I am working on this code, it returns no error but it doesnt display
maps on the emulator... it doesnt seem to be able to find the mapview
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
myMap = (MapView) findViewById(R.id.simpleGM_map); // Get map
from
XML
btnSearch = (Button) findViewById(R.id.simpleGM_btn_search); //
Get
button from xml
adress = (EditText) findViewById(R.id.simpleGM_adress); // Get
address from XML
gc = new Geocoder(this); // create new geocoder instance
btnSearch.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
String addressInput =
adress.getText().toString(); // Get input
text
try {
List<Address> foundAdresses =
gc.getFromLocationName(
addressInput, 5); //
Search addresses
if (foundAdresses.size() == 0) { // if
no address found,
// display an error
Dialog locationError = new
AlertDialog.Builder(
simpleGoogleMaps.this).setIcon(0).setTitle(
"Error").setPositiveButton(R.string.ok, null)
.setMessage(
"Sorry, your address doesn't exist.")
.create();
locationError.show();
} else { // else display address on map
for (int i = 0; i <
foundAdresses.size(); ++i) {
// Save results as
Longitude and Latitude
// @todo: if more than
one result, then show a
// select-list
Address x =
foundAdresses.get(i);
lat = x.getLatitude();
lon = x.getLongitude();
}
navigateToLocation((lat *
1000000), (lon * 1000000),
myMap); //
display the found address
}
} catch (Exception e) {
// @todo: Show error message
}
}
});
}
/**
* Navigates a given MapView to the specified Longitude and Latitude
*
* @param latitude
* @param longitude
* @param mv
*/
public static void navigateToLocation(double latitude, double
longitude,
MapView mv) {
GeoPoint p = new GeoPoint((int) latitude, (int) longitude); //
new
// GeoPoint
mv.displayZoomControls(true); // display Zoom (seems that it
doesn't
// work yet)
MapController mc = mv.getController();
mc.animateTo(p); // move map to the given point
int zoomlevel = mv.getMaxZoomLevel(); // detect maximum zoom
level
mc.setZoom(zoomlevel - 1); // zoom
mv.setSatellite(false); // display only "normal" mapview
}
}
