Android 获取多个评级条的值，并设置可以使用的星数限制

我正在做一个有片段的项目，我有4个评级条（每个都有四颗星），用户只能使用所有评级条中的10个“星”

我现在正在尝试将这些值相加，但即使这样也不起作用。我希望能够将所有值相加，然后限制在所有评级中可以设置多少值

FragmentRatings.java：

public class FramentRatings extends Fragment{
    RatingBar rbStrength, rbIntellect, rbWisdom, rbDexterity;
    TextView tvPointSpent;
    float pointsS, pointsI, pointsW, pointsD, total;

    private SharedPreferences prefs;

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_ratings, container, false);

        rbStrength = (RatingBar)view.findViewById(R.id.strengthRating);
        rbIntellect = (RatingBar)view.findViewById(R.id.intellectRating);
        rbWisdom = (RatingBar)view.findViewById(R.id.wisdomRating);
        rbDexterity = (RatingBar)view.findViewById(R.id.dexterityRating);


        tvPointSpent = (TextView)view.findViewById(R.id.tvPointsSpend);

        rbStrength.setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener() {
            @Override
            public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromUser) {
                tvPointSpent.setText(""+rbStrength.getRating());
                pointsS = rbStrength.getRating();
            }
        });

        rbIntellect.setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener() {
            @Override
            public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromUser) {
                //tvPointSpent.setText(""+rbIntellect.getRating());
                pointsI = rbIntellect.getRating();
            }
        });

        rbWisdom.setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener() {
            @Override
            public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromUser) {
                //tvPointSpent.setText(""+rbStrength.getRating());
                pointsW = rbWisdom.getRating();
            }
        });

                pointsD = rbDexterity.getRating();
            }
        });

        total = pointsD + pointsI + pointsS + pointsW;

        tvPointSpent.setText(""+pointsS);

        return view;

可能逻辑有误，但行不应该：

tvpointwasted.setText（“+pointsS”）

是：

---

tvpointwasted.setText（String.valueOf（total））

我可能很晚了，但是

我建议的一个快速修复方法是

pointsS=ratingBar.getRating（）
或
pointsS=额定值和rest类似，因为函数
onRatingChanged（…）
中的这些参数用于获取更改后的值和最终值。
不是Android开发人员，但似乎没有在之前/之后捕获一次更改事件。所以我可能要做的是为你的每个统计数据创建“当前”值。例如，使用正在更改的强度，我将使用currentwistence+currentIntelligent+currentDextrity+rbStrength.getRating（），如果它大于10，我可以：a）rbStrength.setRating（currentStrength）//重置或b）rbStrength.setRating（10-currentwistence-currentIntelligent-currentDextrity）//我可以设置它的最大剩余值。如果是
