Question

I am developing an app which is similiar to android facebook app.

I got an created time field from facebook app

  "created_time": "2012-11-28T12:53:40+0000",

So, how can I convert this into date format of android facebook app,like

2hours ago,
yesterday at 5:30pm etc

Answer 1

Try this:

String getCreatedTime = JOConversations.getString("created_time");
long finalTimeStamp = Long.valueOf(getCreatedTime);
SimpleDateFormat dateFormatter = new SimpleDateFormat("yyyy-MM-dd'T'hh:mm:ssZ");

SimpleDateFormat formatter = getDateFormat();
ParsePosition pos = new ParsePosition(0);
long then = formatter.parse(timestamp, pos).getTime();
long now = new Date().getTime();

long seconds = (now - then)/1000;
long minutes = seconds/60;
long hours = minutes/60;
long days = hours/24;

String friendly = null;
long num = 0;
if (days > 0) {
    num = days;
    friendly = days + " day";
} else if (hours > 0) {
    num = hours;
    friendly = hours + " hour";
} else if (minutes > 0) {
    num = minutes;
    friendly = minutes + " minute";
} else {
    num = seconds;
    friendly = seconds + " second";
}
if (num > 1) {
    friendly += "s";
}
String postTimeStamp = friendly.toUpperCase() + " AGO";

And a helper method for this bit here: SimpleDateFormat dateFormatter = new SimpleDateFormat("yyyy-MM-dd'T'hh:mm:ssZ"); is

private static SimpleDateFormat getDateFormat() {
    return new SimpleDateFormat("yyyy-MM-dd'T'hh:mm:ssZ");
}

I derived this code block from the StreamRenderer.java in the Facebook SDK exmples on GitHub here: https://github.com/facebook/facebook-android-sdk/blob/master/examples/stream/src/com/facebook/stream/StreamRenderer.java (Check Line No. 380 onwards)

It does not deal with the scenario yesterday at 5:30pm. But this should get you started.
