问题 I am writing an application which handles the following: Silent - Makes the phone volume silent Low - Makes the phone volume 1 point above the silent Medium - Makes the phone volume medium High - Makes the phone volume maximum Phone volume includes Ringer, video, audio , games volume etc. I know how to achieve Silent mode through AudioManager .
