I'm dealing with a weird issue and I'm kind of lost about which direction to take:
I have a fragment which is opened from several places in the app(it shows an user profile). Most of the places it's ok but in one in particular it has a strange behavior, the first time it's open, most views are blank, but some like the profile picture and the toolbar title are ok, if I go back and enter it again then all the views are visible as expected.
I have tried several approached to solve this, one in particular is to call activity.recreate() in the fragment onCreateView() which makes the views visible but has some side effects that I want to avoid and also is just a patch and not dealing directly with the problem.
Now, the most strange part to me is that if I open the screen in the layout inspector I see this:
As you can see the textviews and other elements are set, but just not visible.
One experiment I tried was giving a textview a fixed width and in that case it is visible, could this be some problem with the constraintLayout?
Any other ideas?
Thanks in advance!
EDIT:
One other thing, could the viewstubs have anything to do here?
