RecyclerView仅显示两个textview？其他未显示…项目未显示

Question

我有一个问题，就像只显示了两个项目，其他两个项目却没有显示，它们是接触式的，也没有平面的。这个项目也没有显示...我也尝试了删除和添加其他文本视图，但是仅显示了两个项目。 ..现在我想在似乎无法正常工作的RecyclerView上显示数据，我很确定自己的代码是好的，但是似乎无法正常工作，而且我找不到它。 stackoverflow建议的事情，但是什么都不会发生，所以我认为我需要问...这里文件

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+"]";
    }
}
