如何获取活动中包含的VideoView的高度 [英] How to get the Height of the VideoView included in the Activity

问题描述

我需要获取我在android中活动的VideoView的高度，我正在使用以下命令，但它的高度为0.

I need to get the Height of the VideoView of my activity in android, I am using the following commands, but it gives me the Height as 0.

VideoView vv = (VideoView)findViewById(R.id.video1);
String surl="SOME_LINK.mp4";
        Uri uri=Uri.parse(surl);
        MediaController mc = new MediaController(this);
        vv.setVideoURI(uri);
        vv.setMediaController(mc);
        mc.setMediaPlayer(vv);
        mc.setAnchorView(vv);
        int vvHeight=vv.getMeasuredHeight();
        Log.d("VideoView Height:",vvHeight+""); // The Logcat output : 0.
        int VVheight=vv.getHeight();
        Log.d("The Height of VideoView is :",VVheight+""); // The Logcat output : 0

有人可以告诉我我犯了什么错误吗?

Can Someone tell me what I am making an mistake.

推荐答案

您正在尝试在绘制视图之前获取宽度/高度.

You are trying to get width/height before the view has been drawn.

尝试一下:

vv.post(new Runnable() { 
@Override
  public void run() {
    // get height and width here
  }
});

view.post(Runnable)导致将可运行对象添加到消息队列中.可运行对象将在UI线程上运行.

view.post(Runnable) causes the runnable to be added to the message queue. The runnable will run on the UI thread.
