Resume Alert Dialog state on Back button pressed

Resume Alert Dialog state on Back button pressed

I have to deal with Alert Dialog in my android app. In my first activity
there is one alert dialog.On particular action, alert dialog appears. When
user clicks yes button of Alert Dialog, user moves to second activity. In
my second activity, I have one button. On pressing of this button Alert
Dialog should be prompted again with same state. Is it possible to resume
the state of Alert Dialog on Back button pressed? code for dialog...
