ANDROID: Simplified Chinese and Traditional Chinese | Language change inside app

Question

I am developing application that supports three languages

1. English
2. Simplified Chinese

3. Traditional Chinese

   for that i have created two extra folders inside the res folder:

   • values-zh-rCH (for simplified Chinese)
   • values-zh-rTW (for traditional Chinese)
   • be default is values for English Language

I am using below function to change the languages `

    public void setLocale(String lang) {
       Locale myLocale = new Locale(lang);

       Resources res = getResources();

        DisplayMetrics dm = res.getDisplayMetrics();

       Configuration conf = res.getConfiguration();

        conf.locale = myLocale;

        res.updateConfiguration(conf, dm);

        Intent refresh = new Intent(this, StartMenuActivity.class);

       finish();

       startActivity(refresh);`

    }

and i am passing below values to the function

• en
• zh_CN
• zh_TW

i have also tried below values

• en
• zh_rCN
• zh_rTW

but its not working. what is the issue ? can anyone please suggest me ?

For testing purpose, I have created values-zh folder and passed zh to setLocale in that case language is being changed.

what this is not working with traditional and simplified Chinese?

You can use below piece of code to solve your problem

 public void setLocale(String lang) {
    Locale myLocale;
    if (lang.equals("zh_CN")) {
        myLocale = Locale.SIMPLIFIED_CHINESE;
    } else if (lang.equals("zh_TW")) {
        myLocale = Locale.TRADITIONAL_CHINESE;
    } else {
        myLocale = new Locale(lang);
    }

    Locale.setDefault(myLocale);
    Resources res = getResources();
    DisplayMetrics dm = res.getDisplayMetrics();
    Configuration conf = res.getConfiguration();
    conf.locale = myLocale;
    res.updateConfiguration(conf, dm);
}
