How to set attribute colors on a custom keyboard?

Question

I'm trying to make my custom keyboard to change his colors according to the current theme in project, but it fails, this is my code:

<?xml version="1.0" encoding="UTF-8"?>
    <android.inputmethodservice.KeyboardView
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/keyboard"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:keyBackground = "@drawable/keybackground"
        android:keyTextColor="?attr/colorPrimary"
        android:background="?attr/android:colorBackground"
        android:keyTextSize="22sp"/>

When I put regular colors everything works fine! How can I do it flexible?

I'm not sure this is what you are looking for but you could try using the res-auto namespace:

<android.inputmethodservice.KeyboardView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:custom="http://schemas.android.com/apk/res-auto"
    android:id="@+id/keyboard"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    custom:keyBackground = "@drawable/keybackground"
    custom:keyTextColor="?attr/colorPrimary"
    android:background="?attr/android:colorBackground"
    custom:keyTextSize="22sp"/>

If you are looking for changing it dynamically while the app is running I think the linked answer is the way to go. Things that should be changed dynamically is preferably done in code while static design preferably is done in xml.
