print separately start and end date selected from daterangepicker method in android and print these in the form of date format

Question

daterangepicker in android helps us to select a range of dates and i want to show start date and end date of this range separately in different textviews.I don't know how to do it. private Button bt1; private TextView tv1;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    
    bt1 = findViewById(R.id.bt1);
    tv1 = findViewById(R.id.tv1);

    MaterialDatePicker.Builder<Pair<Long, Long>> builder = MaterialDatePicker.Builder.dateRangePicker();
    final MaterialDatePicker materialDatePicker = builder.build();
    
    bt1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            materialDatePicker.show(getSupportFragmentManager(),"date picker");
        }
    });

    materialDatePicker.addOnPositiveButtonClickListener(new MaterialPickerOnPositiveButtonClickListener() {
        @Override
        public void onPositiveButtonClick(Object selection) {
           tv1.setText(materialDatePicker.getHeaderText());
        }
    });
}
