circlelayoutmanager's Introduction

Android Circle and Zoom LayoutManager for Recyclerview

Examples

####Springback mode

Description

Circle LayoutManager arrays items into a circle. It uses a SparseArray to record every child's rotate degree. Then layout all of children by calculating their x and y position according to their current degree. When scrolling it will transform the swipe distance into offset degree and re-layout all the children. Also it will remove the view which is out of range for reusing.

ScrollZoomLayoputManager will zoom the center view and it will handle the scale while scrolling.

Usage

CircleLayoutManager

circleLayoutManager = new CircleLayoutManager(context);
recyclerView.setLayoutManager(circleLayoutManager);

ScrollZoomLayoutManager

scrollZoomLayoutManager = new ScrollZoomLayoutManager(context,space);
recyclerView.setLayoutManager(scrollZoomLayoutManager);

####To enable springback

recyclerView.addOnScrollListener(new CenterScrollListener());
