XAdapter 快速创建NodeAdapter（Android RecyclerView）

XAdapter 是一个对 Android RecyclerView Adapter 的轻量级封装库，基于kotlin特性，可以做到 。

XAdapter 目录

单布局Node创建

• 数据类必须实现NodeEntity接口，并重写getChildNodeEntityList()方法

data class NodeInfo(val name: String, val child: MutableList<NodeInfo>? = null) : NodeEntity<NodeInfo?, NodeInfo>{
    override var xParentNodeEntity: NodeInfo? = null
    override var xNodeGrade: Int? = null

    override fun getChildNodeEntityList(): MutableList<NodeInfo>? {
        return child
    }
}

• 调用nodeAdapter方法创建Adapter

val adapter = nodeAdapter<ItemNodeBinding, NodeInfo> { 
    
    }

多布局Node创建

• 数据类必须实现NodeEntity接口，并重写getChildNodeEntityList()方法

data class AreaNode(val name: String) : NodeEntity<CityNode, Unit> {
    override var xParentNodeEntity: CityNode? = null
    override var xNodeGrade: Int? = null
    override fun getChildNodeEntityList(): MutableList<Unit>? {
        return null
    }
}

data class ProvinceNode(val name: String, val city: MutableList<CityNode>) : NodeEntity<Unit, CityNode> {
    override var xParentNodeEntity: Unit? = null
    override var xNodeGrade: Int? = null

    override fun getChildNodeEntityList(): MutableList<CityNode> {
        return city
    }
}

data class CityNode(val name: String, val area: ArrayList<AreaNode>) : NodeEntity<ProvinceNode, AreaNode> {
    override var xParentNodeEntity: ProvinceNode? = null
    override var xNodeGrade: Int? = null

    override fun getChildNodeEntityList(): MutableList<AreaNode> {
        return area
    }
}

• 调用nodeAdapter和withType方法创建Adapter

val adapter = nodeAdapter()
    .withType<ItemNodeBinding, ProvinceNode> {
        
    }.withType<ItemNodeBinding, CityNode> { 
        
    }.withType<ItemNodeBinding, AreaNode> {
        
    }.toAdapter()
