Android Textview实现时间差小标签

效果图：

具体时间差代码请参考：https://blog.csdn.net/weixin_43477545/article/details/109096335

android中可能会出现当前时间不匹配的问题，只需要设定时区即可解决

		SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        df.setTimeZone(TimeZone.getTimeZone("GMT+08:00"));

获取当前时间与某一时间的时间差

/**
     * 获取输入时间与现在时间差
     * @param log_time 日志时间 格式为2020-6-1 10:00:00
     * @return
     */
    public static String getTime(String log_time){
    
    
        SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        df.setTimeZone(TimeZone.getTimeZone("GMT+08:00"));
        Date time_now = new Date();
        long diff = 0;
        String CountTime = "";
        int year=0,month=0,day=0;
        long hours=0,minutes=0,s=0;
        try {
    
    
            Date time_ago = df.parse(log_time);
            diff = time_now.getTime() - time_ago.getTime();
            Calendar currentTimes =dataToCalendar(time_now);//当前系统时间转Calendar类型
            Calendar  pastTimes =dataToCalendar(time_ago);//查询的数据时间转Calendar类型
            year = currentTimes.get(Calendar.YEAR) - pastTimes.get(Calendar.YEAR);//获取年
            month = currentTimes.get(Calendar.MONTH) - pastTimes.get(Calendar.MONTH);
            day = currentTimes.get(Calendar.DAY_OF_MONTH) - pastTimes.get(Calendar.DAY_OF_MONTH);
            if (month < 0) {
    
    
                month = (month + 12) % 12;//获取月
                year--;
            }
            if (day < 0) {
    
    
                month -= 1;
                currentTimes.add(Calendar.MONTH, -1);
                day = day + currentTimes.getActualMaximum(Calendar.DAY_OF_MONTH);//获取日
            }
            long days = diff / (1000 * 60 * 60 * 24);
            hours = (diff-days*(1000 * 60 * 60 * 24))/(1000* 60 * 60); //获取时
            minutes = (diff-days*(1000 * 60 * 60 * 24)-hours*(1000* 60 * 60))/(1000* 60);  //获取分钟
            s=(diff/1000-days*24*60*60-hours*60*60-minutes*60);//获取秒
            CountTime=""+year+"年"+month+"月"+day+"天"+hours+"小时"+minutes+"分"+s+"秒";
        } catch (ParseException e) {
    
    
            e.printStackTrace();
        }
        return year != 0 ? ""+year+"|"+0 :
                month != 0 ? ""+month+"|"+1 :
                        day != 0 ? ""+day+"|"+2 :
                                hours != 0 ? ""+hours+"|"+3 :
                                        minutes != 0 ? ""+minutes+"|"+4 : ""+s+"|"+5 ;
    }

    public static Calendar dataToCalendar(Date date) {
    
    
        Calendar calendar = Calendar.getInstance();
        calendar.clear();
        calendar.setTime(date);
        return calendar;
    }

此处添加在textview需要的地方，用于变换颜色和内容

String time_group = getTime("2020-10-1 10:30:27" );
int[] time_array = handle_time(time_group);
GradientDrawable gd = (GradientDrawable) holder.tv_log_tag.getBackground();
        gd.setColor(view.getResources().getColor(getColor(time_array[1])));
        textview.setText(parse_time(time_array));

/*--------------------------------以下用于设置日志小标签2min前--------------------------------*/
    private int[] handle_time(String input_time){
    
    
        StringTokenizer fenxi = new StringTokenizer(input_time,"|");
        int[] result = new int[2];
        int i = 0;
        while (fenxi.hasMoreTokens()){
    
    
            result[i] = Integer.parseInt(fenxi.nextToken());
            i++;
        }
        return result;
    }
    private String parse_time(int[] input_array){
    
    
        String[] time_list = {
    
    "年","月","天","小时","分钟","秒"};
        if (input_array[1] == 5)
            return "刚刚";
        else
            return ""+input_array[0]+time_list[input_array[1]]+"前";
    }
    private int getColor(int time_index){
    
    
        int[] color = {
    
    R.color.darkblue,R.color.red,R.color.search_opaque,R.color.orchid,R.color.medium_spring_green,R.color.medium_purple};
        if (time_index>=0 && time_index<=5)
            return color[time_index];
        return color[0];
    }

最后，layout中的textview的背景用drawable目录下的xml表示

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- 设置圆角-->
    <corners android:radius="8dp" />
    <solid android:color="@color/blue"/>
</shape>

注意
textview用的背景xml不要让其他控件使用，因为会影响其他控件背景的正常显示。
