Now want to anchor Recylerview a little bit on ImageView imgAirportBg which is inside CollapsingToolbarLayout. how to do this?
I have added following to RecyclerView
app:layout_anchor="#id/imgAirportBg"
app:layout_anchorGravity="center|bottom"
but it's not working.
solved it by adding following line to recyclerview xml
app:behavior_overlapTop="28dp"

I'm having this problem where I have a recyclerview inside a nestedscrollview, but the nestedscrollview doesn't scroll the recyclerview.
Here is a gif of the situation:
The recyclerview clearly has more children, but nestedscrollview won't scroll to them.
Heres the the framents layout file:

Add this to your recycler view xml
android:nestedScrollingEnabled="true"
Or the same can be done programatically
recyclerView.setNestedScrollingEnabled(true);
I'm trying to create a Collapsing Toolbar Layout using RecyclerLayout.
The problem is that, When I'm inflating the Layout during run time, it's adding a default padding on it's own.
Below are my layout xmls:
activity_profile.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="180dp"
android:fitsSystemWindows="true"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:contentScrim="?attr/colorPrimary"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<ImageView
android:id="#+id/header"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:scaleType="centerCrop"
app:layout_collapseMode="parallax" />
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.design.widget.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="10dp"
app:layout_anchor="#+id/appbar"
app:layout_anchorGravity="bottom|center|end" />
</android.support.design.widget.CoordinatorLayout>
I've tried to remove activity_horizontal_margin as well but it does not seem to work.
Here is the layout that I'm trying to inflate in the recycler-layout:
profile_view.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.constraint.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/colorProfileStatsBackground"
app:layout_constraintBottom_toTopOf="#+id/guideline">
</android.support.constraint.ConstraintLayout>
<android.support.constraint.Guideline
android:id="#+id/guideline"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
app:layout_constraintGuide_percent="0.25" />
</android.support.constraint.ConstraintLayout>
Output:
Finally figured out the problem.
The problem was with android:fitsSystemWindows="true" in AppBarLayout.
I did some research, and found an article fitsSystemWindow which decribes that the default behavior of this attribute is that it sets the padding of the View to ensure the contents don’t overlay the system windows.
I have a fragment with a SwipeRefreshLayout and will be added inside a FrameLayout in the activity on run time.
The problem is that SwipeRefreshLayout height is always 0 whatever the height parameter value is (wrap_content or match_parent).
Here is my fragment code:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/refresh_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="#+id/expensesLL"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.RecyclerView
android:id="#+id/expenses_list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clipToPadding="false"
android:paddingBottom="#dimen/recycler_view_padding_bottom"
android:paddingTop="#dimen/list_item_margin" />
</LinearLayout>
</android.support.v4.widget.SwipeRefreshLayout>
And here is my activity code:
<?xml version="1.0" encoding="utf-8"?>

android:src="#drawable/ic_add"
app:fabSize="normal"
app:layout_anchor="#id/app_bar_layout"
app:layout_anchorGravity="bottom|end" />
</android.support.design.widget.CoordinatorLayout>
Any suggestions please?
The problem solved, I just removed the NestedScrollView and I gave its behavior to the FrameLayout.
I'm trying to implement a recycler view with a collapsing toolbar layout. I have followed this tutorial, but so far my RecyclerView does not show up. All the other views are visible, though.
Here's my layout file:
<?xml version="1.0" encoding="utf-8"?>

<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clipToPadding="false"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<android.support.v4.widget.SwipeRefreshLayout
android:id="#+id/contentView"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.RecyclerView
android:id="#+id/listing_recycler_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
tools:listitem="#layout/item_post" />
</android.support.v4.widget.SwipeRefreshLayout>
</android.support.v4.widget.NestedScrollView>
<TextView
android:id="#+id/errorView"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:visibility="gone" />
</android.support.design.widget.CoordinatorLayout>
The progress bar and the error textview do show up when I toggle them from the code, but the recycler view won't show up.
set recyclerview to actual dp height. It worked for me.
<android.support.v7.widget.RecyclerView
android:id="#+id/listing_recycler_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:listitem="#layout/item_post" />
I would put my FAB on the map
I tried this code but does not work.
My xml file is composed of:
Coordinatorlayout tha including AppBarLayout
that including CollapsingToolbarLayout
that including ImageView
After use a NestedScrollView With LinearLayout
that including A map (com.google.android.gms.maps.SupportMapFragment)
to follow a
FloatingActionButton.
The result is that the FAB is under the Map, and to move the NestedScrollView, i a "tapping" on the bottom.
I use API19 and Android Supporto Design Library, with Android Studio 1.5.
Sorry for the English.

You should put the FAB outside the NestedScrollView
