Create two more XML for flipin and flipout in reverse direction:
/res/anim/flipin_reverse.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/overshoot_interpolator">
<translate
android:fromXDelta="-100%p"
android:toXDelta="0"
android:duration="500"/>
</set>
/res/anim/flipout_reverse.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/overshoot_interpolator">
<translate
android:fromXDelta="0"
android:toXDelta="100%p"
android:duration="500"/>
</set>
Modify main.xml to add button of flip to previous page, and remove android:inAnimation and android:outAnimation of ViewFlipper.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

Modify code of the activity:
package com.exercise.AndroidViewFlipper;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.animation.Animation;
import android.view.animation.AnimationUtils;
import android.widget.Button;
import android.widget.ViewFlipper;
public class AndroidViewFlipperActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
final ViewFlipper page = (ViewFlipper)findViewById(R.id.flipper);
Button btnNext = (Button)findViewById(R.id.next);
Button btnPrevious = (Button)findViewById(R.id.previous);
final Animation animFlipInForeward = AnimationUtils.loadAnimation(this, R.anim.flipin);
final Animation animFlipOutForeward = AnimationUtils.loadAnimation(this, R.anim.flipout);
final Animation animFlipInBackward = AnimationUtils.loadAnimation(this, R.anim.flipin_reverse);
final Animation animFlipOutBackward = AnimationUtils.loadAnimation(this, R.anim.flipout_reverse);
btnNext.setOnClickListener(new Button.OnClickListener(){
@Override
public void onClick(View arg0) {
page.setInAnimation(animFlipInForeward);
page.setOutAnimation(animFlipOutForeward);
page.showNext();
}});
btnPrevious.setOnClickListener(new Button.OnClickListener(){
@Override
public void onClick(View arg0) {
page.setInAnimation(animFlipInBackward);
page.setOutAnimation(animFlipOutBackward);
page.showPrevious();
}});
}
}
