從改造響應中獲取數據json array

Question

我正在開發Android版Retrofit，我對此很陌生。我正確實現了api並獲得了json響應。 在我的回覆中，我有狀態，數據，信息。這裏的數據類是一個數組，我發現訪問數組內的項目（id，title，url，image）時遇到困難。我如何工作這些項目。

我需要將圖像url設置爲imageview。

這是我的java類在那裏我打電話改造

ApiInterface apiInterface = AppController.GetRetrofitObject().create(ApiInterface.class); 
      Call<SocialData> call = apiInterface.socialContent(accessToken,tokenType,client,expiry,uid); 
      call.enqueue(new Callback<SocialData>() { 
       @Override 
       public void onResponse(Call<SocialData> call, Response<SocialData> response) { 

        Data[] data=response.body().getData(); 
        i=data.length; 
        String count= String.valueOf(i); 
        Toast.makeText(context,count,Toast.LENGTH_LONG).show(); 

       } 

       @Override 
       public void onFailure(Call<SocialData> call, Throwable t) { 

       } 
      }); 

所以在這裏我能看到陣列計數。

這是我的json response.I需要設置圖像url到imageview。

{ 
    "status": 200, 
    "data": [ 
    { 
    "id": 1, 
    "title": "Six WhatsApp Features You May Not Know About ", 
    "url": "http://gadgets.ndtv.com/apps/features/six-whatsapp-features-you-may-not-know-about-1658812?pfrom=home-indepth", 
    "image": { 
    "url": "/uploads/social_medium/image/1/Whatsapp-for-PC.jpg" 
    }, 
    "bypass": false 
}, 
{ 
    "id": 2, 
    "title": "How to Delete Your Snapchat Account ", 
    "url": "http://gadgets.ndtv.com/apps/features/how-to-delete-your-snapchat-account-1658799?pfrom=home-indepth", 
    "image": { 
    "url": "/uploads/social_medium/image/2/snapchat_code_picjumbo_1486964243543.jpg" 
    }, 
    "bypass": false 
}, 
{ 
    "id": 3, 
    "title": "Jadeja, Ishant wrap up India's 208-run win", 
    "url": "http://www.espncricinfo.com/india-v-bangladesh-2016-17/content/story/1082146.html", 
    "image": { 
    "url": "/uploads/social_medium/image/3/259024.jpg" 
    }, 
    "bypass": false 
}, 
{ 
    "id": 4, 
    "title": "10 Facts On the Disproportionate Case Against VK Sasikala", 
    "url": "http://www.ndtv.com/india-news/10-facts-on-the-disproportionate-case-against-vk-sasikala-1659078", 
    "image": { 
    "url": null 
    }, 
    "bypass": false 
} 

], 
    "message": { 
"success": "Success" 
    } 
    } 

我得到pojo類，如下所示。

SocialData.java

public class SocialData { 

private Message message; 

private String status; 

private Data[] data; 

public Message getMessage() 
{ 
    return message; 
} 

public void setMessage (Message message) 
{ 
    this.message = message; 
} 

public String getStatus() 
{ 
    return status; 
} 

public void setStatus (String status) 
{ 
    this.status = status; 
} 

public Data[] getData() 
{ 
    return data; 
} 

public void setData (Data[] data) 
{ 
    this.data = data; 
} 

@Override 
public String toString() 
{ 
    return "ClassPojo [message = "+message+", status = "+status+", data = "+data+"]"; 
} 

}

Message.java

public class Message { 

private String success; 

public String getSuccess() 
{ 
    return success; 
} 

public void setSuccess (String success) 
{ 
    this.success = success; 
} 

@Override 
public String toString() 
{ 
    return "ClassPojo [success = "+success+"]"; 
} 

} 

Data.java

public class Data { 

private String id; 
private String title; 
private String bypass; 
private Image image; 

private String url; 

public String getId() 
{ 
    return id; 
} 

public void setId (String id) 
{ 
    this.id = id; 
} 

public String getTitle() 
{ 
    return title; 
} 

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

public String getBypass() 
{ 
    return bypass; 
} 

public void setBypass (String bypass) 
{ 
    this.bypass = bypass; 
} 

public Image getImage() 
{ 
    return image; 
} 

public void setImage (Image image) 
{ 
    this.image = image; 
} 

public String getUrl() 
{ 
    return url; 
} 

public void setUrl (String url) 
{ 
    this.url = url; 
} 

@Override 
public String toString() 
{ 
    return "ClassPojo [id = "+id+", title = "+title+", bypass = "+bypass+", image = "+image+", url = "+url+"]"; 
} 

} 

Image.java

public class Image { 

private String url; 

public String getUrl() 
{ 
    return url; 
} 

public void setUrl (String url) 
{ 
    this.url = url; 
} 

@Override 
public String toString() 
{ 
    return "ClassPojo [url = "+url+"]"; 
} 

} 

我得到的回覆很好。

Answer 1

要建立正確的POJO類改造使用這個網站：http://www.jsonschema2pojo.org

和複製oyur JSON

組源類型：JSON 組註釋風格:: GSON

你會得到正確的類。 。

獲取數據

創建SocialData的目的等

SocialData data = response.body(); 

，並使用該數據對象 。 像

List<Datum> datalist = new ArrayList<>(); 
datalist = data.getData(); 

Toast.makeText（上下文 「」 + datalist.size（），Toast.LENGTH_LONG）。顯示（）;
