We use a different naming convention. Please see [here](https://github.com/Catrobat/Catroid/blob/master/catroid/res/layout/brick_change_y.xml#L38) for an example. These were refactored quite recently. But I also don't see that you use this `id` anywhere. Maybe you should check if you really need these `id`s. Same goes for the other layout files.

Unless something different was decided recently. @sjaindl @kaufi ?
