我用两个videoview显示两个视频，为什么会重叠在一起了

我用两个videoview显示两个视频，为什么会重叠在一起了？如图：

		Uri uri = Uri.parse(Environment.getExternalStorageDirectory().getPath()
				+ "/001.mp4");
		MyVideoView videoView = (MyVideoView) this.findViewById(R.id.videoView1);
		videoView.setVideoURI(uri);
		videoView.start();
		
		MyVideoView videoView2 = (MyVideoView) this.findViewById(R.id.videoView2);
		videoView2.setVideoURI(uri);
		videoView2.start();

public class MyVideoView extends VideoView {

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

	public MyVideoView(Context context, AttributeSet attrs, int defStyle) {
		super(context, attrs, defStyle);
	}

	public MyVideoView(Context context, AttributeSet attrs) {
		super(context, attrs);
	}

	@Override
	protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
		int width = 700;
		int height = 400;
        setMeasuredDimension(width, height);
	}

}
