布局：

<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="com.example.adapterviewflipper.MainActivity" >    <AdapterViewFlipper         android:id="@+id/flipper"        android:layout_height="match_parent"        android:layout_width="match_parent"        android:flipInterval="3000"        android:layout_alignParentTop="true"></AdapterViewFlipper>        <Button         android:id="@+id/last"        android:text="上一个"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_alignParentLeft="true"        android:layout_alignParentBottom="true"/>        <Button         android:id="@+id/auto"        android:text="自动"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_alignParentBottom="true"        android:layout_toRightOf="@id/last"        android:layout_marginLeft="10dp"/>        <Button         android:id="@+id/next"        android:text="下一个"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_alignParentBottom="true"        android:layout_toRightOf="@id/auto"        android:layout_marginLeft="10dp"/></RelativeLayout>

主Activity

package com.example.adapterviewflipper;import android.app.Activity;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.view.ViewGroup;import android.view.ViewGroup.LayoutParams;import android.widget.AdapterViewFlipper;import android.widget.BaseAdapter;import android.widget.Button;import android.widget.ImageView;public class MainActivity extends Activity {private int img[] = {R.drawable.img,R.drawable.img2,R.drawable.img3,R.drawable.img4} ;private Button next,auto ,last;private AdapterViewFlipper flipper  ;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);this.flipper = (AdapterViewFlipper)findViewById(R.id.flipper) ;this.last = (Button)findViewById(R.id.last) ;this.next = (Button)findViewById(R.id.next) ;this.auto = (Button)findViewById(R.id.auto) ;BaseAdapter adapter = new BaseAdapter() {@Overridepublic View getView(int position, View convertView, ViewGroup parent) {// TODO Auto-generated method stubImageView image = new ImageView(getApplicationContext()) ;image.setImageResource(img[position]);image.setScaleType(ImageView.ScaleType.FIT_XY);image.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,LayoutParams.MATCH_PARENT));return image ;}@Overridepublic long getItemId(int position) {// TODO Auto-generated method stubreturn position;}@Overridepublic Object getItem(int position) {// TODO Auto-generated method stubreturn position;}@Overridepublic int getCount() {// TODO Auto-generated method stubreturn img.length;}};this.flipper.setAdapter(adapter);addListener() ;}private void addListener() {this.last.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {flipper.showNext();flipper.stopFlipping();}});this.next.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {flipper.showPrevious();flipper.stopFlipping();}});this.auto.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {flipper.startFlipping();}});}     }

效果图，一个类似于相册的程序。
