How get Date and Time from Timestamp to different TextView

I have timestamp in DataBase like this: 1472373943.
In my Adapter I would like set Date & Time to different TextView.
For Example:
How to separate the date and time? Thanks.

First, what is your input? In your question, it looks like 1472373943, So I don't know which is time, and date position in that string. For simple, let assume that you have a sample date and time as follows:
String date = "12/8/2012";
String time = "11:25 am";
So, to convert it. The simple way is
import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
public class DateTest {
public static void main(String[] args) {
String date = "12/8/2012";
String time = "11:25 am";
DateFormat df = new SimpleDateFormat("MM/dd/yyyy hh:mm a");
try {
Date dt = df.parse(date + " " + time);
Calendar ca = Calendar.getInstance();
ca.setTime(dt);
System.out.println(ca.getTimeInMillis());
} catch (ParseException e) {
e.printStackTrace();
}
}
}

You can do that by using two different SimpleDateFormatters on the same Date object, one for the date and the other for the hours. "YYYY/MM/DD" and the other is "HH:mm a", just for an example.

Android date parsing (Extracting month and year )

I want my app to parse the date in format "dd-MMM-yyyy". The date has been successfully parsed when I try to get month and get year it is giving other result. I inpued 06-sep-2014 as date. But when I try to extract month and year from the parsed date it is showing 8 for month instead of 9 and 114 for year instead of 2014.
logcat output
6
8
114
Here's my code
String date1 = "06 sep 2014";
SimpleDateFormat format1 = new SimpleDateFormat("dd MMM yyyy");
SimpleDateFormat format2 = new SimpleDateFormat("d MMM yyyy");
Date date;
try {
if (date1.length() == 11) {
date = format1.parse(date1);
} else {
date = format2.parse(date1);
}
int day=date.getDate();
int mon1=date.getMonth();
int year1=date.getYear();
System.out.println("date is:"+ date);
System.out.println(day);
System.out.println(mon1);
System.out.println(year1);
} catch (ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

import java.text.DateFormat;
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Calendar;
public final class DateParseDemo {
public static void main(String[] args){
final DateFormat df = new SimpleDateFormat("dd MMM yyyy");
final Calendar c = Calendar.getInstance();
try {
c.setTime(df.parse("06 sep 2014"));
System.out.println("Year = " + c.get(Calendar.YEAR));
System.out.println("Month = " + (c.get(Calendar.MONTH)));
System.out.println("Day = " + c.get(Calendar.DAY_OF_MONTH));
}
catch (ParseException e) {
e.printStackTrace();
}
}
}
Output:
Year = 2014
Month = 8
Day = 6
And as for the month field, this is 0-based. This means that January = 0 and December = 11. As stated by the javadoc,
Field number for get and set indicating the month. This is a calendar-specific value. The first month of the year in the Gregorian and Julian calendars is JANUARY which is 0; the last depends on the number of months in a year.

Because date.getyear Returns a value that is the result of subtracting 1900 from the year that contains or begins with the instant in time represented by this Date object, as interpreted in the local time zone.
Maybe, You can use for example;
int year1=date.getYear();
System.out.println(year1+1900);

Using the Date class, it gives you the year starting from 1900. A better way to get what you want is using the Calendar class. See http://developer.android.com/reference/java/util/Date.html#getYear()

Have TextView show day of week as letters not integer

I have a textview which shows the day of the week as an integer (0-7). I would prefer if it could convert that to a string, which could then be shown in a TextView. My code is below. Also, how can I make it so the TextViews update the time, date, etc. (it only shows the time the app is opened)? Thanks in advance.
MainActivity.java:
package press.linx.calendar;
import java.sql.Date;
import java.text.SimpleDateFormat;
import android.os.Bundle;
import android.app.Activity;
import android.text.format.Time;
import android.view.Menu;
import android.widget.TextView;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
TextView day = (TextView)findViewById(R.id.day);
TextView month = (TextView)findViewById(R.id.month);
TextView year = (TextView)findViewById(R.id.year);
TextView time = (TextView)findViewById(R.id.time);
Time today = new Time(Time.getCurrentTimezone());
today.setToNow();
day.setText("" + today.monthDay); // Day of the month (0-31)
month.setText("" + today.month); // Month (0-11)
year.setText("" + today.year); // Year
time.setText("" + today.format("%k:%M")); // Current time
}
}
UPDATE: I got it using this piece of code:
final Calendar calendar = Calendar.getInstance();
SimpleDateFormat formatter = new SimpleDateFormat("MMM"); // 3-letter month name & 2-char day of month
TextView datetxt = (TextView) findViewById(R.id.nameofyourtextview);
datetxt.setText(formatter.format(calendar.getTime()));

To format your Time:
Time time = new Time();
time.format("%A");
It returns name of day in week (Sunday, Friday..) - see description of format string (It's a PHP man page, but the symbols are same and it's well-aranged)
In order to make textViews updated every second you have to use Timer and TimerTask.
Define UpdateTimeTask:
class UpdateTimeTask extends TimerTask {
public void run() {
// Update time, must be called using runOnUiThread
}
}
and then set timer:
Timer timer = new Timer();
TimerTask updateTime = new UpdateTimeTask();
timer.scheduleAtFixedRate(updateTime, 0, 1000);

I assume you are looking for the date to be displayed in the below format.
You can use the below
Date now = new Date();
SimpleDateFormat dateFormatter = new SimpleDateFormat("EEEE, MMMM d, yyyy");
System.out.println("Format : " + dateFormatter.format(now));
Output
Format : Thursday, April 25, 2013
Few helpful links
http://www.ntu.edu.sg/home/ehchua/programming/java/DateTimeCalendar.html
http://www.roseindia.net/tutorial/java/core/convertDateToWords.html

To get the current day of the week (i.e. Monday, Tuesday, Wednesday, etc.) try:
DateFormat fmt = new SimpleDateFormat( "EEEE" );
fmt.format( new java.util.Date() );

Try this
month.setText(getMonth(today.month));
day.setText(getWeek(today.monthDay));
method to get month based on month number
public String getMonth(int month) {
return new DateFormatSymbols().getMonths()[month];
}
method to get week based on week number
public String getWeek(int weekno) {
return new DateFormatSymbols().getWeekdays()[weekno];
}

Do you mean display as Mon, Tue, Wed,.... ?
Use this format.
SimpleDateFormat curFormatDate = new SimpleDateFormat("EEE");

Android Date To Milles (ISO 8601)

am working on countdown widget .The problem is explained below
'2012-07-04T15:00:00Z' - > '1341414000000'
'1341414000000' - > indicate 2012 july 4th 20:30
why this happend? . Am using joda
final String format = "yyyy-MM-dd'T'HH:mm:ssZ";
DateTimeFormatter formatter = DateTimeFormat.forPattern(format);
DateTime endTime = formatter.parseDateTime(strDate);
long diff=endTime.getMillis();

String time="2012-07-04T15:00:00Z";
DateFormat df = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss'Z'", Locale.US);
df.setTimeZone(TimeZone.getTimeZone("UTC"));
// time.replace("Z","");
try {
Date date=df.parse(time);
long diff=date.getTime()-System.currentTimeMillis();
System.out.println("Date "+diff);
} catch (ParseException e) {
e.printStackTrace();
}

This seems like an old question, but I'll answer it anyway, since other people may find this.
In Joda there is a class for ISO 8601 formats, so instead of specifying the format manually you could use that class, as follows:
import org.joda.time.format.DateTimeFormatter;
import org.joda.time.format.ISODateTimeFormat;
import org.joda.time.DateTime;
String strDate = "2012-07-04T15:00:00Z";
DateTimeFormatter formatter = ISODateTimeFormat.dateTimeNoMillis();
DateTime endTime = formatter.parseDateTime(strDate);
long diff=endTime.getMillis();
On the other hand, the problem that you seem to be having is related to the time zone. When you convert back from millis to date string, it gets converted using the local time zone. If you want to get the date as UTC, you should do the following:
import org.joda.time.DateTimeZone;
import org.joda.time.DateTime;
DateTime dt = new DateTime(1341414000000).withZone(DateTimeZone.UTC);
It will return 2012-07-04T15:00:00.000Z as expected. If you want to format it without the milliseconds, you can use the same formatter as before:
import org.joda.time.DateTimeZone;
import org.joda.time.format.DateTimeFormatter;
import org.joda.time.format.ISODateTimeFormat;
import org.joda.time.DateTime;
DateTimeFormatter formatter = ISODateTimeFormat.dateTimeNoMillis();
DateTime dt = new DateTime(1341414000000).withZone(DateTimeZone.UTC);
formatter.print(dt)
And it will return 2012-07-04T15:00:00Z.

Android - get date time from SMS timestamp in miliseconds

is it possible to convert Sms table date value e.g. 1293457709636 (miliseconds) to meaningful Date time value.

just do
long ms = 1293457709636; // or whatever you have read from sms
Date dateFromSms = new Date(ms);

You can convert Sms table date in to meaningful Date time like this.
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Calendar;
DateFormat formatter = new SimpleDateFormat("dd/MM/yyyy hh:mm:ss.SSS");
Calendar calendar = Calendar.getInstance();
long now = 1293457709636L;
calendar.setTimeInMillis(now);
Log.i("time", "time"+formatter.format(calendar.getTime()));
