    public CustomVideoView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }
    public CustomVideoView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }
    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        //重点。
        int width = getDefaultSize(0, widthMeasureSpec);
        int height = getDefaultSize(0, heightMeasureSpec);
        setMeasuredDimension(width, height);
    }
    @Override
    public void setOnPreparedListener(MediaPlayer.OnPreparedListener l) {
        super.setOnPreparedListener(l);
    }
    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
        return super.onKeyDown(keyCode, event);
    }
}
