Android :: How Do I Get Some Padding Around My Checkbox

I have a horizontal LinearLayout. This LinearLayout has a checkbox next to another LinearLayout. The layout width/height of the checkbox is wrap_content, whereas the inner LinearLayout is fill_parent/wrap_content. The layout_weight of the inner LinearLayout is set to 1.

I've tried to add some android:padding around the checkbox to give some space around it, but no padding is given. I've also tried android:paddingLeft/Right/etc. How do I get some padding around my checkbox?

Note: I have an inner LinearLayout because I will be adding more TextViews
