                        tvChose.setText(years + "-" + (monthOfYear + 1) + "-" + dayOfMonth);
                        Calendar mycalendar = Calendar.getInstance();//获取现在时间
                        String nowyear = String.valueOf(mycalendar.get(Calendar.YEAR));//获取年份
                        // 用文本框输入年龄
                        int age = Integer.parseInt(nowyear);
                        int birth = age - years;
                        tvOld.setText(birth + "岁");
                        getAstro(monthOfYear + 1, dayOfMonth);
//                        String monthStr = monthOfYear+1>=10?monthOfYear+1+"":"0"+(monthOfYear+1);
                        //获得更改时间后的数据
//                        getlist(years + "-" + monthStr + "-" + dayOfMonth);
                    }
                }, year, month, day).show();
    }
    private String getAstro(int month, int day) {
        String[] astro = new String[]{"摩羯座", "水瓶座", "双鱼座", "白羊座", "金牛座",
                "双子座", "巨蟹座", "狮子座", "处女座", "天秤座", "天蝎座", "射手座", "摩羯座"};
        int[] arr = new int[]{20, 19, 21, 21, 21, 22, 23, 23, 23, 23, 22, 22};// 两个星座分割日
        int index = month;
        // 所查询日期在分割日之前，索引-1，否则不变
        if (day < arr[month - 1]) {
            index = index - 1;
        }
        tvConstellation.setText(astro[index]);
        // 返回索引指向的星座string
        return astro[index];
    }

点击选择日期，选择完毕就会有回显
