Draw line on Canvas
//simple line Paint p1 = new Paint(); p1.setAntiAlias(true); p1.setColor(Color.BLACK); p1.setStrokeWidth(10); canvas.drawLine(10, 40, 400, 40, p1); //line with color Paint p2 = new Paint(); p2.setAntiAlias(true); p2.setColor(Color.RED); p2.setStrokeWidth(10); canvas.drawLine(10, 80, 400, 80, p2); //line with round ends Paint p3 = new Paint(); p3.setAntiAlias(true); p3.setColor(Color.BLUE); p3.setStrokeWidth(10); p3.setStrokeCap(Paint.Cap.ROUND); canvas.drawLine(10, 120, 400, 120, p3); //slanted line Paint p4 = new Paint(); p4.setAntiAlias(true); p4.setColor(Color.GREEN); p4.setStrokeWidth(10); canvas.drawLine(10, 160, 400, 200, p4);
