public voidsetCornerRadii(float[] radii)
Specify radii for each of the 4 corners. For each corner, the array contains 2 values, [X_radius, Y_radius]. The corners are ordered top-left, top-right, bottom-right, bottom-left

param
radii the x and y radii of the corners

        if (radii == null) {
            if (getShape() != null) {
                setShape(null);

        } else {
            setShape(new RoundRectShape(radii, null, null));
        }
        invalidateSelf();
public voidsetCornerRadius(float radius)
Specify radius for the corners of the rectangle. If this is > 0, then the drawable is drawn in a round-rectangle, rather than a rectangle.

param
radius the radius for the corners of the rectangle

        float[] radii = null;
        if (radius > 0) {
            radii = new float[8];
            for (int i = 0; i < 8; i++) {
                radii[i] = radius;
            }
        }
        setCornerRadii(radii);
