Static member views in activity - Android

Question

In each of the activities in my application, all the views (grids/lists/buttons... lots of them) are declared as static members of the activity. Is this good practice or is

Answer 1

Personally I'd avoid using static variables as these variables are kept within memory, even though the activity may no longer require them.

The UI components don't really need to be static as they should be retrieved from the onCreate using the findViewById, or created programatically in the onCreate and there is no need to store the variable permanently.
