另一件事是seekBar的计时器，它在音频文件的持续时间内问题是音频文件做（迷你）每1秒停止一次如何让搜索栏每秒更新一次而不做任何停止< / p>

        seekBar2.setMax(mediaPlayer.getDuration());
        seekBar2.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {

        @Override
        public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
            mediaPlayer.seekTo(progress);

        }

        @Override
        public void onStartTrackingTouch(SeekBar seekBar) {

        }

        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {

        }
    });

        new Timer().scheduleAtFixedRate(new TimerTask() {
        @Override

        public void run() {
            seekBar2.setProgress(mediaPlayer.getCurrentPosition());
        }
    },0,1000);
    public void reset(View v) {
        mediaPlayer.reset();
    }

尝试此操作以重置您的mediaPlayer

public void reset(View v) {
       mediaPlayer.seekTo(0);
       mediaPlayer.start();
}

尝试此操作以更新搜索栏

    private Handler mHandler = new Handler();
//you have to  update Seekbar on UI thread
Your.Activity.this.runOnUiThread(new Runnable() {

    @Override
    public void run() {
        if(mediaPlayer != null){
            int mCurrentPosition = mediaPlayer.getCurrentPosition() / 1000;
            seekBar2.setProgress(mCurrentPosition);
        }
        mHandler.postDelayed(this, 1000);
    }
});

当用户拖动MediaPlayer使用以下代码时，您需要更新SeekBar的位置

seekBar2.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {

        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {

        }

        @Override
        public void onStartTrackingTouch(SeekBar seekBar) {

        }

            @Override
            public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {                
                if(mediaPlayer != null && fromUser){
                    mediaPlayer.seekTo(progress * 1000);
                }
            }
    });

单击时如何使重置按钮自动再次播放？
