如何使用上述代碼在java中創建Json對象請給我代碼。我在堆棧溢出搜索，但我沒有得到相同的JSON格式的JSON對象代碼如何在bellow中創建jsonObject在java中的結構

請張貼相關的代碼 – Pehlaj

使用這個工具：http://www.jsonschema2pojo.org/ –

可能[使用Volley發送帶有JSON數據的POST請求]的副本（http://stackoverflow.com/questions/23220695/send-post-request-with-json-data-using-volley） –

這是示例代碼片段。

class DATATABLE{ 
    String ENTITYID; 
    .... define all fileds here. 
} 

class Data{ 
    List <'DATATABLE> list; 
    String Mode; 
}

歡迎來到Stack Overflow！雖然此代碼可能會回答這個問題，但提供關於_how_和/或_why_的附加[上下文]（https://meta.stackexchange.com/q/114762）可以解決問題，從而提高答案的長期價值。請記住，你正在爲將來的讀者回答這個問題，而不僅僅是現在問的人！請[編輯]（http://stackoverflow.com/posts/43272560/edit）您的答案添加一個解釋，並指出適用的限制和假設。它也不會提到爲什麼這個答案比其他答案更合適。 –

創建JSON PARAM喜歡它，並將其發送PARAM與凌空要求

JSONObject paramObj = new JSONObject(); 
JSONArray dataArray = new JSONArray(); 
JSONObject Obj = new JSONObject(); 
Obj.put("ENTITYID", "2"); 
Obj.put("USERID", "2"); 

// and so on.... 

// Now put obj into array 
dataArray.put(0, Obj); 

// put array and last value into paramObj 
paramObj.put("DATATABLE", dataArray); 
paramObj.put("Mode", "I");

發送「paramObj」的JSONObject與凌空要求PARAM。

和更多關於如何使用JSON參數排氣可以休耕this教程這將是對你有所幫助。

我已經用volley來解析上面的json格式。爲下面的代碼解析您的網址。

清單文件：

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
    package="com.theme.androidvolley"> 
    <uses-permission android:name="android.permission.INTERNET"/>

     android:supportsRtl="true" 
     android:theme="@style/AppTheme"> 
     <activity android:name=".MainActivity"> 
      <intent-filter> 
       <action android:name="android.intent.action.MAIN" /> 
       <category android:name="android.intent.category.LAUNCHER" /> 
      </intent-filter> 
     </activity> 
    </application> 
</manifest>

AppController.Java

public class AppController extends Application { 
    public static final String TAG = AppController.class.getSimpleName(); 
    private RequestQueue mRequestQueue;

     super.onCreate(); 
     mInstance = this; 
    } 
    public static synchronized AppController getInstance() { 
     return mInstance; 
    } 
    public RequestQueue getRequestQueue() { 
     if (mRequestQueue == null) { 
      mRequestQueue = Volley.newRequestQueue(getApplicationContext()); 
     } 
     return mRequestQueue; 
    } 
    public <T> void addToRequestQueue(Request<T> req, String tag) { 
     req.setTag(TextUtils.isEmpty(tag) ? TAG : tag); 
     getRequestQueue().add(req);
