hi

how can i draw some continuously lines between some geopoints.

with this code we can but fill the area with the color. i dont want to fill the area:

 Paint paint = AndroidGraphicFactory.INSTANCE.createPaint();
 paint.setColor(android.graphics.Color.parseColor("#772F4198"));
paint.setStrokeWidth(3);
 Polyline polyline = new Polyline(paint, AndroidGraphicFactory.INSTANCE);
 List<LatLong> coordinateList = polyline.getLatLongs();

 //coordinateList.addAll(coordList);
 coordinateList.add(new LatLong(36.43454,52.4154133));
 coordinateList.add(new LatLong(36.440905,52.4203833));
 coordinateList.add(new LatLong(36.4477033,52.42351));
 coordinateList.add(new LatLong(36.4476467,52.4235267));
 mapView.getLayerManager().getLayers().add(polyline);

Don't understand the question. With polyline layer can draw lines on map, based on a series of coordinates. What else do you mean?

sorry for bad question.

i mean draw line between some geopoints what i want to do. but with above code will draw a poligone between my coordinates.

this method will work well:

public int createPolyline(List<LatLong> coordinates, float strokeWidth) {
 Paint paint = AndroidGraphicFactory.INSTANCE.createPaint();
 paint.setStyle(Style.STROKE);
 paint.setColor(android.graphics.Color.parseColor("#772F4198"));
 paint.setStrokeWidth(strokeWidth);

 Polyline pl = new Polyline(paint,AndroidGraphicFactory.INSTANCE);
 pl.getLatLongs().addAll(coordinates);
 mapView.getLayerManager().getLayers().add(pl);
 mapView.getLayerManager().redrawLayers();
 return pl.hashCode();
}

 it seems needed to setStyle parameters.

It's recommended always to check library samples where all these are demonstrated.
e.g. OverlayMapViewer
