NullPointerException when using RelativeLayout as custom InfoWindow

Question

I\'m trying to use a RelativeLayout as custom InfoWindow for my markers, but a I get a NullPointerException every time showInfoW

Answer 1

I experienced this issue even when I didn't have a RelativeLayout in my xml. It turns out that my class backing the XML inherited from RelativeLayout, even though it was a LinearLayout.

It didn't cause a bug for several different devices, but when I tried on my S3 it crashed.

Anyways, just either remove or wrap the RelativeLayout or set a layout height/width first.

Answer 2

I had this problem and was able to fix it by adding

view.setLayoutParams(new ViewGroup.LayoutParams(desiredWidth,desiredHeight));

to the view before returning it from InfoWindowAdapter.getInfoWindow

Answer 3

Just found out that in android version < 4.4 this generates a nullpointer exception. Changing the layout with a Linear one will solve the problem.
