android - 添加视频后如何获取videoview的宽高

Question

videoview布局xml:

   <RelativeLayout
        android:id="@+id/videoEditorParent"
        android:layout_width="match_parent"
        android:layout_height="400dp">

        <RelativeLayout
            android:id="@+id/vidEditorWrapper"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"
            android:background="@color/colorAccent">

            <VideoView
                android:id="@+id/vidEditor"
                android:layout_width="match_parent"
                android:layout_height="match_parent" />

        </RelativeLayout>

    </RelativeLayout>

当我获得视频 View 的高度和宽度时，它会给我 match_parent 的宽度和高度，但不是视频 View 中正在播放的视频的宽高比宽度和高度(视频在视频 View 中覆盖的任何宽度和高度)。

这里是我的代码:

            viewWidth = vidEditor.getWidth();
            viewHeight = vidEditor.getHeight();

            ViewGroup.LayoutParams layoutParams = vidEditorWrapper.getLayoutParams();

            dpWidthView = utilities.pxToDp(viewWidth);
            dpHeightView = utilities.pxToDp(viewHeight);

            dpWidthViewPerVal = (dpWidthView * 2) / 100;

            layoutParams.width = viewWidth;
            layoutParams.height = viewHeight;
            vidEditorWrapper.setLayoutParams(layoutParams);

我的屏幕截图:

我想要在视频 View 中播放视频的黑色区域的宽度和高度。但是 videoview 的 getWidth() 或 getMeasuredWidth() 和 getHeight() 或 getMeasuredHeight() 给了我 match_parent 宽度和高度。

那么，我怎样才能得到视频区域的宽度和高度(只有我们在图片中可以看到的暗区，而不是全宽)覆盖在视频 View 中。

尝试在 OnPreparedListener 中应用您的代码例如:

    videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {

        @Override
        public void onPrepared(MediaPlayer mp) {
            viewWidth = vidEditor.getWidth();
            viewHeight = vidEditor.getHeight();

            ViewGroup.LayoutParams layoutParams = 
            vidEditorWrapper.getLayoutParams();

            dpWidthView = utilities.pxToDp(viewWidth);
            dpHeightView = utilities.pxToDp(viewHeight);

            dpWidthViewPerVal = (dpWidthView * 2) / 100;

            layoutParams.width = viewWidth;
            layoutParams.height = viewHeight;
            vidEditorWrapper.setLayoutParams(layoutParams);
        }
    });
