ImageButton Src&background Properties

ImageButton is a button control with an icon, with the SRC attribute, which is the setting of his icon, as well as a public property of all the controls background, which can also be set to its "icon".

In fact, SRC is the set icon, and background just sets the background. If the size of the control is 100*100 picture resource is 80*80, then with SRC, the picture will be centered, if you use background then the picture will be stretched filled with the control. Importantly, background is the underlying picture resource, SRC is a resource that covers the background above, and they can be used overlay to achieve the selected effect. Used in the Activitygroup
