How to convert date and time like timeline in android?

I am learning format date and time in android, I want to try to convert the date and time as the timeline ... ? example:

String current_date = "2013-10-07 20:57:20";

String val_date1 = "2013-10-07 20:57:20";
String val_date2 = "2013-10-07 19:57:20";
String val_date3 = "2013-10-07 17:57:20";
String val_date4 = "2013-09-07 20:57:20";

above date and adjusted CURRENT_DATE converted and the results such as these:

String val_date1_after_formated = "just now";
String val_date2_after_formated = "1h";
String val_date3_after_formated = "3h";
String val_date4_after_formated = "1d";

how to convert date with the program? I hope anyone can help me. Sorry if my English is not good ...

Here a function that should do the job

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
int[] steps = {1,60,3600,3600*24};
String[] names = {"seconds","minutes","hours","days"};

//...

public String formatDelay(String date){
    try {
        Date d = sdf.parse(date);
        Long stamp = d.getTime()/1000;
        Long now = System.currentTimeMillis()/1000;         
        Long dif = now - stamp;

        if(stamp > now) return "";

        for(int i=0;i<steps.length;i++){
            if(dif<steps[i]){
                String output = Long.toString(dif/steps[i-1])+" "+names[i-1];
                return output;
            }
        }       

        return Long.toString(dif/steps[3])+" "+names[3];


    } catch (Exception e){
        e.printStackTrace();
        return "";
    }

Not sure if this is what your looking for but to get the current time use this. Returns in milliseconds. 

System.currentTimeMillis() / 1000L;

To format it to a time date-time use this code. 

long loadDate = System.currentTimeMillis() / 1000L;
String dateString = new SimpleDateFormat("MM/dd/yyyy").format(new Date(loadDate));

formatDuration might be good for this:

public String getDuration(long time) {
    StringBuilder sb = new StringBuilder();
    android.support.v4.util.TimeUtils.formatDuration(System.currentTimeMillis() - date, sb);
    return sb.toString();
}

Now to get the long time you need to parse the input dates (maybe using SimpleDateFormat).

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss", Locale.US);
long date = sdf.parse("2013-10-07 20:57:20").getTime();
String duration = getDuration(date);
