A subclass of Dialog that can display one, two or three buttons. If you only want to display a String in this dialog box, use the setMessage() method. If you want to display a more complex view, look up the FrameLayout called "custom" and add your view to it:

The AlertDialog class takes care of automatically setting

protected AlertDialog (Context context,

            boolean cancelable, 
            [DialogInterface.OnCancelListener](https://developer.android.com/reference/android/content/DialogInterface.OnCancelListener) cancelListener)

8 for you based on whether any views in the dialog return true from

protected AlertDialog (Context context,

            boolean cancelable, 
            [DialogInterface.OnCancelListener](https://developer.android.com/reference/android/content/DialogInterface.OnCancelListener) cancelListener)
