如何知道應用程序是否從Android通知托盤中打開？

Question

如何知道應用程序是否從Android通知托盤中打開？ 例如，我已關閉應用程序（從最近的應用程序列表中清除）。 但我從后端websocket收到通知，我按下它，它打開應用程序。 所以我的問題是，有沒有辦法檢查這是否通知？

查看react-native-push-notification的來源 +接下來的50行（最多為setContentIntent ），您可以在intent中檢查額外的“通知”。

protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        Bundle bundle = getIntent().getBundleExtra("notification");
        if(bundle != null){
            //check if it is the bundle of your notification and do your thing
        }
    }

否則，您可以使用本機模塊方法：

設置傳遞給通知的PendingIntent .setContentIntent()方法指定一個然后在應用程序中恢復的操作。 示例通知：

Intent intent = new Intent(context, MyActivity.class);
intent.setAction("OPEN_MY_APP_FROM_NOTIFICATION");
NotificationCompat.Builder mNotifyBuilder = NotificationCompat.Builder(this, CHANNEL)
            .setContentTitle("Title")
            .setContentIntent(PendingIntent.getActivity(this, REQUEST_CODE, intent, PendingIntent.FLAG_UPDATE_CURRENT))            
mNotificationManager.notify(Notification_REQUEST_CODE,
                                    mNotifyBuilder.build())

在MyActivity.java中

public void onCreate (Bundle savedInstanceState) {
    // Get intent, action and MIME type
    Intent intent = getIntent();
    String action = intent.getAction();
    if(action == "OPEN_MY_APP_FROM_NOTIFICATION"){
         //do whatever you have to do here
    }
}

它很簡單，您可以在推送通知監聽器中收到通知負載

import PushNotification from 'react-native-push-notification'
configurePushNotifications = () => {

    PushNotification.configure({
      // (optional) Called when Token is generated (iOS and Android)
      onRegister: function(token) {
        console.log('PushNotification token', token)
      },

onNotification是您收到本地或遠程通知的地方，當用戶點擊通知托盤時將會調用它

      onNotification: function(notification) {
        console.log('notification received', notification)
      },

      // IOS ONLY (optional): default: all - Permissions to register.
      permissions: {
        alert: true,
        badge: true,
        sound: true,
      },

      // Should the initial notification be popped automatically
      // default: true
      popInitialNotification: true,

      /**
       * (optional) default: true
       * - Specified if permissions (ios) and token (android and ios) will requested or not,
       * - if not, you must call PushNotificationsHandler.requestPermissions() later
       */
      requestPermissions: true,
    })
  }

這就是通知對象的樣子

{
    foreground: false, // BOOLEAN: If the notification was received in foreground or not
    userInteraction: false, // BOOLEAN: If the notification was opened by the user from the notification area or not
    message: 'My Notification Message', // STRING: The notification message
    data: {}, // OBJECT: The push data
}
