你還在用Adapter和ViewHolder寫RecyclerView嗎？Out了！

Yaksa

一個輕量級的RecyclerView工具，讓你像Javascript同樣渲染Item.

衆所周知，熟練使用RecyclerView展現列表數據已是每一個Android開發者必備的能力，然而，RecyclerView仍然有它的不足， 那就是過於繁瑣，相信每一個開發者都有過這樣的經歷，咱們爲了展現一個只有單一類型的簡單的列表，須要建立一個Adapter， 須要建立一個ViewHolder，而對於具備多個類型的稍微複雜的列表，咱們不但須要建立Adapter，同時還要建立多個ViewHolder..

咱們一次又一次不斷的重複着這樣無聊的工做，顯得那麼的麻木不仁

然而，生活不止眼前的苟且，還有詩和遠方！

讓咱們一塊兒和噩夢同樣的Adapter和ViewHolder說聲再見，一塊兒來擁抱Yaksa吧!

Talk is cheap, show me the code

渲染一個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
            }
        }
    }
}

就是這樣，沒有Adapter,也沒有ViewHolder，你只須要專心的渲染Item就行了！

渲染一個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? 沒問題：

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)
        }
    }
}

其他的Header,Footer,多種type類型更是不在話下，並且重要的是，這些都不須要你寫任何的ViewHolder和Adapter
