Timeago class in android

In this article we create Timeago function for change time.

For example AWeek ago, A Day ago, A Minute ago etc.

For Change your time in above format use below class for change your time to Timeago format.

Create object of TimeAgo class.

TimeAgo timeAgo = new TimeAgo(YOUR CLASS NAME HERE.this);

timeAgo.timeAgo(PASS YOUR STRING DATE HERE, PASS DATE FORMATTER HERE) ;

Below I describe the example with use of TimeAgo class.

public class MainActivity extends Activity {

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        TimeAgo timeago = new TimeAgo(MainActivity.this);

        String time1 = timeago.timeAgo("2014-09-20 00:10", "yyyy-MM-dd HH:mm");

        String time2 = timeago.timeAgo("2014-09-20 11:59", "yyyy-MM-dd HH:mm");

        String time3= timeago.timeAgo("2014-09-28 11:59", "yyyy-MM-dd HH:mm");

        TextView textView1 = (TextView) findViewById(R.id.textView1);

        TextView textView2 = (TextView) findViewById(R.id.textView2);

        TextView textView3 = (TextView) findViewById(R.id.textView3);

        textView1.setText(time1);

        textView2.setText(time2);

        textView3.setText(time3);

    }

}

Output of above example is like below.

First of add below this string to your string.xml file in your android project.

    <string name="time_ago_prefix"></string>

    <string name="time_ago_suffix">ago</string>

    <string name="time_ago_seconds">less than a minute</string>

    <string name="time_ago_minute">about a minute</string>

    <string name="time_ago_minutes">%d minutes</string>

    <string name="time_ago_hour">about an hour</string>

    <string name="time_ago_hours">about %d hours</string>

    <string name="time_ago_day">a day</string>

    <string name="time_ago_days">%d days</string>

    <string name="time_ago_month">about a month</string>

    <string name="time_ago_months">%d months</string>

    <string name="time_ago_year">about a year</string>

    <string name="time_ago_years">%d years</string>

Add this below TimeAgo.java  class in your package of android Project.

public class TimeAgo {

protected Context context;

public TimeAgo(Context context) {

this.context = context;

}

public String timeAgo(String strDate,String format) {

SimpleDateFormat formatter = new SimpleDateFormat(format);

try {

return timeAgo(formatter.parse(strDate));

} catch (ParseException e) {

e.printStackTrace();

}

return "";

}

public String timeAgo(Date date) {

return timeAgo(date.getTime());

}

public String timeAgo(long millis) {

long diff = new Date().getTime() - millis;

Resources r = context.getResources();

String prefix = r.getString(R.string.time_ago_prefix);

String suffix = r.getString(R.string.time_ago_suffix);

double seconds = Math.abs(diff) / 1000;

double minutes = seconds / 60;

double hours = minutes / 60;

double days = hours / 24;

double years = days / 365;

String words;

if (seconds < 45) {

words = r.getString(R.string.time_ago_seconds, Math.round(seconds));

} else if (seconds < 90) {

words = r.getString(R.string.time_ago_minute, 1);

} else if (minutes < 45) {

words = r.getString(R.string.time_ago_minutes, Math.round(minutes));

} else if (minutes < 90) {

words = r.getString(R.string.time_ago_hour, 1);

} else if (hours < 24) {

words = r.getString(R.string.time_ago_hours, Math.round(hours));

} else if (hours < 42) {

words = r.getString(R.string.time_ago_day, 1);

} else if (days < 30) {

words = r.getString(R.string.time_ago_days, Math.round(days));

} else if (days < 45) {

words = r.getString(R.string.time_ago_month, 1);

} else if (days < 365) {

words = r.getString(R.string.time_ago_months, Math.round(days / 30));

} else if (years < 1.5) {

words = r.getString(R.string.time_ago_year, 1);

} else {

words = r.getString(R.string.time_ago_years, Math.round(years));

}

StringBuilder sb = new StringBuilder();

if (prefix != null && prefix.length() > 0) {

sb.append(prefix).append(" ");

}

sb.append(words);

if (suffix != null && suffix.length() > 0) {

sb.append(" ").append(suffix);

}

return sb.toString().trim();

}

}
