三、Example usage:

3.1 基本用法

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')} />
            }}
          />
    );
  }
