How to make the android LayoutInflater use my Custom Resources

I have defined a custom class: `public class CustomResource extends Resources {}` in order to load custom external colors at runtime. This is working well in the Java code when using `getResources().getColor()`. When loading an XML layout via `setContentView()`, which contains references to colors, then `getColor()` of the CustomResources is never called when inflating XML resources. I already overrode `getResources` and `getSystemService` in the context but `getResources().getColor()` simply does not get called by the View constructors when they resolve XML attributes. It's because `obtainStyledAttributes()` from `Resource.Theme` is called from within the constructors of Widgets. I now have no idea what I have to additionally overwrite. Example: layout.xml contains a reference to drawable/button.xml, button.xml contains a reference to colors/somecolor. I now need the call from - for example - a `TextView` constructor (the inflater creates a TextView by calling the constructor with the xml attributes as parameters) which then calls `obtainStyledAttributes()` to use my resources class for resolving colors rather than the `TypedArray` magic that is currently happening in `obtainStyledAttributes()`.
