Pop-up not shown when used in a DrawerLayout/NavigationView

[HughJeffner]

I am using the spinner in the header layout of a NavigationView used in a DrawerLayout

When the app starts up everything works normally, but after selecting a navigation item in the NavigationView and re-opening the drawer the pop-up no longer shows when clicking on the spinner.

I traced back the problem to this line:

MaterialSpinner/library/src/main/java/com/jaredrummler/materialspinner/MaterialSpinner.java

Line 524 in 3dc38b5

isLaidOut = isLaidOut();

For some reason isLaidOut() returns false at that point socanShowPopup returns false. Not sure if this is some kind of interaction with the support libraries (I am using androidX) when running on newer API devices. I tested this on a few API levels and the problem seems to be happening on Nougat (API 24)+

As a work-around I added a listener to the drawer opened event and called requestLayout() on the spinner.

Yes In my case also, I am using Spinner inside a RecyclerView as a child, the specified issue occurred.
I have also use the solution suggested @HughJeffner and use requestLayout() in My ViewHolder when i initialise the Spinner, and it works fine.

Same problem here. Kinda gross to have to requestLayout in the ViewHolder, especially since the width and height are set correctly.
