I created the default bottom navigation project. In one of the fragments I added a ListView, that worked fine. Then I changed that to a RecyclerView, it gets obscured by the BottomNavigationView. What am I doing wrong?
Here is the layout for the main activity:
<?xml version="1.0" encoding="utf-8"?>

</android.support.constraint.ConstraintLayout>
When the RecyclerView contains more rows than fit on the screen, then the last row appears partially behind the BottomNavigationView. I would be grateful for any suggestions.
Edit - here is a screenshot:
Edit #2: In the first layout, if I move the BottomNavigationView inside the LinearLayout (thanks #Juanje), and change its android:layout_width from 0dp to match_parent, then the RecyclerView is no longer obscured by the BottomNavigationView, but now the FloatingActionButton is cast adrift:
I am tinkering with it, I would be grateful for any ideas.
Edit #3
Below is what I ended up with after following the accepted answer plus a couple other tweaks. The necessary changes were:
1) In the first layout:
Move the BottomNavigationView inside the LinearLayout
In the BottomNavigationView, change android:layout_width from "0dp" to "match_parent"
2) In the second layout:
In the FloatingActionButton, change android:layout_marginBottom
from "70dp" to "10dp"

You need to set some constraints, otherwise your elements overlap. Use this:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout 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"
tools:context=".MainActivity">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:orientation="vertical"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toTopOf="#id/navigation"> <!--Added here and one line above; changed height: 0dp height means match constraint-->
<android.support.v7.widget.Toolbar
android:id="#+id/my_toolbar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:background="?attr/colorPrimary"

app:popupTheme="#style/ThemeOverlay.AppCompat.Light"/>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" />
</LinearLayout>
<android.support.design.widget.BottomNavigationView
android:id="#+id/navigation"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginEnd="0dp"
android:layout_marginStart="0dp"
android:background="?android:attr/windowBackground"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:menu="#menu/navigation" />
</android.support.constraint.ConstraintLayout>
You should include the BottomNavigationView inside the LinearLayout.
The important attributes for fragment element is setting android:layout_height="0dp" to match the constrains layout and adding app:layout_constraintBottom_toTopOf="#id/nav_view" to make the fragment be above the BottomNavigationView.
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout

app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"

<fragment

app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toTopOf="#id/nav_view"
app:navGraph="#navigation/mobile_navigation" />
</androidx.constraintlayout.widget.ConstraintLayout>
Here is my solution with SwipeRefreshLayout:
<?xml version="1.0" encoding="utf-8"?>

android:layout_width="match_parent"
android:layout_height="0dp"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
<androidx.recyclerview.widget.RecyclerView
android:id="#+id/people_list"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</androidx.swiperefreshlayout.widget.SwipeRefreshLayout>
</androidx.constraintlayout.widget.ConstraintLayout>
BottomNavigationView is wrapped by ConstraintLayout and looks like:
<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:elevation="0dp"
app:menu="#menu/navigation"/>

I am using BottomNavigationView and AppBarLayout.
But the content at the bottom of the AppBarLayout is cut off as in the picture.
How do I make everything visible? (I can't move the graph upwards because there is something to add at the top of the graph.)
Below is the XML code of the screen in the picture: (Fragment)

How can I arrange the elements to create the fragment container between the top app bar and bottom navigation view?
It's been 10 months ago, i think it's kinda late to answer
i just face the same problem... To solve it you need to wrap your coordinatorLayout inside constraintLayout, like this:
<constraintLayout>
<coordinatorLayout>
<AppBarLayout>
</AppBarLayout>
<FrameLayout>
</coordinatorLayout>
<BottomNavigatioNView>
</constraintLayout>
this is the example of mine:
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 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:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".ui.main.MainActivity">
<androidx.coordinatorlayout.widget.CoordinatorLayout
android:layout_width="0dp"
android:layout_height="0dp"
app:layout_constraintBottom_toTopOf="#+id/nav_bottom"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
<com.google.android.material.appbar.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/primary_900"
app:elevation="0dp">
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?actionBarSize"
android:textAlignment="center"
app:titleTextColor="#color/white" />
</com.google.android.material.appbar.AppBarLayout>
<androidx.fragment.app.FragmentContainerView
android:id="#+id/nav_host_fragment_activity_home"
android:name="androidx.navigation.fragment.NavHostFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:defaultNavHost="true"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
app:layout_constraintBottom_toTopOf="#id/nav_bottom"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:navGraph="#navigation/mobile_navigation" />
</androidx.coordinatorlayout.widget.CoordinatorLayout>
<com.google.android.material.bottomnavigation.BottomNavigationView
android:id="#+id/nav_bottom"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:background="#color/primary_900"
app:itemIconTint="#color/nav_color"
app:itemTextColor="#color/nav_color"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:menu="#menu/bottom_nav_menu" />
</androidx.constraintlayout.widget.ConstraintLayout>
and make sure you set width and height of CoordinatorLayout to 0dp.
Hope it helpful.
Before
after
Wrap whole layout with LinearLayout and set it's property orientation to vertical. Than Move AppBar and BottomNavigation outside of CoordinatorLayout.
Your widget tree should be like this:
<LinearLayout>
<Appbar/>
<CoordinatorLayout/>
<BottomNavigation/>
</LinearLayout>
Instead of CoordinatorLayout you can use ConstraintLayout.
<?xml version="1.0" encoding="utf-8"?>

How can I be able to position the FrameLayout to be always below the toolbar without setting margin_top as actionbarsize? I would like to have finer control over its position.
You can make the height as match constraints (0dp), and constraint it at the bottom to the parent and at the top to the Toolbar

android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="?attr/colorPrimary" />
</com.google.android.material.appbar.AppBarLayout>
<fragment
android:id="#+id/nav_host_fragment"
android:name="androidx.navigation.fragment.NavHostFragment"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:defaultNavHost="true"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/app_bar"
app:navGraph="#navigation/nav_graph" />
</androidx.constraintlayout.widget.ConstraintLayout>
And the view layout inside fragment:
<androidx.core.widget.NestedScrollView 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"
android:fillViewport="true"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context=".ScrollingFragment">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="#dimen/text_margin"
android:text="#string/large_text" />
</androidx.core.widget.NestedScrollView>
I tried the solutions here, does not seem to work
Try to change height of <fragment> to 0dp.
<fragment
android:id="#+id/nav_host_fragment"
android:name="androidx.navigation.fragment.NavHostFragment"
android:layout_width="match_parent"
android:layout_height="0dp"
app:defaultNavHost="true"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/app_bar"
app:navGraph="#navigation/nav_graph" />
How can I make the FrameLayout end with the beginning of the BottomNavigationView? The content of the FrameLayout is being overlapped by the navigation view.
This is the xml:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
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" tools:context="...">
<FrameLayout
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
<android.support.design.widget.BottomNavigationView
android:id="#+id/navigation"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginEnd="0dp"
android:layout_marginStart="0dp"
android:background="?android:attr/windowBackground"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:menu="#menu/navigation" />
</android.support.constraint.ConstraintLayout>
In case you want to keep using constraintlayout, you may add the following attributes to the framelayout in the xml:
android:layout_width="match_parent"
android:layout_height="0dp"
app:layout_constraintBottom_toTopOf="#+id/navigation"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
This one worked for me. (Inspired by jackycflau)
<?xml version="1.0" encoding="utf-8"?>

<FrameLayout

Try this:
<RelativeLayout
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_height="match_parent">
<FrameLayout
android:layout_above="#+id/navigation"
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:layout_editor_absoluteY="8dp"
tools:layout_editor_absoluteX="8dp" />
<android.support.design.widget.BottomNavigationView
android:id="#+id/navigation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?android:attr/windowBackground"
android:layout_alignParentBottom="true"
app:menu="#menu/action_admin_bottom_menu" />
</RelativeLayout>
