Space between the View pager and tabLayout which is inside collpasing toolbar - android

Some empty space is shown after tab Layout. I have the view pager outside the app bar layout and tab layout inside the Relative Layout which is inside of collapsing toolbar. Not able to determine from where this extra space is added. Any help would be appreciated. The hierarchy of the views is Coordinator, App Bar, Collapsing Toolbar, Frame Layout, Relative Layout, Tab Layout.
Below is the code

Is there only in 1 place this extra space or in all AppBarLayout
And u modify in activities those items?
I woud check first behavior those layout at solo and add 1 by 1 next items and then u probly see what's wrong and abou


Here is the solution if required by some one else. If you want your toolbar to be fixed and content to be scrolled under use collapse mode as pin for toolbar and scrollFlags as scroll|exitAlwaysCollapsed for collapsing toolbar

Populating with grid layout manager. I tired to set nested scrolling false. But it didn't work either.
RecyclerView.LayoutManager layoutManager = new GridLayoutManager(this,2);
recyclerView.setLayoutManager(layoutManager);
recyclerView.setNestedScrollingEnabled(false);
Layout which uses recycler view.

Recycler view size changes dynamically which is fetched from an API. If size is say for eg.4, then last 2 card views bottom half are cut off from screen and if size is 5, then last one view is cut off.
Support library used is v24. Anything I am missing here?

I have tried to fix this by elevation but failed to achieve this
can anyone please suggest me what should be the approach to put the layout above floating action button

add this line in your transparent view:
android:translationZ="8dp"

Android Layouts are Z - ordered ie., a layout defined after another will be on top of it visually. Add your transparent view after the container that holds the FAB, that way your transparent view will be on top of the FAB and effectively gets drawn over it.

Define your transparent layout after FAB. Like this -
<android.support.design.widget.FloatingActionButton
android:id="#+id/like_img"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="80dp"
android:background="#color/white"
android:elevation="10dp"
android:src="#drawable/like"
app:fabSize="normal"
app:layout_anchor="#id/app_bar"
app:layout_anchorGravity="bottom|center_vertical" />
<android.support.design.widget.FloatingActionButton
android:id="#+id/fav_img"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:elevation="10dp"
android:src="#drawable/add_to_stylebook"
app:fabSize="normal"
app:layout_anchor="#id/app_bar"
app:layout_anchorGravity="bottom|center" />
<android.support.design.widget.FloatingActionButton
android:id="#+id/share_img"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="70dp"
android:elevation="10dp"
android:src="#drawable/share"
app:fabSize="normal"
app:layout_anchor="#id/app_bar"
app:layout_anchorGravity="bottom|right" />
<View
android:id="#+id/tranparent_view"
android:layout_width="match_parent"
android:layout_height="match_parent"

How to place a layout below toolbar in collapsing toolbar layout?

I want a collapsing toolbar layout in my app. For this I have added the collapsing toolbar inside the app bar. I have added the relative layout with some text views under the layout. This relative layout I want to show below the toolbar and it should get collapsed till the toolbar.
For now as I have added this, Its getting merged with the toolbar. Looks like below:
EDIT : Edited with nested scroll view. Scrolls till the status bar, Should scroll till the toolbar.

How can I place this below toolbar and scroll upto the toolbar? Thank you..

Add this line into your RelativeLayout.
app:layout_behavior="#string/appbar_scrolling_view_behavior"

Put a margin to the RelativeLayout android:layout_marginTop="?attr/actionBarSize"
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/toolbar"
android:layout_marginTop="?attr/actionBarSize"

Always Put your AppBarLayout above your Layout, this solution is tested.. U can try..

Simply add your layout in Coordinatorlayout below NestedScrollView in xml and do the following in java.
CoordinatorLayout.LayoutParams layoutParams = (CoordinatorLayout.LayoutParams) layoutToBeAnchored.getLayoutParams();
layoutParams.setAnchorId(R.id.layoutBelowWhichToBeAnchored);
layoutParams.anchorGravity = Gravity.CENTER;
layoutToBeAnchored.setLayoutParams(layoutParams);
Hope this helps you guys. For any reference you can check the example at -
https://github.com/IsUncommon/Droidcon-India-2015

If your included layout layout="#layout/content_single_product" contains a NestedScrollView as a root view container. Try to add an id to it like #+id/nestedView with android:layout_height="match_parent", You must probably add bottom padding with the same height value of your buttons , and Just keep the rest as it is, and replace android:layout_gravity="bottom" inside your bottom linear layout which contains the two buttons with :
app:layout_anchor="#id/nestedView"
app:layout_anchorGravity="bottom"
