Retrieving Object Name and Position

Hello.

I'll post the code first, then I'll explain-

// Prompts the user for deleting the assignment
    @Override
    public void onItemClicked(View v, int position) {
        mPosition = position;
        mPromptDeleteFragment = new PromptDeleteDialogFragment();
        mPromptDeleteFragment.setListener(mListener2);
        mPromptDeleteFragment.show(getSupportFragmentManager(), PROMPT_FRAGMENT);
    }

    // Prompts the user for creating the assignment
    @Override
    public void createItemClickListener(View v, String string) {
        mListItem = new ListItem();
        mListItem.setAssignment(string);
        mItems.add(mListItem);
        mRecyclerView.scrollToPosition(mItems.size() - 1);
        mListAdapter.notifyDataSetChanged();
        Toast.makeText(MainActivity.this, "\"" + mListItem.getAssignment() + "\"" + " has been created.", Toast.LENGTH_LONG).show();
    }

    // If the user deletes the item
    @Override
    public void confirmDeleteListener(View v) {
        mItems.remove(mPosition);
        mListAdapter.notifyDataSetChanged();
        mPromptDeleteFragment.dismiss();
// I want to create the toast here.
    }

So the scenario here is that I have a RecyclerView that displays a list of ListItem objects, and these objects have a getter that retrieves the name of the object. When the user removes the item from the list (confirmDeleteListener) I want to create a Toast that displays the name of the object, however, I also need to get the position too (the position is an interger). How would I get the ListItem from the position if they're two different object types?

Hi Diego - Wouldn't mItems.get(mPosition) give you the object?

It would get me the position, but I also need to get the object.

But doesn't mItem contain objects of type ListItem?

I just found a fix:

mListItem = mItems.get(mPosition);

Toast.makeText(MainActivity.this, "\"" + mListItem.getAssignment() + "\"" + " has been removed.", Toast.LENGTH_LONG).show();

Thanks anyway!
