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<Overlay> 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;
}
}
