Thank you for your answer. But is there any way to caculate length from point A to point B?

Yes there is a way.

The MapView class has a function toMapPoint(float screenx, float screeny).

You could use this function to determine the real distance between two points, and use it to draw a scalebar yourself.

calculating the length itself:

Point strtPoint = mapview.toMapPoint(screenX1, screenY1);
Point endPoint = mapview.toMapPoint(screenX2, screenY2);
Line line = new Line();
line.setStart(strtPoint);
line.setEnd(endPoint);
double length = line.calculateLength2D();

Regards

Gwen
