Convert time value to format “hh:mm Am/Pm” using Android

Question

I am getting date value from database like "2013-02-27 06:06:30" using StringTokenizer I will get time separately like below

String startTime = "2013-02-27 06:06:30";

StringTokenizer token = new StringTokenizer(startTime);
String date1 = token.nextToken();  
String time1 = token.nextToken(); 

and in time1 I am getting the result 06:06:30,

Can I re-store it in another variable of type String as follows?

String displayValue = "06:06 AM";

And if time1 variable has the value of

String time = 16:00:00;

then it should be converted to:

String displayValue = "04:00 PM";

Solution 1

I got answer just doing like this.

startTime = "2013-02-27 21:06:30";
StringTokenizer tk = new StringTokenizer(startTime);
String date = tk.nextToken();  
String time = tk.nextToken();

SimpleDateFormat sdf = new SimpleDateFormat("hh:mm:ss");
SimpleDateFormat sdfs = new SimpleDateFormat("hh:mm a");
Date dt;
try {    
    dt = sdf.parse(time);
    System.out.println("Time Display: " + sdfs.format(dt)); // <-- I got result here
} catch (ParseException e) {
    e.printStackTrace();
}

Solution 2

Try this..

Date dt = new Date(date1);
SimpleDateFormat sdf = new SimpleDateFormat("hh:mm aa");
String time1 = sdf.format(dt);

Solution 3

First you don't need to use StringTokenizer to get the string time. Just pass your startTime like this:

// Get date from string
SimpleDateFormat dateFormatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
Date date = dateFormatter.parse(startTime);

// Get time from date
SimpleDateFormat timeFormatter = new SimpleDateFormat("h:mm a");
String displayValue = timeFormatter.format(date);

// Done!

Solution 4

Try this

 String time = "22:35";

try {
     SimpleDateFormat sdf = new SimpleDateFormat("H:mm");
     Date dateObj = sdf.parse(time);
    System.out.println(dateObj);
    System.out.println(new SimpleDateFormat("K:mm").format(dateObj));
} catch (final ParseException e) {
    e.printStackTrace();
}

Solution 5

Date dt = new Date(date1);
SimpleDateFormat sdf = new SimpleDateFormat("hh:mm aa");
String time1 = sdf.format(dt);

output 2.00 a.m.

 Date dt = new Date(date1);
 SimpleDateFormat sdf = new SimpleDateFormat("hh:mm a",Locale.US);
 String time1 = sdf.format(dt);

output 2.00 AM

This answer shows wrong time if your time is xxxx-xx-xx 12:30:00 it shows 12:30 AM instead 12:30 PM

@BhavikMehta Yes, I am facing the same issue.

Thank you. so much for help

Should be SimpleDateFormat sdf = new SimpleDateFormat("hh:mm a",Locale.US);

I also had the same issue as Bhavik Metha. See my answer for the sollution

It seems to repeat what is in the accepted answer (which BTW isn’t fully correct)? Also in 2019 consider not using SimpleDateFormat. That class is notoriously troublesome and long outdated. Instead you may add ThreeTenABP to your Android project in order to use java.time, the modern Java date and time API. It is so much nicer to work with.

[Ole V.V.]

While the formatting is correct, your parsing isn’t. I tried with startTime = "2013-02-27 12:06:30"; and expected 12:06 PM. But I got Time Display: 12:06 AM.

Excellent solution.Thanks.

@androidlearner you might be using HH:mm:ss aa . Instead use hh:mm:ss aa for 12 hour AM-PM format
