windowSoftInputMode="adjustPan|adjustResize" did not work with coordinatelayout

I have a layout with multiple EditText and a button in the bottom of it. I want to my layout stay on above of keyboard when keyboard is showing. I search for this problem and I found should put android:windowSoftInputMode="adjustPan|adjustResize" attribute in activity tag of manifest. I do this But did not work for me. I put also android:fitsSystemWindows="true" in the root view. This is my xml Layout file of my fragment:

I have set the elevation and paddingBottom of MyTabs to show the shadow under the tablayout, but in this way the shadown is showed not only on the bottom side but on each side.
I have to show the shadow only on the bottom side, what I have to do ?
OT : this layout is also too slow to be rendered

I have tried putting the scrollview nested inside the main constraint layout and I have also changed the layout to a Scrollview layout and nested a Constraint layout which I also could not get to work. Can someone explain where I am going wrong?

As scrollview is only capable of handling a single view, I would suggest you to wrap everything within a Linear Layout
Use the following code:
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
//PUT ALL OF YOUR ELEMENTS IN HERE
//STARTING WITH...
<android.support.constraint.ConstraintLayout
android:id="#+id/constraintLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="0dp"
android:layout_marginBottom="16dp"
android:layout_marginEnd="8dp"
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"
android:layout_marginStart="8dp"
android:layout_marginTop="8dp"
android:background="#color/colorPrimaryDark"
android:padding="40dp"
app:layout_constraintBottom_toTopOf="#+id/emailEditText"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
..............REMAINING ELEMENTS.............
//AND ENDING WITH
<Button
android:id="#+id/fbSignInButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginEnd="8dp"
android:layout_marginLeft="8dp"
android:layout_marginRight="8dp"
android:layout_marginStart="8dp"
android:layout_marginTop="14dp"
android:background="#drawable/pink_button"
android:text="#string/fb_button"
android:textColor="#fff"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/orTextView" />
</LinearLayout>
</ScrollView>

The problem is that the first two TextViews are getting cropped and an unnecessary padding is added at the bottom of the NestedScrollView.
A similar bug was filed a few months before but I think it's not solved yet.
Similar questions have been asked before, but I can't find the proper solution to it.

Take a look at android:layout_gravity="center" on the ConstraintLayout nested within the NestedScrollView. Try to either remove this attribute or set it to android:layout_gravity="center_horizonal". I am not quite sure what it means to center a View vertically in a NestedScrollView.

In my situation, there is a app:layout_constraintBottom_toBottomOf="parent" in the child view of ConstraintLayout.
<TextView
android:id="#+id/textView11"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/choose_position"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.061"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/chip_group_time"
app:layout_constraintVertical_bias="0.027" />
Delete the layout_constrainBottom_toBottomOf. My NestedScrollView work!!!!
<TextView
android:id="#+id/textView11"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/choose_position"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.061"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/chip_group_time"
app:layout_constraintVertical_bias="0.027" />
Be careful to use app:layout_constraintBottom_toBottomOf="parent" in NestedScrollView > ConstraintLayout . Because it make the layout fixed

How to put 'spinner' on top of button

Is there a way I can make my spinner be put on top of my button? (There will be various things on top of my button and when you press the button everything thats on it including the button will disappear)(the button spans the width of the screen) Now it's my spinner under my button. I tried looking at different RelativeLayout settings but it didn't work. Here's the xml code below

Edit: I put my button and spinner into a frame layout, and when I tested it on my phone it works. However I tested it on a phone of a bigger size (and a newer android version) and the spinner doesn't show up (probably hidden again?) No idea why it would work on one phone but not the other,

Try calling

I think I managed to sort something out - I created a 'FrameLayout' and put both my spinner & button in there.
Should do the job, unless I find an issue, in which I'll come back here,this should be solved. :) Thank you

In case anyone was wondering:
I put my 'button' into a FrameLayout then put the elements I want 'ontop' of it, under it (as in the code under it) like so:
