what is the different between view and activity in android development?
<p>when i need to create a new activity and when i need to change the view?</p>

<p>my app need to do:</p>

<h2>screen #1</h2>

<p>two big buttons(sort of menu)</p>

<h2>screen #2</h2>

<p>list of items - depend on the selection on prev screen</p>

<h2>screen #3</h2>

<p>another list - depend on the selection on prev screen</p>

<h2>screen #4</h2>

<p>show item </p>

<p>all screens need to have the same menu menu (the last has another button)</p>

<p>do i need to create an activity for each screen or just change the view in the same activity?</p>

<p>maybe i need to create a parent class (myBase) that will extend activity and all my acitivities will extend him?</p>
