FlowLayout
FlowLayout 是一个自定义 Android 视图小部件，旨在将子元素换行显示在多行上。它作为一个基于适配器的布局，从数据源填充和更新流式内容，专门用于显示标签或芯片集合。
该组件包括一个标签选择系统，支持具有可配置限制的单选或多选模式。它通过标签点击处理来管理用户交互，并包含一个状态管理器，以在 Activity 重建和屏幕旋转期间持久化选择索引。
该库提供了动态数据填充和自动布局测量功能，以确保元素根据可用的水平屏幕空间正确换行。
Features
- Custom Layouts - Provides a custom layout manager that calculates child positions to wrap elements across multiple lines.
- Tag and Flow Layouts - Provides a specialized flow layout for displaying and wrapping collections of tags or chips.
- Android UI Components - Develops reusable custom view containers for Android that handle dynamic content and tag interactions.
- Adapter-Based Layouts - Uses an adapter pattern to dynamically populate and update flowing content from a data source.
- Adapter-Based View Generation - Populates the flowing layout with dynamic data using a custom adapter to generate child views.
- Adapter Based Mappings - Implements an adapter pattern to dynamically map a data source to view holders for flowing content.
- Flow Layouts - Allows child views to wrap automatically across multiple lines when horizontal screen width is exceeded.
- Selection Logic - Manages single or multiple item selection states for tags through a central controller.
- Multi-Select Tag Groups - Ships a selectable UI component for Android that manages single and multiple tag selection modes.
- View Dimension Measurement - Determines child layout bounds during the measurement phase to ensure correct wrapping based on parent constraints.
- Screen State Managers - Persists tag selection states across activity reconstruction and screen rotations to maintain UI state.
- Configuration Change Persistence - Maintains selected item indices during Android activity rotations and configuration changes.
- Selection State Persistence - Saves and restores the current selection of items during activity reconstruction to prevent data loss.
- Layout Managers - Flow layout implementation.
