Android VideoView触发OnPreparedListener对于HLS来说太早

我想在用户等待VideoView开始播放HLS时向他显示一些ProgressDialog。我尝试使用OnPreparedListener来实现这一点，但他会提前触发（在播放器下载m3u8文件后，而不是在视频启动时）

我没有找到另一个合适的listner。。。也许有谁知道这个问题？

谢谢大家。我用下一个黑客解决了我的问题：

videoView.setOnPreparedListener(new OnPreparedListener() {
    public void onPrepared(MediaPlayer mp) {

        final Handler handler = new Handler();
        videoPositionThread = new Runnable() {
             public void run() {
                try {
                    int duration = videoView.getCurrentPosition();
                    if (!(videoPosition == duration && videoView.isPlaying())) {
                        progress.dismiss();
                    }
                    videoPosition = duration;
                    handler.postDelayed(videoPositionThread, 1000);
                } catch (IllegalArgumentException e) {
                    Log.d(TAG, e.getMessage(), e);
                }
            }
        };
        handler.postDelayed(videoPositionThread, 0);
    }
});

我也经历过同样的问题，只是找到了一个适合我需要的解决方案。也许这对你也有用。至少它已经在安卓2.2、2.3和4.2上测试并运行

其想法是定期检查videoView当前位置是否大于零。这是对米哈伊尔答案的修改。也要感谢米哈伊尔：）

去找Handler.PostDelayed（）你能帮我吗？什么是videoPosition？我不知道为什么我的videoview会在超过15秒或20秒的延迟后显示实时视频流。

videoView.setOnPreparedListener(new OnPreparedListener() {
    public void onPrepared(MediaPlayer mp) {

        final Handler handler = new Handler();
        videoPositionThread = new Runnable() {
             public void run() {
                try {
                    int duration = videoView.getCurrentPosition();
                    if (!(videoPosition == duration && videoView.isPlaying())) {
                        progress.dismiss();
                    }
                    videoPosition = duration;
                    handler.postDelayed(videoPositionThread, 1000);
                } catch (IllegalArgumentException e) {
                    Log.d(TAG, e.getMessage(), e);
                }
            }
        };
        handler.postDelayed(videoPositionThread, 0);
    }
});

public class VideoViewActivity extends Activity {

    // Declare variables
    ProgressDialog pDialog;
    VideoView videoview;
    Runnable videoPositionThread;

    // Insert your Video URL
    String VideoURL = "enter your video rtsp url here";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.videoview_main);
        videoview = (VideoView) findViewById(R.id.VideoView);

        pDialog = new ProgressDialog(VideoViewActivity.this);
        pDialog.setTitle("Android Video Streaming Tutorial");
        pDialog.setMessage("Buffering...");
        pDialog.setIndeterminate(false);
        pDialog.setCancelable(true);
        pDialog.show();

        Uri video = Uri.parse(VideoURL);
        videoview.setVideoURI(video);
        videoview.start();

        final Handler handler = new Handler();
        videoPositionThread = new Runnable() {
            public void run() {
                int currentPosition = videoview.getCurrentPosition();

                if (currentPosition > 0)
                    pDialog.dismiss();
                else
                    handler.postDelayed(videoPositionThread, 1000);
            }
        };

        handler.postDelayed(videoPositionThread, 0);
    }
}
