我正在尝试在我的一个片段中实现搜索功能，因为用户类型列表将变得更加定义并匹配用户输入。
我让代码在一个活动中工作但是在尝试在片段中实现它时我遇到了错误。我在下面的代码段中收到错误消息，指出.setFilterQueryProvider无法解析。
有谁可以指出我可能出错的地方？
代码段
adapter.setFilterQueryProvider(new FilterQueryProvider() {
public Cursor runQuery(CharSequence constraint) {
return db.fetchRecipes(constraint.toString());
}
});
