Some differences between ImageView attributes Src and background in Android

Clear points:

1, src refers to the picture want to display the content, is your concern point
2, background refers to the background of the picture, is not generally concerned about the point

For example: A poster affixed to a wall, then SRC is this poster, the back of the wall is background

3, ImageView call in the Setimagexxx () method, set the picture is set SRC, want to set the background please use the SetBackground () method.

Therefore, the general need to transform the content, will be set to src

4, setting the Margine and padding values for the SRC and background effect is not the same.

Margine : Refers to the distance the control is to the parent control, affecting the distance between the background and the parent container.

padding: Refers to the distance between the contents of this control and the bounds of this control, affecting the distance between the SRC and background boundaries
