我想在我的反应本机项目的Appjs视图中导入它。
我尝试了很多方法,但它不起作用。我的意思是我想在我的视图中渲染它。如何在我的 Appjs 中导入和显示此文件。任何人都可以帮助我,这对我来说非常重要。
这是我的代码:
import ForwardRef from '../../constants/UI_login/Home_Landing_Page/BackgroundComponent'
import React from "react";
import Svg, { Defs, LinearGradient, Stop, Rect } from "react-native-svg";
/* Adobe XD React Exporter has dropped some elements not supported by react-native-svg: style */
const BackgroundComponent = ({ svgRef }) => (
<Svg width={375} height={247} viewBox="0 0 375 247" ref={svgRef}>
<Defs>
<LinearGradient
id="a"
x1={0.5}
y1={0.807}
x2={0.5}
y2={1}
gradientUnits="objectBoundingBox"
>
<Stop offset={0} stopColor="#fff" />
<Stop offset={1} stopColor="#fff" stopOpacity={0} />
</LinearGradient>
</Defs>
<Rect className="a" width={375} height={247} />
</Svg>
);
const ForwardRef = React.forwardRef((props, ref) => (
<BackgroundComponent svgRef={ref} {...props} />
));
export default ForwardRef;
应用.js
import React from 'react';
import { StyleSheet} from 'react-native';
//import {Actions} from 'react-native-router-flux';
import Routes from './components/Routes';
import {firebaseConfig} from "./constants/ApiKeys";
import ForwardRef from '../../constants/UI_login/Home_Landing_Page/BottomNavigationComponent'
import {AppContainer} from './components/Navigation'
import * as firebase from 'firebase';
if (!firebase.apps.length) { firebase.initializeApp(firebaseConfig); }
console.ignoredYellowBox = ['Setting a timer'];
export default class App extends React.Component {
render() {
return (
<AppContainer/>
<ForwardRef/>
);
}
}
现在我在那里得到一个黑色空白
您使用的是默认导出而不是命名导出,因此
import {ForwardRef} from "..."
你必须写
import ForwardRef from "..."
:)
请尝试执行以下操作:
- 打开
AppContainer
组件文件; - 在文件的头部添加
import
您的BackgroundComponent
组件; - 并将
<ForwardRef/>
添加到render return
