Referencing a menu itemId in android studio

Question

I was wondering how i reference the menu Item i have created, in my switch? Thank you in advance.

MY menu Item:

@Override
public void onCreateContextMenu(ContextMenu menu, View v, 
ContextMenu.ContextMenuInfo menuInfo) {

        menu.setHeaderTitle("Vælg en handling");

        //I just want one of the menu items under referenced.
        menu.add(0,0,0, "Slet denne regning");
        menu.add(0,1,0, "Omdøb denne regning");

    }

And my Switch Case:

@Override
public boolean onContextItemSelected(MenuItem item) {
    adapter.getSelectedItem(item);

    switch (item.getItemId()){
        case //This is where i want one of my menu items referenced :
            finish();
    }

    return super.onContextItemSelected(item);
}

It should also be noted that my switch is in my mainActivity, and my Menu item is in another class(A Recycler adapter).

In your menu.xml file you define an id for the item e.g. @+id/menu_item

<item
        android:id="@+id/menu_item"
        android:icon="@drawable/item"
        android:title="Item"
        android:visible="true"
        app:showAsAction="ifRoom" />

Then in your switch, you add R.id.menu_item:

//...
switch(item.getItemId()) {
            case R.id.menu_item:
                doAction();
                break;
//...

I haven't got a xml file but i made the item directly with the id of "0" istead. – Otto Aug 02 '18 at 20:39
Like so " menu.add(0,0,0, "Slet denne regning");" this is the item i want refferenced :) – Otto Aug 02 '18 at 20:41
@Otto the second argument in your method is the Id, try using it case 0 would be for "Slet denne regning", case 1 for "Omdøb denne regning" – Maciej Beimcik Aug 02 '18 at 20:47
Okay ill try that too Thank you – Otto Aug 02 '18 at 20:52

Declare in your activity:

public class MainActivity extends AppCompatActivity {
    MenuItem mi;

The add method returns the menuitem:

mi = menu.add(0,0,0, "Slet denne regning");

and in onContextItemSelected:

if (item == mi) {
  //your code here
}

It seems too be right exept that i cannot resolve the symbol mi in my mainactivity – Otto Aug 02 '18 at 20:53
Declare it on top just before onCreate(); – Aug 02 '18 at 20:55
How would you do that? – Otto Aug 02 '18 at 21:11
see my edited answer. The variable mi needs to be global in the activity. – Aug 02 '18 at 21:13
My "mi = menu.add(0,0,0, "Slet denne regning");" is in another class, than MainActivity :P – Otto Aug 02 '18 at 21:19
What is this a popup menu or the activity's main menu? – Aug 02 '18 at 21:23
Well it is a menu that popups from a recyclerView item. so i have created the menu itself in my recyclerView adapter, and then afterwards called the menu in my mainactivity to make it apear, wich also is where i give it actions. – Otto Aug 02 '18 at 21:25
Yeah but that might still be the problem, thank you for the help :) but i'll have to look at it toomorrow :) – Otto Aug 02 '18 at 21:42
