Question

我正在做一个用户可以输入比赛卡丁车号码的项目，它会显示相应的卡丁车比赛详情。但我不确定如何将编辑文本值添加到AsyncTask中的URL。

代码

int kartNumber = Integer.parseInt(etGokart.getText().toString());
.......
 .......
 protected JSONObject doInBackground(String... urls) {
        try {
            URL url = new URL("http://race.speedtiming.com/api/index.php/races/scoreboard.json?track_id=3");//**-->how to include kart number there in url**
            HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
            urlConnection.setRequestMethod("GET");
..........
..........
}

Answer 1

希望这有帮助

int kartNumber = Integer.parseInt(etGokart.getText().toString());
String urlWithoutKartNum = "http://race.speedtiming.com/api/index.php/races/scoreboard.json?track_id=#kart_num#";
.......
.......
 protected JSONObject doInBackground(String... urls) {
        try {

            URL url = new URL(urlWithoutKartNum.replace("#kart_num#", kartNumber););//**-->how to include kart number there in url**
            HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
            urlConnection.setRequestMethod("GET");
..........
..........
}

或者您可以直接将其添加为：

"http://race.speedtiming.com/api/index.php/races/scoreboard.json?track_id="+ kartNmber;

Answer 2

只需将editText值添加到网址，如下所示：

      int kartNumber = Integer.parseInt(etGokart.getText().toString());
        .......
        .......
         protected JSONObject doInBackground(String... urls) {
         try {
               URL url = new URL("http://race.speedtiming.com/api/index.php/races/scoreboard.json?track_id="+kartNumber);//**-->how to include kart number there in url**
               HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
               urlConnection.setRequestMethod("GET");
        ..........
        ..........


   }
