Question

Well it seem i am having quite some trouble with my arrayadapter of strings. It seem there is no real way to only modify an item in the list. I had to delete and insert back the string to see changes appears. So my question is Why is the ArrayAdapter doesn’t have the set method like arraylist do ? Why it do not have any easy way to change an element in the list ? In order to change an element is is an option to create a custom adapter based on BaseAdapter ?

Answer 1

lets see this sample code:

ArrayList<String> items = new ArrayList<String>();

MyAdapter myAdapter = new MyAdapter(items, context);

you can modify an item using:

// items.set(index,object);

items.set(0,"Hello New Value");

myadapter.notifyDataSetChanged();// to tell the adapter there's new values has been changed
