Android怎么判断设备是否静音

Question

我在开发一款应用，需要播放声音和用户交互，但是很多时候用户的手机是静音状态的。
Android有没有接口，可以判断他现在是不是处在静音状态，然后我可以弹出一个提示
他点击一个按钮，就把声音开启

Answer 1

Mute means the volume is 0. Use AudioManager to get the current volume and determine whether it is 0.

But there are many types of volume in the Android system: STREAM_VOICE_CALL, STREAM_SYSTEM, STREAM_RING, STREAM_MUSIC, STREAM_ALARM

I think all you need is to check the media volume STREAM_MUSIC
