如何在autoit的帮助下使用java从应用程序窗口中的列表中获取只读文本？

我打开了一个应用程序窗口。此窗口包含连接列表。我想使用java在autoIt的帮助下，从列表中唯一地检索处于只读状态的文本（即连接名）。我在列表中有两个连接。
对于这个项目，我使用的工具和技术如下：
1） JavaSE8
2） AutoIt

尽管包含连接列表的窗口具有唯一ID，但列表中的单个元素没有任何ID。 因此，按ID搜索和获取所需的唯一文本不是一个选项。 我使用了autoIt的方法来获得期望的结果。 在autoIt的帮助下，在java中使用上述方法，我成功地使用了方法，即controlListViewSelectClear（）、controlListViewSelectAll（）。 但是我得到了方法的错误，即controlListViewGetItemCount（），controlListViewFindItem（），controlListViewIsSelected（）。还有方法，即controlListViewGetText（）

下面是代码示例及其输出：

public class TestAutoIt {

    /*Choose the 'JACOB' dll based on the JVM bit version.*/
    .
    .
    .
    final String APPLICATION_TITLE = "ABC";
    final String CONNECTION_NAME = "APP Connection 1";

    private AutoItX control;

    {
        /*Load the jacob dll.*/
        .
        .
        .
        control = new AutoItX();
    }

    public static void main(String[] args) {
        try {
            TestAutoIt obj = new TestAutoIt();

            /*Returns the ControlRef# of the control that has keyboard focus within a specified window.*/
            String stringFocus = obj.control.controlGetFocus(APPLICATION_TITLE);
            System.out.println("stringFocus: " + stringFocus);
            if(stringFocus == "") {
                System.out.println("Unable to get keyboard focus.");
                throw new Exception("Unable to get keyboard focus.");
            }

            /*Get total connections present in the list*/
            System.out.println("totalConnections: " + obj.control.controlListViewGetItemCount(APPLICATION_TITLE, "", stringFocus)); // Error

             /*Check if required connection is present or not in the connection list. If present, returns index position of element else -1.*/
            System.out.println("Index of desired connection: " + obj.control.controlListViewFindItem(APPLICATION_TITLE, "", stringFocus, CONNECTION_NAME, "")); // Error

            /*Check if desired connection in the list is selected or not*/
            System.out.println("Connection selected: " + obj.control.controlListViewIsSelected(APPLICATION_TITLE, "", stringFocus, CONNECTION_NAME)); // Error

            /*Get text of required connection*/ // not working
            obj.control.sleep(2000);
            System.out.println("controlListViewGetText(APPLICATION_TITLE, \"\", stringFocus, \"\", \"\"): " + obj.control.controlListViewGetText(APPLICATION_TITLE, "", stringFocus, "", ""));
            System.out.println("controlListViewGetText(APPLICATION_TITLE, \"\", stringFocus, \"0\", \"\"): " + obj.control.controlListViewGetText(APPLICATION_TITLE, "", stringFocus, "0", ""));
            System.out.println("controlListViewGetText(APPLICATION_TITLE, \"\", stringFocus, \"0\", \"0\"): " + obj.control.controlListViewGetText(APPLICATION_TITLE, "", stringFocus, "0", "0"));
            System.out.println("controlListViewGetText(APPLICATION_TITLE, \"\", stringFocus, \"0\", \"1\"): " + obj.control.controlListViewGetText(APPLICATION_TITLE, "", stringFocus, "0", "1"));
            System.out.println("controlListViewGetText(APPLICATION_TITLE, \"\", stringFocus, \"1\", \"\"): " + obj.control.controlListViewGetText(APPLICATION_TITLE, "", stringFocus, "1", ""));
            System.out.println("controlListViewGetText(APPLICATION_TITLE, \"\", stringFocus, \"1\", \"1\"): " + obj.control.controlListViewGetText(APPLICATION_TITLE, "", stringFocus, "1", "1"));
            obj.control.sleep(2000);

            /*Change view to list view*/ // not working
            obj.control.controlListViewSelectViewChange(APPLICATION_TITLE, "", stringFocus, "list"); // No error but there was no change in the view

            /*Clear list selection*/
            obj.control.controlListViewSelectClear(APPLICATION_TITLE, "", stringFocus); // Worked successfully

            /*Select All*/
            obj.control.controlListViewSelectAll(APPLICATION_TITLE, "", stringFocus, "0", "1"); // Worked successfully

        } catch (Exception e) {
            System.out.println("Exception: " + e);
            e.printStackTrace();
        }
    }
}

上述代码的输出如下：

1） （输出1）我得到了正确的输出，即“获取列表中存在的总连接数”的输出2
2） （输出2）现在，为了检查所需的连接是否存在于列表中，我总是得到-1的输出。即使我给出了正确的连接名称，我也只得到-1的输出
谁能告诉我我做错了什么
3） （输出3）检查是否选择了列表中所需的连接， 我总是得到1的输出。在这里，即使我给出了错误的连接名称，我也只得到1的输出，即选择了所需的连接，这是错误的
谁能告诉我我做错了什么
