Android Question Remove Multiple Circles from Google Maps

rscheel · May 20, 2021

Hello, I need to add multiple circles in google maps and in the same way to be able to remove them all, so far I can add them, but I can't delete them, they keep drawing on themselves

Add Circles:

Dim Circle1 As Circle
Circle1 = gmapExtra.AddCircle(gmap, co)

Remove circles:

Circle1.Remove

thanks for your help.

save the circles to a list and then you have the references to delete them.

for example.

B4X:

'Global definition
Dim MyCircles as list

'initialisation
MyCircles.initialize

'... Your code...
Dim Circle1 As Circle
Circle1 = gmapExtra.AddCircle(gmap, co)
MyCircles.add(Curcle1)


' Later...
private sub Removeallcircles
for each c as circle in MyCircles
    c.remove
next
end sub
