问题描述

我想在 React Native 中获取设备静音/增加/减少声音事件的事件.

I would like to get the event of device's mute/increase/decrease sound event in React native.

推荐答案

你可以使用 react-native-system-setting 库来设置音量.

you can use react-native-system-setting library to set the volume.

import SystemSetting from 'react-native-system-setting'

...

SystemSetting.setVolume(0.5);

您还可以获取当前音量:

You can also get the current volume:

SystemSetting.getVolume().then(currentVolume => console.log(currentVolume));

或者听听变化:

useEffect(() => {
    const volumeListener = SystemSetting.addVolumeListener(data => {
        console.log(data.volume);
    });

    return () => SystemSetting.removeVolumeListener(volumeListener)
}, [])
