在CoordinatorLayout中使用时,android – footer会在屏幕外滚动

通过单击profile pic,它将使用UserProfileView片段替换该片段. userProfileView片段在coordinatorLayout中有Collapsing工具栏.

userprofileview.xml

                app:resource="@{resourcE}" />

        </LinearLayout>
    </android.support.design.widget.CoordinatorLayout>
</layout>

问题是,当我点击底部导航菜单中的任何其他菜单时,它会滚动屏幕,如下所示.

在UserProfileView framgment中添加CoordinatorLayout后发生此问题.

如果我用LinearLayout替换CoordinatorLayout然后它工作正常但没有获得折叠工具栏的功能.

谢谢！
