            .setMessage("Message")
            .setPositiveButton("OK",new DialogInterface.OnClickListener(){
                public void onClick(DialogInterface dialog, int which) {
                    // continue
                }
            })
            .setNegativeButton("Cancel", new DialogInterface.OnClickListener(){
                public void onClick(DialogInterface dialog, int which){
                    // do nothing
                }
            })
            .setIcon(android.R.drawable.ic_dialog_alert)
            .show();
