我正在开发一个无限滚动的产品列表,其中包含不同类型的产品。产品可以是特色或不特色。当产品出现时,我们的产品卡设计会占用手机的整个宽度,否则设计需要2列的行
数据看起来像这样:
[
{
"type": "featured-product",
"name": "Product",
"description: "yadda yadda"
},
{
"type": "product",
"name": "Another Product",
"description: "yadda yadda"
},
{
"type": "product",
"name": "And Another Product",
"description: "yadda yadda"
},
{
"type": "product",
"name": "One more Product",
"description: "yadda yadda"
}
{
"type": "product",
"name": "Yet another",
"description: "yadda yadda"
},
{
"type": "featured-product",
"name": "This one's Featured though",
"description: "yadda yadda"
}
]
例如,列表看起来像这样:
--------------
| |
| Featured |
| |
--------------
| || |
| Not || Not |
| || |
--------------
| || |
| Not || Not |
| || |
--------------
| |
| Featured |
| |
--------------
| || |
| Not || Not |
| || |
--------------
| || |
| Not || Not |
| || |
--------------
然而,对于FlatList
组件,我没有运气实现这个设计的布局。
flex: 1
添加样式,在双列上为flex: 0.5
添加样式不允许包装列并始终显示单个列行numColumns
道具设置为2可以稍微正确地显示产品,但会导致全宽特色项目出现问题。我冒险尝试使用FlatList获得性能优势,但我开始认为它可能不适合我需要的布局。
有没有人解决过这个问题?

据我所知,FlatList在自己的行中呈现数据中的每个项目。除非您操纵本机端以创建所需的行为组件,否则您所要求的行为是不可能的。
我认为你最好/最简单的方法是第三种选择。你可以做什么我想以某种方式操纵你正在渲染的数据,并将所有其他“非特色”项目分成两部分并将它们一起渲染。
例如
renderItem({item}) {
if (item.notFeatured === true) return <NotFeaturedRow data={item.items} />
else return <FeaturedRow data={item} />
}
const data = [
{
"type": "featured-product",
"name": "Product",
"description: "yadda yadda"
},
{
notFeatured: true,
items: [
{
"type": "product",
"name": "Another Product",
"description: "yadda yadda"
},
{
"type": "product",
"name": "And Another Product",
"description: "yadda yadda"
}
]
},
{
notFeatured: true,
items: [
{
"type": "product",
"name": "Another Product",
"description: "yadda yadda"
},
{
"type": "product",
"name": "And Another Product",
"description: "yadda yadda"
}
]
},
{
"type": "featured-product",
"name": "This one's Featured though",
"description: "yadda yadda"
}
]

只需使用RecyclerListView即可。它比FlatList更快,并且在Flipkart进行了战斗测试。它支持交错布局。
