23、铃声设置

Android系统的铃声

Android本身提供了一些默认的铃声文件，这些文件都放在“/system/media/audio”目录中。如果是我们自己下载的铃声文件（一般为mp3音频文件），可以放在SD卡的music目录。铃声主要有3种：一般的铃声（如来电铃声）、闹钟铃声和通知铃声。这3种铃声要分别放在如下的目录。

/sdcard/music/ringtones：一般的铃声，如来电铃声。

/sdcard/music/alarms：闹钟铃声。

/sdcard/music/notifications：警告或通知铃声。

调用铃声设置窗口

RingtoneManager.TYPE_RINGTONE：设置来电铃声

RingtoneManager.TYPE_ALARM：设置闹钟铃声

RingtoneManager.TYPE_NOTIFICATION：设置通知铃声
