Question

我在下面有一个json回复。

{
   "Table":[
      {
         "status":"failed",
         "message":"Questions exausted for the Course"
      }
   ]
}

我必须从回复中读取状态。我试过如下。但我无法阅读。请帮帮我们。

if (result != null
                && !result.toLowerCase()
                        .startsWith("{\"status\":\"invalid") ) {
            mysql.setLastRowCount(lastrowcount);
             System.out.println("PE result in : " + result);
            try {
                JSONObject resultJson = new JSONObject(result);
                JSONArray resultArray = resultJson.getJSONArray("Table");
                String status=resultJson.getString("status");



                System.out.println("Ravi Today "+status);

                for (int i = 0; i < resultArray.length(); i++) {
                    try {
                        JSONObject tempJSONOBJECT = resultArray
                                .getJSONObject(i);
                        bean.setQuestion(tempJSONOBJECT

                    }
                }

Answer 1

尝试如下：

JSONObject resultJson = new JSONObject(result);
JSONArray resultArray = resultJson.getJSONArray("Table");

for (int i = 0; i < resultArray.length(); i++) {

   JSONObject b = venues.getJSONObject(i);
   String status = b.getString("status");

}

Answer 2

试试这个,,,

if(result!=null){
        try {
                JSONObject jsonObj =new JSONObject(result);
                tablejsonarray=jsonObj.getJSONArray("Table");
                for(int i=0;i<tablejsonarray.length();i++){
                    JSONObject l=tablejsonarray.getJSONObject(i);
                    status=l.getInt("status");
                }
            } catch (JSONException e) {
                e.printStackTrace();
            }
    }
