在本地和url路徑中播放視頻時的問題

Question

我在VideoView中播放視頻

從SD卡播放時，它會在全屏幕中顯示正確的寬度和高度。當我嘗試從服務器播放時，視頻寬度變小，視頻重新調整大小。

如何以原始尺寸和全屏播放視頻？

看看的documentation並實現類似下面的代碼的onPrepared方法：

//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); 
}
