android username password input

I need to accept values (username and password) from the user, when he clicks menu button and one of the button that says login. When the login button is clicked, a pop up should show up that accepts the values and should have an ok button. Expecting a pop something like when we try to download an 开发者_如何学JAVAapp from apple store (iphone) Could some one please guide me how to do this. Also... this menu is to be visible for a MapActivity class which implements LocationListener

thanks
