How to reduce EditText
Hint size?
You can set simple HTML attributes to the hint string itself.
See accepted answer here: Android EditText hint
EDIT: just played with it myself, this worked for me:
view.setHint(Html.fromHtml("" +
getString(R.string.hint) + ""));
This is a list of tags accepted by fromHtml: http://commonsware.com/blog/Android/2010/05/26/html-tags-supported-by-textview.html (though didn't work for me)
