Android - Add an item from one ListView to another ListView?

问题

I have an app that shows news from a RSS feed. There is ListView-1 which loads the news and when you click on an item(news), it shows only the selected news in a seperated xml layout. On the ActionBar for the single news item layout, user can click on Add to Favourites.

I have another activity and layout file and a listview just for Favourites. How can I copy an item from one listview to another?

So, the user can add news from main ListView-1 to another list called ListView-2.

I cannot use intents for sending one list item. I have been thinking of using SharedPreferences to share an ArrayList, but something else needs to be the solution.

回答1:

You don't need intents, just separate view and data, keep news in the singleton class, for example NewsManager, and keep one list for all news, one for favourite news, and use favourite list in the ListView2 adapter
