Blackberry引路蜂map开发示例：本地查询

本地查询可以查询指定区域内诸如宾馆，邮局等用户感兴趣的地方。其使用方法和地址查询非常类似。
下面示例查询32.0616667, 118.7777778为中心点一定区域内宾馆的信息

本地查询方法
public void getLocations(String address,int start,GeoLatLng center,GeoBounds bound, IGeocodingListener listener);
指定中心点和查询区域。本地查询可以多次返回结果，start为查询结果起始顺序，每次返回结果在SearchOptions 中定义，缺省每次返回４个。
上述结果返回内容为，具体结果可能不同。
