android - What is the difference between src and background of ImageView

Question

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

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

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

Answer 1

All views can take a background image.

The src to an ImageView has additional features:

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

And more that you may find in the docs.
