使用react-native-push-notification
//创建通道

import PushNotification, {Importance} from 'react-native-push-notification';
...
  PushNotification.createChannel(
    {
      channelId: "channel-id", // (required)
      channelName: "My channel", // (required)
      channelDescription: "A channel to categorise your notifications", // (optional) default: undefined.
      playSound: false, // (optional) default: true
      soundName: "default", // (optional) See `soundName` parameter of `localNotification` function
      importance: Importance.HIGH, // (optional) default: Importance.HIGH. Int value of the Android notification importance
      vibrate: true, // (optional) default: true. Creates the default vibration pattern if true.
    },
    (created) => console.log(`createChannel returned '${created}'`) // (optional) callback returns whether the channel was created, false means it already existed.
  );

//这会将每个新通知显示一段时间，然后将其推入组

PushNotification.localNotification({
      channelId: 'channel-id',
      title: `New message`,
      message: 'Hello world',
})

//此群组消息

PushNotification.localNotification({
      channelId: 'channel-id',
      id: 'messages',
      group: 'messages',
      groupSummary: true
})
