There are many kind of Dialogs in Android. Please take a look at Dialogs. I guess what you are looking for is something like AlertDialog . This is the example of how you can implement on BackPress button.

@Override
public void onBackPressed() {
    AlertDialog.Builder alert = new AlertDialog.Builder(this);
    alert.setTitle("Do you want to logout?");
    // alert.setMessage("Message");

    alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int whichButton) {
            //Your action here
        }
    });

    alert.setNegativeButton("Cancel",
        new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int whichButton) {
            }
        });

    alert.show();

}
