Ok, as android guidelines says, you must create an interface in your fragment. For example:

public class armarFragment extends Fragment implements View.OnClickListener{
    ...
    private armarFragmentListener mListener;

    public interface armarFragmentListener {
        void onEnviar ();
    }

@Override
public void onAttach(Activity activity) {
    super.onAttach(activity);
    try {
        mListener = (armarFragmentListener) activity;
    } catch (ClassCastException e) {
        throw new ClassCastException(activity.toString()
                + " must implement armarFragmentListener ");
    }
}

@Override
public void onClick(View v) {
    switch (v.getId()) {
        case R.id.btnEnviarALaCocina:
            //Do what you want.
            mListener.onEnviar(/*Change interface to pass arguments if you want*/);
        break;
    }
}

Your activity must implements that interface and do what corresponds, for example call the methods of the fragment to get the data. When you have the data you can pass it to the new fragment as arguments or otherwise.

When you create a blank fragment in android studio it put that structure on the class by default. Create a new blank fragment and take a look at it.
