Question

What if I need the android:padding="120dip" to be different depending on screen size and I don’t want to create several other xmls?

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/right_back"
    android:orientation="horizontal"
    android:padding="120dip" >

As you want different value for one string resources – based on the different screens, you can create different values folder the same way we have drawable folders:

In all folder, create dimens.xml and make sure you will give the same variable name in every file but different value.

For example:

My dimens.xml in values folder is like:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <dimen name="padding_val">100dp</dimen>
</resources>

So now, you just need to mention android:padding="@dimen/padding_val".

But this is just for values folder, create the same dimens.xml file and put the value you want.
