如何在react原生android上显示多行通知？

npm install react-native-push-notification --save

react-native link react-native-push-notification

import com.dieam.reactnativepushnotification.ReactNativePushNotificationPackage;  // 导入React Native Push Notification包

// 在MainActivity类中的getPackages方法中添加以下代码
@Override
protected List<ReactPackage> getPackages() {
  @SuppressWarnings("UnnecessaryLocalVariable")
  List<ReactPackage> packages = new PackageList(this).getPackages();
  packages.add(new ReactNativePushNotificationPackage());  // 添加React Native Push Notification包
  return packages;
}

import PushNotification from 'react-native-push-notification';

class NotificationService {
  configure = () => {
    PushNotification.configure({
      // 配置通知的选项
      // ...
    });
  }

  showNotification = (title, message) => {
    PushNotification.localNotification({
      title: title,
      message: message,
      // 其他通知选项
      // ...
    });
  }
}

export default new NotificationService();

import React, { Component } from 'react';
import { View, Button } from 'react-native';
import NotificationService from './NotificationService';

class MyComponent extends Component {
  handleNotification = () => {
    NotificationService.showNotification('标题', '这是一条多行通知');
  }

  render() {
    return (
      <View>
        <Button title="显示通知" onPress={this.handleNotification} />
      </View>
    );
  }
}

export default MyComponent;
