Answer 1

A list view can dynamically load items using an Adapter. The development documents have a great tutorial on how to use a ListView and GridView. Basically you set the adapter of your ListView with a collection of objects. Then when you update the objects, you can call notifyDataSetChanged.

ArrayList myitems = new ArrayList();
myitems.add("Hello");
myitems.add("Line 2");
myitems.add("Another line");

ListView listView = (ListView)findViewById(R.id.mylistview);
ArrayAdapter adapter = new ArrayAdapter(this, R.layout.list_item, myitems));
listView.setAdapter(adapter);

myitems.add("Goodbye");
adapter.notifyDataSetChanged();

R.id.mylistview is the id I gave my ListView

R.layout.list_item is the layout for each list item. It's just a simple TextView
