我正在使用UI自动机编写UI测试并遇到了一个问题,我试图滚动到NumberPicker的开头,但是当使用ScrollToBeginning或FlingToBeginning执行不同数量的步骤时,NumberPicker只会向上滚动两个元素,然后停止滚动。有没有理由这种行为一直在发生,有没有办法解决或解决它?

使用辅助方法解决方法,如下所示:
/**
* Launches an app by it's name.
*
* @param nameOfAppToLaunch the localized name, an exact match is required to launch it.
*/
protected static void launchAppCalled(String nameOfAppToLaunch) throws UiObjectNotFoundException {
UiScrollable appViews = new UiScrollable(new UiSelector().scrollable(true));
// Set the swiping mode to horizontal (the default is vertical)
appViews.setAsHorizontalList();
appViews.scrollToBeginning(10); // Otherwise the Apps may be on a later page of apps.
int maxSearchSwipes = appViews.getMaxSearchSwipes();
UiSelector selector;
selector = new UiSelector().className(android.widget.TextView.class.getName());
UiObject appToLaunch;
// The following loop is to workaround a bug in Android 4.2.2 which
// fails to scroll more than once into view.
for (int i = 0; i < maxSearchSwipes; i++) {
try {
appToLaunch = appViews.getChildByText(selector, nameOfAppToLaunch);
if (appToLaunch != null) {
// Create a UiSelector to find the Settings app and simulate
// a user click to launch the app.
appToLaunch.clickAndWaitForNewWindow();
break;
}
} catch (UiObjectNotFoundException e) {
System.out.println("Did not find match for " + e.getLocalizedMessage());
}
for (int j = 0; j < i; j++) {
appViews.scrollForward();
System.out.println("scrolling forward 1 page of apps.");
}
}
}
