Créer un DIalogFragment

Bonjour
Voici le code créer un DIalogFragment sous Android:

public class MyDialogFragment extends DialogFragment {
public static MyDialogFragment newInstance(int title) {
MyDialogFragment dialog = new MyDialogFragment();
Bundle args = new Bundle();
args.putInt("title", title);
dialog.setArguments(args);
return dialog;
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_dialog, container, false);

Button button = (Button) v.findViewById(R.id.buttonShow);
button.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
((DialogActivity) getActivity())
.showDialogType(DialogActivity.TYPE_ALERT_DIALOG);
}
});

getDialog().setTitle(getArguments().getInt("title"));

return v;
}
}
