Deactivate menu item in Dialog

Question

I am using a DialogFragment to display a list of menu items in the dialog by setting the items based on a string array.

public class MenuDialogFragment extends 

    private Menu mMenu;

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
        builder.setTitle(R.string.dialog_title)
                .setItems(R.array.menu_array, new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {

                        switch (which) {
                            case 0:
                            // ...
                        }
                    }
                });

        return builder.create();
    }

What do I need to do, to deactivate (disable) one of the menu item entries? How can I get hold of them? Didn't find the right method in DialogFragment

Disable it where ever you require it in your code, if you want it to be disabled when you show the `AlertDialog` you can put it before you show the `AlertDialog` — Sagar Pilkhwal, Sep 17 '14 at 08:47
@SagarPilkhwal no, I mean in which method would I get hold of the `Menu` reference, I don't have in present. — Mahoni, Sep 17 '14 at 08:49
i have posted the code in the answer with `menu.getItem(1).setEnabled(false);` — Sagar Pilkhwal, Sep 17 '14 at 08:52

public class YourActivity extends Activity {
    private Menu menu;

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        super.onCreateOptionsMenu(menu);
        // Create your menu...
        this.menu = menu;
        return true;
    }
    ....
}

Then use the following code whenever you want to disable the menu item:

menu.getItem(1).setEnabled(false);

Yeah, but when is menu not null? ;-) when I am using the builder it's still null. – Mahoni Sep 17 '14 at 08:57
can you post the code of when you are building your menu ? – Sagar Pilkhwal Sep 17 '14 at 08:59
I've added more code to give you a better idea about the whole DialogFragment, create dialog, set items, show problem. I know how to deactivate menu items in general. – Mahoni Sep 17 '14 at 09:26
try using `alertDialog.getListView();` like in this [SO post](http://stackoverflow.com/q/12946119/3326331) – Sagar Pilkhwal Sep 17 '14 at 09:32
This looks promising, but again it's available in onClick, that's too late. – Mahoni Sep 17 '14 at 10:11
yes you can move the `onClick()` code out of the block, move some edits to the code and then put the code just before you call `show()` on the dialog – Sagar Pilkhwal Sep 17 '14 at 10:12
Still null after a call to `show()`. I tried several method overloadings,.. no luck. The `listView` is there, but does not have any children before onClick happens. – Mahoni Sep 17 '14 at 10:35
