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)
其中 streamType 有內置的常量，去文檔里面就可以看到
