Change a list view through it's onItemListener

I made an onTouchListener to a list view that checks which item (string in my case) in that list was clicked and it's position. I want to take out that string of the list, so I made a method that gets the array adpter's string array and the poistion the list was touched and returns a new array that is the same but without the string that was touched. now I want to update the list view adapter to the new array, how do I do that? thanks

What you have to do is set a change notification to the array adapter via the BaseAdapter.notifyDatasetChanged. This will refresh the entire list view. Note: this must be called in the main thread.

EDIT:

To clear some confusion you have to first fetch the Adapter from your list view. This is done by calling myListView.getAdapter(). So you could do 

myListView.getAdapter().notifyDatasetChanged()

You should try to set the array in your adapter again.

listView.setAdapter(new YourAdapter(this, yourArray));

just call notifyDataSetChanged() on the adapter to reload it
