Open BlackBerry Maps to display a custom map view

A MapView object represents the view that the BlackBerry® Maps displays. The MapView object contains the latitude and

longitude that the BlackBerry Maps uses as the center of the map and the zoom and rotation values for the map that it displays.

Import the net.rim.blackberry.api.maps.MapView class.

import net.rim.blackberry.api.maps.MapView;

Create an instance of a MapView object.

MapView mapView = new MapView();

Modify the latitude, longitude, and zoom values for the MapView object.

mapView.setLatitude(4331168);

mapView.setLongitude(-8055339);

mapView.setZoom(10);

Invoke invokeApplication() using the APP_TYPE_MAPS constant parameter, and a new

MapsArguments object that uses the MapView object you created.

Invoke.invokeApplication(Invoke.APP_TYPE_MAPS, new MapsArguments

(mapView));

View a sample application that displays a custom map view

From the BlackBerry® Integrated Development Environment, launch the BlackBerryMapsDemo project.

In the BlackBerry Smartphone Simulator, click BlackBerry Maps Demo.

Open the menu and click Invoke Map View.

Open the menu and click View Map.

You can create a BlackBerry® Application that displays a map for the address of a contact in the contact list. The address for the

contact must be a valid address.

Import the javax.microedition.pim.PIM class and the javax.microedition.pim.Contact

interface.

import javax.microedition.pim.PIM;

import javax.microedition.pim.Contact ;

Create a Contact object.

Contact c = null;

In a try block, get the contact list.

try {

ContactList contactList = (ContactList)PIM.getInstance().openPIMList

(PIM.CONTACT_LIST, PIM.READ_WRITE);
