私のアプリケーションの logcat は、いくつかの IndexOutOfBound 例外を示しています。 Webサービスを利用するためのSOAPメソッドに従ってください。プロジェクトで犯している間違いを誰か教えてもらえますか?

提案してください!..

貴重な時間をありがとう！.

サーバー側から何かを取得してもよろしいですか？要素を取得する前に、結果リストのサイズをチェックしません。この文字列の私の問題については、 in.putExtra("gotonextpageX", result.get(0)); in.putExtra("gotonextpageY", result.get(1));

範囲外の配列インデックスをメイン アクティビティ コードに追加します。

try

    androidHttpTransport.call(NAMESPACE + METHOD, envelope);
    SoapObject result = (SoapObject) envelope.bodyIn;
    SoapObject root = (SoapObject) ((SoapObject) (result).getProperty(0)).getProperty("NewDataSet");
    int tablesCount = root.getPropertyCount();

    for (int i = 0; i < tablesCount; i++) 
    {
        SoapObject table = (SoapObject) root.getProperty(i);
        int propertyCount = table.getPropertyCount();

        for (int j = 0; j < propertyCount; j++) 
        {

            stringResult.add(table.getPropertyAsString("Order_No").toString());
            stringResult.add(table.getPropertyAsString("Freight_Rate").toString());

        //  stringResult.add(table.getPropertyAsString("Margin_Percent").toString());
