使用android studio的FirebaseRecyclerAdapter适配器无法将字符串转换为对象

当我使用FirebaseRecyclerAdapter类时，会出现以下错误： 添加这两行代码后，无法将java.lang.String类型的对象转换为com.photoblog.kyrillos.blog.Model.Users类型，它会崩溃 recyclerView.setHasFixedSize（true）； recyclerView.setLayoutManager（linearLayoutManager）

我的代码是

import android.content.Intent;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

        recyclerView.setAdapter(adapter);
    }

对不起，伙计们，我找到了错误的确切位置。 而是这一行

mDatabase = FirebaseDatabase.getInstance().getReference().child("Users").child(mAuth.getCurrentUser().getUid());

我应该写这个

无论如何，感谢您。您在哪一行出现此错误？它没有给我唯一的行，无法将java.lang.String类型的对象转换为com.photoblog.kyrillos.blog.Model.Users类型

mDatabase = FirebaseDatabase.getInstance().getReference().child("Users").child(mAuth.getCurrentUser().getUid());

mDatabase = FirebaseDatabase.getInstance().getReference().child("Users");
