RecyclerView-AbsoluteLayoutManager

Implement RecyclerView custom layout as easy as UICollectionViewLayout.

Why

Implementing custom RecyclerView.LayoutManager is much more difficult than UICollectionViewLayout in iOS. Key difference is that LayoutManager fills visible child views relative to already placed child view, on other hand UICollectionViewLayout calculates absolute position of each cell.

Although relative approach enables to handle wrap_content on child views, but is too complicated if you don't want it.

Usage

Implement AbsoluteLayoutManager.LayoutProvider. It is just same as UICollectionViewLayout. :)

See example.

TODO

• Decoration margin is not supported yet.
• Predictive animation is not supported yet.

Compatibility

Tested with recyclerview-v7:22.1.1.

Installation

Gradle:

dependencies {
    compile 'com.android.support:recyclerview-v7:X.Y.Z'
    compile 'net.ypresto.recyclerview.absolutelayoutmanager:absolutelayoutmanager:0.2.0'
