Android LinearLayout and RecyclerView BottomNavigation Alignment

so I can't figure out how to align my bottom navigation in a LinearLayout under a RecyclerView. The items are RecyclerView:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
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:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".CategoryActivity">
<android.support.design.widget.AppBarLayout
android:theme="#style/AppTheme.AppBarOverlay"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize">
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_category"
android:layout_margin="8dp"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
</android.support.v7.widget.RecyclerView>
<android.support.design.widget.BottomNavigationView
android:id="#+id/nav_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?android:attr/windowBackground"
android:layout_alignParentBottom="true"
app:menu="#menu/bottom_nav_menu"/>
</LinearLayout>
The navigation should be always at the bottom.

Okay, here is your layout, it should work as you expected
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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.support.design.widget.AppBarLayout
android:id="#+id/appbar"
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>
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_category"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/nav_view"
android:layout_below="#+id/appbar"
android:layout_margin="8dp"
android:orientation="vertical" />
<android.support.design.widget.BottomNavigationView
android:id="#+id/nav_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="?android:attr/windowBackground"
app:menu="#menu/menu_navigation" />
</RelativeLayout>

Not sure but try adding this:
android:layout_gravity="bottom"

If you don't want to change to RelativeLayout, set this attribute to the RecyclerView:
android:layout_weight="1"
This way the RecyclerView will take all the available space pushing the BottomNavigationView to the bottom.

You Can't adjust your BottomNavigationView properly inside LinearLayout. If there are so many items in your RecyclerView then BottomNavigationView will be hidden at the bottom. So you must use RelativeLayout to align it at the bottom and other layouts above of BottomNavigationView. Please check the bellow modified layout.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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:layout_width="match_parent"
android:layout_height="wrap_content"

android:layout_width="match_parent"

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="?android:attr/windowBackground"
app:menu="#menu/menu_navigation" />
</RelativeLayout>

How to fix a gap between AppBarlayout and TabLayout

I'm trying to use a AppBarLayout with Toolbar a TabLayout component and a Viewpager, but I'm getting a black gap between toolbar and tablayout, and not really sure why. I've taken a look some examples of here and they don't work.
I put an image of my problem.

That doesn't seem to be a good practice-design in my view. You used CoordinatorLayout and TabLayout inside it and so much more issues.
Instead, use CoordinatorLayout as the root layout and after AppBarLayout as it's child, then Toolbar and TabLayout inside AppBarLayout.
So, the structure will be:
<CoordinatorLayout
<AppBarLayout
<Toolbar/>
<TabLayout/>
</AppBarLayout>
<ViewPager/>
<CoordinatorLayout/>
After that, use ViewPager inside CoordinatorLayout like this and add the following line of code:
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/white"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>

ViewPager under ActionBar in RelativeLayout

ViewPager is below ActionBar. How can I make it under it?
layout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay"
app:elevation="0dp">
<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>
<android.support.design.widget.BottomNavigationView
android:id="#+id/bottom_navigation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
app:itemBackground="#color/colorPrimary"
app:itemIconTint="#drawable/selector"
android:background="#color/colorPrimary"
app:itemTextColor="#drawable/selector"
app:menu="#menu/activity_homebottomnav" />
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#id/bottom_navigation"
android:layout_below="#id/appbarlayout"
android:layout_alignParentTop="true"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</RelativeLayout>
It's on top of BottomNavigationView as it should be, but is under ActionBar.
app:layout_behavior="#string/appbar_scrolling_view_behavior"
android:layout_below="#id/appbarlayout"
Doesn't work. And I don't want to use android:layout_marginTop="?android:attr/actionBarSize"
Thanks.

Put the AppBarLayout and the ViewPager under a android.support.design.widget.CoordinatorLayout and it should work as the behavior you're specifying only works under a CoordinatorLayout

How to make AppBarLayout stick to top of layout

I want the AppBarLayout to to stick to the top of the screen when the soft keyboard appears, but it always gets pushed offscreen.
The activity has android:windowSoftInputMode="adjustPan" (also tried setting it to default).
I've tried setting app:layout_scrollFlags="scroll|enterAlways|snap" on the AppBarLayout (and various configurations of this property).
And I've tried wrapping the AppBarLayout in a CoordinatorLayout and setting android:layout_alignParentTop="true" and app:layout_constraintStart_toStartOf="parent", app:layout_constraintBottom_toBottomOf="parent".
How can I get the desired effect?
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/holo_green_light"
android:fitsSystemWindows="true"
tools:openDrawer="end">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay"
app:layout_scrollFlags="scroll|enterAlways|snap"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintBottom_toBottomOf="parent">
<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/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</android.support.design.widget.AppBarLayout>
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#color/colorSecondary"
android:fitsSystemWindows="true"
app:headerLayout="#layout/nav_header_main"
app:itemBackground="#drawable/drawer_menu_highlighted_item_background_color"
app:itemIconTint="#drawable/drawer_menu_highlighted_item_text_color"
app:itemTextAppearance="#style/GlobalMenuText"
app:itemTextColor="#drawable/drawer_menu_highlighted_item_text_color"
app:menu="#menu/activity_main_drawer" />
</android.support.v4.widget.DrawerLayout>

Use below code:
1.First set id for your AppBarLayout android:id="#+id/text1" then set you FrameLayout below AppBarlayout android:layout_below="#+id/text1"
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/text1"
android:theme="#style/AppTheme.AppBarOverlay"
app:layout_scrollFlags="scroll|enterAlways|snap"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintBottom_toBottomOf="parent">
<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>
<FrameLayout
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/text1"/>
</RelativeLayout>

I have tried most of the answers which i have found in Stack overflow still i was unable to get it done. Am I doing something wrong? will someone please help me out with this trying to get this done sense 1 week.

Can you elaborate more on what is going wrong? The biggest issue I see here is that you have the exitUntilCollapsed flag set on your CollapsingToolbarLayout's layout_scrollFlags. If you are unable to get the Toolbar to scroll off screen, that is the culprit. Your AppBarLayout needs to be set up like this:
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary">
<android.support.design.widget.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:contentScrim="?attr/colorPrimary"
app:titleEnabled="false"
app:layout_scrollFlags="scroll">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin" />
</android.support.design.widget.CollapsingToolbarLayout>
<android.support.design.widget.TabLayout
android:id="#+id/tab_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</android.support.design.widget.AppBarLayout>
Can't embed images yet. Click here for gif.
Also, if all you need is to have the Toolbar scroll off-screen, you don't need a CollapsingToolbarLayout. You can just have the Toolbar with app:layout_scrollFlags="scroll", like so:
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_scrollFlags="scroll"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
<android.support.design.widget.TabLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</android.support.design.widget.AppBarLayout>
This is the best resource I've found for explaining all of the different scroll flags for AppBarLayout and CollapsingToolbarLayout: http://saulmm.github.io/mastering-coordinator
