Android 程序獲取、設置鈴聲、音量、靜音、揚聲器

Android 程序獲取、設置鈴聲和音量 
通過程序獲取android系統手機的鈴聲和音量。同樣，設置鈴聲和音量的方法也很簡單！ 

AudioManager mAudioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE); 
//通話音量 

int max = mAudioManager.getStreamMaxVolume( AudioManager.STREAM_VOICE_CALL ); 
int current = mAudioManager.getStreamVolume( AudioManager.STREAM_VOICE_CALL ); 
Log.d(”VIOCE_CALL”, “max : ” + max + ” current : ” + current); 
//系統音量 

max = mAudioManager.getStreamMaxVolume( AudioManager.STREAM_SYSTEM ); 
current = mAudioManager.getStreamVolume( AudioManager.STREAM_SYSTEM ); 
Log.d(”SYSTEM”, “max : ” + max + ” current : ” + current); 
//鈴聲音量 

max = mAudioManager.getStreamMaxVolume( AudioManager.STREAM_RING ); 
current = mAudioManager.getStreamVolume( AudioManager.STREAM_RING ); 
Log.d(”RING”, “max : ” + max + ” current : ” + current); 
//音樂音量 

max = mAudioManager.getStreamMaxVolume( AudioManager.STREAM_MUSIC ); 
current = mAudioManager.getStreamVolume( AudioManager.STREAM_MUSIC ); 
Log.d(”MUSIC”, “max : ” + max + ” current : ” + current); 
//提示聲音音量 

max = mAudioManager.getStreamMaxVolume( AudioManager.STREAM_ALARM ); 
current = mAudioManager.getStreamVolume( AudioManager.STREAM_ALARM ); 
Log.d(”ALARM”, “max : ” + max + ” current : ” + current); 

設置音量的方法也很簡單，AudioManager提供了方法： 
public void setStreamVolume(int streamType, int index, int flags) 

streamType爲鈴聲類型，例如：AudioManager.STREAM_VOICE_CALL、AudioManager.STREAM_SYSTEM等，index爲音量大小

falgs爲標誌位。

 

 

設置振動：
mVibrator = (Vibrator) mContext.getSystemService(Service.VIBRATOR_SERVICE);   
                long[] pattern = {150, 100}; // OFF/ON/OFF/ON...  
                mVibrator.vibrate(pattern, -1);

靜音：
設置系統聲音爲0就行

 

//通話時設置靜音 ,  關閉手機話筒 

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

 

//通話時設置免提   打開手機揚聲器

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