ImageView的src和背景有什么区别 [英] What is the difference between src and background of ImageView

问题描述

我对将 src 或 background 用于 ImageView 感到困惑.

I am a puzzled about using src or background for an ImageView.

我知道前者是指这个ImageView的内容，后者是指ImageView的背景.

I know the former means the content of this ImageView and the latter means the background of the ImageView.

但是如何决定使用哪一个呢?我看不出有什么区别.

But how to decide which one to use? I don't see the difference.

推荐答案

所有视图都可以带背景图片.

All views can take a background image.

src 到 ImageView 具有附加功能:

The src to an ImageView has additional features:

• 不同的缩放类型
• adjustViewBounds 用于设置边界以匹配图像尺寸
• 一些转换，例如 alpha 设置

• different scaling types
• adjustViewBounds for setting bounds to match image dimensions
• some transformations such as alpha-setting
