{"delivery_id":"4","client_firstname":"Marie",delivery_status":"On the Road"}

AndroidActivity.java(代码片段)

public static final String DELIVERY_ID = "delivery_id";
public static final String CLIENT_FIRSTNAME = "client_firstname";
public static final String DELIVERY_STATUS = "delivery_status";

JSONArray ja = response.getJSONArray("delivery");

                            for (int i = 0; i < ja.length(); i++) {
                                JSONObject jobj = ja.getJSONObject(i);
                                HashMap<String, String> item = new HashMap<String, String>();
                                String status = "Delivered";

                                if(status == jobj.getString(DELIVERY_STATUS)) {
                                    item.put(DELIVERY_ID, jobj.getString(DELIVERY_ID));
                                    item.put(CLIENT_FIRSTNAME, jobj.getString(CLIENT_FIRSTNAME));
                                    item.put(DELIVERY_STATUS, jobj.getString(DELIVERY_STATUS));
                                }

                                Item_List.add(item);

For this you have to do like this,

为此,你必须这样做,

     if(jobj.getString("delivery_status").equals("Delivered")){

      //your code
     }
