请告诉我他们如何在react-native中呈现SVG文件（0.49）。提前谢谢。

我尝试使用此库：https://github.com/matc4/react-native-svg-uri

但这不起作用。细节错误：https://anotepad.com/notes/d2itr5

使用此react-native-svg

有关详情，请参阅此视频： https://www.youtube.com/watch?v=TdkzJkrHCgQ

这是解决方法：

<强> index.js

import React, {Component} from 'react';
import{
  AppRegistry,
  StyleSheet
} from 'react-native';

import Pin from './classes/pin';

export default class MainPage extends Component {
  render(){
    return (
      <Pin />
    );
  }
}
AppRegistry.registerComponent('demo1', ()=> MainPage);

<强> Pin.js

import React, {Component} from 'react';

import {
  StyleSheet,
  View,
  Text,
  AppRegistry
} from 'react-native';



import Back from '../icons/back.js';
import Deliver from '../icons/deliver.js';
import Heart from '../icons/heart.js';
import Elipse from '../icons/elipse.js';
import Thumbtack from '../icons/thumbtack.js';

export default class Pin extends Component{
    render(){
      return(
        <View style={styles.PinContainer}>
          <View style={styles.PinHeader}>
              <View style={styles.HeaderUitility}>
                <Back />
                <Heart />
                <Deliver />
                <Elipse />
              </View>

              <View style={styles.HeaderPinButtonContainer}>
                <View style={styles.PinButton}>
                  <Thumbtack style={styles.Pinpin}/>
                  <Text style={styles.PinText}>SAVE</Text>
                </View>
              </View>
          </View>
          <View style={styles.PinMiddle}>

          </View>

          <View style={styles.PinFooter}>

          </View>
        </View>
      )
    }
}

const styles = StyleSheet.create({
  PinContainer:{
    flex: 1,
    alignSelf: 'stretch',
    backgroundColor: '#cecece'
  },

  PinHeader:{
    flexDirection: 'row',
    backgroundColor: 'white',
    alignItems: 'flex-end',
    justifyContent: 'space-between',
    height: 56,
    padding: 8,
    paddingBottom: 12
  },

  HeaderUitility:{
    flex: 1,
    flexDirection: 'row',
    justifyContent: 'space-between'
  },

  PinButton: {
    flexDirection: 'row',
    backgroundColor: 'red',
    padding:8,
    borderRadius: 6,
    justifyContent: 'space-around',
    width: 70
  },

  HeaderPinButtonContainer:{
    flex: 1,
    alignItems: 'flex-end',
  },

  PinText:{
    color: 'white',
  }

})

SVG文件：

后退按钮：

import React, { Component } from 'react';
import Svg,{
    Circle,
    Ellipse,
    G,
    LinearGradient,
    RadialGradient,
    Line,
    Path,
    Polygon,
    Polyline,
    Rect,
    Symbol,
    Text,
    Use,
    Defs,
    Stop
} from 'react-native-svg';

export default class Back extends Component {
    render() {
        return (
            <Svg height="26.5" width="16">
            <Path d="M3.1,13.5c-0.3,0.3-0.3,0.3,0,0.5c0.3,0.3,11.5,11.5,11.5,11.5c0.5,0.5,0.5,1.2,0,1.7c-0.5,0.5-1.2,0.5-1.7,0

            </Svg>
        );
    }
}

发送图标：

import React, {Component} from 'react'; import Svg,{
    Circle,
    Ellipse,
    G,
    LinearGradient,
    RadialGradient,
    Line,
    Path,
    Polygon,
    Polyline,
    Rect,
    Symbol,
    Text,
    Use,
    Defs,
    Stop } from 'react-native-svg';

export default class Deliver extends Component {
    render() {
        return (
            <Svg height="26.5" width="32">
            <Path d="M29,0.6L2,13l9.3,4.4v8.8l8.1-5l7.4,3.5L29,0.6z

            </Svg>
        );
    } }

心脏图标：

import React, {Component} from 'react';
import Svg,{
    Circle,
    Ellipse,
    G,
    LinearGradient,
    RadialGradient,
    Line,

    Symbol,
    Text,
    Use,
    Defs,
    Stop
} from 'react-native-svg';

export default class Heart extends Component {
    render() {
        return (
            <Svg height="26.5" width="32">
            <Path d="M12.5,25.1c0.9,0.9,2.2,1.4,3.4,1.4c1.2,0,2.5-0.4,3.4-1.4l10.1-10c3.5-3.5,3.5-9.1,0-12.5
