在React Native中导出方法/功能

Question

export { width as responsiveHeight } from "react-native-responsive-dimensions";

我想导出名称为width responsiveHeight width 。 正确的方法是什么？ 由于这是行不通的。

Answer 1

您的语法相反。 您想获得width responsiveHeight width 。

尝试这个

export { responsiveHeight as width } from "react-native-responsive-dimensions";

Answer 2

实际上，您在做相反的事情，您正在使用width函数，并为其添加了一个名为sensitiveHeight的别名，因此您需要执行以下操作：

export { responsiveHeight } from "react-native-responsive-dimensions";

就这么简单，以这种方式导出宽度，它应该没有问题。

Answer 3

试试这个。

import React from "react";
import {responsive} from "react-native-responsive-ui";

@responsive
export default class Debug extends React.Component {
    render() {
        const {width, height} = this.props.window;
        console.log(`New window dimensions: ${width}x${height}`);
        return null;
    }
}
