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);
