React-native-firebase后台通知(Android)

Question

我正在使用react- native -firebase库，当它们在后台时，我正在集思广益地定制我的通知，我试图按照文档操作，但没有用，有没有本机代码.java来处理通知？

要自定义后台通知，可以将其添加到应用程序的索引中：

​

import { AppRegistry } from 'react-native'
import App from './App'
import { backgroundMessageNotificationHandler } from 'src/common/notifications'

AppRegistry.registerComponent('testApp', () => App)
AppRegistry.registerHeadlessTask(
  'RNFirebaseBackgroundMessage',
  () => backgroundMessageNotificationHandler)

​

backgroundMessageNotificationHandler可能是这样的：

​

export const backgroundMessageNotificationHandler = async (message: any) => {
  const localNotification = new firebase.notifications.Notification().android
    .setChannelId(androidNotificationsChannel.channelId)
    .android.setSmallIcon('iconBlackAndWhite')
    .android.setLargeIcon('iconBlackAndWhite')
    .android.setPriority(firebase.notifications.Android.Priority.High)
    .setNotificationId(message.messageId)
    .setSound('default')
    .setTitle(message.data.title)
    .setBody(message.data.body)
    .setData(message.data)

  if (Platform.OS === 'android') {
    createChannel()
  }

  firebase.notifications().displayNotification(localNotification)

  return Promise.resolve()
}
