推荐大家一个好用的实现分页加载和下拉刷新Android工具包

PageAndPullToRefresh工具包

分页加载和下拉刷新，几行代码完全搞定

具体实现方法如下：

实例化一个PageAndRefreshListView，

可以通过layout来加载

mListView = (PageAndRefreshListView) view.findViewById(R.id.balance_page_list);

给ListView设置adapter ，这个adapter需要继承PageAndRefreshBaseAdapter

示例如下：

adapter = new BalanceInfoAdapter(mContext, new BalanceDataReuqest(mContext, map));mListView.setAdapter(adapter);

adapter 示例：

public class BalanceInfoAdapter extends PageAndRefreshBaseAdapter {private LayoutInflater mInflater;public BalanceInfoAdapter(Context context,PageAndRefreshRequestService requestService) {super(requestService);mInflater = LayoutInflater.from(context);}class ViewHolder {public TextView bl_time_tv;public TextView bl_comefrom_tv;public TextView bl_income_tv;public TextView bl_sumcount_tv;}@Overridepublic View getView(int position, View convertView, ViewGroup parent) {ViewHolder holder = null;if (convertView == null) {holder = new ViewHolder();convertView = mInflater.inflate(R.layout.balance_list_item, null);holder.bl_time_tv = (TextView) convertView.findViewById(R.id.bl_time_tv);holder.bl_comefrom_tv = (TextView) convertView.findViewById(R.id.bl_comefrom_tv);holder.bl_income_tv = (TextView) convertView.findViewById(R.id.bl_income_tv);holder.bl_sumcount_tv = (TextView) convertView.findViewById(R.id.bl_sumcount_tv);convertView.setTag(holder);} else {holder = (ViewHolder) convertView.getTag();}BalanceInfo data = (BalanceInfo) getItem(position);if (data != null) {holder.bl_time_tv.setText(data.getCreateTime());holder.bl_comefrom_tv.setText(data.getPaymentTypeName());holder.bl_income_tv.setText(data.getCount());holder.bl_sumcount_tv.setText(data.getLeftCount());}return convertView;}}

实例化 PageAndRefreshBaseAdapter需要传递一个实现了PageAndRefreshRequestService接口的对象，该对象实现数据的获取与分页刷新机制，具体代码如下：

public class BalanceDataReuqest implements PageAndRefreshRequestService {private PageAndRefreshRequestCallBack mCallBack;private int page;private Context mContext;private Map map = new HashMap();private Handler handler = new Handler() {@SuppressWarnings("unchecked")@Overridepublic void handleMessage(Message msg) {switch (msg.what) {// 模拟请求结果，一次成功，一次失败，循环case 1:mCallBack.onRequestComplete((List) msg.obj,msg.arg1);break;default:break;}super.handleMessage(msg);}};public BalanceDataReuqest(Context context, Map map) {mContext = context;this.map = map;}@Overridepublic void sendRequest(int page, PageAndRefreshRequestCallBack listener) {if (mCallBack == null) {mCallBack = listener;}this.page = page;map.put("pageNum", page + "");map.put("pageSize", "30");// 此处使用线程模拟数据请求(网络或数据库)过程getData();}private void getData(){//自定义获取网络数据//通过Handler方式将页总数以及数据传递到主线程msg.what = 1;msg.obj = mdatas;msg.arg1 = totalPage;handler.sendMessage(msg);}}

至此，就完成了这个开源包的使用，如题效果如图：
