Make sure we can get to the item

UiObject ListViewItem = view.getchildbyinstance (

New Uiselector (). Text (text), 0);

We need to make sure that the item exists (visible)

if (! ( Result && listviewitem.exists ())) {

Return Geterrorresult ("Could not scroll element into view:" + text);

}

return Getsuccessresult (Result);

} catch (Final Uiobjectnotfoundexception e) {

}

}

In Uiautomator, it is sometimes necessary to find an item in a scrolling list, and this item is in a variable position, and we can find the control of a particular text by Uiscrollable Scrollto. And the bootstrap of this scrollto is to encapsulate such a demand.

First, you determine whether the control is scrollable, and then create the Uiscrollable object, because the default scrolling style is vertical, and if you need horizontal orientation, set the orientation to horizontal.

View.setashorizontallist ();

Then roll the scroll control to the beginning, then set the maximum search range to 100 times, because it is impossible to search forever. And then start calling

View.scrolltextintoview (text);

Start scrolling, and finally confirm whether you want to scroll to set the goal:

View.waitforexists (5000);

Because there may be a flush to the time, the calling method then passes in the time 5 seconds.

UiObject ListViewItem = view.getchildbyinstance (

New Uiselector (). Text (text), 0);

Finally, check the result, get the object that made text, determine whether it exists and return the corresponding result to the client.
