Java Firebase数据库异常可以'；t从模型转换字符串类型的对象

我的应用程序崩溃了。 我想知道我从firebase获取数据的路径是否导致它崩溃

这是我的班级：

package com.handymanapp.handymanapplication.Model;

import com.google.firebase.database.Exclude;

import java.util.HashMap;
import java.util.Map;

public class Post {

String jobname;
String jobwage;
String jobarea;
String jobenvironment;
String jobdesc;
String contactnumber;
String jobtype;
String jobtime;

public Post() {

}

public Post(String jobname, String jobwage, String jobarea, String 
jobenvironment, String jobdesc, String contactnumber, String jobtype, String 
jobtime, String imageUrl) {
    this.jobname = jobname;
    this.jobwage = jobwage;
    this.jobarea = jobarea;
    this.jobenvironment = jobenvironment;
    this.jobdesc = jobdesc;
    this.contactnumber = contactnumber;
    this.jobtype = jobtype;
    this.jobtime = jobtime;
}


public void setJobname(String jobname) {
    this.jobname = jobname;
}

public void setJobwage(String jobwage) {
    this.jobwage = jobwage;
}

public void setJobarea(String jobarea) {
    this.jobarea = jobarea;
}

public void setJobenvironment(String jobenvironment) {
    this.jobenvironment = jobenvironment;
}

public void setJobdesc(String jobdesc) {
    this.jobdesc = jobdesc;
}

public void setContactnumber(String contactnumber) {
    this.contactnumber = contactnumber;
}

public void setJobtype(String jobtype) {
    this.jobtype = jobtype;
}

public void setJobtime(String jobtime) {
    this.jobtime = jobtime;
}

public String getJobname() {
    return jobname;
}

public String getJobwage() {
    return jobwage;
}

public String getJobarea() {
    return jobarea;
}

public String getJobenvironment() {
    return jobenvironment;
}

public String getJobdesc() {
    return jobdesc;
}

public String getContactnumber() {
    return contactnumber;
}

public String getJobtime() {
    return jobtime;
}

}

以下是我的主要活动：

    post = database.getInstance().getReference().child("Advertisement-post");

    recycler_menu = (RecyclerView)findViewById(R.id.recycler_job);
    recycler_menu.setHasFixedSize(true);
    layoutManager = new LinearLayoutManager(this);
    recycler_menu.setLayoutManager(layoutManager);

    loadMenu();

}

private void loadMenu() {

    FirebaseRecyclerAdapter<Post,PostViewHolder> adapter = new FirebaseRecyclerAdapter<Post, PostViewHolder>(Post.class,R.layout.job_item,PostViewHolder.class,post) {
        @Override
        protected void populateViewHolder(PostViewHolder viewHolder, Post model, int position) {
            viewHolder.jobnameview.setText(model.getJobname());
            viewHolder.jobwageview.setText(model.getJobwage());
            viewHolder.jobareaview.setText(model.getJobarea());
            final Post clickItem = model;
            viewHolder.setItemClickListener(new ItemClickListener() {
                @Override
                public void onClick(View view, int position, boolean isLongClick) {
                    Toast.makeText(joblist.this,""+clickItem.getJobname(), Toast.LENGTH_SHORT).show();

                }
            });
        }
    };
    recycler_menu.setAdapter(adapter);

}


}

当我创建一篇新文章时，我使用push生成id，所以我尝试在recycler视图中检索它。我不知道节点的路径是怎样的

这是我的推送：

mUserDatabase = FirebaseDatabase.getInstance().getReference().child("Advertisement-post").push();

你有崩溃的堆栈跟踪吗？您可以从adb logcat获得它，或者甚至可以从Firebase获得它，如果您已经设置了崩溃报告，则可以向您显示问题所在，以及它无法转换为模型的确切字符串。一旦你确定了这一点，请将其编辑到你的问题中（如果这不能为你解决问题的话）。没关系，我已经找到了问题。模型类名必须与我的firebase节点相同。所以你解决了这个问题？如果没有，请添加您的数据库结构。

mUserDatabase = FirebaseDatabase.getInstance().getReference().child("Advertisement-post").push();
