Converting Timestamp as String to Date in android

Question

I am getting Timestamp value as 1291204449 from server so I extracted the value by implementing handler.

Now I want to convert timestamp value to date.(But the problem is in my activity I stored this value in a string variable because handler returning in string format).

Just use the Time class. Try something similar to this.

Time time = new Time();
time.set(Long.valueOf(yourTimeString));

If you really need a Date object just try this.

Date date = new Date(Long.parse(yourTimeString));

I have a function for converting timestamps in String Format:

public static String create_datestring(String timestring){
    final Calendar cal = Calendar.getInstance();
    cal.setTimeInMillis(Long.parseLong(timestring));
    timestring = add_string(String.valueOf(cal.get(Calendar.DAY_OF_MONTH)),"0",2,0) + "." +  add_string(String.valueOf(cal.get(Calendar.MONTH)+1),"0",2,0) + "." + String.valueOf(cal.get(Calendar.YEAR)) + " " + add_string(String.valueOf(cal.get(Calendar.HOUR_OF_DAY)),"0",2,0) + ":" + add_string(String.valueOf(cal.get(Calendar.MINUTE)),"0",2,0);
    return timestring;
}

Watch out when using the Calender class as it is slower than the Time class. Also concatenating a string that way is not very efficient. Try to use a StringBuilder instead.

@2red13 what is the add_string function? I agree with @Octavian Damiean, maybe a StringBuilder would be more efficient?
