如何在React Native中的布尔数组中初始化false的默认值以及如何更新状态布尔数组变量

Question

强文本 Android屏幕

import React,{ Component} from 'react';
import { Text, View, Button, TouchableOpacity,SafeAreaView } from 'react-native';

const arr = [ { `enter code here`image: require('../../../assets/account.png'),
name: 'Super Admin'},        
                  { `enter code here`image: require('../../../assets/account.png'),
name: 'Admin'},
                  {  `enter code here`image: require('../../../assets/account.png'),
name: 'Customer' }  
                ]


export default Users extends Component {

state = {
    isGetOnceButtonClicked: []
}

doAddItems = (item,index) => {                  
    this.setState({isGetOnceButtonClicked[index]: !this.state.isGetOnceButtonClicked[index]});      
}

render(){
    const {navigate} = this.props.navigation;        
    return(

        <View > 
            {arr.map((eachItem,index) =>                                 
                <View style = {{flex:1, marginTop:10, flexDirection: 'row', justifyContent: 'space-between' , borderBottomWidth:0.5, bordercolor:"#ddd", alignItems: 'stretch'}}>
                    <View>
                        <Image 
                            style={{width: 50, height: 50 }}
                            source={ eachItem.image }
                        />
                    </View>
                    <View style = {{  }}>
                        <Text>{ eachItem.name }</Text>

                    <View >                                                        
                        { this.state.isGetOnceButtonClicked ? <InputNumberSpinner /> : <Button 
                            type = "clear"
                            title="Continue"
                            onPress={this.doAddItems.bind(this,eachItem,index)}                               
                            />     
                        }
                    </View>                                                                                       
                </View>                                                                                          
            )}                    
        </View>                         
    );

如何在React Native的布尔数组中初始化false的默认值，以及如何在每次单击其对应元素时更新状态布尔数组的变量？

UI显示如上图所示，链接名称为“ Android屏幕”，每当单击相应行时，i sButtonClicked [index] = false的行状态应更新为true，然后自动将自定义组件动态获取到相应行，以代替“继续”按钮。 谁能帮我解决这个问题。 我尝试了很多解决方案，但没有一个起作用。
