(this);
				Bundle bundle = intent.getExtras();
				Uri uri = (Uri) bundle.get(Intent.EXTRA_STREAM);
				img.setImageURI(uri);
				lin.addView(img);
		}

		} else {
			// Handle other intents, such as being started from the home screen
		}
		setContentView(lin);
	}
}

This is the AndroidManifest for the Receiving application.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.receivingapplication"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="17" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.example.receivingapplication.ReceivingActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
            <intent-filter>
                <action android:name="android.intent.action.SEND" />

                <category android:name="android.intent.category.DEFAULT" />

                <data android:mimeType="text/plain" />
            </intent-filter>
            <intent-filter>
                <action android:name="android.intent.action.SEND" />

                <category android:name="android.intent.category.DEFAULT" />

                <data android:mimeType="image/*" />
            </intent-filter>
        </activity>
    </application>

</manifest>

WATCH CAREFULLY THE INTENT FILTERS IN THE MANIFEST FOR THE RECEIVING ACTIVITY.
YOU CAN HAVE PLAIN TEXT, IMAGE OR MULTIPLE IMAGES SEND TO IT. I HAVE NOT WRITTEN CODE FOR SENDING MULTIPLE IMAGES NOW, IT WILL BE COMING IN THE NEXT UPDATE.

Hello everyone…

In this post I will show you how to listen to hardware button in an android smartphone.

This post especially shows how to listen to the home button in android. But my advice is never override the home button in your app.
Home button is to move the currently running process to background. But you can override the Backbutton and other buttons, android allows that on the keyDown Method. But if you try to match the “Home” button in the keyDown method it will not work. For that we have to follow another way which is shown in this post.

This simple java code handles the button pressed.

package test.test;

import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.WindowManager;

public class Test2Activity extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }
    
    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        if ((keyCode == KeyEvent.KEYCODE_HOME)) {
        	System.out.println("KEYCODE_HOME");
        	showDialog("'HOME'");
            return true;
        }
        if ((keyCode == KeyEvent.KEYCODE_BACK)) {
        	System.out.println("KEYCODE_BACK");
        	showDialog("'BACK'");
            return true;
        }
        if ((keyCode == KeyEvent.KEYCODE_MENU)) {
        	System.out.println("KEYCODE_MENU");
        	showDialog("'MENU'");
            return true;
        }
        return false;
    }
    
    void showDialog(String the_key){
    	AlertDialog.Builder builder = new AlertDialog.Builder(this);
    	builder.setMessage("You have pressed the " + the_key + " button. Would you like to exit the app?")
    		  .setCancelable(true)
    	       .setPositiveButton("OK", new DialogInterface.OnClickListener() {
    	           public void onClick(DialogInterface dialog, int id) {
    	        	   dialog.cancel();
    	        	   finish();
    	           }
    	       })
    	       .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
    	           public void onClick(DialogInterface dialog, int id) {
    	                dialog.cancel();
    	           }
    	       });
    	AlertDialog alert = builder.create();
    	alert.setTitle("CoderzHeaven.");
    	alert.show();
    }
    
    @Override
    public void onAttachedToWindow() {
        super.onAttachedToWindow();
        this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);           
    }
    
    public void onUserLeaveHint() { // this only executes when Home is selected.
    	// do stuff
    	super.onUserLeaveHint();
    	System.out.println("HOMEEEEEEEEE");
    }
}

When “onUserLeaveHint()” function is defined you can actually listen to the home button press and do some saving of data or something.

 public void onUserLeaveHint() { // this only executes when Home is selected.
    	// do stuff
    	super.onUserLeaveHint();
    	System.out.println("HOMEEEEEEEEE");
    }

Hello everyone,
Here is a simple example showing how to change the theme of default AlertDialog in android.

To start first create a fresh project named AlertTest.
In the AlertTestDemo.java file copy this code

package com.coderzheaven.pack;

import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.content.DialogInterface.OnClickListener;
import android.os.Bundle;

public class AlertTestDemo extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        AlertDialog dialog = new CustomDialog(this);
        dialog.setButton("OK", new OnClickListener()
        {
            public void onClick(DialogInterface arg0, int arg1)
            {
            }
        });
        dialog.setTitle("Coderzheaven");
        dialog.setMessage("Heaven of all working codes!! n Keep Visiting..n" +
        		"Thankyou.");
        dialog.show();
    }
}

Now create a file named “styles.xml” inside the res/values folder and copy this code into it.

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <style name="CenterTextView" parent="@android:style/Widget.TextView">
        <item name="android:gravity">center|center_vertical</item>
    </style>

    <style name="CenterJustifyDialogTitle" parent="@android:style/DialogWindowTitle" >
         <item name="android:gravity">center|center_vertical</item>
         <item name="android:textColor">#000000</item>
    </style>

	<style name="CenterJustifyTheme1" parent="@android:style/Theme.Translucent">
        <item name="android:textViewStyle">@style/CenterTextView</item>
        <item name="android:windowTitleStyle">@style/CenterJustifyDialogTitle</item>
    </style>

    <style name="CenterJustifyTheme2" parent="@android:style/Theme.Black">
        <item name="android:textViewStyle">@style/CenterTextView</item>
        <item name="android:windowTitleStyle">@style/CenterJustifyDialogTitle</item>
    </style>

    <style name="CenterJustifyTheme3" parent="@android:style/Theme.Light">
        <item name="android:textViewStyle">@style/CenterTextView</item>
        <item name="android:windowTitleStyle">@style/CenterJustifyDialogTitle</item>
    </style>

</resources>

Now create another java file named “CustomDialog.java” and copy this code into it.
We will apply the theme through this java file.
The theme is located and named in the above xml file.

package com.coderzheaven.pack;
import android.app.AlertDialog;
import android.content.Context;
import com.coderzheaven.pack.R;


public class CustomDialog extends AlertDialog {
		public CustomDialog(Context ctx)
		{
			super(ctx, R.style.CenterJustifyTheme1);
		}
}

Hello android lovers,

In today’s tutorial I will show you how to

1. Create a text file and save a textfile in your SDCARD in your preferred path.

2. Read the contents from the same file and show it in a TextView.

For writing a file we use the FileWriter class and for reading the textfile we use the FileReader class.
Now Let’s check out how we do this .

First create a fresh project and name it “saveFileDemo”.
In the “saveFileDemo.java” file copy this contents.

package com.coderzheaven.pack;

import java.io.FileReader;
import java.io.FileWriter;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

public class saveFileDemo extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        createFile();
        String file_contents = readFile();
    	System.out.println("FILE CONTENTS :  "  + file_contents);

    	TextView tv = (TextView)findViewById(R.id.tv);
    	tv.setText("Read File contents from SDCARD : n" + file_contents);
    }
    public void createFile(){
    	FileWriter fWriter;
        try{
             fWriter = new FileWriter("/sdcard/myfile.txt");
             fWriter.write("My file contents");
             fWriter.flush();
             fWriter.close();
         }catch(Exception e){
                  e.printStackTrace();
         }
    }
    public String readFile(){
        char buf[] = new char[512];
        FileReader rdr;
        String contents = "";
		try {
			rdr = new FileReader("/sdcard/myfile.txt");
			int s = rdr.read(buf);
			for(int k = 0; k < s; k++){
				contents+=buf[k];
			}
		} catch (Exception e) {
			e.printStackTrace();
		}
		return contents;
    }
}

This is the main.xml file contents.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView
	android:id = "@+id/tv"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/hello"
    />
</LinearLayout>

Here is the Strings.xml file contents

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="hello">Hello World, saveFileDemo!</string>
    <string name="app_name">saveFileDemo from Coderzheaven</string>
</resources>

Now the AndroidManifest.xml file contents.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.coderzheaven.pack"
      android:versionCode="1"
      android:versionName="1.0">
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".saveFileDemo"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
</manifest>

You can actually see the file by going to the FileExplorer and expanding the mnt folder(or simply SDCARD in older versions) and the SDCARD folder.
See the screenshot.

Check this link to see the contents of this file manually.

Hi all…….

All of you may be familiar with TextViews in ANDROID.
But how many of you know that we have have html as text in a textView. This post is a simple example to show this.

Create a fresh project and copy this code to the main java file.

package com.coderzheaven;

import android.app.Activity;
import android.os.Bundle;
import android.text.Html;
import android.text.method.LinkMovementMethod;
import android.widget.TextView;

public class TextViewLinkDemo extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        TextView tv = (TextView) findViewById(R.id.tv);
        tv.setText( Html.fromHtml("<b>This is a textView with a link </b>  " +
                    " <br /> <a href="http://www.coderzheaven.com">Coderzheaven</a> " +
                    "created in the Java source code using HTML."));
         tv.setMovementMethod(LinkMovementMethod.getInstance());
    }
}

The main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView
	android:id="@+id/tv"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/hello"
    />
</LinearLayout>

The AndroidManifest.xml file

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.coderzheaven"
      android:versionCode="1"
      android:versionName="1.0">
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".TextViewLinkDemo"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
</manifest>

Link in TextView Demo

Hi all…..
Splitting a string in android is really easy.checkout the following snippet.

package com.coderzheaven;

import android.app.Activity;
import android.os.Bundle;

public class SplitStringDemo extends Activity {
    String str = "India, USA, Japan, Russia, France";
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        String arr[] = str.split(",");
        for(int i = 0; i < arr.length; i++){
        	System.out.println("arr["+i+"] = " + arr[i].trim());
        }
    }
}

Check the Logcat for output.
Note: Make sure to put the escape character before the delimiter for splitting,otherwise the output may be each character.

This is a simple example that shows how many bytes are free in your SDCard.
Inorder to run this example, you have to create an SDCard and start the emulator with the SDCard.

Now create a fresh project and name it “FreeSpaceActivity.java” and copy the following code to it.

package pack.coderzheaven.check_space;

import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;
import android.os.Environment;
import android.os.StatFs;
import android.widget.TextView;

public class FreeSpaceActivity extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        StatFs stat_fs = new StatFs(Environment.getExternalStorageDirectory().getPath());
        double avail_sd_space = (double)stat_fs.getAvailableBlocks() *(double)stat_fs.getBlockSize();
        double GB_Available = (avail_sd_space / 1073741824);
        System.out.println("Available GB : " + GB_Available);

        TextView tv = (TextView)findViewById(R.id.tv);
        tv.setText("Your SD Card is " + GB_Available + " bytes free." );
        tv.setTextColor(Color.GREEN);
        tv.setTextSize(20);
    }
}

The main.xml file

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text=""
    android:id="@+id/tv"
    />
</LinearLayout>

AndroidManifest file

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="pack.coderzheaven.check_space"
      android:versionCode="1"
      android:versionName="1.0">

Free Space in SD Card

Hello everyone……..

In this simple example I will show you how to use Text To Speech in ANDROID. This is one of the unique features in ANDROID.
Unlike iPhone , ANDROID has a built in TTS Library which supports many languages. But iPhone doesn’t have this feature. They have to depend on third-party software for implementing this.

Now go on create a fresh project and copy this following code to it.

package com.TTS;
import java.util.Locale;
import android.app.Activity;
import android.os.Bundle;
import android.speech.tts.TextToSpeech;

public class TTS extends Activity implements TextToSpeech.OnInitListener {

	  TextToSpeech tts;
	  @Override
	  public void onCreate(Bundle savedInstanceState) {
	    super.onCreate(savedInstanceState);
	    setContentView(R.layout.main);
	    tts = new TextToSpeech(this,this);
	  }

	  public void onInit(int status) {
	    Locale loc = new Locale("eng", "","");
	    if(tts.isLanguageAvailable(loc) >= TextToSpeech.LANG_AVAILABLE){
	      tts.setLanguage(loc);
	    }
	    tts.speak("Text to speech in ANDROID from coderzheaven, Hope you like it.", TextToSpeech.QUEUE_FLUSH, null);
	  }

	  @Override
	  protected void onDestroy() {
	    super.onDestroy();
	    tts.shutdown();
	  }
}

After running this application you will hear the sound that is given as text in this line.

tts.speak(“Text to speech in ANDROID from coderzheaven, Hope you like it.”, TextToSpeech.QUEUE_FLUSH, null);

Hi all,In this tutorial I will show you how to open browser from an ANDROID application.
This is done through intents. You know that intents are used to invoke other activities.
So we here invoke the browser activity.
The following code will open the default browser in your ANDROID phone.

package com.myPackage;

import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;

public class OpenURL extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        String url = "http://www.google.com/";
        Intent i = new Intent(Intent.ACTION_VIEW);
        i.setData(Uri.parse(url));
        startActivity(i);
    }
}

This is the manifest file for the above code.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.Open"
      android:versionCode="1"
      android:versionName="1.0">
    <application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".OpenClass"
                  android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>
</manifest>

Playing a video file is simple in android. This post will help you.
Put your video in res/raw folder. If no raw folder present then create a new folder inside res.

package com.coderzheaven.pack;

import android.app.Activity;
import android.net.Uri;
import android.os.Bundle;
import android.widget.MediaController;
import android.widget.VideoView;

public class Example extends Activity {
    /** Called when the activity is first created. */
	public void onCreate(Bundle savedInstanceState)
        {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.main);
           showVideo();
       }
	private void showVideo()
	{
		VideoView vd = (VideoView)findViewById(R.id.videoview);
		Uri uri = Uri.parse("android.resource://package/"+R.raw.movie);
		MediaController mc = new MediaController(this);
		vd.setMediaController(mc);
		vd.setVideoURI(uri);
		vd.start();
	}
}

The main. xml file.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
android:id="@+id/widget32"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
	<VideoView
			android:id="@+id/videoview"
			android:layout_width="fill_parent"
			android:layout_height="fill_parent"
			android:layout_alignParentTop="true"
			>
		</VideoView>
</RelativeLayout>

The following code helps you to do a drag and drop in ANDROID.

import android.widget.ImageView;

public class Touch extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
MyView tx = new MyView(this);
MyView2 tx2 = new MyView2(this);
tx.setText("Drag Me");
int imgID = getResources().getIdentifier("icon", "drawable", "com.pack");
tx2.setImageResource(imgID);
AbsoluteLayout l = new AbsoluteLayout(this);

AbsoluteLayout.LayoutParams p = new AbsoluteLayout.LayoutParams(
AbsoluteLayout.LayoutParams.WRAP_CONTENT,
AbsoluteLayout.LayoutParams.WRAP_CONTENT,0,0);
l.addView(tx,p);
l.addView(tx2,p);
setContentView(l);

}
