GradientDrawable corner radius isn't working

Issue

I'm using GradientDrawable for applying corner radius on a rectangle, this drawable is finally set on a TextView

val drawable = GradientDrawable()
drawable.shape = GradientDrawable.RECTANGLE
drawable.setStroke(3, Color.YELLOW)
drawable.setColor(Color.RED)
drawable.cornerRadius = 10.toFloat()
view.setBackgroundDrawable(drawable)

Do you have any idea of why isn't working and is still a rectangle without corner radius being applied?

I tried calling mutate() before but still not working and also tried the cornerRadii but nothing :(

Solution

Here example for how to create GradientDrawable shape programmatically.

GradientDrawable shape = new GradientDrawable();
shape.setShape(GradientDrawable.RECTANGLE);
shape.setColor(Color.RED);
shape.setStroke(3, Color.YELLOW);

For change the radius for all corners of the gradient.

shape.setCornerRadius(15);

For Change the radius for specific corners of the gradient.

shape.setCornerRadii(new float[] { 8, 8, 8, 8, 0, 0, 0, 0 });

You can use this drawable as a background as below :

view.setBackgroundDrawable(shape);
