通過程式擷取android系統手機的鈴聲和音量

It is simple!

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)
