## Description

Twoway-view is a Java library for Android list UI development designed to simplify the creation of custom list and grid interfaces. It focuses on reducing repetitive boilerplate code when building complex item arrangements and custom layouts.

The project provides tools for custom layout manager design and sequence layout management, allowing for precise structural positioning of items. It includes mechanisms for list layout simplification and the rendering of custom user interface layouts.

The library covers a broad range of list capabilities, including item decoration management for visual styling, interaction primitives for input processing and selection tracking, and navigation utilities for animated scrolling to specific positions.
