In my application I have three buttons that are to be part of each and
every activity. These button are independent of each other and on
click do mutually exclusive things(say launch different activity).
So, in my layout XML for every screen I have a <LinearLayout><Button/
><Button/><Button/></LinearLayout> element.

As I understand, at run time, if there are 5 screens, the number of
Button objects created would be 5 x 3 = 15.Assuming that all the five
activities are on stack.

However, If i create a custom view and have these three Buttons as its
static members and then add this custom view in layouts of every
screen, at runtime, I will have just 3 Button Objects. However, these
three instances being static will last longer.

Which amongs the two approaches mentioned is better and perhaps
advisable?

Thanks.
