Answer 1

tl;dr

Month                             // Enum class, predefining and naming a dozen objects, one for each month of the year. 
.of( 12 )                         // Retrieving one of the enum objects by number, 1-12. 
.getDisplayName(
    TextStyle.FULL_STANDALONE , 
    Locale.CANADA_FRENCH          // Locale determines the human language and cultural norms used in localizing. 
)

java.time

Since Java 1.8 (or 1.7 & 1.6 with the ThreeTen-Backport) you can use this:

Month.of(integerMonth).getDisplayName(TextStyle.FULL_STANDALONE, locale);

Note that integerMonth is 1-based, i.e. 1 is for January. Range is always from 1 to 12 for January-December (i.e. Gregorian calendar only).

Answer 2

    public static void main(String[] args) {
    SimpleDateFormat format = new SimpleDateFormat("MMMMM", new Locale("en", "US"));
    System.out.println(format.format(new Date()));
}

Try to use this a very simple way and call it like your own func

public static String convertnumtocharmonths(int m){
         String charname=null;
         if(m==1){
             charname="Jan";
         }
         if(m==2){
             charname="Fev";
         }
         if(m==3){
             charname="Mar";
         }
         if(m==4){
             charname="Avr";
         }
         if(m==5){
             charname="Mai";
         }
         if(m==6){
             charname="Jun";
         }
         if(m==7){
             charname="Jul";
         }
         if(m==8){
             charname="Aou";
         }
         if(m==9){
             charname="Sep";
         }
         if(m==10){
             charname="Oct";
         }
         if(m==11){
             charname="Nov";
         }
         if(m==12){
             charname="Dec";
         }
         return charname;
     }

I would use SimpleDateFormat. Someone correct me if there is an easier way to make a monthed calendar though, I do this in code now and I'm not so sure.

import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.GregorianCalendar;


public String formatMonth(int month, Locale locale) {
    DateFormat formatter = new SimpleDateFormat("MMMM", locale);
    GregorianCalendar calendar = new GregorianCalendar();
    calendar.set(Calendar.DAY_OF_MONTH, 1);
    calendar.set(Calendar.MONTH, month-1);
    return formatter.format(calendar.getTime());
}

Answer 5

Just inserting the line

DateFormatSymbols.getInstance().getMonths()[view.getMonth()] 

will do the trick.

Answer 6

There is an issue when you use DateFormatSymbols class for its getMonthName method to get Month by Name it show Month by Number in some Android devices. I have resolved this issue by doing this way:

In String_array.xml

<string-array name="year_month_name">
    <item>January</item>
    <item>February</item>
    <item>March</item>
    <item>April</item>
    <item>May</item>
    <item>June</item>
    <item>July</item>
    <item>August</item>
    <item>September</item>
    <item>October</item>
    <item>November</item>
    <item>December</item>
    </string-array>

In Java class just call this array like this way:

public String[] getYearMonthName() {
        return getResources().getStringArray(R.array.year_month_names);
        //or like 
       //return cntx.getResources().getStringArray(R.array.month_names);
    } 

      String[] months = getYearMonthName(); 
           if (i < months.length) {
            monthShow.setMonthName(months[i] + " " + year);

            }

Happy Coding :)
