关于代码设置bl_stroke_position的问题 about backgroundlibrary

[lsCoding666]

好吧，看了有关代码，实现了

    @Override
    public void onBindHeaderViewHolder(BaseViewHolder holder, int groupPosition) {
        StationCarBean entity = mGroups.get(groupPosition);
//        holder.setText(R.id.tv_expandable_header, entity.getHeader());
        RelativeLayout relativeLayout = holder.get(R.id.rl);
        ImageView ivState = holder.get(R.id.iv_state);
        if (entity.isExpand()) {
            ivState.setRotation(0);
            GradientDrawable gradientDrawable = new GradientDrawable();
            gradientDrawable.setCornerRadii(new float[]{ScreenUtil.dip2px(4), ScreenUtil.dip2px(4), ScreenUtil.dip2px(4), ScreenUtil.dip2px(4), 0, 0, 0, 0});
            Drawable drawable = new DrawableCreator.Builder().setStrokeColor(XUtil.getColor(R.color.comit_common_blue))
                    .setBaseGradientDrawable(gradientDrawable).
                    setStrokeWidth(ScreenUtil.dip2px(1)).build();

            // 创建ShapeDrawable并设置形状和颜色
            drawable = new LayerDrawable(new Drawable[]{drawable});
            ((LayerDrawable) drawable).setLayerInset(0, 0, 0, 0, -ScreenUtil.dip2px(1));
            relativeLayout.setBackground(drawable);
        } else {
            ivState.setRotation(-90);
            Drawable drawable = new DrawableCreator.Builder().setStrokeColor(XUtil.getColor(R.color.comit_gray7))
                    .setCornersRadius(ScreenUtil.dip2px(4)).
                    setStrokeWidth(ScreenUtil.dip2px(1)).build();


            // 创建ShapeDrawable并设置形状和颜色
            drawable = new LayerDrawable(new Drawable[]{drawable});
            ((LayerDrawable) drawable).setLayerInset(0, 0, 0, 0, 0);
            relativeLayout.setBackground(drawable);
        }

        holder.setText(R.id.tvStationName, entity.getCheckName());
        holder.setText(R.id.tvOverLoadNum, entity.getCount() + "次");
    }
