Problem: When I pick the time, say 06:00, it sets the time as 18:00, when I pick the time 18:00 it sets the time as 06:00. I can't seem to figure out why.
................
LOGIC
Gets current date instance.
OnClickListener is set to a ButtonImage.
OnClick calls showTimeDialog with 2 arguments (a TextView, the current date instance).
TimePicker Dialog shows with at a set time of 09:00.
TimeSet sets the time of a Calendar activeTime and updates a TextView

ADDITIONAL NEW INFO
Ok, so strange thing happened, now my code seems to work, BUT last time I checked it was before 24:00 and it was acting as described. It works now and the time is 00:20 here in the UK. I dont know if this has anything to do with it but I will update this post if anything changes.
ADDITIONAL NEW INFO 2
My code seems to work between 00:00 - 12:00 but from 12:00 - 24:00 it doesn't. I'm stumped..
.............
Here is my code:
/////// SETUP TIME
// capture our View elements for the start time function
startTimeDisplay = (TextView) findViewById(R.id.editText2);
endTimeDisplay = (TextView) findViewById(R.id.editText3);
startPickTime = (ImageButton) findViewById(R.id.imageButtonStartTime);
endPickTime = (ImageButton) findViewById(R.id.imageButtonEndTime);
// Use the current time as the default values for the time picker
startTime = Calendar.getInstance();
endTime = Calendar.getInstance();
startTime.get(Calendar.DATE);
endTime.get(Calendar.DATE);
// add a click listener to the button
startPickTime.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
showTimeDialog(startTimeDisplay, startTime);
}
});
/* add a click listener to the button */
endPickTime.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
showTimeDialog(endTimeDisplay, endTime);
}
});
}
@Override
protected Dialog onCreateDialog(int id) {
getTime(activeTime);
int hr = activeTime.get(Calendar.HOUR_OF_DAY);
int mn = activeTime.get(Calendar.MINUTE);
Log.d(TAG, "first hr..." +hr);
Log.d(TAG, "first mn..." +mn);
switch (id) {
case DATE_DIALOG_ID:
return new DatePickerDialog(this, dateSetListener, activeDate.get(Calendar.YEAR), activeDate.get(Calendar.MONTH), activeDate.get(Calendar.DAY_OF_MONTH));
case TIME_DIALOG_ID:
return new TimePickerDialog(this, timeSetListener, THE_HOUR, THE_MINUTE, true);
}
return null;
}
@Override
protected void onPrepareDialog(int id, Dialog dialog) {
super.onPrepareDialog(id, dialog);
getTime(activeTime);
int hr = activeTime.get(Calendar.HOUR_OF_DAY);
int mn = activeTime.get(Calendar.MINUTE);
Log.d(TAG, "second hr..." +hr);
Log.d(TAG, "second mn..." +mn);
switch (id) {
case DATE_DIALOG_ID:
((DatePickerDialog) dialog).updateDate(activeDate.get(Calendar.YEAR), activeDate.get(Calendar.MONTH), activeDate.get(Calendar.DAY_OF_MONTH));
break;
case TIME_DIALOG_ID:
((TimePickerDialog) dialog).updateTime(THE_HOUR, THE_MINUTE);
break;
}
}
public void showTimeDialog(TextView timeDisplay, Calendar date) {
activeTimeDisplay = timeDisplay;
activeTime = date;
showDialog(TIME_DIALOG_ID);
}
private OnTimeSetListener timeSetListener = new OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker view, int hour, int minute) {
activeTime.set(Calendar.HOUR, hour);
activeTime.set(Calendar.MINUTE, minute);
updateTimeDisplay(activeTimeDisplay, activeTime);
unregisterTimeDisplay();
}
};
private void updateTimeDisplay(TextView timeDisplay, Calendar date) {
//convert Calendar to Unix Time
long activeTimeUnixTime = (long) (date.getTimeInMillis());
//convert Unix Time to Date
java.util.Date startTimeDate = new java.util.Date(activeTimeUnixTime);
//convert Date to SimpleDateFormat and convert to String
SimpleDateFormat formatter2;
formatter2 = new SimpleDateFormat("kk:mm", Locale.UK);
String stringTime = formatter2.format(startTimeDate);
timeDisplay.setText(stringTime);
}
private void unregisterTimeDisplay() {
activeTimeDisplay = null;
activeTime = null;
}
SOLUTION:
My onTimeSetListener onTimeSet() method was using HOUR instead of HOUR_OF_DAY.
Okay so I was stuck on this for ages but finally figured it out. But because Im quite new to Android and Calendar the difference alluded me.
Calendar.HOUR is 5 for 17:00 because it's the 5th hour in the PM. Calendar.HOUR_OF_DAY returns 17 for 17:00. So here is the correct code:
private OnTimeSetListener timeSetListener = new OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
activeTime.set(Calendar.HOUR_OF_DAY, hourOfDay);
activeTime.set(Calendar.MINUTE, minute);
updateTimeDisplay(activeTimeDisplay, activeTime);
unregisterTimeDisplay();
}
};
