无法使用 UIScrollable 和 UISelector 定位元素

Question

我正在使用此代码来选择元素

public static void swipe()

{

    MobileElement element = driver.findElementByAndroidUIAutomator(

                    "new UiScrollable(new UiSelector().class(\"android.widget.ImageView\")).getChildByText("

                    + "new UiSelector().resourceId(\"com.spotify.music:id/title\"), \"UnderCover\")");

    //Perform the action on the element

    System.out.println(element.getText()); //This would print - Unblock Me FREE

}

我把这个当作错误

io.appium.uiautomator2.common.exceptions.UiSelectorSyntaxException: Could not parse expression `new UiScrollable(new UiSelector().class("android.widget.ImageView")).getChildByText(new UiSelector().resourceId("com.spotify.music:id/title"), "UnderCover")`: UiScrollable has no suitable constructor with arguments [new UiSelector().class("android.widget.ImageView")]

at io.appium.uiautomator2.utils.UiExpressionParser.findConstructor(UiExpressionParser.java:232)

公共构造函数UIScrollable是：UiScrollable(UiSelector container);使用类似className的公共方法UiSelector：UiSelector className (String className); //or UiSelector className (Class<T> type);尝试new UiScrollable(new UiSelector().className("android.widget.ImageView"));代替new UiScrollable(new UiSelector().class("android.widget.ImageView"));
