传递与填充数据
- 真实距离不好计算
不在 onCreateView做初始化工作，放到 onActivityCreated 中。在 onCreateView 中只保存一个 rootView 的引用，注意要再 onDestoryView 中把它设为 null。

public class SimpleFragment extends TaskFragment implements OnLoadDataListener
{
    private ViewState mViewState = null;
    private View mRootView;
    private LoadDataTask mLoadDataTask;
    private ProductEntity mProduct;
    @Override
    public void onAttach(Activity activity) 
    {
        super.onAttach(activity);
    }
    @Override
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setHasOptionsMenu(true);
        setRetainInstance(true);
    }
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
    {
        mRootView = inflater.inflate(R.layout.fragment_simple, container, false);
        return mRootView;
    }
    @Override
    public void onActivityCreated(Bundle savedInstanceState)
    {
        super.onActivityCreated(savedInstanceState);
        // load and show data
        if(mViewState==null || mViewState==ViewState.OFFLINE)
        {
            loadData();
        }
        else if(mViewState==ViewState.CONTENT)
        {
            if(mProduct!=null) renderView();
            showContent();
        }
        else if(mViewState==ViewState.PROGRESS)
        {
            showProgress();
        }

查文档，决定比查博客高效、准确、可靠。
long vs double ？？？
百度地图，经纬度到地址的转换（坑爹的 api，竟然没有查询功能，我在 IDE 里输了，看到包名，再去找，真他妈坑）
还有计算距离

        final GeoCoder geoCoder = GeoCoder.newInstance();
        ReverseGeoCodeOption option = new ReverseGeoCodeOption();
        option.location(new LatLng(cleaner.latitude, cleaner.longitude));
        geoCoder.reverseGeoCode(option);
        geoCoder.setOnGetGeoCodeResultListener(new OnGetGeoCoderResultListener() {
            @Override
            public void onGetReverseGeoCodeResult(ReverseGeoCodeResult reverseGeoCodeResult) {
                locationTextView.setText(reverseGeoCodeResult.getAddress());
                geoCoder.destroy();
            }
            @Override
            public void onGetGeoCodeResult(GeoCodeResult arg0) {
            }
        });

待解决的问题
- start activitiy out activity??? 1
- 距离的显示，米还是公里，直接用公里，精确度是100米...还是分米和公里两种吧，0.1公里，不好，格式化小数里面的学问也不小啊，new DecimalFormat("#.##").format(1.199); //"1.2"``String.format("%.2f", value) ;3~~~~~
- 头像的展示 4
- 详情页的可切换 2 ~
- 详情页位置的显示还是不够正常；难道是顺序的问题，？？？~

还把 pk 写错导致经纬度一直没能更新到服务器上！！！
