Android (Java): Is there an event or somethingelse that simply telling me that all GUI elements of an...
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
If I try to use, for example, the getHeight() method of a LinearLayout object before it is rendered I get a 0. The same happens for every gui element if they are not ready. Perhaps I make a mistake but for solving this problem I use a ViewTreeObserver object and OnGlobalLayoutListener for every GUI element for being sure that a GUI element is ready before getting some infos from it . What I’d like to know if is there an event or other stuff that in a very simple way tells me if the entire GUI of an Activity is completely rendered and ready to use. When I used Appcelerator Titanium there was an event able to say that (I don't remember the exact name). What i read on Android, run code only after the UI has been rendered for an activity I don't know how to apply simply to my question.

What if you use anOnGlobalLayoutListenerfor the root view of your activity? For the root to be ready, all its children have to be ready as well.
