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"

Include Layout Over Top Scroll to AppBarLayout in Android

I create Layout which consists
CoordinatorLayout
AppBarLayout
CollapsingToolbarLayout
Image
Toolbar
and include one layout for content.
Why the content layout when scroll up is over the toolbar?
This is pic first open Activity
This is pic first open Activity
when scroll down
and scroll up

How can I fix this issue? Does it varies on the phone because when i try it on other phone the layout is ok but on others it is not. how can i fix this issue? I know there are a lot of improper layout on my file. sorry on that.

BottomNavigationView is not showing

When i add the background item in my theme than the BottomNavigationView is disappear.
#color/primary_red
#color/primary_red
and bottomnavigationview
<android.support.design.widget.BottomNavigationView
android:id="#+id/navigation"
android:layout_width="match_parent"
android:layout_height="60dp"
android:layout_gravity="bottom"
design:menu="#menu/bottom_menu_bar" />
When I remove the background item from the theme then it looks like
there is blank space between the window and bottom bar. And also background text is also appearing in foreground. How to remove that.

<android.support.design.widget.BottomNavigationView
android:id="#+id/navigation_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:menu="#menu/navigation"/>

actionBar is goned when input edittext

My issue is the editText on the tabLayout is child fragment , when i input edittext the actionbar will up and disappear.
I try to add the android:windowSoftInputMode="adjustPan" or add ScrollView on the fragment xml, they are no working.
I can't find the same issue on internet.

try it in manifest: add (adjustResize + adjustPan) for parent activity
<activity
android:name="main"
android:windowSoftInputMode="adjustPan|adjustResize"/>

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>
