一个具有搜索和自动完成（typeahead）功能的React Native的下拉项目选择器。
如何使用它
1.安装
# Yarn $ yarn add react-native-autocomplete-dropdown # NPM $ npm i react-native-autocomplete-dropdown
2.导入自动完成的下拉组件
import { AutocompleteDropdown } from 'react-native-autocomplete-dropdown';
3.基本使用方法
const [selectedItem, setSelectedItem] = useState(null);
<AutocompleteDropdown
clearOnFocus={false}
closeOnBlur={true}
closeOnSubmit={false}
initialValue={{ id: '2' }} // or just '2'
onSelectItem={setSelectedItem}
dataSet={[
{ id: '1', title: 'Alpha' },
{ id: '2', title: 'Beta' },
{ id: '3', title: 'Gamma' },
]}
/>;
4.数据集应该是一个JS对象或数组
如下所示
[
{ id: "1", title: "Alpha" },
{ id: "2", title: "Beta" },
{ id: "3", title: "Gamma" }
]
