Question

我正在使用视频播放器并希望在启动之前显示加载程序。以下是我的代码段。任何人都可以帮我解决这个问题吗？

            showpDialog();
             String ALLOWED_URI_CHARS = "@#&=*+-_.,:!?()/~'%";
            String urlEncoded = Uri.encode(vid_path, ALLOWED_URI_CHARS);
            System.out.println(urlEncoded);
            final VideoView videoView =(VideoView) findViewById(R.id.vv);
            videoView.setVideoPath(rlEncoded);
            MediaController mediaController = new
            MediaController(this);
            mediaController.setAnchorView(videoView);
            videoView.setMediaController(mediaController);    
            videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener()  {
            @Override
           public void onPrepared(MediaPlayer mp) {
          Log.i("", "Duration = " +videoView.getDuration());
        }
    });

 hidepDialog();
 videoView.start();

然后，在onCreate()中，在致电runOnUiThread之前，启动dialog

progressDialog = ProgressDialog.show(this, "", "Loading...", true);

设置OnPreparedListener()，当视频准备好播放时，dialog会关闭mVideoView.setOnPreparedListener(new OnPreparedListener() { public void onPrepared(MediaPlayer arg0) { progressDialog.dismiss(); mVideoView.start(); } });
