我注意到在Android默认的语音记录器，可以感知的音量是你的声音和的显示它给你的UI参数。

i notice in the Android Default Voice Recorder that can sense how loud is your voice and show it to you in UI parameter .

我可以使用这起故意或者我怎么可以设定一个code表示感觉到Android的声音的响度。

Can i use this from the intent or how can i program a code that sense the loudness of the voice in Android.
