android - VideoView 为 HLS 过早触发 OnPreparedListener

Question

我想在用户等待 VideoView 开始播放 HLS 时向他展示一些 ProgressDialog。我尝试为此使用 OnPreparedListener，但他提前触发(播放器下载 m3u8 文件后，而不是视频开始时)。

VideoView player = (VideoView) findViewById(R.id.player);
String httpLiveUrl = "http://example.com/playlist.m3u8";

player.setVideoURI(Uri.parse(httpLiveUrl));
player.setMediaController(new MediaController(this));
player.requestFocus();

player.setOnPreparedListener(new OnPreparedListener() {
public void onPrepared(MediaPlayer mp) {
    progress.dismiss();
}
});

progress.show();
player.start();

我没有找到另一个合适的监听器...可能有人知道 sloution 吗？

感谢大家。我用下一个 hack 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);
    }
});
