Question

I realize that similar questions have been asked before. My list is displayed using

setListAdapter(new ArrayAdapter<String>(this, R.layout.listlayout, names));

to refresh, previous answers have either been to use notifyDataSetChanged() or invalidate()
but to what !? I don’t appear to have anything to apply the method to.

Sorry if I’m being daft.

Answer 1

Store your ArrayAdapter somewhere. For example

adapter = new ArrayAdapter<String>(this, R.layout.listlayout, names)
setListAdapter(adapter);
...
adapter.notifyDataSetChanged();
