10. Add Mapping Option
*NOTE: In order to test this feature the newest version of the simulator must be installed
10.1. In order to implement Address Locator we need to add address field and getter/setter methods to Student class:
public Student(String firstName, String lastName, String email, String address) {
this.firstName = firstName;
this.lastName = lastName;
this.email = email;
this.email = address; //add address field
}
public String getAddress(){
return address;
}
public void setAddress(String address){
this.address = address;
}10.2. Add EditTextFields to Add, Edit and view option:
viewItem
BasicEditField addressField = new BasicEditField("address: ",student.getAddress(),50,Field.NON_FOCUSABLE);
addressField.setBorder(roundedBorder);
addressField.setBackground(solidBackground);
add(addressField);addItem
EditField inputField4 = new EditField("Student's address: ","");
addDialog.add(inputField4);
// Display the dialog and add a new element to the list
if(addDialog.doModal() == 0) {
addElementToList(new Student(inputField1.getText(),inputField2.getText(),inputField3.getText(), inputField4.getText()));
}editItem
EditField inputField4 = new EditField("Address: ",studentOld.getAddress());
editDialog.add(inputField4);
if(editDialog.doModal() == 0)
{
studentNew.setFirstName(inputField1.getText());
studentNew.setLastName(inputField2.getText());
studentNew.setEmail(inputField3.getText());
studentNew.setAddress(inputField4.getText()); //set Address
editListElement(studentOld, studentNew);
}10.3. Add the Map Option to the manu:
//Show the address on the map
ImageMenuItem mapItem = new ImageMenuItem("Address on Map", 500, 5, MENU_MAP);
_mainScreen.addMenuItem(mapItem);10.4. Implement address locator:
mapItem.setCommand(new Command(new CommandHandler(){
public void execute(ReadOnlyCommandMetadata metadata, Object context)
{
Student student = (Student) _keywordFilterField.getSelectedElement();
if(student != null)
{
try
{
String address = student.getAddress();
showAddress(address);
} catch(LocatorException ex){
Dialog.alert("cannot get location: " + ex.getMessage());
}
catch(Exception ex){
Dialog.alert("map application is not available: "+ ex.getMessage());
}
}
}
}));10.5. Implement showAddress() method. The Locator.geocode()</code?> method must be in another thread:
public void showAddress(String adrs)throws LocatorException{
final String address = adrs;
new Thread(new Runnable(){
public void run(){
try {
Landmark[] landm = Locator.geocode(address, null);
MapsArguments ma = new MapsArguments(landm);
Invoke.invokeApplication(Invoke.APP_TYPE_MAPS, ma);
} catch (Exception ex) {
Dialog.alert("Exception when getting location: " + ex.getMessage());
}
}
}).start();
}10.6. Change the Run Configuration in order to show maps:
and
10.7. Run the application, selected a Student and from the menu select Address on Map:
