Although, you can go for splitting the string using a regex, but here, this is what you need to learn. SimpleDateFormat. This will give you a lot more control especially when you'll use time with it.

  • Java 

SimpleDateFormat format = new SimpleDateFormat("dd/MM/yyyy", Locale.getDefault());
Date yourDate = format.parse("25/05/1995");
Calendar yourCal = new Calendar.getInstance();
yourCal.setTime(yourDate);
Log.d("Tag","Day : "+ yourCal.get(Calendar.DAY_OF_MONTH));
Log.d("Tag","Month: " + yourCal.get(Calendar.MONTH) + 1);
Log.d("Tag","Year: " + yourCal.get(Calendar.YEAR));
  • Kotlin

val format = SimpleDateFormat("dd/MM/yyyy", Locale.getDefault())
val yourDate = format.parse("25/05/1995")
val yourCal: Calendar = Calendar.getInstance()
yourCal.time = yourDate!!
Log.d("Tag", "Day : " + yourCal[Calendar.DAY_OF_MONTH])
Log.d("Tag", "Month: " + yourCal.get(Calendar.MONTH) + 1)
Log.d("Tag", "Year: " + yourCal.get(Calendar.YEAR))

Remember, month starts from 0 for January so you've to +1 in that, And capital 'M' denotes month in java where as small 'm' denotes minutes. There are lots of formats for SimpleDateFormat, you can use any of them.

Just use the appropriate function. String#split()

String dob = editTextDate.getText().split("/")[2]
