My question is simple: How do I use long click to let the users select items from the ListView
? So far, I only know how to detect 'short' clicks and take appropriate actions.
Also, I would like to display a check mark on the selected item. How can that be done ?
Simple : OnLongClickListener
Then you need to manually remember what is selected or not. You need to notify the list from the changes and do something in the getView method of you adapter.
It would be a good practice to use the Contextual ActionBar mode to interact with all item at once, see here.
