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

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

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"

android:gravity="bottom"
android:paddingLeft="30dp"

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

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

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.

Specyfy what u meen ( is there inside of tab layout or outside the best print printscreen)
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

To disable scrolling in TabLayout fragment in CollapsingToolbar

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?

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

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"
