public class ListViewExample extends Activity {

    private String[] list1 = { "Icon", "Icon Creator", "Image", "Image Creator" };

    private ListView lister1;

    Button btn_add;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        lister1 = (ListView) findViewById(R.id.ListView1);
    btn_add =(Button)findViewById(R.id.btn_add);
    String[] list2 = { "nikunj", "patel", "hi", "this" };
    ItemsAdapter itemsAdapter = new ItemsAdapter(ListViewExample.this,
            R.layout.list, list2);
    lister1.setAdapter(itemsAdapter);
    btn_add.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            // Perform action on click
            String[] list2 = { "nikunj", "patel", "hi", "this" };
            ItemsAdapter itemsAdapter = new ItemsAdapter(ListViewExample.this,
                    R.layout.list, list2);
            lister1.setAdapter(itemsAdapter);

        }
    });

You can add a "footer view" which will always show at the bottom of your list:

View footerView = getLayoutInflater().inflate(R.layout.footer_layout, lister1, false);
lister1.addFooterView(footerView);

When you add new item in your dataSource you will update adapter by

itemsAdapter.notifyDataSetChanged();
