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！

設置音量的方法也很簡單，AudioManager提供了方法：

public voidsetStreamVolume(intstreamType,intindex,intflags)

其中streamType有內置的常量，去文檔里面就可以看到。

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);
