I've added a new FloatingActionButton class that mimics the behavior of the original one but works with the upcoming RecyclerView, which is not an AbsListView.

My previous pull request for RecyclerView support was replaced with this one.

I also updated the sample to use AppCompat, so Material theming is used (and supports KitKat and below) along with the ripple effect and elevation on the FAB. The demo GIF was updated to reflect that.

The FAB will use the elevation API instead of the shadow drawable on API 21. It will have a ripple selector on Lollipop and above also. I made another attribute (fab_colorRipple) that can be used to customize the color of the ripple so it can be seen over the color of the FAB, it defaults to white. I made the references to Holo Blue use Material Blue instead.

If items of a list view have different height, then animation to show/hide FAB when scrolling isn't smooth sometimes. I think it is due to assumption in getListViewScrollY method that all items have the same height.

When the number of ListView items is at the point where they fill all/most of the screen, but still fit within the screen so no scrolling is yet possible/activated the button covers the bottom list items. Since, one of the main features of this particular FAB library is that the FAB hides when scrolling I would suggest attaching to swipe up/down motions instead of onScrollDown() and onScrollUp().

I can't seem to figure out how to set the fabs to push up/down on a SnackBar show/hide.

I read it's setMovement...

However I can't get it to work.

Thanks, Jon.

On GB, when you use the animation as used on NineOldAndroids, you need to know that if a View moves from point A to point B using an animation, it's actually still on point A. It's not the library's fault. That's how it works on GB. Animations don't really change the view itself.

This means that when you hide the floating action button, and then click when it was a moment ago, it's still being clicked.

What you need to do is to ditch this library, add a normal translateAnimation, and when it's done its animation, hide the view (using setVisibility(View.GONE) ). When you need to show it again, you will set its visibility back.

Another possible approach is to play with its margins values instead of an animation. That's ok for simple layouts, but could cause bad performance on complex ones.

Another possible approach is to never show any animation, and just add a footer at the bottom that's large enough to be below the floating action item.

Hello, First of all allow me to thank you. This custom view is amazing :) I was trying to implement it in my app to check how it works and I encountered an issue. If I populate the ListView (or GridView in my case), using a LoaderManager, there might be an IndexOutOfBounds exception when calculating scroll Y if the list hasn't finished populating yet.

I tried attaching the view to the GridView in onLoadFinished and that seems to work only if there is a small amount of data to populate.

I'm trying to solve this right now, but if you have any lead, that would be awesome!

And thanks again.

EDIT: I added a check if (mAdapter.getCount() != 0) in onLoadFinished() before attaching the GridView to the FloatButton.... this way I make sure there is info in the adapter once the attached method gets called. I hope its stable enough...

How can I make the action bar and my tab bar hide when the float button hides..

I use a RecyclerView. I don't understand the documentation and I couldn't find examples. Nice library by the way!

If i attach two fabs to the same list view only one listens the onScroll so only one hides when scrolling. Is there a way to attach both of them to onScroll? Thanks

I'm getting

java.lang.ClassNotFoundException: android.graphics.drawable.shapes.OvalShape

exception while editing layout in Android Studio 0.8.11.

Anyone else experiencing this or should we really modify createDrawable method to add isInEditMode() modification?

• Allow custom OnScrollListeners to be attached to list view;
• Work properly with list of different height rows;
• Ignore tiny shakes of fingers, by using min_significant_scroll

Fix #21 and fixes #22

The base class limited application of lib. Because it requires a special base object, that restricts java class design.

Can it work with interface or android base class like ScrollView or etc?

Is there a way to remove the attachedScrollview? so my floatingactionbutton isn't listening anymore to the scrollview programaticly.

I need to add the scrollview in the beginning of launching the activity. but if the user presses a button the floatingactionbutton need to stop listening to the scoll.
