So I have been looking into this for a couple of days, and I am pretty
sure the intent of the android API team is to make SearchManager a
platform level tool for searching application level content, like a
application database, which is very cool, and I will probably use, but
not what I want at this moment.
I want to be able search a map just like the Google search apis for
javascript:
// We'll wait to the end to actually initialize the map
// So let's build the search control
searchControl = new google.search.SearchControl();
// Initialize a LocalSearch instance
searcher = new google.search.LocalSearch(); // create the object
//google.search.LocalSearch.ADDRESS_LOOKUP_ENABLED
searcher.setCenterPoint(map); // bind the searcher to the map
// Create a SearcherOptions object to ensure we can see all
results
var options = new google.search.SearcherOptions(); // create the
object
options.setExpandMode
(google.search.SearchControl.EXPAND_MODE_OPEN);
// Add the searcher to the SearchControl
searchControl.addSearcher(searcher , options);
// And second, we need is a search complete callback!
searchControl.setSearchCompleteCallback(searcher , function() {
map.clearOverlays();
var results = searcher.results; // Grab the results array
// We loop through to get the points
for (var i = 0; i < results.length; i++) {
var result = results[i]; // Get the specific result
var markerLatLng = new google.maps.LatLng(parseFloat
(result.lat),
parseFloat
(result.lng));
var marker = new google.maps.Marker(markerLatLng); // Create
the marker
// Bind information for the infoWindow aka the map marker
popup
marker.bindInfoWindow(result.html.cloneNode(true));
result.marker = marker; // bind the marker to the result
map.addOverlay(marker); // add the marker to the map
}
This *was* in previous versions of the API (1.0?) I have seen very old
code like:
// W00t! Search for Pizza.
// Create a MapPoint from the map's coordinates
MapPoint mapPoint = new MapPoint(mMapView.getMapCenter
().getLatitudeE6(),
mMapView.getMapCenter().getLongitudeE6());
// Create a dummy Map for use in Search
Map map = new Map(getDispatcher(), null, 0, 0, 0,
mapPoint,
Zoom.getZoom(mMapView.getZoomLevel()), 0);
// Search for Pizza near the specified coordinates
Search search = new Search("Pizza", map, 0);
// add the request the dispatcher
getDispatcher().addDataRequest(search);
// Wait for the search to complete, Should do this
// in another thread ideally, this is just for
illustration here.
while (!search.isComplete()) {
Log.i(LOG_TAG, ".");
}
// Print the details.
Log.i(LOG_TAG, "Done - " + search.numPlacemarks());
MapPoint point = null;
for (int i = 0; i < search.numPlacemarks(); i++) {
Placemark placemark = search.getPlacemark(i);
point = placemark.getLocation();
Log.i(LOG_TAG, " - i : " + Integer.toString(i));
Log.i(LOG_TAG, "- Bubble : " +
placemark.getBubbleDescriptor());
Log.i(LOG_TAG, "- Detail : " +
placemark.getDetailsDescriptor());
Log.i(LOG_TAG, "- Title : " + placemark.getTitle());
Log.i(LOG_TAG, "- Location : " + placemark.getLocation
().toString());
Log.i(LOG_TAG, "- routable : " +
placemark.routableString());
}
// Animate to the last location.
if (point != null) {
MapController mc = mMapView.getController();
Point point1 = new Point(point.getLatitude(),
point.getLongitude());
mc.animateTo(point1);
mc.zoomTo(12);
Log.i("animateTo", point1.toString());
}
I have been thinking it could be possible by geocoding an address
using the location manager:
//first find the location using geocoding
Geocoder geocoder =
new Geocoder(getApplicationContext(),
Locale.getDefault());
try {
List<Address> addrs =
geocoder.getFromLocation(mMyLocationLat, mMyLocationLon, 1);
} catch (IOException e) {
Log.e(TAG, "geocoding failed");
}
and then pre populating the search with something like "pizza @94611",
but right now when I do search the results go to a browser, I really
want to be able to parse the results myself using an api.
Does anyone know of an example like this or can give me some advice,
the API docs on SearchManager are a little difficult because I think
the intentions are mixed. Is this the right approach? Is it even
possible?
