I'm facing following problem with custom views in CoordinatorLayout: I need to collapse ViewGroup (f.e LinearLayout) when scrolling RecyclerView. ViewGroup acts as header of RecyclerView. When using following code:
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_height="wrap_content"
android:layout_width="match_parent">
<LinearLayout
android:id="@+id/header"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_scrollFlags="scroll|enterAlways"
android:orientation="vertical">
<!-- TextViews, etc. -->
</LinearLayout>
</LinearLayout>
<android.support.v7.widget.RecyclerView
android:id="@+id/recyclerView"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</android.support.design.widget.CoordinatorLayout>
It doesn't work even if I tried to add property app:layout_bevahiour with appropriate value to recycler's header. RecyclerView will occupy all screen and header(LinearLayout) won't show. But when I change LinearLayout to AppBarLayout, everything works as charm but header is styled as action bar.
Is there any way I can achieve behaviour same as AppBarLayout for any ViewGroup (f.e LinearLayout)?
