UiScrollable在UiAutomator中無法按預期工作

Question

我是UIautomator編程的新手，需要使用滾動從設置中選擇選項“設備”。

這是我寫的代碼：

public class LaunchClass extends UiAutomatorTestCase {

    public static final UiSelector LAUNCHER_ITEM = new UiSelector().className(android.widget.TextView.class.getName());


    public void testDemo() throws UiObjectNotFoundException {
          //new UiObject(new UiSelector().text("Email")).clickAndWaitForNewWindow();

        getUiDevice().pressHome();
        UiObject settingsClick = new UiObject(new UiSelector().description("Settings. App. Item *23 of *24 on page *1."));    
        settingsClick.clickAndWaitForNewWindow();
        UiScrollable scroll = new UiScrollable(new UiSelector().scrollable(true));
        scroll.setAsVerticalList();
        sleep(5000);
        UiObject voiceButton = scroll.getChildByText(LaunchClass.LAUNCHER_ITEM, "Device");
        sleep(5000);
        voiceButton.clickAndWaitForNewWindow();

在執行此操作時，它會向下滾動，但不會選擇“設備”，我認為滾動可能比單擊速度慢，因此引入了睡眠-但這沒有好處。

這是我得到的錯誤：

testDemo錯誤：

如果有人能指出我在做什么錯，我將不勝感激，這是我第一次來，任何幫助將不勝感激。

看起來這里有兩件事：

1. 錯誤日志顯示您已經更改了代碼，但是沒有再次編譯它：)

   com.android.uiautomator.core.UiObjectNotFoundException: for text= "Voice"嗎？ -根據您的代碼，它應該已經代替了"Device"

2. 使用UiObject voiceButton = scroll.getChild(new UiSelector().className("android.widget.TextView").text("Device")); 而不是UiObject voiceButton = scroll.getChildByText(LaunchClass.LAUNCHER_ITEM, "Device"); 。

如果您擁有clickAndWaitForNewWindow()我真的不認為您需要sleep
