Question

我正在尝试调用黑莓地图并按地址标记位置。我尝试了以下示例代码

public class invokeMaps
{
    public invokeMaps ()
    {
        Landmark[] landMarks = new Landmark[3];

        AddressInfo addressInfo = new AddressInfo();
        addressInfo.setField(AddressInfo.STREET, "455 Phillip St");
        addressInfo.setField(AddressInfo.CITY, "Waterloo");
        addressInfo.setField(AddressInfo.STATE, "Ontario");

        landMarks[0] = new Landmark("AAA", "Description 1", null, addressInfo);

        QualifiedCoordinates coordinates =
          new QualifiedCoordinates(45.4, -75.1, 0, 0, 0);

        landMarks[1] = new Landmark("BBB", "Description 2", coordinates, null);

        coordinates = new QualifiedCoordinates(45.3,-75.3,0,0,0);

        landMarks[2] = new Landmark("CCC", "Description 3", coordinates, null);

        MapsArguments ma = new MapsArguments(landMarks);
        Invoke.invokeApplication(Invoke.APP_TYPE_MAPS, ma);
  }
}

它只标记BBB和CCC，缺少AAA。我认为这是因为AAA缺少坐标。我的问题是如果我只有地址，我怎么能检索一个位置的坐标。

我打赌你必须调用一个可以将地址转换为坐标集的远程服务。 google places API看起来很有希望。
