输出图像时View和ImageView的区别 [英] Difference between View and ImageView when outputting an image

问题描述

当我输出图像时，我使用 View:

When I output the image,I use View:

View.setbackgroundResource()

而不是 ImageView:

instead of ImageView:

ImageView.setImageDrawable(drawable)

我想知道是否有很大的不同?

I was wondering if there was a big difference?

推荐答案

当然有区别.

在第一个中，您正在修改某个视图的背景.在第二个中，您正在修改某个 ImageView 的 CONTENT(即图像).

In the first one, you are modifying the BACKGROUND of a certain View. In the second one, you are modifying the CONTENT (which is an Image) of a certain ImageView.

如果 ImageView 在另一个 View 内部(或上方)并且它们具有相同的大小，那么看起来可能是一样的，但通常它们是非常不同的.

It might seem the same thing if the ImageView is inside (or over) the other View and if they have the same size, but usually, they are very different.
