enter image description here How can i draw path with translucent (semi-transparent) band on canvas (method onDraw in my custom View)? I draw path line by bezier curve (method path.quadTo), but i want to around the line was illuminated translucent band? I tried several approaches:

  1. Try draw path by paint with semi-transparent color 0x8800ff00.
  2. Try use paint.setShader(new BitmapShader(semi-transparent background image)) and draw path by this paint;

But they did not help. There was no effect of translucency.

Does it work if you first draw the curve using a Paint with a much bigger StrokeWidth and a transparent color (this being the glow), then draw your first curve on top of it?
