And this is my physical devices unexpected output:-
I don't understand why this output act like that and which is totally unexpected. how I resolve this issue.

Since your CardView is not constrained by the buttons at the bottom the CardView will take space beyond those buttons. In the screenshot provided from a real device, it is clear that there is not much space to completely accommodate the contents in the CardView hence it will be pushed beyond the button. You need to add constraints to CardView to align it with the bottom button also you need to add a ScrollView if there is more content that the screen can't fully accommodate. Using this layout may improve the UI

How to display a custom clickable menu from XML under clicked button in Android?

I have a custom XML file for the options menu which I want to display underneath an ImageButton when it is clicked. I want to be able to get the id (or a name, index...) of the item from the menu when the item is selected.
Here's the XML file of recycler_view_item.xml which is the layout with the ImageButton that's supposed to show the menu on click:

I've been trying to find the solution for quite some time, but I'm quite new and to be honest, I don't even know what exactly I'm supposed to be searching for. Your help is greatly appreciated and sorry if this was posted in the past.
Thank you in advance.

How to scroll layout when keyboard pops up in android

I have made the following layout using coordinator layout. But when the keyboard pops up some of the elements go below the keyboard hence losing the visibility.
So please help me to fix that.I have tried putting adjustPan, adjustResize in windowSoftInputMode but still not working. Even tried with the nested scroll view, no success.

Use card view to top root then use any other layout with in it...!

Well you can use Scrollview,It will enable scrolling. So you can scroll all layout upside and downside.Do try this, if you don't want this you can also check Collapsing Toolbars. From here

You can't center crop a background image of linear layout,
But you can achieve the same using these changes:
Replace you LinearLayout with RelativeLayout
Place a ImageView as a first child inside relative layout and use property for center crop.
<RelativeLayout
android:id="#+id/background_image"
android:layout_width="match_parent"
android:layout_height="210dp"
android:orientation="vertical">
<ImageView
android:scaleType="centerCrop"
android:src="#drawable/club1"
android:layout_width="match_parent"
android:layout_height="match_parent" />
.....
......
</RelativeLayout>

If you Want to control The Image View Scale
you need to put it in ImageView As Src Not Background
You can use Frame layout To Achieve it

CenterCrop logic is baked inside ImageView. The correct solution is to extract it into a Drawable which wraps another Drawable and centerCrops it.

If you use CoordinatorLayout, then just to put your ImageView with centerCrop parameter to top.
<CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:scaleType="centerCrop"
android:background="#drawable/background_main"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#android:color/transparent"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:elevation="0dp">
<include layout="#layout/header_main" />
<TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabIndicatorColor="#android:color/white"
android:background="#drawable/white_border_background"
app:tabIndicatorHeight="3dp"/>
</AppBarLayout>
<ViewPager
android:id="#+id/view_pager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</CoordinatorLayout>

Relative RecyclerView Scrolling

I have an image and some text and below that i have a sliding tab layout with a view pager and the view pager has 3 fragments each having one recycler view each . Now my problem is that i want to scroll the recyclerview and at the same time i want to scroll the rest of the elements too. For eg when i scroll the recycler view i want all other views to scroll as well. This my XML layout

Google + Does that , i would like to implement something simillar

I believe Google used a Collapsing Toolbar Layout, which will collaps the toolbar on scroll or other events.
You can find more information here.
<android.support.design.widget.AppBarLayout
android:layout_height="192dp"
android:layout_width="match_parent">
<android.support.design.widget.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<android.support.v7.widget.Toolbar
android:layout_height="?attr/actionBarSize"
android:layout_width="match_parent"
app:layout_collapseMode="pin"/>
</android.support.design.widget.CollapsingToolbarLayout>
