Android系統鈴聲音量監控(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！

AudioManagermAudioManager = (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

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為鈴聲類型，例如：AudioManager.STREAM_VOICE_CALL、AudioManager.STREAM_SYSTEM等，index為音量大小

falgs為標志位。

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：
設置系統聲音為0就行

//通話時設置靜音

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

//通話時設置免提

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

//別忘了修改的權限

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