Android 程序获取、设置铃声、音量、静音、扬声器

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 ,  关闭手机话筒 

System.out.println("isMicrophoneMute =" + audioManager.isMicrophoneMute());
    audioManager.setMicrophoneMute(!audioManager.isMicrophoneMute());

 

//通话时设置免提   打开手机扬声器

System.out.println("isSpeakerphoneOn =" + audioManager.isSpeakerphoneOn());
    audioManager.setSpeakerphoneOn(!audioManager.isSpeakerphoneOn());
