Question

I’m creating a radial gradient like:

 <?xml version="1.0" encoding="utf-8"?>
 <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
 <gradient
      android:startColor="#7faacaFF"
      android:endColor="#cfe1edFF"
      android:gradientRadius="326"
      android:type="radial"/>
 </shape>

But in the gradientRadius field using values like sp and dip return an error.
Is there a way to specify the radius and scale for mdpi and scale it automatically in the rest of screen densities, or is necessary to create multiple drawable files?

Answer 1

So what if you do this:

res/drawable/foo.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
                                android:shape="rectangle">
 <gradient
      android:startColor="#7faacaFF"
      android:endColor="#cfe1edFF"
      android:gradientRadius="@dimen/radius"
      android:type="radial"/>
 </shape>

res/values-mdpi/dimens.xml

<resources ...>
...
<item name="radius" format="float" type="dimen">326</item>
....

</resources>

res/values-hdpi/dimens.xml

<resources ...>
...
<item name="radius" format="float" type="dimen">200.34</item>
....

</resources>

What do you think?
