Reset results and TextUtil

So, I got a feedback from reviewer and fixed most of my problems but there are two problems that I can’t find solution (I will use bold font to highlight them) the first problem comes after I click result button more than one time because the previous result is added. I know that I should add all the methods checkQuestionOne to checkQuestion6 in the button method but this is not possible so far because the method needs (View or view value) which is not working and I don’t know why so I decided not to include the four Radio buttons methods in it. Second when the checkQuestionFive is blank or there is no value the app crashes I was told to use if (!TextUtils.isEmpty(gettingQuestionFive.getText())), then I add Toast message into the if statement but it still crashes. Any help will be appreciated!!

Thank you!

Java code:

    int health = 0;

        Toast displayToast = Toast.makeText(this, health + " is your score. If is 4 or above, you have a healthy life", Toast.LENGTH_LONG);
        displayToast.show();
        health = 0;
