Text Boxes Won't Apply Padding

When im creating the graphical user interface and apply padding (10dp) to the left and right sides of the email text box the padding dosent actually apply. Here are the current settings.

Code:
<EditText
android:id="@+id/editText1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:inputType="textEmailAddress"
android:paddingLeft="10dp" >
<requestFocus />
</EditText>

Basically i was the text box to fill the screen (width wise not the height) but have a 10dp gap on the left and right hand sides to make it look cleaner.
