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;
	}

	@Override
	public 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")
		@Override
		public 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;
	}

	@Override
	public 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：
