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
