如何执行点击开关按钮（打开/关闭）的操作？

Question

我正在尝试在智能手机Android 7.1上测试以下代码，以尝试单击切换按钮（打开 / 关闭）：

但是什么也没发生，尽管这表明是成功的。

如何解决这个问题？

private void iteratorTXDM(AccessibilityNodeInfo info) {
    boolean found = false;
    List<AccessibilityNodeInfo> node = info.findAccessibilityNodeInfosByViewId("android:id/switch_widget");
    if (node != null) {
        for (AccessibilityNodeInfo element : node) {
            element.performAction(AccessibilityNodeInfo.ACTION_CLICK);
            System.out.println("The element was clicked!!");
        }
        //iteratorTXDM(getRootInActiveWindow());
        found = true;
        return;
    } else {
        for (int i = 0; i < info.getChildCount(); i++) {
            if (info.getChild(i) != null) {
                if (found) {
                    found = false;
                    break;
                }
                iteratorTXDM(info.getChild(i));
            }
        }
    }
    return;
}

private void click(){

    iteratorTXDM(source);
}

AccessibilityNodeInfo source;

@Override
public void onAccessibilityEvent(AccessibilityEvent event) {

    source = event.getSource();

    if (source == null) {
        return;
    }
}
