android - Adding positive / negative Button to DialogFragment's Dialog

Question

I've already written a DialogFragment. Now I've realized that I want it to have a positive and a negative button just like an AlertDialog. How can I achieve such a thing while maintaining the code that I've written?

public class DoublePlayerChooser extends DialogFragment {
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);        

    setStyle(DialogFragment.STYLE_NORMAL,0);



}

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {

    return new AlertDialog.Builder(getActivity())
            .setTitle("title")
            .setPositiveButton("OK",
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int whichButton) {
                        // do something...
                    }
                }
            )
            .setNegativeButton("Cancel",
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int whichButton) {
                        dialog.dismiss();
                    }
                }
            )
            .create();
}



@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    View v = inflater.inflate(R.layout.doubleplayerchooser, container, false);
    getDialog().setTitle("Enter Players");

    firstPlayerPicker =  (ImageButton) v.findViewById(R.id.imageButton1);
    firstPlayerPicker.setOnClickListener(new OnClickListener() {
        public void onClick(final View v){

            callContactPicker(1);

        }       
    });

    secondPlayerPicker =  (ImageButton) v.findViewById(R.id.ImageButton01);
    secondPlayerPicker.setOnClickListener(new OnClickListener() {
        public void onClick(final View v){

            callContactPicker(2);

        }       
    });

    loadFromFile =  (ImageButton) v.findViewById(R.id.imageButton2);
    loadFromFile.setOnClickListener(new OnClickListener() {
        public void onClick(final View v){



        }       
    });

    firstTextfield =  (EditText) v.findViewById(R.id.editText1);
    secondTextfield =  (EditText) v.findViewById(R.id.EditText01);

    firstImage = (ImageView) v.findViewById(R.id.imageView1);
    secondImage = (ImageView) v.findViewById(R.id.ImageView01);



    return v;
}

Answer 1

This is how I figured it out. I erased the onCreateView and altered the onCreateDialog. This link actually had the answer so all the credit should go there. I've just posted it just in case anyone bumps in this question first.

    @Override
public Dialog onCreateDialog(Bundle savedInstanceState) {

    AlertDialog.Builder b=  new  AlertDialog.Builder(getActivity())
    .setTitle("Enter Players")
    .setPositiveButton("OK",
        new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int whichButton) {
                // do something...
            }
        }
    )
    .setNegativeButton("Cancel",
        new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int whichButton) {
                dialog.dismiss();
            }
        }
    );

    LayoutInflater i = getActivity().getLayoutInflater();

    View v = i.inflate(R.layout.doubleplayerchooser,null);

    firstPlayerPicker =  (ImageButton) v.findViewById(R.id.imageButton1);
    firstPlayerPicker.setOnClickListener(new OnClickListener() {
        public void onClick(final View v){

            callContactPicker(1);

        }       
    });

    secondPlayerPicker =  (ImageButton) v.findViewById(R.id.ImageButton01);
    secondPlayerPicker.setOnClickListener(new OnClickListener() {
        public void onClick(final View v){

            callContactPicker(2);

        }       
    });

    loadFromFile =  (ImageButton) v.findViewById(R.id.imageButton2);
    loadFromFile.setOnClickListener(new OnClickListener() {
        public void onClick(final View v){



        }       
    });

    firstTextfield =  (EditText) v.findViewById(R.id.editText1);
    secondTextfield =  (EditText) v.findViewById(R.id.EditText01);

    firstImage = (ImageView) v.findViewById(R.id.imageView1);
    secondImage = (ImageView) v.findViewById(R.id.ImageView01);


    b.setView(v);
    return b.create();
}
