    if (flag) {
        super.onBackPressed();

    } else {

                MainActivity.this);
        alert.setMessage("EXIT"); // Message
                                                                                // here

        alert.setPositiveButton("NO",
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog,
                            int whichButton) {

Remove finish(); default action is dismiss Put dialog.dismiss(); in side onClick method

Edit set flag = true;

boolean flag = false;

@Override
public void onBackPressed() {
if (flag) {
    super.onBackPressed();

} else {
    final AlertDialog.Builder alert = new AlertDialog.Builder(
            MainActivity.this);
    alert.setMessage("EXIT"); // Message
                                                                            // here

    alert.setPositiveButton("NO",
            new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog,
                        int whichButton) {
                    AlertDialog.Builder exitdialog = new AlertDialog.Builder(
                            MainActivity.this);
                    exitdialog
