How to programmatically retrieve custom theme values ​​via Robolectric

I can access custom color theme values ​​in my application via:

private int getTextColorFromTheme(int textAppearanceAttrResId, int state) {
    TypedValue typedValue = new TypedValue();

>>>>/* missing TypedValue.data in Robolectric!! */
    Resources.Theme theme = mContext.getTheme();

    // textAppearanceAttrResId is a reference, so it is required to be retrieved this way.
    theme.resolveAttribute(textAppearanceAttrResId, typedValue, true);

    int[] textColorAttr = new int[]{android.R.attr.textColor};
    int indexOfAttrTextColor = 0;
    TypedArray a = mContext.obtainStyledAttributes(typedValue.data, textColorAttr);
    ColorStateList csl = a.getColorStateList(indexOfAttrTextColor);

>>>>/* NPE thrown here in Robolectric! */
    int color = csl.getColorForState(new int[]{state}, -1);

    a.recycle();

    return color;
}

      

        
        
        
      

    

But Robolectric throws NPE when trying to access ColorStateList. I noticed that mContext.getTheme () returns a theme with a TypedArray whose data is 0.

mContext is configured earlier in setup ():

    ActivityController<MyActivity> activityController = Robolectric.buildActivity(MyActivity.class).attach();
    MyActivity activity = activityController.get();

    activity.setTheme(com.sudocoder.android.theme.R.style.Theme_Mine);
    activityController.create().start().resume().visible();

    mContext = activity;
