java.lang.ClassCastException：不能将Com.Parse.ParseObject强制转换为

Question

这是我的RestaurantAdapter

public class RestaurantAdapter extends ParseQueryAdapter<Restaurant> {
    //top line is 17
    private AlphaAnimation buttonClick;
    public RestaurantAdapter(Context context, final String filter_edit, final String filter_city, final String filter_region,0 final int filter_sort) {
       super(context, new ParseQueryAdapter.QueryFactory<Restaurant>() {
           public ParseQuery<Restaurant> create() {
               // Here we can configure a ParseQuery to display
               // only top-rated meals.
               ParseQuery query = new ParseQuery("Restaurant");
               query.whereContains("city", filter_city);       
    if(!filter_region.equals("*Hepsi*")&&!filter_region.equals("*All*"))
                   query.whereContains("region",filter_region);
               if(filter_edit.equals("nothing")){
               }else{
                   query.whereStartsWith("restaurant", filter_edit);
               }
               switch(filter_sort){
                   case 0:
                       query.orderByAscending("averagePrice");
                       break;
                   case 1:

你得检查两件事

确保您的子类具有public default（即零参数）构造函数。不能修改此构造函数中的任何ParseObject字段。而且

在调用Parse.Initialize()之前，在应用程序构造函数中调用ParseObject.RegisterSubclass(YourClass.Class)。
