Setting Locale Programmatically not working?

I have an activity where I programmatically set the locale to "de" and it doesn't work as expected and displays the default language (English text) that is manually set. Please help

public void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanc开发者_运维问答eState);  
        //Programmatically sets the locale and language  
        Locale locale = new Locale("de");  
        Locale.setDefault(locale);  
        Configuration config = new Configuration();  
        config.locale = locale;   
        getBaseContext().getResources().updateConfiguration(config,getBaseContext().getResources().getDisplayMetrics());   

       Toast.makeText(getApplicationContext(),Locale.getDefault().getDisplayLanguage(),Toast.LENGTH_LONG).show();  

        setContentView(R.layout.main);  
Intent intent=new Intent(LatestLocalizationActivity.this,AnotherActivity.class);  
       startActivity(intent);  
}

had you add the Strings.xml file in res->value-de folder?

public void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        //Programmatically sets the locale and language
                    setContentView(R.layout.main); 
                    config = getBaseContext().getResources().getConfiguration(); 
                    locale = new Locale("de");
                    Locale.setDefault(locale);
                    config.locale = locale;
                    getBaseContext().getResources().updateConfiguration(config, getBaseContext().getResources().getDisplayMetrics());
                    refresh();



       Toast.makeText(getApplicationContext(),Locale.getDefault().getDisplayLanguage(),Toast.LENGTH_LONG).show();  


}



@Override
    public void onConfigurationChanged(Configuration newConfig) {
        Configuration config = getBaseContext().getResources().getConfiguration();
      // refresh your views here
        Locale.setDefault(locale);
        config.locale = locale;
      super.onConfigurationChanged(newConfig);
    }



private void refresh() {
        finish();
        Intent myIntent = new Intent(yourActivity.this, yourActivity.class);
        startActivity(myIntent);
    }

This worked for me:

public static void changeLocale(Context context, Locale locale) {
    Configuration conf = context.getResources().getConfiguration();
    conf.locale = locale;
    Locale.setDefault(locale);

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
        conf.setLayoutDirection(conf.locale);
    }

    context.getResources().updateConfiguration(conf, context.getResources().getDisplayMetrics());
}

please use your ACTIVITY CONTEXT and not your application context.

Note that while you may be able to hack on things to kind-of get something like this to work, Android does not currently support doing this in a robust way. In particular, the framework works the current configuration in the resources, and will update it when it thinks appropriate. You will be fighting with this, and it is unlikely you are going to be able to have no situations where the configuration reverts back to the system locale.
