Need Help with Task 1 of CodeChallenge

Can anyone help me with task 1 of this Code Challenge it's on Android- Build a Self-Destructing Message Android App- Understanding the Rest of the Pieces.

The Question is "We have a Button (mDeleteButton) in our Fragment class below. Set it to the button in the layout with the ID of 'deleteButton'."

The Code so far is

import android.app.Fragment; import android.os.Bundle; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; import android.widget.Button;

public class PhotoFragment extends Fragment {

public Button mDeleteButton;

>@Override
>public void onCreate(Bundle savedInstanceState) {
>>super.onCreate(savedInstanceState);
>}
>
>@Override
>public View onCreateView(LayoutInflater inflater, ViewGroup >container, Bundle savedInstanceState) {
>      View rootView = inflater.inflate(R.layout.fragment_photo, >container, false);
>      return rootView;
>}
>}

Now the Question seems pretty Straight Forward and I assume I have to use findViewById but where ever I put it comes up as wrong answer!

since you are in a fragment, the findViewById method needs to be called on the rootView object that is created in the onCreateView method:

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_photo, container, false);
        //find the button with the id of deleteButton using the rootView object
        mDeleteButton = (Button) rootView.findViewById(R.id.deleteButton);
        return rootView;
    }
