android-appbarlayout

I'm trying to get the toolbar to collapse on scroll when a recyclerview inside a fragment is scrolled. To start, heres my main layout: <DrawerLayout> <RelativeLayout android:id="@+id/mainRelativeLayout" android:layout_width="match_parent" android:layout_height="match_parent" > <android.support.design.widget.CoordinatorLayout android:layout_width="match_parent" android:layout_height="wrap_content" > <android.support.design.widget.AppBarLayout android:id="@+id/appBarLayout" android:layout_width="match_parent" android:layout_height="wrap_content" > <Toolbar android:id="@+id/toolbar" android

I have a AppBarLayout which contains an horizontal RecyclerView among its children. The sibling of the AppBarLayout is a ViewPager (which contains a vertical RecyclerView ). Here is the XML: <android.support.design.widget.CoordinatorLayout android:id="@+id/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=".ui.search.SearchResultFragment"> <android.support.v4.view.ViewPager android

In the GIF below you'll see I'm having trouble coordinating (heh) an AppBarLayout , containing a CollapsingToolbarLayout , and a Persistent BottomSheet in such a way that they play nicely together Goal: Have the fragment contents , seen above in turquoise ( #26999f ), remain above, yet scroll behind, the BottomSheet, seen above in dark green (#12783e) , while also respecting the AppBarLayout and its Behavior Again, as you can see from the GIF I'm close; the fragment contents is using a custom layout_behavior , MyScrollingViewBehavior , which extends AppBarLayout.ScrollingViewBehavior In the

I have a fragment that uses the new CoordinatorLayout/AppBarLayout/CollapsingToolbarLayout paradigm, and I'd like to be able to detect when the collapsing toolbar is fully expanded so that I can perform an operation on the entire fragment it's in, e.g. popping the fragment off the stack and going to a new one, dismissing the fragment. I have the dismissing code working, I just need to know when and when not to use it. I've experimented a bit with AppBarLayout.OnOffsetChangedListener , but didn't have much luck. Is there a way to use it to determine when things are completely expanded, or is

How can I set the colour of icons (home and overflow menu icon) in a Toolbar / AppBarLayout programmatically ? I want to change the toolbar's colour scheme for a single fragment in an activity. Setting the AppBarLayout 's background to a light colour (e.g. light gray with appBarLayout.setBackgroundResource(..); ) results in white icons and a white title which are barely visible. Its layout is as follows: <android.support.design.widget.AppBarLayout android:id="@+id/appbar" android:layout_width="match_parent" android:layout_height="wrap_content" android:fitsSystemWindows="true"> <android.support
