Why is my Toolbar not collapsing when scrolling? - android

I am wanting my Toolbar to collapse/hide when scrolling down the recycler view in this fragment however when trying what it says in other posts, it still isn't scrolling. I have tried to add app:layout_scrollFlags="scroll|enterAlways" to my toolbar as well as app:layout_behavior="#string/appbar_scrolling_view_behavior" to my viewpager but neither seems to work. Here is my code:

following code works for me in my project...just try adjusting in your code

The solution was removing the Relative Layout in activity_main.xml. I am not exactly sure the happenings behind why, but I believe it was somehow causing my toolbar to not close as expected because otherwise it would ruin the Relative Layout potentially? Here is the updated code:
activity_main.xml

Scrollview overlapping on fragments

The following is my activity_scrolling.xml
<?xml version="1.0" encoding="utf-8"?>

tools:context="com.example.visualcovid_19.ScrollingActivity"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
<include layout="#layout/content_scrolling" />
</androidx.coordinatorlayout.widget.CoordinatorLayout>
The following is my content_scrolling.xml
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context=".ScrollingActivity"
tools:showIn="#layout/activity_scrolling">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<include
layout="#layout/country_card_fragment"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<include
layout="#layout/country_card_fragment"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
</ScrollView>
But, I end up getting the scroll view overlapped on map fragment and right below AppBarLayout
a screenshot is attached below.
I want the scroll view to start at the end of the map fragment and the initial scroll should take the AppBarLayout and the fragment below it to the top as usual and the rest scroll view should be able to scroll.

Try to remove tools:showIn="#layout/activity_scrolling" from content_scrolling.xml. Also, try to not include your cards, use the full code.

Coordinatorlayout doesnt work with included toolbar

I have an appBarLayout with a toolbar and tabs and a pageview with a nested scroll and scroll flags so the toolbar disapears when i scroll inside the pageview, if the bar and pageview is in the same layout under coordinatorlayout it all works fine, but if i move the appBarLayout and include it in the main layout it doesnt anymore, i have no idea why. This is what i have:
<?xml version="1.0" encoding="utf-8"?>

So I've got a fragment with a CoordinatorLayout as follows:

This is the layout for my MainActivity:

app:menu="#menu/sidenav_menu"
app:headerLayout="#layout/navigation_header">
</android.support.design.widget.NavigationView>
</android.support.v4.widget.DrawerLayout>
The fragment gets added using the FragmentManager to replace the FrameLayout. However, when I scroll up on the CoordinatorLayout, the title on my ActionBar isn't centered vertically. This is what happens:
How do I get the action bar title to center? Thanks!
EDIT: Sorry about the huge images

Just use android:paddingBottom="10dp" inside your toolbar.
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"

Android - Views with alignParentBottom = "true" are not visibles in ViewPager

I'm implementing an app with Toolbar, TabLayout, ViewPager and CoordinatorLayout. The property layout_behavior = "#string/appbar_scrolling_view_behavior" in ViewPager causes an extra space in the bottom as illustrated.
How I can I put views with alignParentBottom = "true" in the ViewPager and that they are visible and not hidden in the part that is not visible? Thank you

Here, TextView position is at the bottom of the DrawerLayout.

Toolbar collapse on scroll with Drawer Layout, Coordinator Layout, and Fragments

I'm trying to get the toolbar to collapse on scroll, but no matter what answer I follow I cannot seem to get it to collapse on scroll. The fragment that gets inflated in the FrameLayout is a View Pager if that makes a difference. Any help would be greatly appreciated.
