Venkata, All you probably need is an activity. May be just the activity that you are on when the menu is clicked.
Eitherway on the menu click start an asynctask and you can show the progress bar while the asynctask is in progress. At the end of that asynctask you can update the view in your activity with the data. Or you can start a new actvity first and have that new activity start an async task.
