Is it possible to update a SimpleAdapter? I have a list of data and a footer that says \"See Next Results\" When that list item is clicked I capture the event and get new d

Answer 1

I was not able to get notifyDataSetChanged() to work on updating my SimpleAdapter, so instead I tried first removing all views that were attached to the parent layout using removeAllViews(), then adding the ListView, and that worked, allowing me to update the UI:

LinearLayout results = (LinearLayout)findViewById(R.id.results);
ListView lv = new ListView(this);
ArrayList> list = new ArrayList>();
SimpleAdapter adapter = new SimpleAdapter( this, list, R.layout.directory_row, 
                    new String[] { "name", "dept" }, new int[] { R.id.name, R.id.dept } );

for (...) { 
    HashMap map = new HashMap();
    map.put("name", name);
    map.put("dept", dept);
    list.add(map);
}

lv.setAdapter(adapter);
results.removeAllViews();     
results.addView(lv);
