android-coordinatorlayout

I am using CoordinatorLayout in my activity page. In that there is ListView below the app bar. But its not working when I use ListView instead of NestedScrollView . And if I put ListView inside NestedScrollView , ListView is not expanding For the CoordinatorLayout to work properly you need the scrolling child to implement NestedScrollingChild . Such classes are NestedScrollView and RecyclerView . To say it short - just use a RecyclerView for your scrolling content and it'll work correctly :) P.S. As a side note, I don't see a reason why you'd use a ListView anymore. I know it's a habit and it

I want to hide/show FloatingActionButton on scroll of RecyclerView . My XML layout : <android.support.design.widget.CoordinatorLayout android:layout_width="match_parent" android:layout_height="match_parent" > <android.support.v7.widget.RecyclerView android:id="@+id/recyclerview_eventlist" android:layout_width="match_parent" android:layout_height="match_parent" /> <android.support.design.widget.FloatingActionButton android:id="@+id/fab_createevent" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_margin="@dimen/fab_margin" app:layout_anchor="@id

Should it be set at the AppBarLayout sibling's parent or at the first Scrollable View inside its sibling? With Material Design for Android , there are Views that let us work with the behavior of the layout depending on its surroundings, one of them is the CoordinatorLayout , as this CodePath guide mentions: CoordinatorLayout extends the ability to accomplish many of the Google's Material Design scrolling effects. Currently, there are several ways provided in this framework that allow it to work without needing to write your own custom animation code. The one I'm interested in now is: Expanding

Just had a look at the demo app of new Android support design library. It's provided by Chris Banes on github . Throught the app, CoordinatorLayout is used Heavily. Also, many of the support design library classes such as FloatingActionButton , SnackBar , AppBarLayout etc. behaves differently when used inside CoordinatorLayout . Can someone please shed some lights on what is CoordinatorLayout and how it is different from other ViewGroup s in android, or at least provide correct path towards learning CoordinatorLayout . Here it is you are looking for. from docs the Design library introduces

Is it really intended that the Toolbar in a AppBarLayout is scrollable although the main container with the "appbar_scrolling_view_behavior" has not enough content to really scroll? What I have tested so far: When I use a NestedScrollView (with "wrap_content" attribute) as main container and a TextView as child, the AppBarLayout works properly and does not scroll. However, when I use a RecyclerView with only a few entries and the "wrap_content" attribute (so that there is no need to scroll), the Toolbar in the AppBarLayout is scrollable even though the RecyclerView never receives a scroll
