I'm currently learning Android Studio, and am just a beginner, so forgive me if I'm doing something wrong. Options are not being displayed in the drop down menu, for example, if I add a new ImageView, the layout_width's dropdown options show both match_constraint and wrap_content - however, match_parent is missing. I have to manually type in match_ parent, upon which it begins working properly. Also, the autocomplete is not working properly, and it used to work until a couple of days ago. For example, if I wanted findViewById, I just have to search find, and a list of dropdown options would have appeared, from which I can select. That too has gone missing. Any tips?
