黑莓地图事情可以包括位置:
BlackBerry Map
It's not possible in Blackberry Map to show custom icon for POI.
Things you can include in Location on Blackberry Map:
- 的位置* 100,000纬度。南为负。
- 的位置* 100,000经度。西为负。
- 要显示的位置旁边的标签。
- 的说明时,BlackBerry智能手机用户选择结果显示
详细信息。 - 从0缩放级别,以便MAX_ZOOM。
- 地址
- 城市
- 省或州
- 国家
- 邮政code

作为一种替代方法,您可以尝试的 MapField +经理/屏幕漆覆盖。
As an alternative you can try MapField + manager/screen paint override.
自定义扩展MapField:
Custom extension for MapField:
class CustomMapField extends MapField {
Bitmap mIcon;
XYRect mDest;
public void moveTo(Coordinates coordinates) {
super.moveTo(coordinates);
mDest = null;
}
protected void paint(Graphics graphics) {
super.paint(graphics);
if (null != mIcon) {
if (null == mDest) {
XYPoint fieldOut = new XYPoint();
convertWorldToField(getCoordinates(), fieldOut);
int imgW = mIcon.getWidth();
int imgH = mIcon.getHeight();
mDest = new XYRect(fieldOut.x - imgW / 2,
fieldOut.y - imgH, imgW, imgH);
}
graphics.drawBitmap(mDest, mIcon, 0, 0);
}
}
}
使用的示例:
class Scr extends MainScreen {
CustomMapField mMapField;
Coordinates mCoordinates;
public Scr() {
LocationProvider provider = null;
Location location = null;
try {
provider = LocationProvider.getInstance(null);
} catch (LocationException e) {
e.printStackTrace();
}
try {
location = provider.getLocation(-1);
} catch (LocationException e) {
e.printStackTrace();
} catch (InterruptedException e) {
e.printStackTrace();
}
mCoordinates = location.getQualifiedCoordinates();
add(new LabelField("Latitude: "
+ String.valueOf(Coordinates.convert(
mCoordinates.getLatitude(),
Coordinates.DD_MM_SS))));
add(new LabelField("Longitude: "
+ String.valueOf(Coordinates.convert(
mCoordinates.getLongitude(),
Coordinates.DD_MM_SS))));
mMapField = new CustomMapField();
mMapField.mIcon = Bitmap.getBitmapResource("poi_icon.png");
mMapField.moveTo(mCoordinates);
add(mMapField);
}
}

在黑莓
使用MapComponent

如果它是真实的设备,确保GPS可用且已打开。结果
如果是模拟器,然后你开始之前计划使用模拟器菜单 - >模拟 - > GPS位置设置GPS数据结果。
另一种选择是很难code你自己Coordinats并使用它们没有GPS:
If it's real device, be sure GPS is available and turned on.
If it's simulator, then before you start program use simulator menu -> simulate -> GPS Location to set GPS data.
Other option is hardcode your own Coordinats and use them without GPS:
double latitude = 51.507778;
double longitude = -0.128056;
Coordinates mCoordinates = new Coordinates(latitude, longitude, 0);
