Android の kSoap に関するチュートリアルを行いました。

My Code は Android 2.2 では動作しますが、Android 4.0.3 では動作しません! コードを ... に切り替える必要があると聞きましたが、そのAsyncTask方法がわかりません。誰でも私を助けることができますか？

これが私のコードです！

今、私は AsyncTask でそれを試しましたが、まだ動作しません! ヘルプはありますか？

async クラスの doInBackground メソッドにコードを記述します

  private class async extends AsyncTask<String, Void, String> {

      @Override
      protected String doInBackground(String... params) {

            }

            return "Executed";
      }      

      @Override
      protected void onPostExecute(String result) {

      }

      @Override
      protected void onPreExecute() {
      }

      @Override
      protected void onProgressUpdate(Void... values) {
      }
}

そしてボタン呼び出しのクリックで

 new async().execute();

あなたがしなければならないのは、クラスを作成することだけです

private class TaskAsync extends AsyncTask<String, Void, String> {

      @Override
      protected String doInBackground(String... params) {

            // Do all your connection stuff here

            return "Executed";
      }      

      @Override
      protected void onPostExecute(String result) {
           // here you fetch the data into the UI widgets
      }

      @Override
      protected void onPreExecute() {
      }

      @Override
      protected void onProgressUpdate(Void... values) {
      }
}

そしてただ電話する

new TaskAsynk().execute;

それが役立つことを願っています
