Android ShapeDrawable set Background and Border programmatically

问题

I have a ShapeDrawable:

final ShapeDrawable drawable = new ShapeDrawable(shape);
drawable.getPaint().setStyle(Paint.Style.FILL);
drawable.getPaint().setColor(0xFFffffff);

I want to set border(stroke) color and width for this drawable.

I try setStyle(Paint.Style.FILL_AND_STROKE) but it set background and border with same color

回答1:

Use

drawable.getPaint().setStyle(Paint.Style.STROKE);
drawable.getPaint().setStrokeWidth(2); // in pixel
