方法
获取AudioManager
mAudioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);获取最大音量
mAudioManager.getStreamMaxVolume(`streamType`);获取当前音量
mAudioManager.getStreamVolume(`streamType`);设置音量
mAudioManager.setStreamVolume(`streamType`, `音量大小`, `flags`);streamType几种类型- AudioManager.STREAM_MUSIC （媒体音量）
- AudioManager.STREAM_VOICE_CALL （通话音量）
- AudioManager.STREAM_ALARM （闹钟音量）
- AudioManager.STREAM_RING （铃声音量）
- ……
flags几种类型- AudioManager.FLAG_PLAY_SOUND （声音）
- AudioManager.FLAG_SHOW_UI （UI）
- AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE （移除声音和震动）
- ……
