React Native保持scree清醒

Question

我找到了一个模块react-native-keep-awake，用于让屏幕保持清醒状态以便做出反应。但是，看起来像这个模块有一些问题，我尝试console.log(this.props.screenShouldBeAwake);值，它给了我undefined。有没有其他方法可以触发屏幕醒来？

Answer 1

好的我有解决方案，希望将来帮助别人。

1. 从'react-native-keep-awake'导入KeepAwake;
2. 创建一个州并将其命名为keepawake，或任何你想要的名称。

3. 创建一个箭头函数，以便在onPress

   时调用

   changeKeepAwake = () =>{
      if(!this.state.keepawake){
        this.state.keepawake = true;
        KeepAwake.activate();
      }else{
        this.state.keepawake = false;
        KeepAwake.deactivate();
      }
   

   }

4. DONE

Answer 2

现在，expo支持此功能。易于使用。

import { activateKeepAwake, deactivateKeepAwake } from 'expo-keep-awake';
// Prevents the screen from sleeping until deactivateKeepAwake is called with the same tag value.
activateKeepAwake("tag");
// Releases the lock on screen-sleep prevention associated with the given tag value. 
deactivateKeepAwake("tag");
