Android MediaPlayer.getCurrentPosition() 返回 0

Question

       Runnable updateSeekbar=new Runnable() {
        @Override
        public void run() {
            try{
                while (true) {
                    if (!isPlayerDead) {
                        Log.d("Threads", "Thread is running successfully.");
                        int progress=mediaPlayer.getCurrentPosition();
                        seekBar.setProgress(progress);
                        Log.d("Seekbar",seekBar.getProgress()+"");
                        Log.d("MediaProgress",mediaPlayer.getCurrentPosition()+"");
                        String s=modifyTime(mediaPlayer.getCurrentPosition() / 1000 / 60) + ":" + modifyTime((mediaPlayer.getCurrentPosition() / 1000) % 60);
                        progressTime.setText(s);

                    }
                }
            }
            catch (Exception e){
                e.printStackTrace();
            }
        }
    };
    Executor executor=new Executor() {
        @Override
        public void execute(Runnable command) {
            Thread thread=new Thread(command);
            thread.start();
        }
    };
executor.execute(updateSeekbar);

我正在制作一个媒体播放器来播放音频，但是当我尝试使用 mediaplayer.getCurrentPosition 更新搜索栏时，它总是返回 0。

如何获取媒体播放器的当前位置？强文本

在你的 while 循环中添加这个：

videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
    @Override
    public void onPrepared(MediaPlayer mp) {
        duration = mp.getCurrentPosition();
         seekBar.setProgress(progress);
         Log.d("Seekbar",seekBar.getProgress()+"");
    }
});
