BottomNavigationView overlapping FrameLayout in CoordinatorLayout

Question

The following is my layout xml. The problem now is that the BottomNavigationView is overlapping the FrameLayout. I wanted the FrameLayout to stretch to the top of the BottomNavigationView.

I tried with trick such as adding paddingBottom in the FrameLayout but I wonder if there is other better solution. Thanks.

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >

    <include layout="@layout/user_app_bar"/>

    <android.support.design.widget.BottomNavigationView
        android:id="@+id/navigation"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        android:background="?android:attr/windowBackground"
        app:menu="@menu/navigation"
        app:itemTextColor="@color/colorPrimaryDark"
        app:itemIconTint="@color/colorPrimaryDark"
        />

    <FrameLayout
        android:id="@+id/fragment_frame"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:paddingBottom="58dp"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"/>

   <android.support.design.widget.FloatingActionButton
       android:id="@+id/fab"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:layout_margin="@dimen/fab_margin"
       app:layout_anchorGravity="bottom|end"
       app:layout_anchor="@id/app_bar"
       app:srcCompat="@drawable/ic_edit_white_24px" />

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

UPDATE: more information on the user_app_bar.xml. It contains a CollapsingToolbarLayout.

you will have to give fixed height (you can do it dynamically by calculating screen height and deducting bottombar height ) to be always on top of the bottomview layout, or you can use relative layout and assign bottom property — Aalap Patel, Sep 08 '17 at 13:45
I need to use CoordinatorLayout as I have AppBarLayout in the user_app_bar layout file. — hjchin, Sep 09 '17 at 13:16

There is simple solution for your issue. That is to put marginBottom in FrameLayout on 56dp which is according to documentation height of BottomNavigationView. I'm not sure is it changable acording to mobile screens. Even the documentation says nothing about changing of height. And I used it in some of my apps and I didn't find that height of BottomNavigationView is changing. But just in case check. Hope this will help.

I need to use CoordinatorLayout as root layout as I have AppBarLayout in the user_app_bar layout file. – hjchin Sep 09 '17 at 13:17
If you don't have `TabLayout` inside yout app_bar_ layout.xml then just use topmargin see my edite answer – Yupi Sep 09 '17 at 13:27
I added the app_bar layout file on above. I can't use a fixed height as AppBarLayout has a CollapsingToolbarLayout in it. – hjchin Sep 09 '17 at 13:54
Then there is simple solution use your previous xml layout and just put bottom margin in `FrameLayout 56dp` that is the height of bottom navigation view. I don't know is it changable. See on different screens but I think height will remain `56dp` – Yupi Sep 09 '17 at 14:52
Actually I'm using this approach but with paddingBottom. I was thinking if there is a better approach than this. Thanks for the input. – hjchin Sep 10 '17 at 02:07

Place CoordinatorLayout and BottomNavigationView inside RelativeLayout

Good a better solutions without having to hardcode the bottomView

You can put it inside a ConstraintLayout and make the height of the content 0dp and also set it's bottomToTop="@id/bottomViewId" or whatever is the Id you put to the bottomViewNavigator.

Here is an example.

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".StartActivity">

    <fragment
        android:id="@+id/nav_controller"
        android:name="androidx.navigation.fragment.NavHostFragment"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintBottom_toTopOf="@id/bottom_navigation"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:defaultNavHost="true"
        app:navGraph="@navigation/nav_graph" />

    <com.google.android.material.bottomnavigation.BottomNavigationView
        android:id="@+id/bottom_navigation"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        android:background="@color/colorPrimary"
        app:itemIconTint="@android:color/white"
        app:itemTextColor="@android:color/white"
        app:menu="@menu/bottom_navigation_menu" />
</androidx.constraintlayout.widget.ConstraintLayout>

Could you provide a complete solution with the user_app_bar.xml? I needed CoordinatorLayout because I have CollapsingToolbarLayout in user_app_bar.xml. I do think ConstraintLayout sounds promising to solve this problem. — hjchin, Jul 30 '18 at 04:55

add this line in your BottomNavigationView android:background="?android:attr/windowBackground"
