Here is an example. For some reason there seems to be implicit padding in the button. I tried setting padding, minWidth, and minHeight to 0dp in the root level RelativeLayout but for some reason the padding still persists. I also tried putting these attributes in each subview like all the buttons and TextViews but still nothing. Any idea what's going on here?

There seems to be top and bottom padding on my TextViews as well:
EDIT:
Anand Singh mentioned dimens.xml in the comments. I actually have no idea what this resource does and decided to check it out. Here's the code:
<resources>
<!-- Default screen margins, per the Android Design guidelines. -->
<dimen name="activity_horizontal_margin">16dp</dimen>
<dimen name="activity_vertical_margin">16dp</dimen>
</resources>
However, I never reference this in my layout so I don't understand how its being used? Moreover, even when I comment out these stylings in the dimens.xml file, I still get the same padding problem.
