Android: change year directly in Material-calendarview

Question

I am using https://github.com/prolificinteractive/material-calendarview

Now he changes the month by pressing the right or left arrow

How can I change the year directly, and not change the month. Is this possible by default for Android by default. Below is my code for prolificinteractive - calendar

public class ActivityCalendar extends AppCompatActivity implements OnDateSelectedListener, OnMonthChangedListener { private static final DateFormat FORMATTER = SimpleDateFormat.getDateInstance(); private MaterialCalendarView widget; private String zodiacSign = ""; private HashMap<String,Integer> hashMapMonth = new HashMap<>(); @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.layout_calendar); widget = (MaterialCalendarView)findViewById(R.id.calendarView); widget.setOnDateChangedListener(this); widget.setOnMonthChangedListener(this); } @Override public void onDateSelected(@NonNull MaterialCalendarView widget, @Nullable CalendarDay date, boolean selected) { String strDate = getSelectedDatesString(); Intent returnIntent = new Intent(); returnIntent.putExtra(TagClass.BIRTH_DATE, strDate); setResult(Activity.RESULT_OK, returnIntent); finish(); } @Override public void onMonthChanged(MaterialCalendarView widget, CalendarDay date) { //noinspection ConstantConditions } private String getSelectedDatesString() { CalendarDay date = widget.getSelectedDate(); if (date == null) { return "No Selection"; } return FORMATTER.format(date.getDate()); } } 

layout.xml

 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" xmlns:app="http://schemas.android.com/apk/res-auto" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".ActivityCalendar"> <com.prolificinteractive.materialcalendarview.MaterialCalendarView android:id="@+id/calendarView" android:layout_width="match_parent" android:layout_height="wrap_content" /> </LinearLayout>

It does not seem possible with this library, as it is now.

To do this, you will need to download sources from github and add it to your project as a library module.

Then I expect that changes will be needed, at least in these components:

• MaterialCalendarView.java to change adapter naming or usage in ViewPager.OnPageChangeListener
• CalendarPagerAdapter.java to specify elements of the year instead of months.

I also got the impression that making these changes would also lead to a mayor refactor in the library.
