ViewFlipper
Android系统自带的一个多页面管理控件，它可以实现子界面的自动切换
为ViewFlipper加入View
静态导入：在layout布局中直接导入（不推荐，不够灵活）
<ViewFilpper
android:id="@+id/flipper"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:flipInterval="4000" >
<ImageView
android:scaleType="matrix"
android:id="@+id/ex2"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<ImageView
android:scaleType="matrix"
android:id="@+id/ex3"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<ImageView
android:scaleType="matrix"
android:id="@+id/ex4"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</ViewFlipper>
动态导入：addView()方法
flipper = (ViewFlipper) findViewById(R.id.flipper);
flipper.addView(getImageView(R.drawable.pic1));
flipper.addView(getImageView(R.drawable.pic2));
flipper.addView(getImageView(R.drawable.pic3));
flipper.addView(getImageView(R.drawable.pic4));
ViewFlipper常用方法
setInAnimation：设置View进入屏幕时候使用的动画
setOutAnimation：设置View退出屏幕时候使用的动画
showNext：调用该函数来显示ViewFlipper里面的下一个View
showPrevious：调用该函数来显示ViewFlipper里面的上一个View
setFlipInterval：设置View之间切换的时间间隔
startFlipping：使用上面设置的时间间隔来切换所有的View，切换回循环进行
stopFlipping：停止View切换
利用ViewFlipper实现图片轮播

支持手势滑动的ViewFlipper
public class MainActivity extends AppCompatActivity {private ViewFlipper flipper;private int[] resId = {R.drawable.pic1, R.drawable.pic2, R.drawable.pic3, R.drawable.pic4};private float startX;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);flipper = (ViewFlipper) findViewById(R.id.flipper);//动态导入的方式为ViewFlipper加入子Viewfor (int i = 0; i < resId.length; i++) {flipper.addView(getImageView(resId[i]));}// //为ViewFlipper添加动画效果// flipper.setInAnimation(this, R.anim.left_in);// flipper.setOutAnimation(this, R.anim.left_out);// //设定ViewFlipper视图切换的时间间隔// flipper.setFlipInterval(3000);// //开始播放// flipper.startFlipping();}@Overridepublic boolean onTouchEvent(MotionEvent event) {switch(event.getAction()) {//手指落下case MotionEvent.ACTION_DOWN:startX = event.getX();break;//手指滑动case MotionEvent.ACTION_MOVE:break;//手指离开case MotionEvent.ACTION_UP://向右滑动（看前一页）if (event.getX() - startX > 100) {//flipper.setInAnimation(this, R.anim.left_in);//flipper.setInAnimation(this, R.anim.left_out);flipper.showPrevious();//显示前一页}//向左滑动（看后一页）if (startX - event.getX() > 100) {//flipper.setInAnimation(this, R.anim.right_in);//flipper.setInAnimation(this, R.anim.right_out);flipper.showNext();//显示后一页}break;}return super.onTouchEvent(event);}private ImageView getImageView(int resId) {ImageView image = new ImageView(this);//按图片宽高// image.setImageResource(resId);//铺满整个屏幕image.setBackgroundResource(resId);return image;}}
