获取多个分级条值，并设置可以使用的星数限制
获取多个分级条值，并设置可以使用的星数限制
提问于 2017-07-01 04:12:43
我正在做一个碎片项目，在那里我有4个评级条(每个4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的值的数量。
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();
}
});
rbDexterity.setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener() {
@Override
public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromUser) {
//tvPointSpent.setText(""+rbStrength.getRating());
pointsD = rbDexterity.getRating();
}
});
total = pointsD + pointsI + pointsS + pointsW;
tvPointSpent.setText(""+pointsS);
return view;
}

可能把逻辑搞错了，但这句话不应该：
tvPointSpent.setText(""+pointsS)；
be：
TvPointSpent.setText(String.valueOf(总数))；

我可能来晚了，但是
我建议使用pointsS = ratingBar.getRating();或pointsS = rating;作为rest的快速解决方案，因为函数onRatingChanged(...)中的这些参数将获取更改后的和最终的值。
