Android 数据绑定、表格布局和“；未找到片段”；

android android-fragments

Android 数据绑定、表格布局和“；未找到片段”；,android,android-fragments,android-databinding,Android,Android Fragments,Android Databinding,在我的Android应用程序中，我有一个带有RecyclerView的活动，当用户单击一个项目时，我会调用另一个活动，该活动有一个带有2个片段的TabLayout，每个选项卡用于用户填写的一组字段当我不使用数据绑定时，一切正常，但当我将代码更改为使用数据绑定时，将显示以下错误消息：碎片管理器：找不到id为0x7f0c0072的视图（mypackage:id/container）用于片段 ContatosFormFragment2[…] 碎片管理器：活动状态： AndroidRuntime

在我的Android应用程序中，我有一个带有RecyclerView的活动，当用户单击一个项目时，我会调用另一个活动，该活动有一个带有2个片段的TabLayout，每个选项卡用于用户填写的一组字段

当我不使用数据绑定时，一切正常，但当我将代码更改为使用数据绑定时，将显示以下错误消息：

碎片管理器：找不到id为0x7f0c0072的视图（mypackage:id/container）用于片段 ContatosFormFragment2[…]
碎片管理器：活动状态：
AndroidRuntime:致命异常：主
java.lang.IllegalArgumentException:未找到片段ContatosFormFragment2[…]”的id 0x7f0c0072（mypackage:id/container）的视图

奇怪的是，如果我没有包含ContatosFormFragment1（因此我只有一个选项卡），ContatosFormFragment2就会工作。。。此外，如果我更改选项卡顺序，首先包括ContatosFormFragment2，然后是ContatosFormFragment1，则错误消息为“未找到片段ContatosFormFragment1的视图[…]”

注意：如果您能关注主要问题，我会特别说明，我的意思是，不要担心变量名、封装、代码样式等。。。这是一个初始代码，将在工作时得到改进

下面是带数据绑定和不带数据绑定的代码：
