android - 如何在 DialogFragment 中设置肯定/否定按钮？

Question

解决方案是 onCreatDialog。关于崩溃的另一个问题是由我的 listView xml 中的 LinearLayout parent 引起的

这里是我的代码[已编辑]:

public class MyDialogFragment extends DialogFragment {

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

        View mView = inflater.inflate(R.layout.fragment_dialog, null);
        ListView mListView = (ListView) mView.findViewById(R.id.lvListe);

        String[] mValues = {"Orientation", "Nombre de Chambres", "Nombre de Salle de bains", "Nombre de toilettes", "Cave", "Parking", "Garage", "Jardin"};

        getDialog().setTitle("Autres Critères");

        mListView.setAdapter(new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1, mValues));

        return mView;
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {

        return new AlertDialog.Builder(getActivity())
                .setPositiveButton("ok",
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog, int whichButton) {
                                }
                        }
                )
                .setNegativeButton("Cancel",
                        new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog, int whichButton) {
                                onCancel(dialog);
                            }
                        }
                )
                .create();
    }

}

请看一下DialogFragment的createDialog()方法。

这是一个例子:

@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) {
                        // DO SOMETHING
                    }
                }
            )
            .create();
}
