示例

普通示例

import {createElement, render} from 'rax';
import DU from 'driver-universal';
import Image from '../src/index';

const App = () => {
  const imageRef = useRef(null);
  return (
    <Image
      ref={imageRef}
      source={{
        uri: 'https://gw.alicdn.com/tfs/TB1bBD0zCzqK1RjSZFpXXakSXXa-68-67.png',
      }}
      style={{
        height: '68',
        width: '67'
      }}
   />
  );
};

render(<App />, document.body, { driver: DU });

使用fallbackSource和resizeMode

import {createElement, render} from 'rax';
import DU from 'driver-universal';
import Image from '../src/index';

const App = () => {
  return (
    <Image
      source={{
        uri: 'https://gw.alicdn.com/tfs/TB1g6AvPVXXXXa7XpXXXXXXXXXX-215-215.png'
      }}
      fallbackSource={{
        uri: 'https://gw.alicdn.com/tps/i3/TB1yeWeIFXXXXX5XFXXuAZJYXXX-210-210.png_70x70.jpg'
      }}
      style={{
        width: 100,
        height: 100,
      }}
      resizeMode="cover"
    />
  );
};

render(<App />, document.body, { driver: DU });
