1. 首先在xml文件中定义SeekBar和TextView控件：

2. 在java代码中初始化SeekBar和TextView：

SeekBar seekBar = findViewById(R.id.seekbar); TextView currentTime = findViewById(R.id.current_time);

3. 在MediaPlayer的onPrepared()方法中添加如下代码：

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

@Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
    if(fromUser) {
        mediaPlayer.seekTo(progress);
        currentTime.setText(formatTime(mediaPlayer.getCurrentPosition()));
    }
}

@Override
public void onStartTrackingTouch(SeekBar seekBar) {}

@Override
public void onStopTrackingTouch(SeekBar seekBar) {}

});

4. 添加一个方法用于格式化时间：

private String formatTime(int millis) { String output = "00:00"; long seconds = millis / 1000; long minutes = seconds / 60; seconds = seconds % 60; if (minutes < 10) { output = "0" + minutes + ":"; } else { output = minutes + ":"; } if (seconds < 10) { output += "0"; } output += seconds; return output; }

这样就能正确显示进度条和当前时间了。
