SurfaceView高度+宽度被忽略

以下脚本工作完美无瑕，但在将我的表面视图从纵向更改为横向后，我的视频播放器的大小将会变为f'd。尝试了几个选项，如setFixedSize(),setSizeFromLayout()，并从我的表面视图中删除所有涉及我的宽度+高度的选项。有谁知道下面的代码有什么问题吗？还是有人在过去有同样的问题？SurfaceView高度+宽度被忽略

我需要回答：'（ – Jordy

同样的问题在这里：

我相信问题是Vitamio库，因为我与Vitamio SDK打交道时都遇到了类似的问题。当使用SurfaceView并调用setLayoutParams(ViewGroup.LayoutParams params)时，调整大小对我无效。下面的代码使用标准的Android媒体框架可以正常工作，但是导入vitamio包会打破它。

 
RelativeLayout.LayoutParams video_VIEWLAYOUT = (RelativeLayout.LayoutParams) videoView.getLayoutParams(); 
video_VIEWLAYOUT.width = screenWidth; 
video_VIEWLAYOUT.height = (int) (((float)videoHeight/(float)videoWidth) *(float)screenWidth); 
videoView.setLayoutParams(video_VIEWLAYOUT);

我的建议是使用io.vov.vitamio.widget.VideoView代替android.view.SurfaceView的尝试。

使用这种方法，并调用它里面onConfigurationChanged方法：

private void setVideoSize() { 

    // // Get the dimensions of the video 

      // mVideoView is your video view object. 

    int videoWidth = mVideoView.getVideoWidth(); 
    int videoHeight = mVideoView.getVideoHeight(); 
    float videoProportion = (float) videoWidth/(float) videoHeight; 

    // Get the width of the screen 
    int screenWidth = getWindowManager().getDefaultDisplay().getWidth(); 
    int screenHeight = getWindowManager().getDefaultDisplay().getHeight(); 
    float screenProportion = (float) screenWidth/(float) screenHeight; 

    // Get the SurfaceView layout parameters 
    android.view.ViewGroup.LayoutParams lp = mVideoView.getLayoutParams(); 
    if (videoProportion > screenProportion) { 
     lp.width = screenWidth; 
     lp.height = (int) ((float) screenWidth/videoProportion); 
    } else { 
     lp.width = (int) (videoProportion * (float) screenHeight); 
     lp.height = screenHeight; 
    } 
    // Commit the layout parameters 
    mVideoView.setLayoutParams(lp); 
}

现在对方向的改变，你的videoview将被调整。
