JSON在Android的

Question

解析我得到從PHP主機JSON響應

{ 「UID」： 「0」}

我想從它

檢索0（即UID數值）我試圖取回..但有例外

這是我的代碼..

HttpEntity entity = response.getEntity(); 

} catch(Exception e) { 
    System.out.println("Exception : " + e.getMessage()); 
} 
finally { 
    if (conn != null) { 
     try { 
      conn.close(); 
     } 
     catch (Exception e) { e.printStackTrace(); } 
    } 
} 

//convert response to string 
/* 
try { 
    BufferedReader reader = new BufferedReader(new InputStreamReader(is, "iso-8859-1"),8); 
    StringBuilder sb = new StringBuilder(); 
    String line = null; 
    while ((line = reader.readLine()) != null) { 
     sb.append(line+"\n"); 
    } 
    is.close(); 
    result = sb.toString(); 
} catch(Exception e) { 
    System.out.println("Exception : " + e.getMessage()); 
} 
try 
{ 
    ?????????????????????????? 
} catch(Exception e) { e.printStackTrace(); } 

Answer 1

只需使用JSONOBJECT。

JSONObject obj = new JSONObject(src); 
if (obj.has("uid")){ 
    String uid = obj.getString("uid"); 
} 

Answer 2

使用GSON使得這很容易
