Hi, I find really hard to imagine that there's no way to know the actual Views' size before they are displayed.
I was expecting a sort of callback method on the Activity class or any listener on the View (or ViewGroup) to be implemeted so that I can get the size of UI components. Anyway, I found a sort of workaround which in the onCreate method of an Activity, I'll get a reference to the Display object thorugh the WindowManager display = this.getWindowManager().getDefaultDisplay(); Once I got the display, I can get the width and height of it and with that I can tweak some settings of some animations I want to apply on some UI components. Ideally, a callback method on the Activity which allows to know the actual size of UI components just before they are displayed would be preferred.
