第一步：layout文件

<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"    tools:context="${relativePackage}.${activityClass}" >    <ViewFlipper        android:id="@+id/viewflipper"        android:layout_width="match_parent"        android:layout_height="match_parent" >    </ViewFlipper></RelativeLayout>

第二步：java文件

package com.example.testviewflipper;import android.R.integer;import android.app.Activity;import android.os.Bundle;import android.util.Log;import android.view.Menu;import android.view.MenuItem;import android.view.MotionEvent;import android.view.View;import android.view.View.OnClickListener;import android.view.View.OnTouchListener;import android.widget.ImageView;import android.widget.Toast;import android.widget.ViewFlipper;public class MainActivity extends Activity {ViewFlipper viewFlipper;float startX = 0;ImageView imageView1;ImageView imageView2;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);viewFlipper = (ViewFlipper) findViewById(R.id.viewflipper);/** * 数据源 */imageView1 = new ImageView(this);imageView1.setBackgroundResource(R.drawable.pic1);imageView2 = new ImageView(this);imageView2.setBackgroundResource(R.drawable.pic2);/** * 添加子view */viewFlipper.addView(imageView1);viewFlipper.addView(imageView2);/** * 设置view切换的动画 */// viewFlipper.setInAnimation(inAnimation);// viewFlipper.setOutAnimation(outAnimation);/** * 设置view切换的时间间隔 */ viewFlipper.setFlipInterval(2000);  /**  * view开始切换  */ viewFlipper.startFlipping();  /**  * 设置左右滑动事件以及点击事件  */viewFlipper.setOnTouchListener(new OnTouchListener() {@Overridepublic boolean onTouch(View v, MotionEvent event) {// TODO Auto-generated method stubswitch (event.getAction()) {case MotionEvent.ACTION_DOWN:startX = event.getX();break;case MotionEvent.ACTION_MOVE:break;case MotionEvent.ACTION_UP:/** * 点击事件 */if ((event.getX() - startX) == 0) {if (imageView1 == viewFlipper.getCurrentView()) {Toast.makeText(MainActivity.this, "您选择了第一张图片", 2000).show();}if (imageView2 == viewFlipper.getCurrentView()) {Toast.makeText(MainActivity.this, "您选择了第二张图片", 2000).show();}}/** * 向右滑动 */if ((event.getX() - startX) > 100) {viewFlipper.showNext();}/** * 向左滑动 */if ((startX - event.getX()) > 100) {viewFlipper.showPrevious();}break;default:break;}return true;}});}}
