How To Hide AppBar When Scrolling Down

I have an AppBar and other things in my layout. When the user scrolls down, I want AppBar(actually, the Toolbar to hide. This is what I have tried, the app bar isn't hiding all small part it just stays there. Actually I think the problem is with my header of the screen it gets collapsed and adds a small space when I scroll.
As you can see in second image some part stays it doesn't hide. I need to hide that part while scrolling.
Please provide me solution what am I doing wrong?

Answer to the problem is just remove
android:fitsSystemWindows="true"

Change the layout_scrollFlags
app:layout_scrollFlags="scroll|exitUntilCollapsed"
replace above line with
app:layout_scrollFlags="scroll|enterAlways|enterAlwaysCollapsed"

The problem is that the UI is cut when the keyboard is uploaded.
So I solved it with the [adjustpan] option.
This is the same result as I intended.
But I can't even see the "toolbar."
I always want to show "toolbar" at the top.

I'll attach the image to the current situation more easily.

BottomNavigationView doest not shown currectly

I'm adding a BottomNavigationView to My MainActivity
at first show nothing wrong but after click on other items, BottomNavigationView strangely moving up and down. In other projects, I had never this problem and I don't know why I am getting this:
p.s: In default fragment (which is first at right in screenshot) I have a content but in other fragments, I have no content.
Here is my MainActivity 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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.activity.MainActivity">
<FrameLayout
android:id="#+id/MainActivity_FrameLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/MainActivity_BottomView" />

app:elevation="2dp"
app:itemTextColor="#android:color/white"
app:itemIconTint="#android:color/white"

and here is the screenshot of how does shown
after clicking on another item
and when select default item again

Thanks in advance for your guidance.

Change your root layout to LinearLayout like below:
<?xml version="1.0" encoding="utf-8"?>

<FrameLayout
android:id="#+id/MainActivity_FrameLayout"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" />
<android.support.design.widget.BottomNavigationView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/colorPrimary"

app:elevation="2dp"
app:itemTextColor="#android:color/white"
app:itemIconTint="#android:color/white"
android:id="#+id/MainActivity_BottomView" />

I found a solution by myself,i have to use scrollView include the toolaBar.Just like above
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.Toolbar
android:id="#+id/id_toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:theme="#style/ToolBarStyle"
app:layout_scrollFlags="scroll|enterAlways"
android:background="#FF6699">
<TextView
android:id="#+id/textTitle"
android:textSize="18dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#android:color/background_light" />
</android.support.v7.widget.Toolbar>
</ScrollView>

Fab gets focus only sometimes

I have a problem testing the focusability of my App with D-pad. Here there are two screenshots of my App:
In the picture of the left side, the fab is "outside(or below)" the list and after the last element it gets the focus when navigating down, so everything is ok in this case. The problem comes with the image of the right side. The fab is "inside" the listView and for that reason(I think but I'am not sure) it doesn't get ever the focus. Is there anything that can be done about it?
An enhacement would be that the fab would get the focus always before the list(that is immediately after the tabs), no matter where the fab is positioned at the momment in the layout, but the problem is that I don't know how to do it, since Android decides the focus order of my Layout.
Any help would be highly appreciated.

You can create a separate Layout and put your fab there. This will force that part to always be seen.
For example
<LinearLayout>
//list stuff here
<LinearLayout>
//fab stuff
</LinearLayout>
</LinearLayout>
