使用地址详细信息调用 Blackberry Map 应用程序

发布于 2024-10-30 22:44:51 字数 474 浏览 2 评论 0原文

我正在使用 4.6 版本的黑莓操作系统。

我尝试使用以下命令调用地图应用程序：

Invoke.invokeApplication(Invoke.APP_TYPE_MAPS, new MapsArguments(MapsArguments.ARG_LOCATION_DOCUMENT, document));

这对于示例文档来说效果很好，例如：

            String document = "<lbs>" + "<location lon='-8030000' lat='4326000' label='Kitchener, ON' description='Kitchener, Ontario, Canada' />" + "</lbs>";

我的问题是：如果我不知道我要检查的位置的坐标，如何构建这样的文档？我只知道地址...

I am working with version 4.6 of the blackberry OS.

I am attempting to invoke the Maps application using the following:

Invoke.invokeApplication(Invoke.APP_TYPE_MAPS, new MapsArguments(MapsArguments.ARG_LOCATION_DOCUMENT, document));

This works fine for an example document such as:

            String document = "<lbs>" + "<location lon='-8030000' lat='4326000' label='Kitchener, ON' description='Kitchener, Ontario, Canada' />" + "</lbs>";

My question is: how can I construct such a document if I do not know the coordinates of the location I am trying to inspect? I only know the address...

根据此文档，支持地址、城市、邮政编码和区域属性。这行得通吗？

如果这不起作用，您需要使用 Locator 类来获取位置信息。但它需要起始坐标。文档第 25 页的代码:

// Create an javax.microedition.location.AddressInfo  object
AddressInfo ai = new AddressInfo();

// Set the fields of the AddressInfo Object
ai.setField(AddressInfo.STREET, “main street”);
ai.setField(AddressInfo.CITY, “Toronto”);
ai.setField(AddressInfo.STATE, “Ontario”);
ai.setField(AddressInfo.POSTAL_CODE, “XXX XXX”);
ai.setField(AddressInfo.COUNTRY, “Canada”);

// Create a Coordinates object that the location-based services locator server
//   uses as a starting location to search for location 
//   information for an address.
Coordinates co = new Coordinates(45.423488, -75.697929, 0);

// Create a Locator object.
Locator lo = new Locator();

// Invoke Locator.geocode(AddressInfo address, Coordinates startCoords).
Enumeration en = lo.geocode(ai, co);

According to this document, <location> supports an address, city, postal code, and region attributes. Would this work?

If that doesn't work, you'll need to use the Locator class to get the location information. It needs starting coordinates though. Code from page 25 of the documentation:

// Create an javax.microedition.location.AddressInfo  object
AddressInfo ai = new AddressInfo();

// Set the fields of the AddressInfo Object
ai.setField(AddressInfo.STREET, “main street”);
ai.setField(AddressInfo.CITY, “Toronto”);
ai.setField(AddressInfo.STATE, “Ontario”);
ai.setField(AddressInfo.POSTAL_CODE, “XXX XXX”);
ai.setField(AddressInfo.COUNTRY, “Canada”);

// Create a Coordinates object that the location-based services locator server
//   uses as a starting location to search for location 
//   information for an address.
Coordinates co = new Coordinates(45.423488, -75.697929, 0);

// Create a Locator object.
Locator lo = new Locator();

// Invoke Locator.geocode(AddressInfo address, Coordinates startCoords).
Enumeration en = lo.geocode(ai, co);
