我创建了两个扩展了Meal的类(Restaurant，ParseObject)，并创建了两个自定义适配器(BottomFragmentMealAdapter，RestaurantAdapter)。我尝试为BottomFragmentMealAdapter做我在RestaurantAdapter中所做的任何事情(它可以工作)。但这是行不通的。
这是我的日志:
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:
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);
String str_location= restaurant.getRegion()+", "+restaurant.getCity();
locationTextView.setText(str_location);
TextView nameTextView = (TextView) v.findViewById(R.id.restaurant_name);
nameTextView.setText(restaurant.getName());
TextView pointTextView = (TextView) v.findViewById(R.id.restaurant_point);
String str_point = String.valueOf(restaurant.getAveragePoint());
pointTextView.setText(str_point);
TextView priceTextView = (TextView) v.findViewById(R.id.restaurant_averageprice);
String str_price = String.valueOf(restaurant.getAveragePrice())+" TL";
priceTextView.setText(str_price);
ImageView callImage = (ImageView) v.findViewById(R.id.restaurant_call);
callImage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View w) {
// w.startAnimation(buttonClick);
Intent intent = new Intent(Intent.ACTION_DIAL);
intent.setData(Uri.parse("tel:"+str_call));
w.getContext().startActivity(intent);
}
});
TextView mapText = (TextView) v.findViewById(R.id.restaurant_map);
mapText.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View w) {
//w.startAnimation(buttonClick);
}
});
return v;
}
}
最佳答案
你必须检查两件事
public default(即零参数)构造函数。您不得在此构造函数中修改任何ParseObject字段。和
ParseObject.registerSubclass(YourClass.class)之前，在您的Application构造函数中调用Parse.initialize()。
