动态设置TextView的margin

//动态设置setMarginStart
        TextView tvName = helper.getView(R.id.tv_name);
        RecyclerView.LayoutParams lp = (RecyclerView.LayoutParams) tvName.getLayoutParams();
        if (isLeftPop) { //不要左边距
            lp.setMarginStart(0);
        } else {//要左边距
            lp.setMarginStart(Utils.dip2px(getContext(), 5));
        }

   
    public static int dip2px(Context context, float dpValue) {
        float scale = context.getResources().getDisplayMetrics().density;
        return (int) (dpValue * scale + 0.5f);
    }
