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 :)

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

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

Just inserting the line   DateFormatSymbols getInstance   getMonths   view getMonth       will do the trick

Apparently in Android 2 2 there is a bug with SimpleDateFormat   In order to use month names you have to define them yourself in your resources    lt string-array name  month names  gt       lt item gt January lt  item gt       lt item gt February lt  item gt       lt item gt March lt  item gt       lt item gt April lt  item gt       lt item gt May lt  item gt       lt item gt June lt  item gt       lt item gt July lt  item gt       lt item gt August lt  item gt       lt item gt September lt  item gt       lt item gt October lt  item gt       lt item gt November lt  item gt       lt item gt December lt  item gt   lt  string-array gt    And then use them in your code like this          Get the month name of a Date  e g  January for the Date 2011-01-01         param date     return e g   January      public static String getMonthName Context context  Date date                   Android 2 2 has a bug in SimpleDateFormat  Can t use  MMMM  for        getting the Month name for the given Locale  Thus relying on own        values from string resources              String result            Calendar cal   Calendar getInstance        cal setTime date       int month   cal get Calendar MONTH        try           result   context getResources   getStringArray R array month names  month         catch  ArrayIndexOutOfBoundsException e            result   Integer toString month              return result
