Button Size?

Using android why do I get 2 different sizes of buttons as shown below? Can the size and position of the widgets be manipulated?

Yes to both. If you do a long press on the widget (in design mode) it will indicate it’s ready for resizing, just drag to your required size. Same for all the other resizable widgets.

To re-position just drag and drop.
