Storing dimensions in xml file in Android

Question

I am trying to consistently use the same dimension in all the views in my android app (e.g., a left margin of 20dp). If I were using HTML, I would simply use a CSS file, but

Answer 1

You can use styles (res/values). This article will be a good start.

Answer 2

Create a file called res/values/dimens.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <dimen name="icon_width">55dip</dimen>
    <dimen name="icon_height">55dip</dimen>
    <dimen name="photo_width">170dip</dimen>
    <dimen name="photo_height">155dip</dimen>
</resources>

Then reference them in your other xml:

android:padding="@dimen/icon_width">
