Fixed layout error in HistoryListAdapter and restored roomrowlayout.
Added DragCrossSlider. With this a button can trigger on, by dragging up or down, and trigger off by dragging left or right.  Dragging diagonal will still trigger an individual amount.
Removing unused xml files.
Buttons are dynamical insert in the RoomActivity. The images/buttons are resized to match there place in the virtual gird which is defined in the Raum enum.
