Android Material Date Picker Date Format

I'm using material date picker in my app to select dates. Below is my code.

MaterialDatePicker.Builder builder = MaterialDatePicker.Builder.datePicker();
    builder.setSelection(Calendar.getInstance().getTimeInMillis());
    builder.setTitleText(getString(R.string.selectDate));
    final MaterialDatePicker materialDatePicker = builder.build();

    btn_pickDate(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            materialDatePicker.show(getSupportFragmentManager(),"DATE_PICKER");
        }
    });
    
    materialDatePicker.addOnPositiveButtonClickListener(new MaterialPickerOnPositiveButtonClickListener() {
        @Override
        public void onPositiveButtonClick(Object selection) {
            startDate.setText(materialDatePicker.getHeaderText());
        }
    });

when I select a date, the date is returned in dd MMM yyyy in device one and MMM dd, yyyy in device two.

I need the date to be returned in same format (Ex: dd MMM yyyy) across all devices. How to achieve this in material date picker.

The addOnPositiveButtonClickListener listener returns the selected date as Long value. In this way you have a long value and not a String.

You can use:

    MaterialDatePicker<Long> materialDatePicker = builder.build();
    
    materialDatePicker.addOnPositiveButtonClickListener(new MaterialPickerOnPositiveButtonClickListener<Long>() {
        @Override
        public void onPositiveButtonClick(Long selection) {
           //....
           Calendar calendar = Calendar.getInstance(TimeZone.getTimeZone("UTC"));
           calendar.setTimeInMillis(selection);
           SimpleDateFormat format = new SimpleDateFormat("yyyy MM dd");
           String formattedDate  = format.format(calendar.getTime());
        }
    });

In kotlin:

materialDatePicker.addOnPositiveButtonClickListener {
    val utc = Calendar.getInstance(TimeZone.getTimeZone("UTC"))
    utc.timeInMillis = it
    val format = SimpleDateFormat("yyyy-MM-dd")
    val formatted: String = format.format(utc.time)        
}

If you want to change the MaterialPicker date format then use the below code this code is working for me.

MaterialDatePicker<Long> materialDatePicker=materialDateBuilder.build();
materialDatePicker.addOnPositiveButtonClickListener(new MaterialPickerOnPositiveButtonClickListener<Long>() {
        @Override
        public void onPositiveButtonClick(Long selection) {
            // Get the offset from our timezone and UTC.
            TimeZone timeZoneUTC = TimeZone.getDefault();
            // It will be negative, so that's the -1
            int offsetFromUTC = timeZoneUTC.getOffset(new Date().getTime()) * -1;
            // Create a date format, then a date object with our offset
            SimpleDateFormat simpleFormat = new SimpleDateFormat("yyyy-MM-dd", Locale.US);
            Date date = new Date(selection + offsetFromUTC);

            mEt_last_date_to_apply.setText(simpleFormat.format(date));
        }
    });

My solution:

   val builder = MaterialDatePicker.Builder.datePicker()
    builder.setTitleText("Select a Date")
    val picker = builder.build()
    tv_rw_startDate.setOnClickListener {
        picker.show(activity?.supportFragmentManager!!, picker.toString())
        picker.addOnPositiveButtonClickListener {
            val calendar = Calendar.getInstance(TimeZone.getTimeZone("UTC"))
            calendar.time = Date(it)
            tv_rw_startDate.text = "${calendar.get(Calendar.DAY_OF_MONTH)}/ " +
                    "${calendar.get(Calendar.MONTH) + 1}/${calendar.get(Calendar.YEAR)}"
        }
    }

You should use SimpleDateFormat to format date according to your choice.

@Override
public void onDateSet(DatePickerDialog view, int Year, int Month, int Day) {

    Calendar selectedDate = Calendar.getInstance().set(Year,Month,Day);
    DateFormat formatter = new SimpleDateFormat("dd-MM-yyyy");
    String formatedDate = formatter.format(selectedDate );
    //to sting desired format date
    Toast.makeText(MainActivity.this, formatedDate , Toast.LENGTH_LONG).show();
}

Happy Coding !
