我的问题是，我想以编程方式更改可绘制资源半径

找到解决方案

  float[] statusRadii = new float[]{12, 12, 12, 12, 12, 12, 12, 12}; // For Corners
  GradientDrawable approvedStatusBg = new GradientDrawable();
        approvedStatusBg.setShape(GradientDrawable.RECTANGLE);
        approvedStatusBg.setCornerRadii(statusRadii);
        approvedStatusBg.setColor(Color.parseColor("#66BB6A"));

  float[] statusRadii = new float[]{12, 12, 12, 12, 12, 12, 12, 12}; // For Corners
  GradientDrawable approvedStatusBg = new GradientDrawable();
        approvedStatusBg.setShape(GradientDrawable.RECTANGLE);
        approvedStatusBg.setCornerRadii(statusRadii);
        approvedStatusBg.setColor(Color.parseColor("#66BB6A"));
