Use method path.quadTo() or path.rQuadTo() can meet your requirement, for example: Assume the radius is what you want defined in your View, the code snippet below in method onDraw() can work for you

...
    if (corner.top()) {
            path.moveTo(0, height);
//            path.lineTo(width / 2, 0);
            path.lineTo(width / 2 - radius, 0 + radius);
            path.quadTo(width / 2, 0, width / 2 + radius, 0 + radius);
            path.lineTo(width, height);
        } else {
            path.moveTo(0, 0);
//            path.lineTo(width / 2, height);
            path.lineTo(width / 2 -radius, height - radius);
            path.quadTo(width /2, height, width/2 +radius, height - radius);
            path.lineTo(width, 0);
        }

For more flexible, you can define attribute radius in attrs.xml file, so that you can define the radius you want in your layout file
