Filter with multiple selection mode

Hi, I am using the Filter feature within Multiple Selection. They work fine separately, but there are issue which can’t persist selected item across filtering. for eg, if I select several items, then type a keyword for filter, then select some new items, then clear keyword. What I expected is the method getSelectedPositions() should return exactly index of selected items. Am i wrong in this situation? Could you please guide me how to achieve this ?

@IHNEL, what I can suggest is to override FlexibleAdapter method toggleSelection (I guess you call this method when user clicks on ViewHolder), so you can save and remove your own selection as item reference in your own Set (not List), and have a method called getSelectedItems() which returns always the list of the overall selections between the filters. Also you need to override properly the method isSelected() so that it will not check the list of position but the set of items you saved.

I think it should work.

The Adapter is saving the positions of the current list, not the references of the items. I don’t know if it’s better or worst to have item references against positions.

thank you @davideas. Seems this is the only way, I will do this
