How to create a Slide from Left animation while deleting a row from a ListView in Android?

By | September 12, 2012

Hello all……

I have written a lost of posts on Listviews. You can see that by just searching Listviews in my site. Today I will show you how to create a slide out animation while we delete a row from a ListView.

So this is the xml that contains the ListView. Let it be in the main.xml

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">
  
	<ListView android:layout_width="fill_parent" 
	  android:layout_height="fill_parent" 
	  android:id="@+id/mainListView">
	</ListView>
	
</LinearLayout>

Create another file inside the layout folder named “simplerow.xml”.

simplerow.xml

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
 android:id="@+id/rowTextView" 
 android:layout_width="fill_parent" 
 android:layout_height="wrap_content"
 android:padding="10dp"
 android:textSize="16sp" >
</TextView>

OK our xml part is over. Now the java part.

This is the main java file that implements this xml.

“SimpleListViewActivity.java”

package com.coderzheaven.pack;

import java.util.ArrayList;

import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.view.View;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;

public class SimpleListViewActivity extends Activity {
  
  private ListView mainListView ;
  private ArrayAdapter<String> listAdapter ;
   ArrayList<String> all_planets = 
       new ArrayList<String>(){      
           private static final long serialVersionUID = -1773393753338094625L;
           {
               add("Mercury ");
               add("Venus "); 
               add("Earth"); 
               add("Mars"); 
               add("Jupiter"); 
               add("Saturn"); 
               add("Uranus"); 
               add("Neptune"); 
               add("Pluto"); 
           }
   };
   
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);    
  
    mainListView = (ListView) findViewById( R.id.mainListView );

    listAdapter = new ArrayAdapter<String>(this, R.layout.simplerow, all_planets);

    mainListView.setAdapter( listAdapter );  
    
    mainListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View rowView, int positon,long id) {
            Toast.makeText(rowView.getContext(), ""+positon, Toast.LENGTH_LONG).show();
            removeListItem(rowView,positon);
        }
    });
    
  }
  
  protected void removeListItem(View rowView, final int positon) {

      final Animation animation = AnimationUtils.loadAnimation(SimpleListViewActivity.this,android.R.anim.slide_out_right); 
      rowView.startAnimation(animation);
      Handler handle = new Handler();
      handle.postDelayed(new Runnable() {

		@Override
          public void run() {
        	  all_planets.remove(positon);
              listAdapter.notifyDataSetChanged();
              animation.cancel();
          }
      },1000);

  }

}

OK Done. Now run it and see the result.
