多个接口实现 Android [重复]

问：

我有一个 Activity，它实现了两个接口，用于对某些操作进行回调。我想将我的 Activity 的上下文发送到另一个 Class，该 Class 将访问指定回调的对象。

这是我的代码：-

     public class OpenSchoolFragment extends Fragment implements IOpenSchoolCallBack, INetworkCallback
    {
// 1st case
       expandableListAdapter = new AdapterOpenSchool(getActivity(), this); // IOpenSchoolCallBack should provided

//2nd case
call.enqueue(new Callback<OpenSchool>()
        {
            @Override
            public void onResponse(Call<OpenSchool> call, Response<OpenSchool> response)
            {

                if (response.isSuccessful())
                {
                    OpenSchool userBatch = response.body();
                    if (userBatch != null)
                    {
                        RLProgressRoot.setVisibility(View.GONE);
                    }
                }
                else
                {
                    RLProgressRoot.setVisibility(View.GONE);
                    if (response.code() == getResources().getInteger(R.integer.integer_404))
                    {
                        DialogHelperUtil.showRetrySnackbar(RLContainer, getString(R.string.str_error_unauthorised),this); //INetworkCallBack should be provided

                    }
                    else
                    {
                        DialogHelperUtil.showMessageSnackbar(RLContainer, response.raw().message());
                    }
                }
            }

        }

因此，当我尝试在第二种情况下传递“this”时，我收到一个错误，说：-

Wrong 3rd argument type. Found: 'Callback<OpenSchool>', required: 'INetworkCallback'

对于第二种情况，我如何确保在“this”中传递正确的回调，即。?INetworkCallback
