android - 使用android默认闹钟声音列表

我想为Android开发一个警报应用程序，我想使用Android的默认警报声音列表，并让用户在新对话框中从列表中选择警报声音。我可以通过以下代码使用默认警报声音：

Uri alarm = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM);
        MediaPlayer mp = MediaPlayer.create(getApplicationContext(), alarm);
        mp.start();

最佳答案

请尝试这个

public void getRingtones( )
 {
   RingtoneManager ringtoneMgr = new RingtoneManager(this);
   ringtoneMgr.setType(RingtoneManager.TYPE_ALL);
   Cursor alarmsCursor = ringtoneMgr.getCursor();
   int alarmsCount = alarmsCursor.getCount();
   if (alarmsCount == 0 && !alarmsCursor.moveToFirst())
   {
   }
   else
   {
   ringtonesStrings = new String[alarmsCount];
   ringtonesUris = new String[alarmsCount];
   while(!alarmsCursor.isAfterLast() && alarmsCursor.moveToNext()) {
   int currentPosition = alarmsCursor.getPosition();
   rintonesStrings[currentPosition] =  ringtoneMgr.getRingtone(currentPosition).getTitle(getApplicationContext());
  ringtonesUris[currentPosition] =   ringtoneMgr.getRingtoneUri(currentPosition).toString();

  }
//alarmsCursor.close();

 }

}
