我的按钮有问题。我有31个不同的mp3文件。我添加了31个按钮。当我按下第29个按钮时30和31不能在我的手机中工作。模拟器工作正常。我还有一个问题，当我进入主动，然后再次加入我的mp3页面时，有时候并没有按下所有按钮。

您可以查看Media Player docs
这个想法是，你不需要创建你的玩家。只使用一个媒体播放器，但在使用下一个数据之前发布以前的数据：
+------------+---------+----------+
| DateField | StringA | StringB |
+------------+---------+----------+
| 01/01/2015 | xxx | abc123 |
| 02/01/2015 | zzz | abc12345 |
| 03/01/2015 | xxx | abc |
+------------+---------+----------+
您的代码：
if (mplayer !=null) {
mplayer.stop();
mplayer.release();
mplayer = null;
}
mplayer = new MediaPlayer();
mplayer.setDataSource(getApplicationContext(),
Uri.parse(CONSTANTS.RES_PREFIX + R.raw.id));
mplayer.prepare();
mplayer.start();
}
看看onClick。您需要为每个按钮创建路径并将其发送到startNewVoice方法。不要忘记批准它是否为你工作
