Listing 7. The onListItemClick() overridden method

@Override

protected void onListItemClick(ListView list,View view,int position,long

dbidentifier)

{

super.onListItemClick(list,view,position,dbidentifier);

try

{

// this commented out code below will launch the Contacts application

// and "view" the contact Intent myIntent = \

new Intent(android.content.

// Intent.VIEW_ACTION,new ContentURI("content://contacts/people/"

// + dbidentifier)); startSubActivity(myIntent,position);

// let's lookup specifics on this record

ContentURI theContact = \

new ContentURI(android.provider.Contacts.ContactMethods.CONTENT_URI.toURI());

// IMPORTANT

// in order to use this sample application, you need to have at least

// one Contact record on your Android emulator\

// and be sure to have populated the 'Home Address field'

// this "where clause" is for HOME address and for the person record

// selected in the GUI (id, dbidentifier)

Cursor c = managedQuery(theContact,null," type = 1 and person = " +

dbidentifier,null);

if (!c.first())

{

showAlert("MSCC","No Contact Methods Available!","",true);

return;

}

String address = c.getString(c.getColumnIndex("data"));

address = address.replace("\n","");

address = address.replace(",","");

address = address.replace(" ","+");

Intent geoIntent = new Intent("android.intent.action.VIEW",

new ContentURI\

("geo:0,0?q=" + address));

startActivity(geoIntent);

}

catch (Exception ee)

{

Log.i(tag,ee.getMessage());

}

Once the address has been obtained, a few simple string operations are required to

clean up the data to prepare it for a query to Google Maps. The geoIntent is a

new Intent created to perform a geo search, which in the default Android Emulator

image is satisfied by a call to Google Maps.

All of the major elements of the first application still hold true for this application.
