How do I reference android:gravity values in a resource file?

Concept:

 android:gravity="@integer/integer_name"

integers.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <integer
        name="integer_name"
        >1</integer>
</resources>

Gravity values are all integer constanst, you have to look it up and define it in your integers.xml .

Example implementation:

public static final int CENTER ... Constant Value: 17 (0x00000011)

in docs... Then you add to your integers.xml in res/values/:

 <integer
        name="center"
        >17</integer>

and in your xml, do:

android:gravity="@integer/center"

Here you go.

<integer name="gravity_bottom">80</integer>
<integer name="gravity_center">17</integer>
<integer name="gravity_center_horizontal">1</integer>
<integer name="gravity_center_vertical">16</integer>
<integer name="gravity_end">8388613</integer>
<integer name="gravity_left">3</integer>
<integer name="gravity_no_gravity">0</integer>
<integer name="gravity_right">5</integer>
<integer name="gravity_start">8388611</integer>
<integer name="gravity_top">48</integer>
