Hello all

This is a simple post that shows How to pass an Object from One Activity to another in Android.

I am going to pass the following object from One Activity to another.

MyObject{
String name;
String website;
}

This is the class that defines the Object.

package com.coderzheaven.passarraylist;import android.os.Parcel;import android.os.Parcelable;public class MyObject implements Parcelable{String name,website;public MyObject(){}private MyObject(Parcel in){this.name = in.readString();this.website = in.readString();}public String getWebsite() {return website;}public void setWebsite(String website) {this.website = website;}public String getName() {return name;}public void setName(String name) {this.name = name;}@Overridepublic int describeContents() {return 0;}@Overridepublic void writeToParcel(Parcel dest, int flags) {dest.writeString(this.name);dest.writeString(this.website);}public static final MyObject.Creator<MyObject> CREATOR = new MyObject.Creator<MyObject>() {public MyObject createFromParcel(Parcel in) {return new MyObject(in);}public MyObject[] newArray(int size) {return new MyObject[size];}};}

This is the first activity that sends the object to second activity.

package com.coderzheaven.passarraylist;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.TextView;public class MainActivity extends Activity {@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);this.setTitle("Main Activity");final MyObject myobj = new MyObject();myobj.setName("Coderz");myobj.setWebsite("CoderzHeaven.com");TextView name = (TextView)findViewById(R.id.name);name.setText("Name : " + myobj.getName());TextView website = (TextView)findViewById(R.id.website);website.setText("Website : " + myobj.getWebsite());findViewById(R.id.button1).setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {Intent intent = new Intent(MainActivity.this, Second.class);intent.putExtra("myobject", myobj);startActivity(intent);}});}}

This is the second Activity.

package com.coderzheaven.passarraylist;import android.app.Activity;import android.os.Bundle;import android.widget.TextView;public class Second extends Activity {@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.second_activity);this.setTitle("Second Activity");Bundle b = getIntent().getExtras();if(b!=null){MyObject myobj = (MyObject)getIntent().getExtras().getParcelable("myobject");TextView name = (TextView)findViewById(R.id.name);name.setText("Name : " + myobj.getName());TextView website = (TextView)findViewById(R.id.website);website.setText("Website : " + myobj.getWebsite());}}}
