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
