Switch Switch组件 是一个跨平台通用的“开关”组件,在应用中很多时候会使用一个开关组件来控制某些功能是否开启;它提供的属性不多,value属性用来设置组件当前的值,onValueChange接收一个函数,当组件的值改变时调用此回调函数,回调函数的参数为组件新的值: class Index extends Component { constructor() { super();...
React Native Switch 最基本的使用,仅仅作为状态展示组件,那么只需要一个属性即可,那就是 value 用于设置开关的初始值。 App.js import React, { Component } from 'react' import { View, Text, Switch, StyleSheet } from 'react-native' ...
【Kevin Learn React Native】--> Switch 跨平台通用的“开关”组件。 注意这是一个“受控组件”(controlled component)。你必须使用onValueChange回调来更新value属性以响应用户的操作。如果不更新value属性,组件只会按一开始给定的value值来渲染且保持不变,看上去就像完全点不动。
