需要注意的地方已在代码中表明

package cn.com.sxp;import android.app.Activity;import android.os.Bundle;import android.view.View;import android.view.ViewGroup;import android.widget.Button;import android.widget.ViewFlipper;public class ViewFlipperActivity extends Activity {// 该例子显示,一个viewFlipper加载了三个线性布局,每个线性布局包含一个button,一个imageView。// 这三个线性布局不是同时显示,是轮番显示,一个线性布局按照动画效果向左离去,另一个线性布局从右而来private ViewFlipper viewFlipper = null;Button btnOne = null, btnTwo = null, btnThree = null;/** Called when the activity is first created. */@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);btnOne = (Button) findViewById(R.id.btnOne);viewFlipper = (ViewFlipper) findViewById(R.id.vf);btnOne.setOnClickListener(new View.OnClickListener() {public void onClick(View view) {// 在layout中定义的属性,也可以在代码中指定// setInAnimation():// Specifies the animation 动画 used to animate a View that enters the screen.// Parameters// context  The application's environment. // resourceID  The resource id of the animation. // // Return the context of the single, global Application object of the current process. This // generally should only be used if you need a Context whose lifecycle is separate from the // current context, that is tied to the lifetime of the process rather than the current // component. // viewFlipper.setInAnimation(getApplicationContext(), R.anim.push_left_in);// setOutAnimation():// Specifies the animation used to animate a View that exit the screen.// viewFlipper.setOutAnimation(getApplicationContext(), R.anim.push_left_out);// setPersistentDrawingCache():// Indicates what types of drawing caches should be kept in memory after they have been // created.// viewFlipper.setPersistentDrawingCache(ViewGroup.PERSISTENT_ALL_CACHES);// setFlipInterval();// How long to wait before flipping to the next view// viewFlipper.setFlipInterval(1000);// showNext()// Manually shows the next child. // viewFlipper.showNext();// 调用下面的函数将会循环显示mViewFlipper内的所有View。// mViewFlipper.startFlipping();}});btnTwo = (Button) findViewById(R.id.btnTwo);btnTwo.setOnClickListener(new View.OnClickListener() {public void onClick(View view) {viewFlipper.showNext();}});btnThree = (Button) findViewById(R.id.btnThree);btnThree.setOnClickListener(new View.OnClickListener() {public void onClick(View view) {viewFlipper.showNext();}});}}

  运行效果如下;
