Blackberry引路蜂地圖開發示例：本地查詢

本地查詢可以查詢指定區域內諸如賓館，郵局等用戶感興趣的地方。其使用方法和地址查詢非常類似。
下面示例查詢32.0616667, 118.7777778為中心點一定區域內賓館的信息

}本地查詢方法
public void getLocations(String address,int start,GeoLatLng center,GeoBounds bound, IGeocodingListener listener);
指定中心點和查詢區域。本地查詢可以多次返回結果，start為查詢結果起始順序，每次返回結果在SearchOptions 中定義，缺省每次返回４個。
上述結果返回內容為，具體結果可能不同。www.2cto.com
