示例1: getChildElements
import android.support.test.uiautomator.UiSelector; //導入方法依賴的package包/類
public ArrayList<UiObject> getChildElements(final UiSelector sel) throws UiObjectNotFoundException {
boolean keepSearching = true;
final String selectorString = sel.toString();
final boolean useIndex = selectorString.contains("CLASS_REGEX=");
final boolean endsWithInstance = endsWithInstancePattern.matcher(selectorString).matches();
Logger.debug("getElements selector:" + selectorString);
final ArrayList<UiObject> elements = new ArrayList<UiObject>();
// If sel is UiSelector[CLASS=android.widget.Button, INSTANCE=0]
// then invoking instance with a non-0 argument will corrupt the selector.
//
// sel.instance(1) will transform the selector into:
// UiSelector[CLASS=android.widget.Button, INSTANCE=1]
//
// The selector now points to an entirely different element.
if (endsWithInstance) {
Logger.debug("Selector ends with instance.");
// There's exactly one element when using instance.
UiObject instanceObj = Device.getUiDevice().findObject(sel);
if (instanceObj != null && instanceObj.exists()) {
elements.add(instanceObj);
}
return elements;
}
