I think you can take a look to this Xamarin Forms Sample. It use RESX files.

TodoLocalized

In your code, you could create a picker with Language description. For example

    List<string> _language = new List<string>();
    List<string> _languageDescription = new List<string> ();

    // Strings used to identify RESX
    _language.Add ("it");
    _language.Add ("en");

    // Strings visualized in picker
    _languageDescription.Add (AppResources.Italian);
    _languageDescription.Add (AppResources.English);

    // Fill the picker with _languageDescription values
    Picker _pickerLanguage = new Picker ();
    _pickerLanguage.Items.Clear ();
    foreach (string language in _languageDescription)
        _pickerLanguage.Items.Add (language);

    // When I select a language, I change the AppResource.Culture value
    _pickerLanguage.SelectedIndexChanged += async (object sender, EventArgs e) => {
            if(_pickerLanguage.SelectedIndex >= 0){

                // Search the "_language" value that has the same index of selected _languageDescription value
                string myLanguage = _language [_languageDescription.FindIndex (o => o == _pickerLanguage.Items [_pickerLanguage.SelectedIndex])];

                // Modify the culture
                AppResources.Culture = new CultureInfo (myLanguage);

            }
        };

Now you should refresh your page to see strings with new language

Hope this help
