When I use dismiss to remove a popup window, does it only hide it

  • 0

When I use dismiss to remove a popup window, does it only hide it or removes it from memory?

I tried dismiss, then showAtLocation several times (using the same PopupWindw object, not re-creating it) and the window was displayed and hidden without problems. The question is can I count on it – perhaps it is marked for deletion by the GC, but hasn’t been garbage-collected yet?

Thanks.

    dismiss() is opposite to showAtLocation(), the object remains in a valid state after dismiss(). So it is safe to toggle dismiss()/showAtLocation()

    It can be seen from the Android source code in here – you can look at dismiss() and showAtLocation() implementations
