Re: [android-developers] Find the location in Android Map

[Dhrumil Shah]

I thought you want to to display a mark on a map from the latitude and
longitude a user entered in two text fields. But I don't understand if you
want to display that on a MapActivity in your app or in another app.
- I want to display that  on a MapActivity in my app. Not in another
activity.


One thing that may help is if you try to display a mark on a map foir a
given latitude and longitude instead of from a user's input. Have you been
able to do that successfully?
- Yes, I tried with that also. Firstly, I entered hardcore values in the app
of latitude and longitude. Its working.
But everytime we have to change it for different locations. Thats why I put
EditText and button so user can enter its own latitude and longitude.

Re: [android-developers] Find the location in Android Map

[Dhrumil Shah]

Hey TreKing,

If you dont mind, just refer this code.
You exactly got what is going on here. I am new in Android so I dont know
what is stack trace and log? How to check stack trace?

So here is my code.

public class ShowLocation extends MapActivity {
private EditText lat;
private EditText lng;
 GeoPoint gp=null;
 MapController  mapcontroller;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

Button btn = (Button)findViewById(R.id.btnShow);
lat = (EditText)findViewById(R.id.lat);
lng = (EditText)findViewById(R.id.lng);

MapView mapView = (MapView)findViewById(R.id.myGMap);

mapcontroller = mapView.getController();

//gp = new GeoPoint(lat.intValue(), lng.intValue());
mapView.setSatellite(true);
mapView.setTraffic(true);
mapView.setStreetView(true);
mapView.displayZoomControls(true);
mapView.setBuiltInZoomControls(true);

//mapcontroller.animateTo(gp);
mapcontroller.setZoom(2);
LocationManager locationManager;
String context = Context.LOCATION_SERVICE;
locationManager = (LocationManager)getSystemService(context);

Criteria criteria = new Criteria();
criteria.setAccuracy(Criteria.ACCURACY_FINE);
criteria.setAltitudeRequired(true);
criteria.setBearingRequired(false);
criteria.setCostAllowed(true);
criteria.setPowerRequirement(Criteria.POWER_HIGH);
String provider = locationManager.getBestProvider(criteria, true);

 Location location = locationManager.getLastKnownLocation(provider);

btn.setOnClickListener(new View.OnClickListener() {
 @Override
public void onClick(View v) {
// TODO Auto-generated method stub
String _lat = lat.getText().toString();
String _lng = lng.getText().toString();
Uri uri = Uri.parse("geo:"+_lat+","+_lng);
 startActivity(new Intent(Intent.ACTION_VIEW, uri));
//mapcontroller.animateTo(gp);
mapcontroller.setZoom(2);
}
});
String _lat,_lng;
MapOverlay mylocationoverlay = new MapOverlay();
List list = mapView.getOverlays();
list.add(mylocationoverlay);
}
 protected class MapOverlay extends com.google.android.maps.Overlay{
 public boolean draw(Canvas canvas, MapView myGMap, boolean shadow, long
when){
Paint paint = new Paint();
//mapcontroller.animateTo(gp);
super.draw(canvas, myGMap, shadow);
 Point myScreenCoords = new Point();
//mapview.getProjection().toPixels(gp, myScreenCoords);
//paint.setARGB(255, 255, 255, 255);
Drawable marker = getResources().getDrawable(R.drawable.marker);
Bitmap bitmap = BitmapFactory.decodeResource(getResources(),
R.drawable.marker);
canvas.drawBitmap(bitmap, myScreenCoords.x, myScreenCoords.y, paint);
canvas.drawText("Location is at here..", myScreenCoords.x, myScreenCoords.y,
paint);
return true;
}
}
 @Override
protected boolean isRouteDisplayed() {
// TODO Auto-generated method stub
return false;
}
}

Re: [android-developers] Find the location in Android Map

[Dhrumil Shah]

You can change this at any time.
- Ya, i know that thing, but its not working in my this application.

Or you can animate or snap to the exact location.
- I used this method but it generates and force close error on my emulator.

Why not?
-I dont know why not. I try to debug it but it gives me nothing.

Re: [android-developers] Find the location in Android Map

[Dhrumil Shah]

The problem is that zoom of the map is maximum, every time I have to zoom
out the map to show the exact location. And I am not able to put marker on
that location.

The exact location is the location entered by the user in the edit text i.e.
the latitude and longitude of that location.

If u didnt get my question, I can send u my code then run it and suggest me.

Hey Avigadl,

If I change the values of the each direction like DIRECTION_TOP = 0,
DIRECTION_DOWN = 1, DIRECTION_RIGHT = 2, DIRECTION_LEFT = 3; it is working?

I changed that but unfortunetly its not working.
Any other Solution?
