Your data pattern seems to be wrong. If your original date string is 2014-05-02T21:00:00+01:00
it should be yyyy-MM-dd'T'HH:mm:ss.Z
without have to trim or replace "T" char
Joda DateTime IllegalArgument exception converting a String to DateTime
Domanda
Im trying to convert a String to a DateTime
object then only saving the Time part back in a String
.
I'm getting the above exception. How can i just exstract the time part eg H:mm from the original?
So the original DateTime is: 2014-05-02T21:00:00+01:00
and i would like just the 21:00
part.
Log.e(TAG, "recordItem[0] = " + recordItem[0]);
recordItem[0] = recordItem[0].replace('[', ' ');
recordItem[0] = recordItem[0].trim();
recordItem[0] = recordItem[0].replace('T', ' ');
DateTimeFormatter dtf = DateTimeFormat.forPattern("yyyy-MM-dd H:mm:ss.SSS");
DateTime dt = dtf.parseDateTime(recordItem[0]);
DateTimeFormatter fmt = DateTimeFormat.forPattern("H:mm");
String formattedStart = fmt.print(dt);
Log.e(TAG, "formattedStart = " + formattedStart);
callStartTime = formattedStart;
.
Console logs:

ISO 8601
Your input string complies with the ISO 8601 standard. Both Joda-Time and java.time frameworks use this standard as their defaults when parsing/generating textual representations of date-time values. So no need to specify a coded parsing pattern or formatter.
Joda-Time
The following code creates a date-time assigned an offset-from-UTC of +01:00
.
DateTime dateTime = DateTime.parse( "2014-05-02T21:00:00+01:00" );
Using a constructor has a different meaning. The following code parses the value with the embedded offset but then adjusts the results into your JVM’s current default time zone.
DateTime dateTime = new DateTime( "2014-05-02T21:00:00+01:00" ) );
To account for Daylight Saving Time (DST) and other anomalies, adjust into your desired/expected time zone rather than just an offset-from-UTC. Use a proper time zone name, in the format of continent/region
such as Africa/Tunis
or Europe/Paris
. Never use the 3-4 letter codes such as EST
or IST
that are neither standardized nor unique.
DateTimeZone zone = DateTimezone.forID( "Europe/Paris" );
DateTime dateTime_Europe_Paris = dateTime.withZone( zone );
From that DateTime object we generate a String representation of its time-of-day value. We need a DateTimeFormatter
to define this String format. Fortunately, Joda-Time already has one pre-defined for us, with just hour and minute values, accessed by calling the static method IsoDateTimeFormat.hourMinute()
.
DateTimeFormatter formatter = ISODateTimeFormat.hourMinute();
String output = formatter.print( dateTime_Europe_Paris );
