VideoView 开始暂停监听

现在做个视频播放器，当暂停的时候要在界面上弹出一张图片，找了半天，发现VideoView没有暂停播放的监听发方法，从网上找了下资料，需要重写VideoView这个类

以下代码是网上的

 首先写一个CustomVideoView类：package our.english.listening;import android.content.Context;import android.util.AttributeSet;import android.widget.VideoView;public class CustomVideoView extends VideoView {    private PlayPauseListener mListener;    public CustomVideoView(Context context) {        super(context);    }    public CustomVideoView(Context context, AttributeSet attrs) {        super(context, attrs);    }    public CustomVideoView(Context context, AttributeSet attrs, int defStyle) {        super(context, attrs, defStyle);    }    public void setPlayPauseListener(PlayPauseListener listener) {        mListener = listener;    }    @Override    public void pause() {        super.pause();        if (mListener != null) {            mListener.onPause();        }    }    @Override    public void start() {        super.start();        if (mListener != null) {            mListener.onPlay();        }    }    interface PlayPauseListener {        void onPlay();        void onPause();    }}在Activity类里从XML取得VideoView：CustomVideoView video = (CustomVideoView)findViewById(R.id.videoview);注意XML中的VideoView应该这样写：        <our.english.listening.CustomVideoView        android:id="@+id/videoview"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:visibility="visible"/>ok啦~用法如下： video.setPlayPauseListener(new CustomVideoView.PlayPauseListener() {   public void onPlay() {        System.out.println("video is playing");   }public void onPause() {// TODO Auto-generated method stubSystem.out.println("video is paused");}});
