In Android, is it possible to include a custom property in a style?

Question

In my Android project I have a custom view with a custom property. Setting the property works fine:

<com.mycompany.CustomView
    [...]
    mycompany:myproperty="myvalue"
/>

What I want to do is set the property in a style, so that I have a style like this:

<style name="CustomViewStyle">
    <item name="mycompany:myproperty">myvalue</item>
</style>

And change the custom view declaration to this:

<com.mycompany.CustomView
    [...]
    style="@style/CustomViewStyle"
/>

However, this results in the build error No resource found that matches the given name: attr 'mycompany:myproperty'. Adding the namespace declaration xmlns:mycompany="http://schemas.android.com/apk/res-auto" to style.xml does not help. Is there a way to make this work?

I believe you should set your custom style like this

<style name="CustomViewStyle">
    <item name="myproperty">myvalue</item>
</style>

I have done this. As I wrote in my question, setting the style on the actual element works fine, it's when I try to set it in a style that I have a problem.

I am sorry that I misunderstood before. Updating my answer.

Perfect, that works! Don't know why I didn't try that.
