Android 程序获取、设置铃声和音量  
通过程序获取android系统手机的铃声和音量。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);  
  
设置音量的方法也很简单，AudioManager提供了方法：  
public void setStreamVolume(int streamType, int index, int flags)  
streamType为铃声类型，例如：AudioManager.STREAM\_VOICE\_CALL、AudioManager.STREAM\_SYSTEM等，index为音量大小  
falgs为标志位。  
  
设置振动：  
mVibrator = (Vibrator) mContext.getSystemService(Service.VIBRATOR\_SERVICE);  
long\[\] pattern = \{150, 100\}; // OFF/ON/OFF/ON...  
mVibrator.vibrate(pattern, -1);  
静音：  
设置系统声音为0就行  
  
//通话时设置静音  
System.out.println("isMicrophoneMute =" + audioManager.isMicrophoneMute());  
audioManager.setMicrophoneMute(!audioManager.isMicrophoneMute());  
  
//通话时设置免提  
System.out.println("isSpeakerphoneOn =" + audioManager.isSpeakerphoneOn());  
audioManager.setSpeakerphoneOn(!audioManager.isSpeakerphoneOn());  
//别忘了修改的权限
