Hide TabLayout on Scroll of Content instead of ToolBar
Hello is you wish to disappear the toolbar and the tabs still view, you must write the next code:
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_scrollFlags="scroll|enterAlways"
></android.support.v7.widget.Toolbar>
And if you want hide the TabLayout use scrollFlags in the block of TabLayout
app:layout_scrollFlags="scroll|enterAlways"
While doing animation on scroll, CoordinatorLayout starts searching all the children views of AppBarLayout in a linear manner and it stops animating layouts once it finds a layout with non-scrolling tag.
Exp1:
<CoordinatorLayout>
<AppBarLayout>
<layout1 with scrollFlag = "scroll|enterAlways">
<layout2 with no scrollFlag>
</AppBarLayout>
</CoordinatorLayout>
Only layout1 will have animation
Exp2:
<CoordinatorLayout>
<AppBarLayout>
<layout1 with no scrollFlag>
<layout2 with scrollFlag = "scroll|enterAlways">
</AppBarLayout>
</CoordinatorLayout>
None of them will have animation
Exp3: If none of them have scrollFlag, none of them will have animation
Exp4: If both of them have scrollFlag, both of them will have animation
In your case, you'll need to keep toolbar outside the coordinator layout and add tablayout as a child of AppBarLayout with scrollFlags = "scroll|enterAlway"
Try this approach. The main idea is to move Toolbar outside the CoordinatorLayout and wrap this view structure with other container layout.
