然后是主代码：
public class MainActivity extends ListActivity { private ListView mListView; private CustomAdapter mAdapter; private int mScrollState; private View mFooter; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); //获取ListView mListView = getListView(); //根据footer.xml描述创建View mFooter = getLayoutInflater().inflate(R.layout.footer, null); // 在ListView底部添加正在加载视图 //注意：addFooterView方法需要在调用setListAdapter方法前调用！ mListView.addFooterView(mFooter); mAdapter = new CustomAdapter(); setListAdapter(mAdapter); //给ListView添加滚动监听器 mListView.setOnScrollListener(new AbsListView.OnScrollListener() { @Override public void onScrollStateChanged(AbsListView view, int scrollState) { //记录当前状态 mScrollState = scrollState; } @Override public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) { // 可视的最后一个列表项的索引 int lastVisibleItem = firstVisibleItem + visibleItemCount - 1; //当列表正处于滑动状态且滑动到列表底部时，执行 if (mScrollState != AbsListView.OnScrollListener.SCROLL_STATE_IDLE && lastVisibleItem == totalItemCount - 1) { // 执行线程，模拟睡眠5秒钟后添加10个列表项 new Thread() { private Handler handler = new Handler() { @Override public void handleMessage(Message msg) { super.handleMessage(msg); //增加Item数量 mAdapter.count += 10; //通知数据集变化 mAdapter.notifyDataSetChanged(); } }; @Override public void run() { super.run(); try { sleep(5000); handler.sendEmptyMessage(0); } catch (InterruptedException e) { e.printStackTrace(); } } }.start(); } } }); } private class CustomAdapter extends BaseAdapter { // 初始列表项数量 int count = 20; @Override public int getCount() { return count; } @Override public Object getItem(int position) { return position; } @Override public long getItemId(int position) { return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { TextView result = (TextView) convertView; //动态创建TextView添加早ListView中 if (result == null) { result = new TextView(MainActivity.this); result.setTextAppearance(MainActivity.this, android.R.style.TextAppearance_Large); AbsListView.LayoutParams layoutParams = new AbsListView.LayoutParams (AbsListView.LayoutParams.FILL_PARENT, AbsListView.LayoutParams.WRAP_CONTENT); result.setLayoutParams(layoutParams); result.setGravity(Gravity.CENTER); } result.setText("第 " + (position + 1)+"行"); return result; } } }效果预览：
