Это идеальное решение, пожалуйста, проверьте ....
В вашей деятельности вам необходимо добавить следующие параметры
geopoint = new GeoPoint((int) (Double.parseDouble(lat) * 1E6), (int)Double.parseDouble(lon) * 1E6));
myMapView.getOverlays().add( new DrawableMapOverlay(this,geopoint,R.drawable.map, name));
затем в классе DrawableMapOverlay
import com.google.android.maps.MapView;
import com.google.android.maps.Overlay;
public class DrawableMapOverlay extends Overlay {
private static final double MAX_TAP_DISTANCE_KM = 3;
// Rough approximation - one degree = 50 nautical miles
private static final double MAX_TAP_DISTANCE_DEGREES = MAX_TAP_DISTANCE_KM * 0.5399568 * 50;
private final GeoPoint geoPoint;
private final Context context;
private final int drawable;
private final String workerName;
/**
* @param context the context in which to display the overlay
* @param geoPoint the geographical point where the overlay is located
* @param drawable the ID of the desired drawable
*/
public DrawableMapOverlay(Context context, GeoPoint geoPoint, int drawable,String workerName) {
this.context = context;
this.geoPoint = geoPoint;
this.drawable = drawable;
this.workerName = workerName;
}
@Override
public boolean draw(Canvas canvas, MapView mapView, boolean shadow, long when) {
super.draw(canvas, mapView, shadow);
// Convert geo coordinates to screen pixels
Point screenPoint = new Point();
mapView.getProjection().toPixels(geoPoint, screenPoint);
Paint paint = new Paint();
// Read the image
Bitmap markerImage = BitmapFactory.decodeResource(context.getResources(), drawable);
paint.setStrokeWidth(1);
paint.setARGB(150, 000, 000, 000);
paint.setStyle(Paint.Style.STROKE);
// Draw it, centered around the given coordinates
canvas.drawBitmap(markerImage,
screenPoint.x - markerImage.getWidth() / 2,
screenPoint.y - markerImage.getHeight() / 2, null);
canvas.drawText(workerName, screenPoint.x- markerImage.getWidth() / 2, screenPoint.y - markerImage.getHeight() / 2 , paint);
return true;
}
@Override
public boolean onTap(GeoPoint p, MapView mapView) {
// Handle tapping on the overlay here
return true;
}
}
В моем проекте все работает нормально.
