Android: how to remove an item from a listView and arrayAdapter

Question

I have a collection of items in an ArrayList. I add them to a customer adapter as follows:

this.m_adapter = new MyAdapter(this, R.layout.myitem,
    itemCart.m_items);

I have a delete button for each of these items in my list, but I am not sure how to connect the delete button's onClick() with the original item in the ArrayList. Can someone please explain how to do this or point me to a tutorial where I can read up on this? Non-sarcastic/non-condescending responses are greatly appreciated.

Answer 1

You can call the remove() method on your ArrayList

itemCart.m_items.remove(<index of element to remove>);
this.m_adapter.notifyDataSetChanged();

And then you need to call notifyDataSetChanged(); on your adapter to update the ListView
