Strange problem! I have a layout with two rows of buttons at the bottom. The last row (4 buttons) works without problems but the large button "btnLatLon" with the label "Label5" on top works only after tapping x times on the screen, especially at the bottom of the button there is a chance, so that I hit the buttons below also. I hope this was understandable. Enclosed the layout and the layout definitions. Of course the button btnLatLon is defined and there is a "Sub btnLatLon_Click" in the code. (The buttons are imageviews with a label on top). When i remove all the layout code the two rows of buttons are in the middle and not button works.
I supposed this too although the 4 buttons below worked nevertheless there were also labels on it. But I tested this inserting a new sub procedure "Sub Label5_Click". This worked neither.
You were right! I had in the code additionally to the designer code this line: "Activity.AddView(LVDb, 0, 150, 95%x, 80%y)". This caused that the button was covered for 90%. Thanks!
