How to reduce EditText
Hint size?
You can do it by setting a size in the string recource.
For example:
<string name="edittext_hint"><font size="15">Hint here!</font></string>
then in your XML just write
android:hint="@string/edittext_hint"
This will resault in a smaller text for the hint but the original size for the input text.
