android:videoView

網上代碼大都類似：

private static ProgressDialog progressDialog;public String video_url;private  MediaController mediaController;@Overrideprotected void onCreate(Bundle savedInstanceState) {    // TODO Auto-generated method stub    super.onCreate(savedInstanceState);    setContentView(R.layout.videoalbum);    progressDialog = ProgressDialog.show(ShowVideo.this, "", "Buffering video...", true);    getWindow().setFormat(PixelFormat.TRANSLUCENT);     video_url = "http://www.letumobi.com/videouploads/cd0a4170-1fb2-4fba-b17c-b5d70b2cd2e7.mp4";        try {                final VideoView videoView =(VideoView)findViewById(R.id.video_viewId);                mediaController = new MediaController(ShowVideo.this);                mediaController.setAnchorView(videoView);                // Set video link (mp4 format )                Uri video = Uri.parse(video_url);                videoView.setMediaController(mediaController);                videoView.setVideoURI(video);                videoView.setOnPreparedListener(new OnPreparedListener() {                    public void onPrepared(MediaPlayer mp) {                        progressDialog.dismiss();                       videoView.start();                    }                });             }catch(Exception e){                  progressDialog.dismiss();                 System.out.println("Video Play Error :"+e.getMessage());             }    }

但是在模擬器上跑只有聲音沒有映像，真機上則沒有問題。
