Java source code:

Package com. example. viewflipper; import android. OS. bundle; import android. app. activity; import android. view. menu; import android. view. motionEvent; import android. widget. viewFlipper; public class MainActivity extends Activity {private ViewFlipper viewflipper; private float startx, endx; @ Override protected void onCreate (Bundle savedInstanceState) {super. onCreate (savedInstanceState); setContentView (R. layout. activity_main); viewflipper = (ViewFlipper) findViewById (R. id. viewFlipper1);} public boolean onTouchEvent (MotionEvent event) {// method stub automatically generated by TODO int action = event. getAction (); if (action = MotionEvent. ACTION_DOWN) {startx = event. getX ();} else if (action = MotionEvent. ACTION_UP) {endx = event. getX (); if (startx-endx> 20) {viewflipper. setInAnimation (this, android. r. anim. fade_in); viewflipper. setOutAnimation (this, android. r. anim. fade_out);/* viewflipper. setInAnimation (this, R. layout. in_rightleft); viewflipper. setOutAnimation (this, R. layout. out_rightleft); */viewflipper. showNext ();} else if (endx-startx> 20) {/* viewflipper. setInAnimation (this, R. layout. in_leftright); viewflipper. setOutAnimation (this, R. layout. out_leftright); */viewflipper. setInAnimation (this, android. r. anim. fade_in); viewflipper. setOutAnimation (this, android. r. anim. fade_out); viewflipper. showPrevious () ;}} return super. onTouchEvent (event );}}

Use the ViewFlipper control layout:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    tools:context=".MainActivity" >    <ViewFlipper        android:id="@+id/viewFlipper1"        android:layout_width="match_parent"        android:layout_height="match_parent"         >          <LinearLayout        android:layout_width="match_parent"        android:layout_height="match_parent"        android:orientation="vertical" >        <ImageView            android:id="@+id/imageView1"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:src="@drawable/item1"            android:scaleType="centerCrop" />    </LinearLayout>    <LinearLayout        android:layout_width="match_parent"        android:layout_height="match_parent"        android:orientation="vertical" >        <ImageView            android:id="@+id/imageView2"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:src="@drawable/item2"            android:scaleType="centerCrop" />    </LinearLayout>    </ViewFlipper></RelativeLayout>

Run OK.
