AsyncTask和doInBackground错误

更改

 protected Void doInBackground(String airfield)

至

 protected Void doInBackground(String... airfield)

要么

 protected Void doInBackground(String[] airfield)

因为doInBackground（）方法需要将字符串数组作为参数

并更改为

   try {        doc = Jsoup     .connect(  "https://pilotweb.nas.faa.gov/PilotWeb/notamRetrievalByICAOAction.do?method=displayByICAOs")     .data("retrieveLocId", airfield[0])     .data("formatType", "ICAO")     .data("reportType", "REPORT")     .data("actionType", "notamRetrievalByICAOs")     // .userAgent("Mozilla")     // .cookie("auth", "token")     .timeout(3000).post();    } catch (IOException e) {        // TODO Auto-generated catch block        e.printStackTrace();    }
