Appium: How to iterate over a listview of unknown length?

I have a list view with a hierarchy I theoretically have no knowledge of. I am attempting to accept a String array and create MobileElements for each string in it, but due to the way I've automated (PageFactory) defining my elements via annotations, they cannot use variables. I also don't know that it's valid or proper to define my annotations inside a method.

The code I've written, which obviously does not compile follows:

public void selectLocation(String[] location) {

    List<MobileElement> locationsList = new ArrayList<>();
    for(int i = 0; i < location.length; i++) {

        @iOSFindBy(accessibility = location[i])
        @AndroidFindBy(xpath = "//android.widget.TextView[@text='" + location[i] + "']")
        locationsList.add(i);
    }
    for (int i = 0; i < location.length; i++) {
        locationsList.get(i).click();
    }
}

I'm assuming the proper way to do this is wholly different from the way I've implemented.

My list hierarchy is similar to the following; my end point could vary depending on the branch I go down:

Continent 1
- City 1
  - Room 1
  - Room 2
- City 2
  - Building 1
    - Room 1
    - Room 2
  - Building 2
    - Room 1
    - Room 2

Solution

I now look for a matching element. If I don't find it, I swipe further into the list. If the element doesn't exist I obviously run into problems, but not really an issue in my case since that’d be a failing test.

while (!driver.findElementById(currentLocation).isDisplayed()) {
   driver.swipe(startX, startY, startX, endY, 100);
}
driver.findElementById(currentLocation).click();

Yes, I also realize .swipe() is deprecated, but it still works for me and I'd rather not rewrite all my code with TouchActions until necessary.
