设计思路

基础组件,用于展示图片。

** 注意,在 native 端,图片必须声明宽高, 或通过 flex:1 等方式具备宽高,才能绘制,否则无法展现。**

API

属性配置说明类型默认值
src新增,与 source api 含义相同string
style必须写宽高,或通过 flex:1 等能力具备宽高占位,否则无法渲染object
resizeMode组件尺寸和图片尺寸不成比例的时候如何调整图片的大小枚举类型,可选 contain cover stretchstretch
onLoad图片 onLoad 方法,其中 e.size 可返回图片真实宽高function(e)

src

  • 图片 url

    • 建议使用 https 协议。
    • 建议不要使用相对路径。
    • 开发阶段,您如果需要任意尺寸图片,可以使用 placeholder 占位符服务, 如:
<Image
  src="https://via.placeholder.com/350x150"
  style={{ width: 350, height: 150 }}
/>
  • resizeMode 释义
    • contain : 包含,在区域内图片完全展示,不拉伸,不裁剪
    • cover : 覆盖,覆盖整个区域,可能图片本身会被部分被挡住而不显示,等比缩放,可能会裁剪
    • stretch : 拉伸,拉伸图片以撑满整个区域

例:

<View style={{ width: 600, height: 400 }}>
  <Image
    style={{ flex: 1 }}
    src="https://gd2.alicdn.com/imgextra/i2/413996455/TB2tNcJbd0opuFjSZFxXXaDNVXa_!!413996455.jpg"
  />
