Button in Fragment class (mDeleteButton)

Hi everyone,

In this code challenge, I am not sure where I should write the code for mDeleteButton.

I wrote it in the onCreateView method, see below:

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

        View rootView = inflater.inflate(R.layout.fragment_photo, container, false);
        mDeleteButton = (Button)findViewById(R.id.deleteButton);
        return rootView;
    }

However, the error is: For fragments, we must call the 'findViewById()' method from the 'rootView' that is created.

Any ideas? Thanks in advance!

David

When referencing a view from an XML file from a fragment (like in this case mDeleteButton) you must tell in which view is contained (rootView), so the whole thing should look like this:

mDeleteButton = (Button) rootView.findViewById(R.id.deleteButton);

That should make it.
