Android无线测试之—UiAutomator UiScrollable API介绍七

滑动到某个对象

一、滑动到某个对象相关API

返回值	API	描述
boolean	scrollIntoView(UiSelector selector)	滑动到条件元素所在位置，并且尽量让其居于屏幕中央
boolean	scrollIntoView(UiObject obj)	滑动到对象所在位置，并且尽量让其居于屏幕中央
boolean	scrollTextIntoView(String text)	滑动到文本对象所在位置，并且尽量让其居于屏幕中央
boolean	scrollDescriptionIntoView(String text)	滑动到文本描述对象所在位置，并且尽量让其居于屏幕中央
boolean	scrollToBeginning(int maxSwipes)	自定义扫动次数，滑动到开始位置
boolean	scrollToBeginning(int maxSwipes, int steps)	自定义扫动次数与步长，滑动到开始位置
boolean	scrollToEnd(int maxSwipes)	自定义扫动次数，滑动到结束位置
boolean	scrollToEnd(int maxSwipes, int steps)	自定义扫动次数与步长，滑动到结束位置

说明：所有函数都是先在当前界面查找是否有要找的对象，没找到则先向上滑动指定的扫动次数，然后再向下滑动的同时查找有没有这个对象，但也仅向下滑动指定的扫动次数，找不到则会报错。

        sleep(2000);

        UiScrollable scroll=new UiScrollable(new UiSelector().className("android.widget.ListView"));

        scroll.scrollToBeginning(50);
        sleep(3000);

        UiSelector testview=new UiSelector().text("test");
        scroll.scrollIntoView(testview);
        sleep(3000);

        scroll.scrollToBeginning(50, 5);
        sleep(3000);

        UiObject test=new UiObject(testview);
        scroll.scrollIntoView(test);
        sleep(3000);

        scroll.scrollToEnd(50);
        sleep(3000);

        scroll.scrollTextIntoView("test");
        sleep(3000);

        scroll.scrollToEnd(50,5);
