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" }
]
