To disable scrolling in TabLayout fragment in CollapsingToolbar

To disable scrolling in TabLayout fragment in CollapsingToolbar - android

I have a screen with CollapsingToolbar and below I have a TabLayout with some fragments.
One such fragment has data retrieved with RecyclerView.
The problem is when the screen shrinks the fragment that has the RecyclerView scrolls together and delays the CollapsingToolbar, giving an unwanted effect.
Is there any way I can block the Scroll of the fragment until CollapsingToolbar finishes the process and collapses completely?

<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/cardFeedUser_list" />
</RelativeLayout>

You must use setNestedScrollingEnabled(false) for cardFeedUser_list recyclerView
If you are using API > 21
recyclerView.setNestedScrollingEnabled(false)
If you are using API < 21
ViewCompat.setNestedScrollingEnabled(recyclerView, true);

for the support library, you can easily control your app bar visibility.
setExpanded(true,true);
or
setExpanded(false,true);
Also, you can use DragCallback Method
private void setDragCallback() {
setDragCallback(new DragCallback() {
#Override
public boolean canDrag(#NonNull AppBarLayout appBarLayout) {
return mEnabled;
}
});
}

Solution. Removed NestedScrollView

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"
android:background="#color/grey_very_light_semi_transparent"

You can use Relativelayout as your outer layout and keep CoordinatorLayout inside it, make Two buttons android:layout_alignParentBottom="true"

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"
