获取android系统手机的铃声和音量  

通过程序 获取android系统手机的铃声和音量。设置音量的方法也很简单，AudioManager提供了方法：

publicvoidsetStreamVolume(intstreamType,intIndex,intFlags)其中streamType有内置的常量，去文档里面就可以看到。　　

Java代码：

AudioManager audioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);

//通话音量

int max = audioManager.getStreamMaxVolume( AudioManager.STREAM_VOICE_CALL );

int current = audioManager.getStreamVolume( AudioManager.STREAM_VOICE_CALL ); 

//系统音量

max = audioManager.getStreamMaxVolume( AudioManager.STREAM_SYSTEM );

current = audioManager.getStreamVolume( AudioManager.STREAM_SYSTEM );

//铃声音量

max = audioManager.getStreamMaxVolume( AudioManager.STREAM_RING );

current = audioManager.getStreamVolume( AudioManager.STREAM_RING ); 

//音乐音量

max = audioManager.getStreamMaxVolume( AudioManager.STREAM_MUSIC );

current =audioManager.getStreamVolume( AudioManager.STREAM_MUSIC );

//提示声音音量

max = audioManager.getStreamMaxVolume( AudioManager.STREAM_ALARM );

current = audioManager.getStreamVolume( AudioManager.STREAM_ALARM );
