[置顶] android Listview分批加载+自动加载（附源码下载）

直接上代码，代码有注释：
public class TestForListviewActivity extends Activity implementsOnScrollListener {private ListView mListview = null;private View mFooterView;private PaginationAdapter mAdapter;private Handler handler=new Handler();private boolean isLoading;//表示是否正在加载private final int MAX_COUNT=35;//表示服务器上总共有MAX_COUNT条数据private final int EACH_COUNT=10;//表示每次加载的条数@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);mFooterView = getLayoutInflater().inflate(R.layout.loadmore, null);mListview = (ListView) findViewById(R.id.listview);mListview.addFooterView(mFooterView);// 设置列表底部视图List<News> news=new ArrayList<News>();mAdapter = new PaginationAdapter(news);;mListview.setAdapter(mAdapter);//设置setOnScrollListener会自动调用onscroll方法。mListview.setOnScrollListener(this);}public void onScroll(AbsListView view, int firstVisibleItem,int visibleItemCount, int totalItemCount) {if (firstVisibleItem+visibleItemCount==totalItemCount&&!isLoading) {//isLoading = true 表示正在加载，加载完毕设置isLoading =false；isLoading = true;//如果服务端还有数据，则继续加载更多，否则隐藏底部的加载更多if (totalItemCount<=MAX_COUNT) {//等待2秒之后才加载，模拟网络等待时间为2shandler.postDelayed(new Runnable() {public void run() {loadMoreData();}},2000);}else{if (mListview.getFooterViewsCount()!=0) {mListview.removeFooterView(mFooterView);}}}}public void onScrollStateChanged(AbsListView arg0, int arg1) {Log.i("onScrollStateChanged", arg1+"");}private void loadMoreData(){int count = mAdapter.getCount();for (int i = 0; i < EACH_COUNT; i++) {if (count+i<MAX_COUNT) {News item = new News();item.setTitle("Title" + (count+i));item.setContent("This is News Content" + (count+i));mAdapter.addNewsItem(item);}else{mListview.removeFooterView(mFooterView);}}mAdapter.notifyDataSetChanged();isLoading = false;}class PaginationAdapter extends BaseAdapter {List<News> newsItems;public PaginationAdapter(List<News> newsitems) {this.newsItems = newsitems;}public int getCount() {return newsItems==null?0:newsItems.size();}public Object getItem(int position) {return newsItems.get(position);}public long getItemId(int position) {return position;}public void addNewsItem(News newsitem) {newsItems.add(newsitem);}public View getView(int position, View convertView, ViewGroup parent) {if (convertView == null) {convertView = getLayoutInflater().inflate(R.layout.list_item,null);}// 新闻标题TextView tvTitle = (TextView) convertView.findViewById(R.id.newstitle);tvTitle.setText(newsItems.get(position).getTitle());// 新闻内容TextView tvContent = (TextView) convertView.findViewById(R.id.newscontent);tvContent.setText(newsItems.get(position).getContent());return convertView;}}}
