Android基于ListView实现类似QQ空间的滚动翻页与滚动加载效果

listView.setOnScrollListener(new OnScrollListener() {
  //添加滚动条滚到最底部，加载余下的元素
  @Override
  public void onScrollStateChanged(AbsListView view, int scrollState) {
    if (scrollState == OnScrollListener.SCROLL_STATE_IDLE) {
      loadRemnantListItem();
    }
  }
  @Override
  public void onScroll(AbsListView view, int firstVisibleItem, int visibleItemCount, int totalItemCount) {}
  });
listView.setOnItemSelectedListener(new OnItemSelectedListener() {
  //按键选择List中的item，焦点落在最下面的view上加载余下的item
  @Override
  public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
    if(footerView == view) {
      loadRemnantListItem();
      listView.setSelection(position - 1);
    }
  }
  @Override
  public void onNothingSelected(AdapterView<?> parent) {}
  });
private void loadRemnantListItem() {//滚到加载余下的数据
  //动态的改变listAdapter.getCount()的返回值
  //使用Handler调用listAdapter.notifyDataSetChanged();更新数据
}

private void loadRemnantListItem() {//滚到加载余下的数据
  //重新listView.setAdapter(newsAdapter);
  //使用Handler调用listAdapter.notifyDataSetChanged();更新数据
}
