方式2? 可动态修改颜色?

tvContent.setText(getItem(position).getContent());
            GradientDrawable drawable = new GradientDrawable();
            drawable.setShape(GradientDrawable.OVAL);
            String color = "#db5860";
            if (position == 0) {
                color = "#c6f47f";
            } else if (position == 1) {
                color = "#02a4eb";
            } else if (position == 2) {
                color = "#7ecff3";
            } else if (position == 3) {
                color = "#6eb203";
            } else if (position == 4) {
                color = "#bbbb00";
            } else if (position == 5) {
                color = "#f4bc73";
            } else if (position == 6) {
                color = "#e77d8a";
            } else if (position == 7) {
                color = "#be7dfa";
            } else if (position == 8) {
                color = "#7d7dfa";
            }
            drawable.setColor(Color.parseColor(color));//背景颜色
            drawable.setStroke(dpToPx(11), ContextCompat.getColor(getContext(), R.color.white));
            drawable.setSize(dpToPx(19), dpToPx(19));
            tvContent.setBackground(drawable);
