Android 程式擷取、設定鈴聲和音量 
通過程式擷取android系統手機的鈴聲和音量。同樣，設定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); 

設定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為標誌位。  設定震動：
mVibrator = (Vibrator) mContext.getSystemService(Service.VIBRATOR_SERVICE);   
                long[] pattern = {150, 100}; // OFF/ON/OFF/ON...  
                mVibrator.vibrate(pattern, -1);靜音：
設定系統聲音為0就行 //通話時設定靜音System.out.println("isMicrophoneMute =" + audioManager.isMicrophoneMute());
    audioManager.setMicrophoneMute(!audioManager.isMicrophoneMute()); //通話時設定免提

System.out.println("isSpeakerphoneOn =" + audioManager.isSpeakerphoneOn());
    audioManager.setSpeakerphoneOn(!audioManager.isSpeakerphoneOn());//別忘了修改的許可權 <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS"/>
