android - 运行我的 android 应用程序后，Logcat 显示 IndexOutOfBound 异常

Question

我的应用程序的 logcat 显示了一些 IndexOutOfBound 异常。这里我正在尝试使用 achartengine 库在 android 中创建条形图。我通过使用它从 Web 服务获取 x 轴和 y 轴值，我是遵循使用 Web 服务的 SOAP 方法。谁能让我知道我在项目中犯了什么错误？

请给点建议！..

感谢您宝贵的时间！..

你确定你从服务器端得到一些东西吗？在从中获取元素之前，您不会检查结果列表大小。至于我这个字符串中的问题 in.putExtra("gotonextpageX", result.get(0)); in.putExtra("gotonextpageY", result.get(1));

将 Array index out of bound 异常添加到您的主活动代码

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());

        //  freightRate = Integer.parseInt(table.getPropertyAsString("Freight_Rate"));

        }
    }
}
catch (ArrayIndexOutOfBoundException e) 
{}
catch (Exception e) 
{}

尝试更换

            android:label="@string/title_activity_chart__main" >
<intent-filter>
    <action android:name="android.intent.action.MAIN1" />
         <category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

经过

<activity android:name=".NextActivity"></activity>
