VideoView播放本地、网络视频及其监听

重写过的VideoView，可以设置宽高和播放、暂停监听

public class MyVideoView extends VideoView {
	  private int mVideoWidth;
	  private int mVideoHeight;
	  private PlayPauseListener mListener;

	  public MyVideoView(Context context) {
	    super(context);
	  }

	  }
	 
	  public MyVideoView(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() {

	        if (mListener != null) {
	            mListener.onPlay();
	        }
	    }

	    interface PlayPauseListener {
	        void onPlay();
	        void onPause();
	    }
	  
	  
	  @Override
	  protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
	    /* The following code is to make videoView view length-width 
	    based on the parameters you set to decide. */
