android audioManager獲取音量

通過程序獲取android[系統](http://www.2cto.com/os/)手機的鈴聲和音量。同樣，設置鈴聲和音量的方法也很簡單！

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

//通話音量

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

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

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

//系統音量

max = mAudioManager.getStreamMaxVolume( AudioManager.STREAM_SYSTEM ); 

current = mAudioManager.getStreamVolume( AudioManager.STREAM_SYSTEM ); 

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

//鈴聲音量

max = mAudioManager.getStreamMaxVolume( AudioManager.STREAM_RING ); 

current = mAudioManager.getStreamVolume( AudioManager.STREAM_RING ); 

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

//音樂音量

max = mAudioManager.getStreamMaxVolume( AudioManager.STREAM_MUSIC ); 

current = mAudioManager.getStreamVolume( AudioManager.STREAM_MUSIC ); 

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

//提示聲音音量

max = mAudioManager.getStreamMaxVolume( AudioManager.STREAM_ALARM ); 

current = mAudioManager.getStreamVolume( AudioManager.STREAM_ALARM ); 

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