presenting a list of choices in a dialog task 1

I don't understand what it means but here is my code:

import android.app.Activity; import android.app.AlertDialog; import android.app.AlertDialog.Builder; import android.content.DialogInterface; import android.content.DialogInterface.OnClickListener; import android.view.MenuItem;

public class MainActivity extends Activity {

protected DialogInterface.OnClickListener mDialogListener = new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int which) {


// Some code omitted!

public boolean onOptionsItemSelected(MenuItem item) {
    int itemId = item.getItemId();

    switch(itemId) {        
        case R.id.action_button:

    return super.onOptionsItemSelected(item);
  AlertDialog.Builder builder = new AlertDialog.Builder(this);
