Android 获取、设置铃声、音量、静音、扬声器

通过api获取、设置铃声、音量、静音、扬声器其实挺简单的。

[java] view plain

copy

//首先获取一个AudioManager  

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： 

[java] view plain

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：

</pre><pre name="code" class="java"><span style="font-family:Arial, Helvetica, sans-serif;"><span style="white-space: normal;"><span style="font-family:monospace;"><span style="white-space: pre;"></span></span></span></span><pre name="code" class="java">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());  

//别忘了添加权限 
<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS"/>
