創建2類(Meal
,Restaurant
)延伸ParseObject
,以及創建自定義2個適配器(BottomFragmentMealAdapter
,RestaurantAdapter
)。我試圖做我在BottomFragmentMealAdapter
(它工作)爲RestaurantAdapter
做的任何事情。但它不起作用。
這是我的日誌:java.lang.ClassCastException:com.parse.ParseObject不能轉換到

這是我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:
query.orderByDescending("averagePrice");
break;
case 2:
query.orderByAscending("restaurant");
break;
case 3:
query.orderByDescending("averagePoint");
break;
default:
query.orderByAscending("restaurant");
break;
}
return query;
}
});
}
@Override
public View getItemView(Restaurant restaurant, View v, ViewGroup parent) {
//buttonClick = new AlphaAnimation(1F, 0.8F);
if (v == null) {
v = View.inflate(getContext(), R.layout.restaurant_list_item, null);
}
super.getItemView(restaurant, v, parent);
final String str_call = restaurant.getPhone();
TextView locationTextView = (TextView) v.findViewById(R.id.restaurant_location);
