How Do You Pass The Gravity Attribute Via Xml For A Custom View?

I'm trying to figure out how to pass android:gravity via xml for a custom view. The solution posted here (https://stackoverflow.com/a/3441986/413254) says to add the android:gravi

Solution 1:

by writing:

<attr format="integer" name="android:gravity"/>

you are intruducing the new attribute android:gravity with integer format, of course android:gravity is already defined in the system, so you need to change it into:

<attrname="android:gravity"/>
