URLに編集テキストの値を追加

Question

私はユーザーがレースカート番号を入力できるプロジェクトを行っており、対応するカートのレースの詳細が表示されます。しかし、私はどのようにAsyncTaskのURLに編集テキストの値を追加するか分からない。

ここにコード

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

同じように、以下のURLへeditText値を追加します。

を

 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"); 
     .......... 
     .......... 


    } 

Answer 2

希望これは

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"); 
.......... 
.......... 
} 

それとも、直接それが好きで追加することができます役立ちます。

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

    protected JSONObject doInBackground(String... urls) { 
    try { 
      String urlText = MessageFormat.format("http://race.speedtiming.com/api/index.php/races/scoreboard.json?track_id={0}", kartNumber); 
      URL url = new URL(urlText); 
      HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection(); 
      urlConnection.setRequestMethod("GET"); 
    ..........
