Method Detail

getPositionById

int getPositionById(ID id)

Returns:

Position of list item which contains element with given ID, or NO_POSITION if element with given ID is not part of the list.
Note, that there can be several elements inside single list item, but we only need to know list item position, so we can scroll to it if required.

getViewById

android.view.View getViewById(ID id)

Returns:

View for given element ID, or null if view is not found.
Note, that it is safe to return null if view is not found on the screen, list view will be automatically scrolled to needed position (as returned by getPositionById(Object)) and this method will be called again.
