WaveLayout in Android

Step 1:Create new android project in eclips.
File/new project/android project/waveLayoutActivity.

Step 2:Create wave_layout.xml and wave_scale.xml in @res/anim
wave_layout.xml:
<?xml version="1.0" encoding="utf-8"?>
<gridLayoutAnimation xmlns:android="http://schemas.android.com/apk/res/android"
       android:rowDelay="75%"
       android:columnDelay="0%"
       android:directionPriority="none"
       android:animation="@anim/wave_scale" />



wave_scale.xml:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
        android:interpolator="@android:anim/accelerate_interpolator">
        <alpha android:fromAlpha="0.0" android:toAlpha="1.0"
                android:duration="100" />
        <scale android:fromXScale="0.5" android:toXScale="1.5"
                android:fromYScale="0.5" android:toYScale="1.5" android:pivotX="50%"
                android:pivotY="50%" android:duration="200" />
        <scale android:fromXScale="1.5" android:toXScale="1.0"
                android:fromYScale="1.5" android:toYScale="1.0" android:pivotX="50%"
                android:pivotY="50%" android:startOffset="200" android:duration="100" />
</set>

Step 3:Edit waveLayoutActivity class as like
package com.empmark.wavelayout;

import java.util.List;
import android.app.Activity;
import android.content.Intent;
import android.content.pm.ResolveInfo;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;

public class WaveLayoutActivity extends Activity {
    private List<ResolveInfo> mApps;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Intent mainIntent = new Intent(Intent.ACTION_MAIN, null);
        mainIntent.addCategory(Intent.CATEGORY_LAUNCHER);
        mApps = getPackageManager().queryIntentActivities(mainIntent, 0);
        setContentView(R.layout.main);
        GridView grid = (GridView) findViewById(R.id.grid);
        grid.setAdapter(new AppsAdapter());
    }
    public class AppsAdapter extends BaseAdapter {
        public View getView(int position, View convertView, ViewGroup parent) {
            ImageView i = new ImageView(WaveLayoutActivity.this);
            ResolveInfo info = mApps.get(position % mApps.size());
            i.setImageDrawable(info.activityInfo.loadIcon(getPackageManager()));
            i.setScaleType(ImageView.ScaleType.FIT_CENTER);
            i.setLayoutParams(new GridView.LayoutParams(36, 36));
            return i;
        }
        public final int getCount() {
            return Math.min(32, mApps.size());
        }
        public final Object getItem(int position) {
            return mApps.get(position % mApps.size());
        }
        public final long getItemId(int position) {
            return position;
        }
    }
}

Step 4:no need to edit anything in androidmanifest.xml.

Step 5:save project and run in emulator.

Step 6:You'll get an output like as...
