项目中,涉及到类似支付宝的应用增删模块,这几天简单的实现了下.
基本雏形实现了.后面的细节稍后再做处理.写篇博客记录下.

效果图:
editItem_resulut

实现思路 ==>
UI: 一开始采用外部ScrollView内部FlatList和ScrollView实现,后来发现有点臃肿,于是采用外部FlatList,内部ScrollView实现.然后发现其实代码差不太多…….浪费表情,其中依赖几个三方库:react-native-scrollable-tab-view,react-native-underline-tabbar.本来想使用SectionList实现的,但是感觉使用SectionList会更麻烦.
逻辑: 通过数据中 id 和 tag实现

废话不多缩,首先,新建一个项目,添加相应库:
第一种实现:
