英文:
Why isn't the class that I define correctly reading in android studio and showing errors?
问题
我创建了一个 Android 应用程序，这一点上在使用 DataBinding 时出现了错误，但在运行过程中它正常工作。
我曾经通过在 Build 菜单中点击 Rebuild Project，同时选择 Clean Project 来解决这个问题，但现在这种方式已经没有效果了。
但是现在它在我之前创建的 Model Class 中的 getter 方法上给我报错，如下图所示。
> 注意：类 FCM 中我正在创建一个静态方法 sendNotificationToTopic()，我在所有项目中都遇到了这个问题。
这是导入的代码：
import androidx.annotation.NonNull;
import androidx.appcompat.app.AlertDialog;
import androidx.appcompat.app.AppCompatActivity;
import androidx.databinding.DataBindingUtil;
import androidx.recyclerview.widget.LinearLayoutManager;
import android.annotation.SuppressLint;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import com.google.firebase.firestore.CollectionReference;
import com.google.firebase.firestore.FirebaseFirestore;
import com.google.gson.Gson;
import com.madeveloper.kayilarcarpetadmin.R;
import com.madeveloper.kayilarcarpetadmin.adapter.DescriptionOrderAdapter;
import com.madeveloper.kayilarcarpetadmin.databinding.ActivityDescriptionOrderBinding;
import com.madeveloper.kayilarcarpetadmin.model.CartItem;
import com.madeveloper.kayilarcarpetadmin.model.Order;
import com.madeveloper.kayilarcarpetadmin.model.Product;
import com.madeveloper.kayilarcarpetadmin.util.Constant;
import com.madeveloper.kayilarcarpetadmin.util.Util;
import com.madeveloper.kayilarcarpetadmin.util.FCM;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
非常感谢提前的帮助。

I created an Android application and at this point I was getting errors on using DataBinding but in the Run process it is working properly .
I was solving this problem by clicking on Rebuild Project from the Build menu and also choosing Clean Project and now it has no benefit this way.
But now it gives me errors on the Model Class on the Method getter that I created before as shown in the picture below.

This imports code :
