How to calculate the time difference between two time fields , with respect to the date changes

Question

I want to calculate the time difference.I have three EditTexts , I want to input the times in the first two edittexts in HH:MM format. And then calculate the time difference

Answer 1

Time Difference is calculated by following code:

long difference = date2.getTime() - date1.getTime(); 
days = (int) (difference / (1000*60*60*24));  
hours = (int) ((difference - (1000*60*60*24*days)) / (1000*60*60)); 
min = (int) (difference - (1000*60*60*24*days) - (1000*60*60*hours)) / (1000*60);

EDIT :

date1 and date2 are Date objects, if you have EditText then you can convert your text in to Date object by using following code,

  DateFormat formatter = new SimpleDateFormat("dd/MM/yyyy"); // Make sure user insert date into edittext in this format.
     Date dateObject;

  try{
    String dob=(tx.getText().toString());
    dateObject = formatter.parse(dob);
    date = new SimpleDateFormat("dd/MM/yyyy").format(dateObject);

    }
