Step 2 : Open res -> layout -> activity_main.xml (or) main.xml and add following code :

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="@string/hello_world" />

    <Button
        android:id="@+id/Scale"
        android:layout_width="100dp"
        android:layout_height="wrap_content"
        android:layout_below="@+id/Alpha"
        android:layout_toLeftOf="@+id/Translate"
        android:text="Scale" />

    <Button
        android:id="@+id/Translate"
        android:layout_width="100dp"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/Rotate"
        android:layout_below="@+id/Alpha"
        android:text="Translate" />

    <Button
        android:id="@+id/Complex"
        android:layout_width="100dp"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"
        android:layout_marginBottom="50dp"
        android:layout_marginRight="14dp"
        android:text="Complex" />

    <Button
        android:id="@+id/Rotate"
        android:layout_width="100dp"
        android:layout_height="wrap_content"
        android:layout_alignBaseline="@+id/Complex"
        android:layout_alignBottom="@+id/Complex"
        android:layout_toLeftOf="@+id/Complex"
        android:text="Rotate" />

    <Button
        android:id="@+id/Alpha"
        android:layout_width="100dp"
        android:layout_height="wrap_content"
        android:layout_alignBaseline="@+id/Rotate"
        android:layout_alignBottom="@+id/Rotate"
        android:layout_toLeftOf="@+id/Rotate"
        android:text="Alpha" />

    <ImageView
        android:id="@+id/imageView"
        android:layout_width="100dp"
        android:layout_height="100dp"
        android:layout_alignRight="@+id/Rotate"
        android:layout_below="@+id/textView1"
        android:layout_marginRight="46dp"
        android:layout_marginTop="67dp"
        android:src="@drawable/ic_launcher" />

</RelativeLayout>


Step 3 : Open src -> package -> alpha.xml and add following code :

<?xml version="1.0" encoding="utf-8"?>
<alpha 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromAlpha="1" android:toAlpha="0.3" android:duration="2000" android:repeatCount="3">
</alpha>

Step 4 : Open src -> package -> MainActivity.java and add following code :

package com.gudivada.hemanthsomaraju;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.animation.AlphaAnimation;
import android.view.animation.Animation;
import android.view.animation.AnimationSet;
import android.view.animation.AnimationUtils;
import android.view.animation.ScaleAnimation;
import android.view.animation.TranslateAnimation;
import android.view.animation.Animation.AnimationListener;
import android.view.animation.RotateAnimation;
import android.widget.Button;
import android.widget.ImageView;
public class MainActivity extends Activity {
    private ImageView imageView;

    // define animationType enum
    enum AnimationType{
        Alpha,
        Rotate,
        Scale,
        Translate,
        Complex
    }

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        //define 4 button for each tween animation
        imageView = (ImageView)findViewById(R.id.imageView);
        Button alpha = (Button)findViewById(R.id.Alpha);
        alpha.setOnClickListener(new AnimationClickListener(AnimationType.Alpha));
        Button rotate = (Button)findViewById(R.id.Rotate);
        rotate.setOnClickListener(new AnimationClickListener(AnimationType.Rotate));
        Button scale = (Button)findViewById(R.id.Scale);
        scale.setOnClickListener(new AnimationClickListener(AnimationType.Scale));
        Button translate = (Button)findViewById(R.id.Translate);
        translate.setOnClickListener(new AnimationClickListener(AnimationType.Translate));
        Button complex = (Button)findViewById(R.id.Complex);
        complex.setOnClickListener(new AnimationClickListener(AnimationType.Complex));
    }
  
     

    // create a listener inner class
    class AnimationClickListener implements OnClickListener{
        private AnimationType animationType;
        public AnimationClickListener(AnimationType animType){
            animationType = animType;
        }
        public void onClick(View v) {
            // TODO Auto-generated method stub
            switch (animationType) {
            case Alpha:

                //Alpha animation. repeat 5 times, last for 1 mins               
                AlphaAnimation alphaAnimation = (AlphaAnimation)AnimationUtils.loadAnimation(MainActivity.this, R.layout.alpha);
                imageView.startAnimation(alphaAnimation);
                break;
            case Rotate:
                //rotate animation
                RotateAnimation rotateAnimation = new RotateAnimation(0, 360, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
                rotateAnimation.setDuration(3000);
                rotateAnimation.setRepeatCount(3);
                //start animation
                imageView.startAnimation(rotateAnimation);
                break;
            case Scale:
                //scale animation
                ScaleAnimation scaleAnimation = new ScaleAnimation(1, 1.5f, 1, 1.5f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
                scaleAnimation.setDuration(3000);
                scaleAnimation.setRepeatCount(3);
                //start animation
                imageView.startAnimation(scaleAnimation);
                break;
            case Translate:
                //translate animation
                TranslateAnimation translateAnimation = new TranslateAnimation(Animation.RELATIVE_TO_SELF, 0, Animation.RELATIVE_TO_SELF, 2, Animation.RELATIVE_TO_SELF, 0, Animation.RELATIVE_TO_SELF, 2);
                translateAnimation.setDuration(3000);
                translateAnimation.setRepeatCount(3);
                //start animation
                imageView.startAnimation(translateAnimation);
                break;
  
            case Complex:
                //four animation overlap
                AnimationSet sets = new AnimationSet(false);
                
                AlphaAnimation _animation1 = new AlphaAnimation(1f, 0.1f);
                _animation1.setDuration(3000);
                
                RotateAnimation rotateAnimation1 = new RotateAnimation(0, 360, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
                rotateAnimation1.setDuration(3000);
                
                ScaleAnimation scaleAnimation1 = new ScaleAnimation(1, 1.5f, 1, 1.5f, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
                scaleAnimation1.setDuration(3000);
                
                TranslateAnimation translateAnimation1 = new TranslateAnimation(Animation.RELATIVE_TO_SELF, 0, Animation.RELATIVE_TO_SELF, 2, Animation.RELATIVE_TO_SELF, 0, Animation.RELATIVE_TO_SELF, 2);
                translateAnimation1.setDuration(3000);
                
                sets.addAnimation(_animation1);
                sets.addAnimation(rotateAnimation1);
                sets.addAnimation(scaleAnimation1);
                sets.addAnimation(translateAnimation1);
                imageView.startAnimation(sets);
                break;
            default:
                break;
            }
        }
    }
} 


Step 5 : Open AndroidManifest.xml and add following code :

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

    <uses-sdk
        android:minSdkVersion="4"
         />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.gudivada.hemanthsomaraju.MainActivity"
            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>

Step 6 : Our output will be like this :
