添加视频后如何获取视频的宽度和高度

Question

视频的布局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>

当我获得视频视图的高度和宽度时，它会给我match_parent的宽度和高度，但不会在视频中播放视频的宽高比宽度和高度（无论视频中的视频覆盖的宽度和高度如何）。

在这里，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videoview中播放视频的黑色区域的宽度和高度。 但videoview的getWidth（）或getMeasuredWidth（）和getHeight（）或getMeasuredHeight（）给了我match_parent的宽度和高度。

所以，如何获得视频区域的宽度和高度（只有我们在图片中看不到整个宽度的黑暗区域）。

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);
        }
    });
