Im attempting to add a camera symbol at the bottom of my application (Like Snapchat) overlayering a map, but cant seem to make it work. The layer and the imagebutton within places itself below the layer containing the map object. If i reduce the hight of the "map-layer" it works, but then there is, naturaly, a white void on either side of the camera symbol which is centered.
Any suggestions? Here is a picture and the layout file, i included the whole thing in case i made some mistakes early on that causes the issue. All help is much appreciated.
