I want to add a toolbar in my bottom navigation view. I try to add a Toolbar but it doesn't add it to the top
toolbar_image
It might be the "android:paddingTop="?attr/actionBarSize">"
I don't undestand it use but when I remove it, I can't see the design of the layout
nav_bar.xml code:

It will work.You should set a mother layout. android:paddingTop="?attr/actionBarSize" This is padding from top of same size of action bar. This line should be delete.Then toolbar will be right top in the layout.
The issue come from android:paddingTop="?attr/actionBarSize" line in your root view. You should delete that line to remove the top blank spacing

I want the toolbar to collapse when user starts scrolling content inside my FragmentContainerView but I want the BottomNavigationView to stay in the screen. This is my code:

Here's the fragment loading inside FragmentContainerView:
<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">
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
...
...
...
</androidx.constraintlayout.widget.ConstraintLayout>
</ScrollView>
The current behavior of the code above is that you can scroll the page only if you select the app bar as starting point, and it won't scroll otherwise. That's because the bottom parts of the child fragment are going behind the BottomNavigationView. How can I fix this?
I have a problem using coordinator layout with bottom navigation bar, the fragment container appear to be under the bottom navigation bar.

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"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"

<FrameLayout
android:layout_width="match_parent"
android:layout_height="0dp"
app:layout_constraintTop_toBottomOf="#id/appBarLayout"
app:layout_constraintBottom_toTopOf="#id/nav_view"/>
<androidx.fragment.app.FragmentContainerView
android:id="#+id/nav_host_fragment_activity_main"
android:name="androidx.navigation.fragment.NavHostFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:defaultNavHost="true"
app:navGraph="#navigation/mobile_navigation" />
<com.google.android.material.bottomnavigation.BottomNavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_behavior="#string/hide_bottom_view_on_scroll_behavior"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:menu="#menu/bottom_nav_menu" />
</androidx.constraintlayout.widget.ConstraintLayout>
I am working with ConstraintLayout which has basically two views inside it: AppBar Layout and the Navhost Fragment but the view inside fragment either overlaps with the app bar layout or doesnot scroll fully to the bottom. Here is what i've done:
<?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"

android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#f0f8fe"
tools:context=".Activities.MainActivity">
<com.google.android.material.appbar.AppBarLayout
android:id="#+id/app_bar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
android:orientation="vertical"
>
<androidx.appcompat.widget.Toolbar
android:id="#+id/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" />
I wanted to implement FrameLayout with toolbar for scrolling_view_behaviour.
But when I set layout_height of FrameLayout to match_parent, it overflows as shown in the picture below:
this is my layout file:
<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="match_parent"
tools:context=".ui.NewsActivity">

android:id="#+id/appBar"
android:layout_width="match_parent"

>
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolbar"

android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways"
app:titleTextColor="#fff" />
</com.google.android.material.appbar.AppBarLayout>
<FrameLayout
android:id="#+id/flFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
app:layout_insetEdge="start">
<fragment
android:id="#+id/navHostFragment"
android:name="androidx.navigation.fragment.NavHostFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:defaultNavHost="true"
app:navGraph="#navigation/news_nav_graph" />
</FrameLayout>
<com.google.android.material.bottomnavigation.BottomNavigationView
android:id="#+id/bottomNavigationView"
android:layout_width="match_parent"
android:layout_height="56dp"
android:layout_gravity="bottom"
android:background="#fff"
app:layout_behavior="#string/hide_bottom_view_on_scroll_behavior"
app:layout_insetEdge="bottom"
app:menu="#menu/bottom_navigation_menu" />
</androidx.coordinatorlayout.widget.CoordinatorLayout>
I am sorry if this question is repeated or silly, I couldn't find anything which could solve my problem. Thanks in advance
You can remove attributes which refer to ConstraintLayout because you are not using one here. Also the FrameLayout. Adding margin to bottom of Fragment will set it in proper way.
<androidx.coordinatorlayout.widget.CoordinatorLayout

<androidx.appcompat.widget.Toolbar
android:id="#+id/toolbar"
style="#style/Widget.AppCompat.Toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways"
app:titleTextColor="#fff" />
</com.google.android.material.appbar.AppBarLayout>
<fragment
android:id="#+id/navHostFragment"
android:name="androidx.navigation.fragment.NavHostFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginBottom="112dp"
app:defaultNavHost="true"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
app:navGraph="#navigation/news_nav_graph"
tools:ignore="FragmentTagUsage" />
<com.google.android.material.bottomnavigation.BottomNavigationView
android:id="#+id/bottomNavigationView"
android:layout_width="match_parent"
android:layout_height="56dp"
android:layout_gravity="bottom"
android:background="#fff"
app:menu="#menu/bottom_navigation_menu" />
</androidx.coordinatorlayout.widget.CoordinatorLayout>
As you can see i have added
android:layout_marginBottom="112dp"
But if you add 56dp to it, it will put bottom 56dp layout behind BottomNavigationView. To avoid that inside child fragments which are in other layouts just add more 56dp to it.
I have an issue with placing fragment and making it scroll without being overlapped by bottomNavigationView and AppBar. So my content is covered by BottomNavigationView and AppBar.How i can make my content visible when I am scrolling page or appBar and BottomNavigationView invisible while scrolling page down?

Make the height of your fragment tag that hold nav host fragment 0dp
In your activity_main.xml
<fragment
android:layout_marginTop="130dp"
android:id="#+id/dataContainer"
android:name="androidx.navigation.fragment.NavHostFragment"
android:layout_width="409dp"
android:layout_height="673dp" ---------> ( make it 0dp )
app:defaultNavHost="true"
