recycler view on bottom of the screen

I have an RecyclerView that is stuck to the bottom of the screen. I have tried adding constraints but that does not help. If anyone can help it would be appreciated. My code and an image to show whats wrong is below.
RecyclerView stuck at the bottom
<?xml version="1.0" encoding="utf-8"?>

and here is my version of recyclerView items

Set your LinearLayout height match_parent
Check your toolbar height should be wrap_content
Important: Your RecyclerView item layout'parent element should be wrap_content.
Like
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
>
<!--do it match parent-->
<LinearLayout
android:layout_height="match_parent"
>
<include
/>
<android.support.v7.widget.RecyclerView
/>
</LinearLayout>
<android.support.design.widget.NavigationView
/>
</android.support.v4.widget.DrawerLayout>

Use android:layout_weight="1" to get the empty space for the recycleview
<android.support.v7.widget.RecyclerView
android:id="#+id/my_recycler_view"
android:layout_width="match_parent"
android:layout_height="0dp"
android:scrollbars="vertical"
android:layout_weight="1"/>

Set Layout like this
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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="#color/white"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<include layout="#layout/app_bar_map" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:background="#color/white"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="8.5"
android:orientation="vertical">
<android.support.v7.widget.RecyclerView
android:id="#+id/my_recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:background="#color/white"
android:scrollbarSize="0dp"
android:scrollbars="vertical" />
</LinearLayout>
<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_map"
app:menu="#menu/activity_map_drawer" />
</LinearLayout>
</LinearLayout>
Hope this may help you

A really simple solution (if you don't want to debug anymore), try replace your code with
<?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">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<!-- here is the toolbar -->
<include
layout="#layout/app_bar_map"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<android.support.v7.widget.RecyclerView
android:id="#+id/my_recycler_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical" />
</LinearLayout>
<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_map"
app:menu="#menu/activity_map_drawer" />

Transparent Status Bar without coordinatorlayout?

I tried using coordinatorlayout and navigation drawer and making both of them visible under status bar. But when i try to achieve the same thing without coordinator layout it seems impossible to me.

Android layouts overlap

I am including 2 layouts on my activity xml, now I want the second layout to not to overlap the first one but I do not really manage to do it....
Attached is my xml. How can I achieve this?

Place both the "include" in one RelativeLayout and give relative margin between them using either
android:layout_marginTop="15dp"
or
android:layout_marginBottom="15dp"

How to place navigation drawers header below statusbar?

I want my header of my Navigation drawer to be below the statusbar. When searching for solutions, every result is about how to place it under the status bar. I have of course tried to "reverse" theese solutions to place the header below. But it hasn't worked and I'm testing it on a Samsung Galaxy S7 API 23
Right now it looks like this:

Much of this is auto generated by Android Studio after I created my NavigationDrawer Class from the wizard

You have not put your xml fully so I don't know whats wrong with your xml but if you want your navigation drawer below action bar then put your drawerlayout below your toolbar as follows
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<!--Start of the Toolbar and its items -->
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center" />
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"></LinearLayout>
<!--Used for displaying Navigation Drawer slide-->
<LinearLayout
android:id="#+id/navigation_drawer"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:orientation="vertical">
<FrameLayout
android:id="#+id/navigation_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
</android.support.v4.widget.DrawerLayout>
</LinearLayout>
According to your edited question drawerlayout xml would be like
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<include
android:id="#+id/toolbar_drawer_layout"
layout="#layout/navdrawer_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<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:background="#00ffff"
android:fitsSystemWindows="true"
tools:openDrawer="start">
<include
android:id="#+id/activity"

<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"

app:headerLayout="#layout/navdrawer_header"

app:itemTextColor="#fff"
app:menu="#menu/navdrawer_menu"
app:theme="#style/custom_navDrawer_style" />
</android.support.v4.widget.DrawerLayout>

and toolbar layout will be like

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

I used the xml file below to achieve what you asked. But this way, the drawer opens below both the "status bar" and the "toolbar"
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:orientation="vertical"
android:layout_height="match_parent"
tools:context=".MainActivity">
<include xmlns:android="http://schemas.android.com/apk/res/android" layout="#layout/toolbar" />
<android.support.v4.widget.DrawerLayout
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/drawerLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity"
android:elevation="5dp">
<FrameLayout
android:id = "#+id/frameLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
</FrameLayout>
<ListView
android:background="#ffffff"
android:id = "#+id/drawerList"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="left"
android:elevation="5dp"></ListView>
</android.support.v4.widget.DrawerLayout>
</LinearLayout>

How to solve AppBarLayout with DrawerLayout Error

When android:background="#ffffff" is used, first output is observed but the other elements like TextView are not visible.
When android:background="#ffffff" is not used, second output is observed but the other elements like TextView are not visible.
How do I solve this error?

why use fragment for fragment_navigation_drawer????
use from standard code of android studio, like below:
<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">
<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>
and make another xml for your toolbar and content like below:
<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=".MainActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
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_home_page" />
</android.support.design.widget.CoordinatorLayout>
I hope it can help you.
