What is the difference between findViewById(R.id.content) and getRootView() ? Don’t both return the root view of an activity?
The method
findViewById(R.id.content)searches down the view hierarchy for a View with the idcontent(it examines itself as well).The method
getRootView()walks up view hierarchy until it hits the root View (it examines itself as well).If the View you are in has the id
contentand it is the root view then these methods will give the same result, otherwise they won’t.
