How to convert english "abc123 " digits to arabic "ابث١٢٣ " dynamically android

Question

UPDATED

i have been looking for solution but couldnt found it yet ..

i have tried this

// Check for language
    String tempLang = Locale.getDefault().getLanguage();
    if (tempLang == "ar") {
        Locale AR_LOCALE_EAST_NUMBERS = new Locale.Builder().setLanguageTag("ar-u-nu-arab").build();
        Locale.setDefault(AR_LOCALE_EAST_NUMBERS);

        firstName.setKeyListener(DigitsKeyListener.getInstance(getActivity().getString(R.string.input_charatars_only_valid)));
    } else {

        firstName.setKeyListener(DigitsKeyListener.getInstance(getActivity().getString(R.string.input_charatars_only_valid)));
    }

1. first of all it gives error of API .. it says to use

   @TargetApi(Build.VERSION_CODES.LOLLIPOP)

2. i want to use it for 15 API as my minSdk is 15

is it correct or any changes needed

Answer 1

You can do it with replaceAll.

First, create a method:

    public String convertToArabic(int value)
{
    String newValue = (((((((((((value+"")
            .replaceAll("1", "١")).replaceAll("2", "٢"))
            .replaceAll("3", "٣")).replaceAll("4", "٤"))
            .replaceAll("5", "٥")).replaceAll("6", "٦"))
            .replaceAll("7", "٧")).replaceAll("8", "٨"))
            .replaceAll("9", "٩")).replaceAll("0", "٠"));
    return newValue;
}

And usage:

String myArabicNumber= convertToArabic(123);
Log.d("output",myArabicNumber);

output:

١٢٣ 

UPDATE:

you can do it by concatenating them:

    String space = "\u00A0"; //space
    String myArabicCharacter = getResources().getString(R.string.help);
    String myArabicNumber= convertToArabic(123);
    String fullHomework = myArabicCharacter+space+myArabicNumber;
    Log.d("output",fullHomework);

output:

     راهنما ١٢٣
