Question

I want to change the language in my app programatically.
The first onCreate(Bundle) method works and the images are displayed in chinese.
The second doesnt work. What do I have to insert in the “TODO” comment? I want to change the language AFTER the view was created and want to update it.

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    TranslationHelper.changeLanguage(this, Locale.CHINESE);
    setContentView(R.layout.main_activity);
    doBindService();
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main_activity);
    TranslationHelper.changeLanguage(this, Locale.CHINESE);
    // TODO recreate view to display chinese version
    doBindService();
}

The first sample works because it changes locale before setContentView method is called. You need to insert changeLanguage before setContentView.
All views are already inflated after setContentView so changing locale at this point will have no effect. You need to update it manually if you want to change the language after the view was created.
