AlertDialog not appearing on screen

I'm trying to create a loading dialog using an AlertDialog inside a Retrofit call, however this loading dialog is not showing up at all. I want to show it while the call is downloading and setting up the recyclerView. Right now the dialog is not showing up at all, it sets the recyclerView and everything without showing the dialog. I'm not sure if this matters but this is inside a fragment.

This is the full retrofit call

Call<List<Evaluator>> call = apiInterface.getSurveys();

call.enqueue(new Callback<List<Evaluator>>() {
    @Override
    public void onResponse(Call<List<Evaluator>> call, Response<List<Evaluator>> response) {
        if (!response.isSuccessful()) {
            //show error toast
        }

        AlertDialog.Builder builder = new AlertDialog.Builder(activity);
        builder.setCancelable(true);
        LayoutInflater inflater = getLayoutInflater();
        inflater.inflate(R.layout.dialog_loading, null);

        AlertDialog dialog = builder.create();
        dialog.show();

        List<Evaluator> masterItem = response.body();

        masterItem.forEach(evaluator -> {
            if (!evaluator.getAnswered()) {
                surveys.add(new Evaluator(evaluator));
            }
        });

        mAdapter = new SurveyAdapter(surveys);
        mRecyclerView.setAdapter(mAdapter);

        dialog.dismiss();
    }

    @Override
    public void onFailure(Call<List<Evaluator>> call, Throwable t) {
        //show error toast
    }
});

call dialog.show() before you call retrofit call.enqueue. And inside response or failure dismiss the dialog.

And don't forget to dismiss dialog in both onResponse and onFailure.
