Notifee 的本地通知在 Android 中不显示

Question

我遇到一个问题，本地通知在 Android 中不显示，但在 IOS 中显示。我已经创建了权限和电池优化检查，看看这是否是问题所在。通知确实会发出声音，并在左上角显示一个小方块，如果我单击并拖动，则会显示本地通知。我现在正在使用模拟器，并且已经在真实设备上尝试过。

这就是我调用通知的方式。

      <Button
         title="Trigger Push Notification"
         size="large"
         onPress={() => onDisplayNotification('default', 'Default Channel', 'Spotback 
         Android', 'Local push notification')}
              />

这是 Notifee 组件。

import notifee, { AndroidStyle, AuthorizationStatus, Notification } from '@notifee/react-native';
import { Alert } from 'react-native';

export const onDisplayNotification = async (id, name, title, body, smallIcon?) => {
  // Request permissions (required for iOS)
  await notifee.requestPermission();

  const settings = await notifee.getNotificationSettings();

  const batteryOptimizationEnabled = await notifee.isBatteryOptimizationEnabled();
  if (batteryOptimizationEnabled) {
    // 2. ask your users to disable the feature
    Alert.alert(
      'Restrictions Detected',
      'To ensure notifications are delivered, please disable battery optimization for the app.',
      [
        // 3. launch intent to navigate the user to the appropriate screen
        {
          text: 'OK, open settings',
          onPress: async () => await notifee.openBatteryOptimizationSettings(),
        },
        {
          text: 'Cancel',
          onPress: () => console.log('Cancel Pressed'),
          style: 'cancel',
        },
      ],
      { cancelable: false }
    );
  }
  if (settings.authorizationStatus == AuthorizationStatus.AUTHORIZED) {
    console.log('Notification permissions has been authorized');
  } else if (settings.authorizationStatus == AuthorizationStatus.DENIED) {
    console.log('Notification permissions has been denied');
  }
  // }

  // Create a channel (required for Android)
  const channelId = await notifee.createChannel({
    id,
    name,
  });

  await notifee.displayNotification({
    title,
    body,
    android: {
      channelId,
      smallIcon,
      pressAction: {
        id,
      },
    },
  });
};

Answer 1

请将您的频道 ID（默认）和频道名称（默认频道）更改为其他内容，例如： id: 自定义频道 名称：自定义频道

Answer 2

尝试像这样创建频道：

const channelId = await notifee.createChannel({
   ...,
   importance: AndroidImportance.HIGH, //Add this line.
});

Answer 3

来自文档：

https://notifee.app/react-native/docs/android/appearance

应用于频道/通知的最高重要性级别。通知将显示在应用程序顶部，允许直接交互，而无需拉下通知栏。此级别仅适用于需要立即关注的紧急通知，例如来电、消息等。

import notifee, { AndroidImportance } from '@notifee/react-native';

const channelId = await notifee.createChannel({
  id: 'important',
  name: 'Important Notifications',
  importance: AndroidImportance.HIGH,
});

await notifee.displayNotification({
  title: 'Your account requires attention',
  body: 'You are overdue payment on one or more of your accounts!',
  android: {
    channelId,
    importance: AndroidImportance.HIGH,
  },
});
