how to access button/view of an activity from another activity
<p>I have a button in an Activity and when on clicking this button, some operation will be performed in another activity. And I should call the buttonclick event in 2nd activity only.Simple saying, I have a TabActivity with button and upon clicking the button some operation should be performed  in the underlying tabs. ButtonClick event should be in the tab.</p>

<p>How can I achieve this?</p>
