如何在Java（Android）中将时间戳转为“一分钟前”式可读字符串

完全可行，以下两种方案都可以实现你需要的效果，直接输出String类型用于TextView展示：

方案一：使用Android系统自带工具类（简单高效） #

Android提供了DateUtils类可以快速生成相对时间字符串，无需自己处理时间差计算，自动适配不同时间区间的文案：

import android.text.format.DateUtils;
import android.widget.TextView;

// 你的时间戳（毫秒级）
long timestamp = 1694603269045L;

// 生成相对时间字符串
CharSequence relativeTime = DateUtils.getRelativeTimeSpanString(
    timestamp,
    System.currentTimeMillis(),
    DateUtils.MINUTE_IN_MILLIS,
    DateUtils.FORMAT_ABBREV_RELATIVE | DateUtils.FORMAT_SHOW_DATE
);

// 转换为String后设置到TextView
String timeString = relativeTime.toString();
textView.setText(timeString);

该方法会自动根据时间差输出类似one minute ago、2 hours ago、3 days ago的格式，无需手动处理单复数和区间判断。

方案二：自定义工具类（高度定制化） #

如果需要更精细控制文案内容（比如调整特殊场景的表述），可以自定义工具类实现：

public class TimeAgoUtils {
    private static final long SECOND_MILLIS = 1000;
    private static final long MINUTE_MILLIS = 60 * SECOND_MILLIS;
    private static final long HOUR_MILLIS = 60 * MINUTE_MILLIS;
    private static final long DAY_MILLIS = 24 * HOUR_MILLIS;
    private static final long WEEK_MILLIS = 7 * DAY_MILLIS;
    private static final long MONTH_MILLIS = 30 * DAY_MILLIS;
    private static final long YEAR_MILLIS = 365 * DAY_MILLIS;

    public static String getTimeAgo(long timestamp) {
        long now = System.currentTimeMillis();
        long diff = now - timestamp;
        
        // 处理未来时间的特殊情况
        if (diff < 0) {
            return "just now";
        }

        if (diff < MINUTE_MILLIS) {
            int seconds = (int) (diff / SECOND_MILLIS);
            return seconds == 1 ? "one second ago" : seconds + " seconds ago";
        } else if (diff < HOUR_MILLIS) {
            int minutes = (int) (diff / MINUTE_MILLIS);
            return minutes == 1 ? "one minute ago" : minutes + " minutes ago";
        } else if (diff < DAY_MILLIS) {
            int hours = (int) (diff / HOUR_MILLIS);
            return hours == 1 ? "one hour ago" : hours + " hours ago";
        } else if (diff < WEEK_MILLIS) {
            int days = (int) (diff / DAY_MILLIS);
            return days == 1 ? "one day ago" : days + " days ago";
        } else if (diff < MONTH_MILLIS) {
            int weeks = (int) (diff / WEEK_MILLIS);
            return weeks == 1 ? "one week ago" : weeks + " weeks ago";
        } else if (diff < YEAR_MILLIS) {
            int months = (int) (diff / MONTH_MILLIS);
            return months == 1 ? "one month ago" : months + " months ago";
        } else {
            int years = (int) (diff / YEAR_MILLIS);
            return years == 1 ? "one year ago" : years + " years ago";
        }
    }
}

使用方式：

long timestamp = 1694603269045L;
String timeAgo = TimeAgoUtils.getTimeAgo(timestamp);
textView.setText(timeAgo);
