I have an activity that has a RecyclerView (optionally in a CardView) and a FloatingActionButton
I want the FAB to be always on screen at the bottom right, but when I scroll to the end of the RecyclerView, the FAB is hiding part of the content on the last item.
Using android:layout_marginBottom="48dp" on the parent CardView (or the RecyclerView itself after removing the CardView) fixes that issue, but it causes the RecyclerView to shrink to the screen size minus the 48dp margin.
I want the RecyclerView to be full size (i.e. fits all items), but when I scroll over the items until I reach the last item, there should be that margin so that the FAB does not cover the last item of the RecyclerView. That is similar to the behavior of the email list in the Google Inbox/Gmail app.
I have seen many questions with similar (but not same) problem, but none of the solutions worked for me. I know there should be some easy fix for this problem, and I don't want to extend LinearLayoutManager, as it seems too much for this problem. I also don't want to hide the FAB on scroll.
Here is what I have so far:

Remove the layout_marginBottom from the CardView and add the following to the RecyclerView:
android:paddingBottom="48dp"
android:clipToPadding="false"

I have a CoordinatorLayout that I want to use to show a header section on top of a RecyclerView. In the wanted behaviour, both have to be scrolled together:
The idea is to place the header in a CollapsingToolbarLayout with scroll and enterAlwaysCollapsed flags:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:id="#+id/home_appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.design.widget.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_scrollFlags="scroll|enterAlwaysCollapsed"
app:scrimAnimationDuration="0">
<LinearLayout
android:id="#+id/header"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<!-- other header elements -->
</LinearLayout>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v7.widget.RecyclerView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layoutManager="LinearLayoutManager"
tools:listitem="#layout/fragment_option_post"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
/>
</android.support.design.widget.CoordinatorLayout>
However, the header (CollapsingToolbarLayout) not always collapses, allowing the RecyclerView content slide behind it. Sometimes the header collapses too late (for ex. when the firsts recyclerview items are already covered by the header), while other times it behaves as expected.
I'm having a problem with Coordinatorlayout and ViewPager implementation.
In order to reproduce this you have to scroll down vigorously and while it's still happening try to scroll the list of items up - a sort of shaky stutter effect can be visible as if CoordinatorLayout was trying to scroll the view in separate direction than its child (RecyclerView).
You can view my layout here:
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/mainContainer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.design.widget.AppBarLayout
android:id="#+id/appBarLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsingToolbarLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<FrameLayout
android:id="#+id/headerContainer"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</android.support.design.widget.CollapsingToolbarLayout>
<android.support.design.widget.TabLayout
android:id="#+id/tabControl"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabIndicatorHeight="4dp"
app:tabMaxWidth="500dp">
</android.support.design.widget.TabLayout>
<LinearLayout
android:id="#+id/topLayout"
android:layout_width="match_parent"
android:layout_height="48dp"
android:orientation="vertical"
android:visibility="gone" />
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/tabContainer"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>
Just to provide some further details:
headerContainer contains ConstraintLayout with some stuff like bunch of textviews, button - pretty usual.
tabContainer contains LinearLayout with list of items (recyclerview)
Add this to the recyclerView in the fragment of your ViewPager..
recyclerView.setNestedScrollingEnabled(false);
This is happening because of the app:layout_behavior="#string/appbar_scrolling_view_behavior" behavior of the viewpager.. this is causing the nestedScrolling.. that is why you feel the shaky effect..
Add this line to your RecyclerView
Recyclerview.setNestedScrollingEnabled(false);
My FAB for some reason won't go to the bottom right corner of the screen as usual. I'm inside a fragment and that fragment is a coordinator layout (I don't know if this is a good practice or not).
Here is the layout xml code:
<android.support.design.widget.CoordinatorLayout 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"
tools:context="com.gigstudios.polls.fragment.MyPollsFragment">
<LinearLayout
android:id="#+id/linear_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_view"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</android.support.v7.widget.RecyclerView>
</LinearLayout>
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="#dimen/fab_margin"
android:src="#drawable/ic_add_white_36dp"
app:fabSize="normal"
app:layout_anchor="#id/linear_layout"
app:layout_anchorGravity="bottom|right|end" />
</android.support.design.widget.CoordinatorLayout>
And for some reason the FAB ends up in the top right instead of the bottom right. Does anyone know what I'm doing wrong?
Btw the xml preview has always shown the fab button in the bottom right corner but when I run it on my phone it's in the top right instead.
Edit: Here's my main_activity xml to show where I'm putting the fragment (The "container" FrameLayout).
<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:background="#color/colorGrey">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
</android.support.design.widget.AppBarLayout>
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/colorGrey"
android:layout_marginTop="?attr/actionBarSize">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/container">
</FrameLayout>
</android.support.v4.widget.NestedScrollView>
</android.support.design.widget.CoordinatorLayout>
The issue is coming due to android.support.v4.widget.NestedScrollView add one more field android:fillViewport="true". Issue was coming as yourNestedScrollView` was not expanding to match parent or take available space. Working fine tested with my code
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/colorPrimary"
android:fillViewport="true"
android:layout_marginTop="?attr/actionBarSize">
</android.support.v4.widget.NestedScrollView>
Remove the lines
app:layout_anchor="#id/linear_layout"
app:layout_anchorGravity="bottom|right|end"
on your FloatingActionButton. They aren't doing anything (since you are anchoring to a view that fills the entire CoordinatorLayout). This will cause your layout_gravity to be respected and your FloatingActionButton will be placed in the bottom right corner of the CoordinatorLayout.
Remove the android:layout_gravity="bottom|end" from your floating action button xml code...it will work
I have a layout (as generated by android studio) where i added a RelativeLayout to the AppBarLayout. The code is below and it looks like this:
Where i am stuck: What i want to achieve is when scrolling the Recyclerview down i want that the green relative layout (which has the id 'controlContainer') scrolls out with it, and when i scroll up it should scroll in (not just on the top but at any place i scroll up in the list)
The Toolbar on top should stay where it is.

android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<include layout="#layout/venue_list" />
</FrameLayout>
I thought that using app:layout_scrollFlags="scroll|enterAlways" in the view that should scroll away combined with app:layout_behavior="#string/appbar_scrolling_view_behavior"should achieve that, but it does not do anything. alternatively, when i add those fields to the toolbar itself both layouts scroll away - which is not what i want, i want the toolbar to stay always fixed.
would be nice if anyone could point me in the right direction here? (i hoped it would be possible with using coordinator layout and not hacking some layout manipulation with onscroll listeners?)
Try this in your toolbar code:
app:layout_collapseMode="pin"
app:layout_scrollFlags="scroll|enterAlways"
I found this link helpful: Scrolling Toolbar
I have 3 views in my layout file with CoordinatorLayout as the root view : AppbarLayout, RecyclerView and a Footer(not visible all the time). Recyclerview implements the default behavior appbar_scrolling_view_behavior, that ideally, brings recyclerview below the appbarlayout. But the recyclerview and footer overlap. To Prevent that, I had to write a custom behavior so that when footer is visible, Recyclerview should make space for the footer. But now, the default behavior of appbar_scrolling_view_behavior is gone and now appbarlayout and recyclerview overlap.Here is the Image of the layout
Link to the custom behavior i implemented:
https://github.com/Mandeep221/CustomBehaviorForRecyclerview/blob/master/CustomBehavior.java
My Question: How can i implement 2 things(simultaneously in one behavior):
get the recyclerview below the appbarlayout inside the co-ordinatorlayout
get the recycelerview to make space for the footer if the footer is visible.
If you can suggest some workaround, that would also be great! Thanks alot!

Don't keep the android.support.design.widget.CoordinatorLayout as root layout.
Add a RelativeLayout as a root layout. Then add android.support.design.widget.CoordinatorLayout with property layout_alignParentTop and layout_above="#+id/footerBar" and set prokure.it.prokure.FooterBarLayout as align parent bottom as second child of RelativeLayout.

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
//footer child views
</LinearLayout>
</prokure.it.prokure.FooterBarLayout>
</RelativeLayout>
Another simpler way is to add following lines to your prokure.it.prokure.FooterBarLayout
app:layout_anchor="#id/list_recycler_view"
app:layout_anchorGravity="bottom"
and keep prokure.it.prokure.FooterBarLayout inside coordinator layout.
Make sure to add an empty cell at the end of the recycler view so that prokure.it.prokure.FooterBarLayout does not overlap with last cell of RecyclerView.
