注：

AdapterViewFlipper 不能直接添加监听


ViewFlipper的使用

package com.example.android_viewflipper;



import android.app.Activity;

import android.os.Bundle;

import android.view.GestureDetector;

import android.view.GestureDetector.OnGestureListener;

import android.view.MotionEvent;

import android.widget.ImageView;

import android.widget.ViewFlipper;



public class MainActivity extends Activity implements OnGestureListener {

    ViewFlipper flipper;

    GestureDetector mGestureDetector;



    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        flipper = (ViewFlipper) findViewById(R.id.flipper);

        ImageView imageView = new ImageView(getApplicationContext());

        imageView.setBackgroundResource(R.drawable.ic_launcher);

        flipper.addView(imageView);

        // 手势

        mGestureDetector = new GestureDetector(this);

    }



    @Override

    public boolean onTouchEvent(MotionEvent event) {

        return mGestureDetector.onTouchEvent(event);

    }



    @Override

    public boolean onDown(MotionEvent e) {

        // TODO Auto-generated method stub

        return false;

    }



    @Override

    public void onShowPress(MotionEvent e) {

        // TODO Auto-generated method stub



    }



    @Override

    public boolean onSingleTapUp(MotionEvent e) {

        // TODO Auto-generated method stub

        return false;

    }



    @Override

    public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX,

            float distanceY) {

        // TODO Auto-generated method stub

        return false;

    }



    @Override

    public void onLongPress(MotionEvent e) {

        // TODO Auto-generated method stub



    }



    /**

     * 滑动变换图片

     */

    public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,

            float velocityY) {

        if (e2.getX() - e1.getX() > 100) {

            flipper.showPrevious();

        } else if (e2.getX() - e1.getX() < 100) {

            flipper.showNext();

        }

        return false;

    }
