Estoy tratando de dibujar pintura de dedo con diferentes colores, pero siempre que cambiar el color de la pintura, entonces todos los anteriores camino o dibujo obtener y dibujar con color actualizado quiero dibujar con diferentes colores ¿cómo puedo hacer eso? Por favor, dame algunas soluciones para esto.

 ArrayList<Pair<Path, Paint>> paths = new ArrayList<Pair<Path, Paint>>(); 

 Paint newPaint = new Paint(mPaint); // Clones the mPaint object paths.add(new Pair<Path, Paint>(mPath, newPaint)); 

 for (Pair<Path, Paint> p : paths) { canvas.drawPath(p.first, p.second); }
