Http://www.androidren.com/index.php? Qa = 301 & qa_1 = differences between android-src and android-background in android imageview

There are several differences:

1. src is the foreground. Background is the background.

2. src is the display content, and background is the background.

3. background is an attribute of all views, while src is unique to ImageView. It is affected by android: scaleType, and the background is always scaled to the view size.

 

Appendix: More detailed scaleType description:

CENTER/center displays images in the view CENTER without scaling

CENTER_CROP/centerCrop scales the image proportionally so that the image length (width) is greater than or equal to the corresponding dimension of the view.

CENTER_INSIDE/centerInside scales the image proportionally so that the image length (width) is smaller than or equal to the corresponding dimension of the view.

FIT_CENTER/fitCenter scales the image proportionally to the smallest side of the view and is displayed in the center.

FIT_END/fitEnd scales the image proportionally to the smallest side of the view, which is displayed in the lower part of the view.

FIT_START/fitStart scales up or down an image proportionally to the smallest side of the view, which is displayed on the top of the view.

FIT_XY/fitXY: scale the image out of proportion to the view size.
