Android 程序獲取、設置鈴聲、音量、靜音、揚聲器

android 程序獲取、設置鈴聲和音量 
通過程序獲取android系統手機的鈴聲和音量。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);
