I am trying to add a recycler view on a Drawer Layout. The problem is that the RecyclerView, which is in a separate document content_main.xml, is placed behind the Toolbar found in the main document activity_main.xml.
activity_main.xml

I tried adding app:layout_behavior="#string/appbar_scrolling_view_behavior" as found in this answer but it did not work. I also changed the height from match_parent to wrap_content
In your RecyclerView xml layout add
android.support.v7.widget.RecyclerView
android:clipToPadding="false"
android:paddingTop="56dp"
android:paddingBottom="56dp
Check the question:
Android what does the clipToPadding Attribute do?

I am having an issue where the Cardview is bring 'blocked' by the top Action Bar as seen in the image
How can I fix the issue where I do would not have to put a 'padding-top' value in order to resolve.
Here is my files for you review:

BTW: As you can see I am using fragments.
Check your recyclerview layout
give some margin from top
use this

android:id="#+id/recycler_view"
android:layout_marginTop="?attr/actionBarSize"
android:layout_height="match_parent">

In my project, I have added a Drawer Layout which as has a coordinatorLayout. The coordinatorLayout has a AppBarLayout, how can i place the BottomNavigationView to the bottom of Coordinator Layout?
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout

<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent">

android:layout_width="match_parent">

<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="android.support.design.widget.AppBarLayout$ScrollingViewBehavior"
android:fillViewport="true">
<include
android:id="#+id/layout" layout="#layout/activity_main_body"
android:layout_height="match_parent"
android:layout_width="match_parent"/>
</android.support.v4.widget.NestedScrollView>
<android.support.design.widget.BottomNavigationView
android:id="#+id/navigation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
<!-- I had anchor_gravity="bottom" but that didn't work-->
android:background="#color/secondaryColor"
app:itemIconTint="#color/secondaryDarkColor"
app:itemTextColor="#color/primaryTextColor"
app:menu="#menu/bottom_navigation_items"/>
</android.support.design.widget.CoordinatorLayout>
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true" />
</android.support.v4.widget.DrawerLayout>
This is the code, how should i place the BottomNavigationView?
Just add android:layout_gravity="bottom" in android.support.design.widget.BottomNavigationView
and it should go to the bottom of the screen.
<android.support.design.widget.BottomNavigationView
android:id="#+id/navigation"
android:layout_width="match_parent"
android:layout_gravity="bottom"
android:layout_height="wrap_content"
android:background="#color/secondaryColor"
app:itemIconTint="#color/secondaryDarkColor"
app:itemTextColor="#color/primaryTextColor"
app:menu="#menu/bottom_navigation_items"/>
I am trying to get the content below AppBar but it doesn't work. Here is the the code of the layout of my activity :
<?xml version="1.0" encoding="utf-8"?>

<ListView
android:id="#+id/counters_list"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</LinearLayout>
</android.support.constraint.ConstraintLayout>
I have tryied the solution given in other stackoverflow posts like app:layout_behavior="#string/appbar_scrolling_view_behavior" but it doesn't work. It gives this :
I have tryied with this android:layout_marginTop="?android:attr/actionBarSize" and it works but I still would like to understand how to get app:layout_behavior="#string/appbar_scrolling_view_behavior" working.
If you don't need AppBarLayout then you can change your MainActivityLayout like this
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout 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/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay" />
<FrameLayout
android:id="#+id/contentFrame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab_add_counter"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="#dimen/fab_margin"
app:fabSize="normal"
app:layout_anchor="#id/contentFrame"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
app:layout_anchorGravity="bottom|right|end" />
</RelativeLayout>
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="#layout/nav_header_home"
app:menu="#menu/activity_home_drawer" />
</android.support.v4.widget.DrawerLayout>
Try changing your content layout to following:
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
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=".home.HomeActivity">
<LinearLayout
android:id="#+id/countersLL"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ListView
android:id="#+id/counters_list"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</LinearLayout>
</android.support.constraint.ConstraintLayout>
I think this will solve your problem. Because app:layout_behavior is not used correctly in your layout. You need to use it on the layout that contains your content which is your ConstraintLayout in here, not LinearLayout. In addition, It seems that LinearLayout in your layout is useless, unless you are going to add something dynamic inside it.
UPDATE
OOPS my mistake. I didn't notice that your content is a fragment. Change main layout to following and remove app:layout_behavior from your content layout:
<FrameLayout
android:id="#+id/contentFrame"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
android:layout_width="match_parent"
android:layout_height="match_parent" />
How do I move FloatingActionButton only to specific fragment layout that I want? For example, only show to fragment B, while fragment A eliminated.
My code
activity_main
<?xml version="1.0" encoding="utf-8"?>

Here I want to move FloatingActionButton from app_bar_main to fragment_channel layout.
When I try, I get a look messy when moving android.support.design.widget.CoordinatorLayout and FloatingActionButton inside fragment_channel.
How is the correct way to put Floating Action Button only on the layout of a particular fragment (in this case fragment_channel) ?
Here is what I did in my case. Hope it helps you.
- app_bar_main.xml
<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:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.bertho.tdashboard.MainActivity"
>
<android.support.design.widget.AppBarLayout
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_main"/>
</android.support.design.widget.CoordinatorLayout>
- content_main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
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"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:showIn="#layout/app_bar_main"
tools:context="com.bertho.tdashboard.MainActivity">
<FrameLayout
android:id="#+id/root"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</RelativeLayout>
And now in you fragment_channel.xml put FrameLayout as parent and before close it, put your FAB.
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<android.support.v4.widget.SwipeRefreshLayout
android:id="#+id/swipe_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="#+id/movies_recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</android.support.v4.widget.SwipeRefreshLayout>
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="end|bottom"
android:layout_margin="#dimen/fab_margin"
android:src="#drawable/ic_new_user" />
</FrameLayout>
To finish, remove the FAB code in MainActivity and implement it in your ChannelFragment.java.
Hope Helpful
I have a layouting problem when combining CoordinatorLayout with an AppBarLayout and a NavigationDrawer.
The problem is, that the NavigationDrawer and it's content are hidden behind the toolbar. I have already did a lot of research and tried a lot of restructuring, but none of the "solutions" fixed my issue.
A demonstration can be found in this little Webm video: https://www.dropbox.com/s/i5zfc2x2ts2fws7/navigation_drawer_stackoverflow32523188.webm?dl=0
The base style is Theme.AppCompat.Light.NoActionBar.

Your CoordinatorLayout is wrapping your DrawerLayout and NavigationView, which means the Coordinator is in control of how everything is laid out. You need to nest the Coordinator inside the drawer, like so:
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:focusableInTouchMode="true">
<android.support.design.widget.CoordinatorLayout

android:id="#+id/overview_coordinator_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"

That should sort it out!
To add on to the previous answer, you can make the DrawerLayout cleaner by moving the CoordinatorLayout+child elements into a separate xml file. And then just use the "include" option to add the file.
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout 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/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">
<!-- Widget Coordinator + child elements go here -->
<include
layout="#layout/app_bar_main"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="#layout/nav_header_main"
app:menu="#menu/activity_main_drawer" />
</android.support.v4.widget.DrawerLayout>
