首先，我想对我的英语错误表示抱歉。我有一个带有回收站视图的片段，其中我有用于创建广告的表单字段。在Recycler视图中，我使用字段（标题，价格，描述，类型等）制作持有者（标题）。持有物品（照片），持有人（页脚）带按钮＆＃34;创建广告＆＃34;。

当我单击按钮创建（在页脚持有者中）时，我在标题中调用方法createDeclaration（）。在这个方法中，我从我的字段（EditTexts，Spinners，CheckBoxes，RadioButtons）收集所有数据，并在创建类FormOfDeclaration（在我的例子中，在我的情况下称为类CreateDeclarationFormHolder）中保存所有字段。我返回此类后到我的片段和片段我向服务器发出拉取请求以创建广告使用Retrofit 2.Method createDeclaration in holder（header）将在下面：

当我第一次制作广告时，我的问题代码没有问题，但是如果我转到另一个片段或活动后，例如它可以是我的菜单或其他应用程序的部分，之后我将再次回到片段＆＃34;创建广告＆＃34;我试图用字段中的新数据创建新广告，我的应用程序工作不错，它试图创建这个广告，但我的第二次所有字段都保持空白!!!!!!!为什么会这样？ =（
