ISSUE:
I have a TimePicker which I'd like to use to save the value of the long/string "minutes" which represents the total number of minutes between the current time and the time selected by the timepicker.
For example: If it is currently 7:30 and the user selects 8:30 it will save 60 minutes as the value of minutes.
I've managed to implement the following source code (shown below) however I'm getting a few errors stating:
"The local variable tp may not have been initialized"
Using the method suggested in the comments below - although I'm following the instructions precisely.

Use java.util.Calendar to get current values and subtract.

cal.set(Calendar.HOUR_OF_DAY, tp.getCurrentHour());
cal.set(Calendar.MINUTE, tp.getCurrentMinute());
long minutes = (cal.getTimeInMillis() -

Edit: Try this Java console application. A proof that it works.
import java.util.Calendar;
public class Main {
public static void main(String[] args) {
Calendar cal = Calendar.getInstance();
cal.set(Calendar.HOUR_OF_DAY, 20);
cal.set(Calendar.MINUTE, 58);
long minutes = (cal.getTimeInMillis() - Calendar.getInstance().getTimeInMillis()) / 1000 / 60;
System.out.println(minutes);
}
}
Returns 4 at 20:54 of my local time.

I am creating an app which monitors temperature live from my SQL server. I was also creating a linegraph using MPAndroidCharts by Phil Jay and came across an issue.
I used the X-axis as a label for time(HH:mm:ss) however the time seems to update all the labels instead of only the last one. I have tried many different methods but none of them work. So I thought I would ask you guys for help. Thank You!

Add following line in your code:

mChart.notifyDataSetChanged(); // add this line
mChart.invalidate();
when i select 12:00 or i Select 0:00 it showing me only AM not PM tried a lot but not getting the required output and I search same question in stack overflow but not getting the output..

}
}
now in Main.java
//

// Initialize a new time picker dialog fragment
DialogFragment dFragment1 = new TImePicker();
// Show the time picker dialog fragment

}
});
I have written this line of code of code:
dateSelected = new GregorianCalendar(tempYear, tempMonth, tempDate,tempHour,tempMinute).getTime();
I got these value from datepicker and timepicker dialogs in android. I am able to get correct values in these integer variables but when I convert them to Date object it will always be 31 dec. I am not able to fix the problem.
I have also tried this approach as well:
Calendar calendar = Calendar.getInstance();
calendar.set(tempYear, tempMonth, tempDate, tempHour, tempMinute);
dateSelected = calendar.getTime();
Whenever Second line is commented out it is working fine. I am perfectly getting current date and time. But when it is uncommented the problem returns.
In case anyone needs my full code:

setResult(Activity.RESULT_OK, resultIntent);
Log.i("Date: ", dateSelected.toString() );
finish();
}
});
}
}
When the code works all variables equal to 0 because a user doesn't pick a date and a time at the moment.
Calendar calendar = Calendar.getInstance();
calendar.set(tempYear, tempMonth, tempDate, tempHour, tempMinute);
dateSelected = calendar.getTime();
Move the code in addEntry's onClickListener implementation and it will work 👍
My app getting crash when I try to set the time more than the current time.
Please solve my problem.
The current time is working fine but the app is crashing when I select time more than current time.
Thanks

Set the time in calendar in showTime() method as follows:
public void showTime() {
if(flag == true) {
Calendar calender = Calendar.getInstance();
myTimePicker = new TimePickerDialog(this, new OnTimeSetListener() {
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
Calendar newTime = Calendar.getInstance();
//newTime.set(hourOfDay, minute); // remove this line
//Add these two line
newTime.set(Calendar.HOUR_OF_DAY, hourOfDay);
newTime.set(Calendar.MINUTE, minute);
GotTime = GotDate + " At " + String.valueOf(hourOfDay) + " :" + String.valueOf(minute + 1);
time.setText(GotTime);
}
}, calender.get((Calendar.HOUR_OF_DAY)), calender.get(Calendar.MINUTE), true);
}
}
EDIT:
To get HourOdDay in am/pm you can do something like this:
String format = "hh:mm a"; // your own format
SimpleDateFormat sdf = new SimpleDateFormat(format, Locale.US);
String formated_time = sdf.format(newTime.getTime());
//formated_time would show you time like "hh:mm am/pm".

Anyone please help me from this error, i really want to say thank you to all of u who can resolve this code, Thanks :D
You haven't initialized the txtDate EtidText.
txtDate = (EditText) findViewById(R.id.txtDate);// or what ever you add the id for txtDate
Then you will be fine.
