通过程序获取android系统手机的铃声和音量

It is simple!

AudioManager mAudioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);

//通话音量

int max = mAudioManager.getStreamMaxVolume( AudioManager.STREAM_VOICE_CALL );

int current = mAudioManager.getStreamVolume( AudioManager.STREAM_VOICE_CALL );

Log.d(”VIOCE_CALL”, “max : ” + max + ” current : ” + current);

//系统音量

max = mAudioManager.getStreamMaxVolume( AudioManager.STREAM_SYSTEM );

current = mAudioManager.getStreamVolume( AudioManager.STREAM_SYSTEM );

Log.d(”SYSTEM”, “max : ” + max + ” current : ” + current);

//铃声音量

max = mAudioManager.getStreamMaxVolume( AudioManager.STREAM_RING );

current = mAudioManager.getStreamVolume( AudioManager.STREAM_RING );

Log.d(”RING”, “max : ” + max + ” current : ” + current);

//音乐音量

max = mAudioManager.getStreamMaxVolume( AudioManager.STREAM_MUSIC );

current = mAudioManager.getStreamVolume( AudioManager.STREAM_MUSIC );

Log.d(”MUSIC”, “max : ” + max + ” current : ” + current);

//提示声音音量

max = mAudioManager.getStreamMaxVolume( AudioManager.STREAM_ALARM );

current = mAudioManager.getStreamVolume( AudioManager.STREAM_ALARM );

Log.d(”ALARM”, “max : ” + max + ” current : ” + current);

设置音量的方法也很简单，AudioManager提供了方法：
public void setStreamVolume(int streamType, int index, int flags)
