RecyclerView 仅显示两个文本视图？其他不显示...项目不显示

Question

我遇到了一个问题，比如只显示了两个项目，其他两个项目没有显示，它们是联系的，平坦的，没有这个项目没有显示......我也尝试删除和添加其他文本视图，但通过这个只显示两个项目。 ...现在我想在似乎不起作用的 RecyclerView 上显示数据，我很确定我的代码很好，但有些东西似乎不起作用而且我找不到它。我也尝试stackoverflow 建议的所有事情，但什么都不会发生，所以我想我需要问...... 文件在这里

请使用以下pojo并尝试。

public class RecieptModel
{
    private String MobileNo;

    private String Amount;

    private String Flat_no;

    private String Name;

    public String getMobileNo ()
    {
        return MobileNo;
    }

    public void setMobileNo (String MobileNo)
    {
        this.MobileNo = MobileNo;
    }

    public String getAmount ()
    {
        return Amount;
    }

    public void setAmount (String Amount)
    {
        this.Amount = Amount;
    }

    public String getFlat_no ()
    {
        return Flat_no;
    }

    public void setFlat_no (String Flat_no)
    {
        this.Flat_no = Flat_no;
    }

    public String getName ()
    {
        return Name;
    }

    public void setName (String Name)
    {
        this.Name = Name;
    }

    @Override
    public String toString()
    {
        return "ClassPojo [MobileNo = "+MobileNo+", Amount = "+Amount+", Flat_no = "+Flat_no+", Name = "+Name+"]";
    }
}
