Android controls the volume size of the phone to toggle the sound mode

(1) Project Introduction

Audiomanager in the Android API, it provides a way to adjust the phone volume.

Audioma.adjustvolume (audiomanager.adjust_lower, 0);

Audioma.adjustvolume (audiomanager.adjust_raise, 0);

can also adjust the phone's sound mode to vibrate or mute

Audioma.setringermode (Audiomanager.ringer_mode_normal);

Audioma.setringermode (audiomanager.ringer_mode_silent);

Audioma.setringermode (audiomanager.ringer_mode_vibrate);
