问题 I have created a listview with textview and checkbox. However after scrolling the list down(or up) all the checked items in the list get unselected. How to make the checked checkboxes retain their state after scrolling? 回答1: ListView recycles the views every time it is scrolled. That's why the Check-boxes does not retain their states.

问题 I'm suffering from the same issue as this question: Wrong item checked when filtering ListView in android As suggested in the above question, I have an Hashset holding all the selectedIds, but I can't figure out how to use it when the cursor is repopulating the checked items.

So that class serves as the source for my adapter. I want to use SwipeRefreshLayout for refreshing the adapter and so the ListView. DogActivity is an Observer of SynchDogs so that DogActivity implements an update method that is called when new data is ready.
