android audioManager获取音量

通过程序获取android[系统](http://www.2cto.com/os/)手机的铃声和音量。同样，设置铃声和音量的方法也很简单！

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

//通话音量

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

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

Log.d(“VIOCE_CALL”, “max : ” + max + ” current : ” + current); 

//系统音量

max = mAudioManager.getStreamMaxVolume( AudioManager.STREAM_SYSTEM ); 

current = mAudioManager.getStreamVolume( AudioManager.STREAM_SYSTEM ); 

Log.d(“SYSTEM”, “max : ” + max + ” current : ” + current); 

//铃声音量

max = mAudioManager.getStreamMaxVolume( AudioManager.STREAM_RING ); 

current = mAudioManager.getStreamVolume( AudioManager.STREAM_RING ); 

Log.d(“RING”, “max : ” + max + ” current : ” + current); 

//音乐音量

max = mAudioManager.getStreamMaxVolume( AudioManager.STREAM_MUSIC ); 

current = mAudioManager.getStreamVolume( AudioManager.STREAM_MUSIC ); 

Log.d(“MUSIC”, “max : ” + max + ” current : ” + current); 

//提示声音音量

max = mAudioManager.getStreamMaxVolume( AudioManager.STREAM_ALARM ); 

current = mAudioManager.getStreamVolume( AudioManager.STREAM_ALARM ); 

Log.d(“ALARM”, “max : ” + max + ” current : ” + current);
