Android- JSON對象

Question

PHP服務器包含此

$test_array = array(
    'array1' => array(
      'field1'=>'1', 
      'field2'=>'2'), 
    'array2'=>array(
      array('field3'=>'3', 'field4'=>'4', 'field4'=>'5') 
    ) 

）;

如何在Android中使用JOSN對象來填充「test_array」？

Answer 1

所有你需要返回此響應的第一：接收響應後

header('Content-Type: application/json'); 
echo json_encode($test_array); 

在Android應用程序：

yourJSONOBject.put("new_key", "new_value); 

Answer 2

打造的Android

JSONObject a = new JSONObject("{hello1: hi, hello2: hey}"); 
params= a.toString() 

一個JSONObject進行獲取請求到php服務器 看這裏：http://veerasundar.com/blog/2011/09/making-get-and-post-requests-in-android-application/

，然後在PHP解析帕拉姆爲JSON

json_decode($_GET['param']) 

Answer 3

這裏是我的代碼片段，解析取決於我們的JSON結構

try { 
URL url = new URL("http://www.domain.com/data.json"); 
InputStream input = url.openStream(); 

BufferedReader r = new BufferedReader(new InputStreamReader(input)); 
StringBuilder total = new StringBuilder(); 
String line; 

while ((line = r.readLine()) != null) { 
    total.append(line); 
} 

JSONArray jsonReply = new JSONArray(total.toString()); 

for (int i = 0; i < jsonReply.length(); i++) { 
     JSONObject jObject = jsonReply.getJSONObject(i); 
} 

} catch (Exception e) { 
}
