GridView Animation In Android

The Android Development Tutorials blog contains Basic as well as Advanced android tutorials.Go to Android Development Tutorials to get list of all Android Tutorials.


In Android we can animate a GridView  to make it more interactive and enhance the user experience.

To animate a GridView we need animation resource.

In this Example I have used two types of Animation.
Type 1: GridView will come In on Screen from  Top Left corner. (fly_in_from_top_corner.xml has been used for this)  See Snapshot 1 below
Type 2: GridView will come In on Screen from  Center of the Screen.(fly_in_from_center.xml has been used for this)  See Snapshot 2 below

To learn Basic of Android Animation  go to  Android Animation Tutorial

Animation  Resources


<set xmlns:android="" android:shareInterpolator="true">
    <scale android:interpolator="@android:anim/decelerate_interpolator"
           android:fromXScale="0.0" android:toXScale="1.0"
           android:fromYScale="0.0" android:toYScale="1.0"
           android:pivotX="100%" android:pivotY="0%"
           android:fillAfter="false" android:duration="5000"/>


<set xmlns:android="" android:shareInterpolator="true">
    <scale android:interpolator="@android:anim/decelerate_interpolator"
           android:fromXScale="1.0" android:toXScale="0.0"
           android:fromYScale="1.0" android:toYScale="0.0"
           android:pivotX="50%" android:pivotY="50%"
           android:fillAfter="false" android:duration="1000"/>

Create a new Folder "anim" inside  "res" folder and put these two animation resource files in "anim" folder

                                                                  Snapshot 2: GridView is Coming from Center



public class MainActivity extends Activity
     static final String[] numbers = new String[] {
           "A", "B", "C", "D", "E",
           "F", "G", "H", "I", "J",
           "K", "L", "M", "N", "O",
           "P", "Q", "R", "S", "T",
           "U", "V", "W", "X", "Y", "Z"};

             GridView gridView;
            protected void onCreate(Bundle savedInstanceState)
                        // Create the ArrayAdapter
                        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                                android.R.layout.simple_list_item_1, numbers);
                        // Set the Adapter to GridView
                        // Set the Required Animation to GridView and start the Animation

                        // use fly_in_from_center to have 2nd type of animation effect (snapshot 2)
                        Animation anim = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.fly_in_from_top_corner);
