android - 在本地和 url 路径中播放视频时出现问题

Question

我在 VideoView 中播放视频

当我从 SD 卡播放时，它全屏显示正确的宽度和高度。当我尝试从服务器播放时，视频宽度更小并且视频被重新调整大小。

如何以原始尺寸和全屏播放视频？

查看文档并实现 onPrepared 方法，如以下代码：

//prepare the video
public void onPrepared(MediaPlayer mp) {        
    progressBarWait.setVisibility(View.GONE);

    //First get the size of the video
    int videoWidth = player.getVideoWidth();
    int videoHeight = player.getVideoHeight();
    float videoProportion = (float) videoWidth / (float) videoHeight;  

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

    //Adjust
    LayoutParams lp = surfaceViewFrame.getLayoutParams();
    if (videoProportion > screenProportion) {
        lp.width = screenWidth;
        lp.height = (int) ((float) screenWidth / videoProportion);
    } else {
        lp.width = (int) (videoProportion * (float) screenHeight);
        lp.height = screenHeight;
    }
    surfaceViewFrame.setLayoutParams(lp);

    if (!player.isPlaying()) {
        player.start();         
    }
    surfaceViewFrame.setClickable(true);
}
