How to get all text having certain pattern in UIAutomator

I have a list of contacts which is scrollable. I want to get all contacts starting with +880 while scrolling. How can I use regex here?
Here is my code

     ui_str = 'new UiScrollable(new UiSelector().scrollable(true).instance(0)).getChildByText(new UiSelector().className("android.widget.TextView"), "+880")'
     current_group_members = admin_device.driver.find_elements_by_android_uiautomator(ui_str)

I’ve also resource id of each element com.test.communicator:id/phoneNumberTxt. Can I get all elements with this id?
I’ve tried to use find_elements_by_id but It gets only visible items. I need all elements in the list.
