有没有一种方法可以在react native中触发reload

请注意,我正在尝试在NativeModules. NotificationModule运行后触发应用程序中的重新加载。下面是我的代码。messaging(). setBackgroundMessageMessage(remoteMessage)=> { if(Platform.OS = 'ios'){ onMessageReceived(remoteMessage)}

if (Platform.OS === 'android') {
    console.log("before modules")
    NativeModules.NotificationModule.triggerFullScreenNotification(remoteMessage.notification.title, remoteMessage.notification.body, 'limestone');
    console.log('Android Message handled in the background');
    console.log(remoteMessage);
    //reload application here
  }
  
});

我不确定react native是否直接等同于从应用程序本身触发完全重新加载。我可能错了。️
但是,您应该能够使用AppState API来检测应用状态的更改(例如,从后台到活动)并相应地触发操作。您可以使用以下解决方案:

import { AppState, Platform, NativeModules, AppRegistry } from 'react-native';

// Add an AppState listener
const handleAppStateChange = (nextAppState) => {
  if (nextAppState === 'active') {
    // Reload the application
    if (Platform.OS === 'android') {
      console.log('Reloading the application...');
      NativeModules.DevSettings.reload(); // This will trigger a reload
    }
  }
};

// Attach the listener when the component mounts
useEffect(() => {
  AppState.addEventListener('change', handleAppStateChange);
  
  // Clean up the listener when the component unmounts
  return () => {
    AppState.removeEventListener('change', handleAppStateChange);
  };
}, []);

// ...

// Inside your existing implementation
if (Platform.OS === 'android') {
  console.log("before modules")
  NativeModules.NotificationModule.triggerFullScreenNotification(remoteMessage.notification.title, remoteMessage.notification.body, 'limestone');
  console.log('Android Message handled in the background');
  console.log(remoteMessage);
}
