When i look at the sample from the seperatedlistadapter i see this:
# @Override
# public void onCreate(Bundle icicle) {
# super.onCreate(icicle);
#
# List<Map<String,?>> security = new LinkedList<Map<String,?>>
();
# security.add(createItem("Remember passwords", "Save
usernames and passwords for Web sites"));
# security.add(createItem("Clear passwords", "Save usernames
and passwords for Web sites"));
# security.add(createItem("Show security warnings", "Show
warning if there is a problem with a site's security"));
#
# // create our list and custom adapter
# SeparatedListAdapter adapter = new SeparatedListAdapter
(this);
# adapter.addSection("Array test", new ArrayAdapter<String>
(this,
# R.layout.list_item, new String[] { "First item", "Item
two" }));
# adapter.addSection("Security", new SimpleAdapter(this,
security, R.layout.list_complex,
# new String[] { ITEM_TITLE, ITEM_CAPTION }, new int[]
{ R.id.list_complex_title, R.id.list_complex_caption }));
#
# ListView list = new ListView(this);
# list.setAdapter(adapter);
# this.setContentView(list);
#
# }
so every section is using a different layout file. So why doestn't
this work with me? :(
If you agree I will give you my source code?
