你还在用Adapter和ViewHolder写RecyclerView吗？Out了！

Yaksa

一个轻量级的RecyclerView工具，让你像Javascript同样渲染Item.

众所周知，熟练使用RecyclerView展现列表数据已是每一个Android开发者必备的能力，然而，RecyclerView仍然有它的不足， 那就是过于繁琐，相信每一个开发者都有过这样的经历，咱们为了展现一个只有单一类型的简单的列表，须要建立一个Adapter， 须要建立一个ViewHolder，而对于具备多个类型的稍微复杂的列表，咱们不但须要建立Adapter，同时还要建立多个ViewHolder..

咱们一次又一次不断的重复着这样无聊的工做，显得那么的麻木不仁

然而，生活不止眼前的苟且，还有诗和远方！

让咱们一块儿和噩梦同样的Adapter和ViewHolder说声再见，一块儿来拥抱Yaksa吧!

Talk is cheap, show me the code

渲染一个Linear列表：

recycler_view.linear {
    item {
        HeaderItem("This is a Header")
    }

    itemDsl(index = 0) {
        xml(R.layout.header_item)
        render {
            it.tv_header.text = "This is a dsl Header"
            it.setOnClickListener { toast("DSL Header Clicked") }
        }
    }

    data.forEach { each ->
        itemDsl {
            xml(R.layout.list_item)
            render {
                it.textView.text = each.title
            }
        }
    }
}
复制代码

就是这样，没有Adapter,也没有ViewHolder，你只须要专心的渲染Item就行了！

渲染一个Grid列表：

rv_list.grid {
    spanCount(SPAN_COUNT)
    
    item {
        HeaderItem("This is a Header")
    }
    
    itemDsl(index = 0) {
        gridSpanSize(SPAN_COUNT)
        
        xml(R.layout.header_item)
        render {
            it.tv_header.text = "This is a dsl Header"
            it.setOnClickListener { toast("DSL Header Clicked") }
        }
    }
    
    data.forEach { each ->
        itemDsl {
            xml(R.layout.list_item)
            render {
                it.textView.text = each.title
            }
            renderX { position, it ->
                it.setOnClickListener { toast("Clicked $position") }
            }
        }
    }
}

瀑布流? 没问题：

rv_list.stagger {
    spanCount(3)
    
    item {
        HeaderItem("This is a Header")
    }
    
    itemDsl(index = 0) {
        staggerFullSpan(true)
        
        xml(R.layout.header_item)
        render {
            it.tv_header.text = "This is a dsl Header"
            it.setOnClickListener { toast("DSL Header Clicked") }
        }
    }
    
    data.forEach { each ->
        item {
            ListItem(each.title, HEIGHTS[Random().nextInt(HEIGHTS.size)].px)
        }
    }
}
复制代码

其他的Header,Footer,多种type类型更是不在话下，并且重要的是，这些都不须要你写任何的ViewHolder和Adapter
