<div> contains <img>,Can't display images

See original GitHub issue

“react-native”: “0.48.3” “react-native-htmlview”: “^0.12.0” android:7.0

here is my code:

render() {
    const htmlContent = `
        <div>
            <img src="http://d.lanrentuku.com/down/png/1504/bianping-yuanicon/bianping-yuanicon-09.png" />
        </div>
    `;
    return (
        <View>
            <HTMLView
                value={htmlContent}
            />
        </View>
    );
}

If use <div> containing < img>, will not be able to display the image.

You need to add another function named renderNode():

renderNode(node, index, siblings, parent, defaultRenderer) {
        if (node.name == 'img') {
            const a = node.attribs;
            return ( <Image style={{width: 300, height: 300}} source={{uri: a.src}}/> );
        }
    }

and then change HTMLView tag like this:

<HTMLView value={htmlContent} renderNode={this.renderNode} />

That’s all. Your renderNode() function and render() function should be siblings at that example. @Ctonys

Hello guys, this is my code. I hope it can help you

import HTMLView from 'react-native-htmlview';
import React, { Component } from 'react';
import { Image, Dimensions, PixelRatio } from 'react-native';

const { width } = Dimensions.get('window');

export default class HtmlView extends Component {
  renderNode(node, index, siblings, parent, defaultRenderer) {
    if (node.name == 'img') {
      const { src, height } = node.attribs;
      const imageHeight = height || 300;
      return (
        <Image
          key={index}
          style={{ width: width * PixelRatio.get(), height: imageHeight * PixelRatio.get() }}
          source={{ uri: src }} />
      );
    }
  }

  render() {
    return (
      <HTMLView
        value={`<html><body>${this.props.content}</body></html>`}
        renderNode={this.renderNode}
        stylesheet={this.props.stylesheet} />
    )
  }
}

PixelRatio.get() returns the device pixel density.
