Android 程序獲取設置代碼

       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！

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