When Threshold is reached, do .......

First of all, thanks for creating a great library!

I am making a little application where the user has a question and 4 possible answers. Next to a possible answer, there is a little scratchcard type section, where they can scratch away to either reveal a star or nothing at all. I am trying to figure out the logic in adding a points system, based on the users actions. In the application, there is a Viewpager, so if they haven't found the star, no points should register, even if they choose to move on after scratching 1 possible answer and not finding the star.

The point is, that they have to find the star for each question. Finding the star straight away will equal 4 points, if they don't find the star on the first go, the points go down to 2 points, if they don't get it again, it goes down to 1 point and the final scratch will reveal the star but they get 0 points if its the last scratch to be revealed.

I am therefore trying to detect when a user has scratched an deal accordingly but I am having trouble with this.

I have the following:

ScratchoffController controller1 = new ScratchoffController(getActivity())
                        .setThresholdPercent(0.40d)
                        .setTouchRadiusDip(getActivity(), 30)
                        .setFadeOnClear(true)
                        .setClearOnThresholdReached(true)
                        .setCompletionCallback(() -> {
                        })
                        .attach(current_layout.findViewById(R.id.scratch_view1), current_layout.findViewById(R.id.scratch_view_behind1));

Then I try to use the following logic

if (array3[answerCount].contains("Correct") && controller1.isThresholdReached()) {
                    current_layout.findViewById(R.id.star1).setVisibility(View.VISIBLE);
                    Score.increaseScoreByFour();
                    ((TextView) current_layout.findViewById(R.id.tv_current_score)).setText(""+Score.getScore());

                }

However controller.isThresholdReached isn't working to detect when the user has scratched, is there another method in the library that will achieve this?

Just realised I can solve with

ScratchoffController controller1 = new ScratchoffController(getActivity())
                .setThresholdPercent(0.40d)
                .setTouchRadiusDip(getActivity(), 30)
                .setFadeOnClear(true)
                .setClearOnThresholdReached(true)
                .setCompletionCallback(() -> {
                    if (array3[answerCount].contains("Correct")) {
                        current_layout.findViewById(R.id.star1).setVisibility(View.VISIBLE);

                        Score.increaseScoreByFour();
                        ((TextView) current_layout.findViewById(R.id.tv_current_score)).setText("" + Score.getScore());
                    }
                })
                .attach(current_layout.findViewById(R.id.scratch_view1), current_layout.findViewById(R.id.scratch_view_behind1));
