How to make tablayout fragment fit INSIDE viewpager

Question

I've got a simple fragment for my tablayout/viewpager:

<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    tools:context=".pkgFragment.InputDataOverviewFragment"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"

    >


    <com.google.android.material.appbar.AppBarLayout
        android:id="@+id/abToolBarLayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/BrightYellowCrayola"
        >
        <androidx.appcompat.widget.Toolbar
            android:id="@+id/tbMenuIconWithTitle"
            app:navigationIcon="@drawable/baseline_menu_24"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            app:layout_scrollFlags="scroll|enterAlways"
            app:popupTheme="@style/AppTheme.PopupOverlay"
            >
            <androidx.appcompat.widget.SearchView
                android:id="@+id/svInputdata"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                app:defaultQueryHint="@string/search_incometypes"
                app:iconifiedByDefault="false"
                app:searchIcon="@null"
                app:queryBackground="@android:color/transparent"
                app:submitBackground="@android:color/transparent"
                android:imeOptions="flagNoExtractUi"
                />

        </androidx.appcompat.widget.Toolbar>
        <com.google.android.material.tabs.TabLayout
            android:id="@+id/tabLayoutInputDataTypes"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            app:tabMode="scrollable"
            app:layout_behavior="@string/appbar_scrolling_view_behavior"
            android:background="@color/BrightYellowCrayola"
            />
    </com.google.android.material.appbar.AppBarLayout>
        <androidx.viewpager2.widget.ViewPager2
            app:layout_behavior="@string/appbar_scrolling_view_behavior"
            android:layout_below="@id/tabLayoutInputDataTypes"
            android:id="@+id/viewPagerInputDataTypes"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            />
</androidx.coordinatorlayout.widget.CoordinatorLayout>

And my fragment which is shown when its selected on the tablayout:

<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout 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:focusableInTouchMode="true"

    >

        <androidx.recyclerview.widget.RecyclerView
            android:id="@+id/rvListIncomeType"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:paddingStart="@dimen/zero_margin_when_normal"
            android:paddingEnd="@dimen/zero_margin_when_normal"
            app:layoutManager="androidx.recyclerview.widget.LinearLayoutManager"
            app:layout_behavior="@string/appbar_scrolling_view_behavior"
            />

    <com.google.android.material.floatingactionbutton.FloatingActionButton
        android:id="@+id/fabAddDeleteIncomeType"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom|end"
        android:layout_margin="@dimen/fab_margin"
        android:contentDescription="@string/add_incometype"
        android:minHeight="48dp"
        android:src="@drawable/baseline_person_add_24"
        app:backgroundTint="@color/BrightYellowCrayola" />

</androidx.coordinatorlayout.widget.CoordinatorLayout>

The issue is that the height of my fragment matches my parent fragment and thats why the fragment is height is not fit exactly inside my viewpager:

As you can seen, the floating action button dissapears halfway below and the first toolbar is basically dragged up and it does not appear entirely.

What would be the correct solution to handle the height issue in tablayouts with fragment?

Answer 1

Two lines I removed (currently) in order to make it work:

android:fitsSystemWindows="true"

and

app:layout_scrollFlags="scroll|enterAlways"

I'll keep u updated if it was a smart idea to remove it.
