Larger font for tablet

[WingedToaster]

Is there a way to increase the size of the font? I'm on a tablet and it seems too small.

Adding style="@style/TextAppearance.AppCompat.Headline" to the layout XML gets me half the way there, the help messages are still pretty small.

i edit by find view id like this
creditCardForm.findViewById(R.id.cc_form_layout).getLayoutParams().height= ViewGroup.LayoutParams.MATCH_PARENT;
