I see there is a background band on the wooble menu. I have a color for the menu itself but the background (the half upper part) changing on the background to transparent does not cause change.... I want to have the wooble menu over a google maps (it is pure visual)

is it possible?
Sorry didn't understand. The upper half is transparent by default. Post a small screenshot of that menu area. And explain what is the problem.

See the red box... I cant get rid of that area in b4a and b4i

the map is going under, changing the background color to transparent does nothing... changing the activity background color on the layout does change this area, but that does not solve the map thing.

Maybe your layout is wrong. Maybe you have placed the wobble menu right after the map view so the map view's bottom is the top of the wobble menu.

Half of the wobble menu view has the shadow and the selected icon view with a transparent background and the other half has the bottom part.

So increase the map view height. New height = Current height + (wobble menu height / 2)

I think it will solve the issue.

The map is already under the wobblemenu.... so if it is transparent is should be showing it , if you see to the left there is a small portion of the map right there

When I try to run the example, I encountered the following error:

Error occurred on line: 94 (WobbleMenu)
java.lang.NumberFormatException: For input string: "null"
at sun.misc.FloatingDecimal.readJavaFormatString(FloatingDecimal.java:2043)
at sun.misc.FloatingDecimal.parseDouble(FloatingDecimal.java:110)

at anywheresoftware.b4a.BA.ObjectToNumber(BA.java:684)
at b4a.example.wobblemenu._designercreateview(wobblemenu.java:1095)


I fixed it by open the layout designer and set the corner radius to value other than 0.

I faced the same Issue. I just open the designer and save the layout without any changes and then run. It successfully worked.
