react-native-tree-select:树结构选择组件
请注意,在组件中使用了图片组件react-native-vector-icons的依赖,使用时,请添加该依赖项。 引用位置和方式如下:
import Ionicons from 'react-native-vector-icons/Ionicons';
--components: treeSelect组件
--example: 组件演示代码
--.gitignore:git忽略文件
--README.md:说明文档
首先能够通过如下命令进行安装
npm i react-native-tree-select
然后通过下面命令进行导入:
import TreeSelect from 'react-native-tree-select';
如下代码是简单的使用
import TreeSelect from 'react-native-tree-select';
...
render() {
return (
<TreeSelect
data={treeselectData}
// isOpen
// openIds={['A01']}
defaultSelectedId={['B062']}
isShowTreeId={false}
// selectType="single"
selectType="multiple"
itemStyle={{
// backgroudColor: '#8bb0ee',
fontSize: 12,
color: '#995962'
}}
selectedItemStyle={{
backgroudColor: '#f7edca',
fontSize: 16,
color: '#171e99'
}}
onClick={this._onClick}
onClickLeaf={this._onClickLeaf}
treeNodeStyle={{
// openIcon: <Icon size={18} color="#171e99" style={{ marginRight: 10 }} name="ios-arrow-down" />,
// closeIcon: <Icon size={18} color="#171e99" style={{ marginRight: 10 }} name="ios-arrow-forward" />
openIcon: <Image
resizeMode="stretch"
style={{ width: 18, height: 18 }}
source={require('./images/down-circle.png')} />,
closeIcon: <Image
resizeMode="stretch"
style={{ width: 18, height: 18 }}
source={require('./images/right-circle.png')} />
}}
/>
);
}
注意:数据结构如下面形式:
[
{
"id":"A",
"name":"农、林、牧、渔业",
"sortNo":"A",
"parentId":"0",
"children": [
{
"id":"A01",
