MapView，DataFramework(MapView, DataFramework)

我是一个新手android开发者，现在我正在使用Mapview。我想在地图中显示基于他的纬度和经度的不同种类的叠加。

我用sqlite创建了一个数据库，保存在文件夹资产上。这是我的tables.xml（对不起，但字段是西班牙语）

太简单了。这一刻我不需要更多。在thar之后我创建了一个名为MapaActivity的Activity，我绘制了mapView。这里我有2个问题，第一个，我的mapView必须是TapControlledMapView，因为我想使用方法onsingleTapListener，但我不能，它导致FC总是，我不知道为什么！

第二个问题是当我想从数据库中提取实体列表（列表

List<Entity> puestos = Lists.newArrayList(); DataFramework db = null; try { db = DataFramework.getInstance(); db.open(this, getPackageName()); puestos = db.getEntityList("puestos", "latitud < " + maxLatitud + " and latitud > " + minLatitud + " and longitud < " + maxLongitud + " and longitud > " + minLongitud); } catch (Exception e) { e.printStackTrace(); } finally { db.close(); }

什么都没发生，puestos总是空的。

有任何想法吗？？？

谢谢！

i am a newbie android developper and now i'm working with Mapview. I want to show in a map differents kinds of Overlays base on his latitude and longitude.

I have created a data base with sqlite, saved on the folder assets. This is my tables.xml (sorry but the fields are in spanish)

Is too simple. I dont need more for this moment. After thar i've created an Activity called MapaActivity where i draw my mapView. Here i have 2 problems, first one, my mapView has to be a TapControlledMapView because i want to use the method onsingleTapListener, but i cant, its caused FC always and i dont why!

The second trouble is when i want to extract from the database a list of Entitys (List

List<Entity> puestos = Lists.newArrayList(); DataFramework db = null; try { db = DataFramework.getInstance(); db.open(this, getPackageName()); puestos = db.getEntityList("puestos", "latitud < " + maxLatitud + " and latitud > " + minLatitud + " and longitud < " + maxLongitud + " and longitud > " + minLongitud); } catch (Exception e) { e.printStackTrace(); } finally { db.close(); }

Nothing happens, puestos is always empty.

Any ideas???

Thanks!
