GSON預計BEGIN_ARRAY但路線是BEGIN_OBJECT 1列2路$

Question

這是我的ArrayList

ArrayList<Eat> eatList = gson.fromJson(jsonString, new 
TypeToken<ArrayList<Eat>>() { 
      }.getType()); 

這是我的JSON：http://www.mocky.io/v2/592fdc32110000ef12b392cc

，這是我的模型

public class Eat{ 

private String title,firstItemTitle,firstItemSutitle, 
secondItemTitle,secondItemSutitle, 
firstItemPrice,secondItemPrice, 
firstItemImage,secondItemImage; 


public String getTitle() { 
    return title; 
} 

public void setTitle(String title) { 
    this.title = title; 
} 

public String getFirstItemTitle() { 
    return firstItemTitle; 
} 

public void setFirstItemTitle(String firstItemTitle) { 
    this.firstItemTitle = firstItemTitle; 
} 

public String getFirstItemSutitle() { 
    return firstItemSutitle; 
} 

public void setFirstItemSutitle(String firstItemSutitle) { 
    this.firstItemSutitle = firstItemSutitle; 
} 

} 

Answer 1

由於您的JSON不是JSON數組，而是包含數組的JSON 對象，您需要編寫一個包含的類：

public class EatResponse { 
    @SerializedName("eat") 
    private ArrayList<Eat> eatList; 

    public ArrayList<Eat> getEatList() { 
     return eatList; 
    } 
} 

然後，你只需要解析您的JSON與呼叫會是這個樣子：

EatResponse response = gson.fromJson(json, EatResponse.class); 
ArrayList<Eat> eatList = response.getEatList();
