DatePickerDialog month name shows M+0+Month number

Question

I am using DatePickerDialog. But month name are showing wrong, i.e. instead of January 2019 it is showing 2019 M01 and February as 2019 M02 and so on. My problem is that default view for calendarView is showing the month numbers like that, i am not changing or setting anything in this views, normally it must show something like : 2019 January.

How can i fix this issue?

My Layout:

MY LAYOUT IMAGE

<CalendarView
        android:id="@+id/calender"
        android:layout_width="320dp"
        android:layout_height="300dp"/>

My Code:

  CalendarView calendarView = view.findViewById(R.id.calender);
    calendarView.setOnDateChangeListener(new CalendarView.OnDateChangeListener() {
        @Override
        public void onSelectedDayChange(@NonNull CalendarView view, int year, int month, int dayOfMonth) {
            saveDate(year, month, dayOfMonth);
        }
    });

I have tested with above code and no issue found. Try to comment other operation on calendar view if so you are doing in activity. — Ankit ihelper Sharma, May 21 '19 at 12:22
@Ankitihelpersharma i did nothing more with calendar and calendarview in my app, the problem is that it works correctly in other apps, i want to know what affects calendarview to behave like that — Mohammad Behnam, May 22 '19 at 04:20
Try to create new project and test whether same issue occur or not — Ankit ihelper Sharma, May 22 '19 at 04:23

this is happened due to misconfiguration of Locale you must set Locale to en to get January like month

the following code will use to set locale

fun setLocale(context: Context, language: String): Context {
        persist(language, context)
        return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            updateResources(context, language)
        } else updateResourcesLegacy(context, language)
    }

@TargetApi(Build.VERSION_CODES.N)
private fun updateResources(context: Context, language: String): Context {
    val locale = Locale(language)
    Locale.setDefault(locale)
    val configuration = context.resources.configuration
    configuration.setLocale(locale)
    return context.createConfigurationContext(configuration)
}

private fun updateResourcesLegacy(context: Context, language: String): Context {
    val locale = Locale(language)
    Locale.setDefault(locale)
    val resources = context.resources
    val configuration = resources.configuration
    configuration.locale = locale
    resources.updateConfiguration(configuration, resources.displayMetrics)
    return context
}

Somewhere in your base Activity

override fun attachBaseContext(newBase: Context) {
    super.attachBaseContext(setLocale(context, "en"))//or other language
   }

Thanks, mate, I was also setting the wrong language ```(english instead of 'en')```. — abdullahicyc, Oct 30 '22 at 14:40

Please follow this

public class MainActivity extends AppCompatActivity {

    Calendar calendar;
    CalendarView calendarView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        calendar = Calendar.getInstance();


        calendar.set(Calendar.MONTH, Calendar.MAY);
        calendar.set(Calendar.DAY_OF_MONTH, 9);
        calendar.set(Calendar.YEAR, 2019);


        calendar.add(Calendar.DAY_OF_MONTH, 1);
        calendar.add(Calendar.YEAR, 1);


        calendarView = findViewById(R.id.calendarView);


        calendarView.setOnDateChangeListener(new CalendarView.OnDateChangeListener() {
            @Override
            public void onSelectedDayChange(@NonNull CalendarView calendarView, int i, int i1, int i2) {

                String msg = "Selected date Day: " + i2 + " Month : " + (i1 + 1) + " Year " + i;
                Toast.makeText(getApplicationContext(), msg, Toast.LENGTH_SHORT).show();


            }
        });


    }
}
