如何让MediaPlayer实现AB段复读功能
近日在做一个学习法语的小应用，被MP3AB段复读的功能困扰了很久，最后终于在网上找到一个解决方法，就是使用CountDownTimer让MediaPlayer只播放MP3的某个区段，轻松解决了AB段复读的功能。详细代码如下：
public void play(final String filePath) throws Exception {try {if (mMediaPlayer == null) {// 创建MediaPlayer对象并设置ListenermMediaPlayer = new MediaPlayer();} else {// 复用MediaPlayer对象mMediaPlayer.reset();}mMediaPlayer.setDataSource(filePath);mMediaPlayer.prepare();mMediaPlayer.setVolume(10.f, 1.0f);// 复读第10秒到第20秒这个区间的音频int startPos = 10000;int endPos = 20000;// Try to play three timesrepeatAToB(startPos, endPos, 3);} catch (Exception e) {e.printStackTrace();}}private void repeatAToB(final int startPos, final int endPos, final int repeatTimes)throws Exception {mMediaPlayer.seekTo(startPos);mMediaPlayer.start();CountDownTimer cntr_aCounter = new CountDownTimer(/* millisInFuture= */endPos - startPos, /* countDownInterval= */1000) {public void onTick(long millisUntilFinished) {// DO SOMETHING}public void onFinish() {// Code fire after finishif((repeatTimes - 1) > 0){try {repeatAToB(startPos, endPos, repeatTimes - 1);} catch (Exception e) {e.printStackTrace();}}else{mMediaPlayer.stop();}}};cntr_aCounter.start();}
