令牌上的语法错误,而不是AnnotationName - 查询时出错

标签: java android android-layout android-fragments parse-platform

我收到了令牌上的语法错误,预期AnnotationName会出现在以下行:

query.findInBackground(new FindCallback<ParseUser>() {

我一直试图排除故障,但仍然遇到困难。

以下是我的完整代码

public class Fragment1 extends Fragment {

<强>问题:

query实际上超出范围,您将query.findInBackground(new FindCallback<ParseUser>() {放在public void done(java.util.List<ParseObject> objects, ParseException e)之外,从而为您提供该错误,因为查询变量位于done方法内。

<强>溶液

将它放在匿名类的完成方法

query.findInBackground(new FindCallback() {

        @Override
        public void done(java.util.List<ParseObject> objects,ParseException e) {
                ParseQuery<ParseObject> query = ParseQuery.getQuery("User");

                ParseImageView imageView = (ParseImageView) getView().findViewById(R.id.profilePictureResult);

                // The placeholder will be used before and during the fetch, to be replaced by the fetched image
                // data.
                imageView.setPlaceholder(getResources().getDrawable(R.drawable.profile_pict));
                imageView.setParseFile(image);
                imageView.loadInBackground(new GetDataCallback() {
