I'm trying to fill a spinner in a fragment layout with an array of strings that I get returned from a Javascript function of my WebView page.

This is my scenario: I'm in fragment1 which has a webview1. I click on something in the webview1 and I go to fragment2 which has another WebView2. I want to fill a spinner in fragment2 with an array returned from a function wrote in the page that is being loaded in WebView2.

js function wrote in the page that is gonna load in WebView2:

function test(){

    var cars = ["Saab", "Volvo", "BMW"];

    window.JSInterface.callback(cars);

}

And this is my fragment2 code:

public View onCreateView(LayoutInflater inflater, ViewGroup container,

                         Bundle savedInstanceState) {

    // Inflate the layout for this fragment

    view = inflater.inflate(R.layout.fragment_edificio, container, false);



    ...



    wv.getSettings().setJavaScriptEnabled(true);

    Fragment2.JavaScriptInterface jsInterface = new 

                   Fragment2.JavaScriptInterface(getActivity());

    wv.addJavascriptInterface(jsInterface, "JSInterface");

    wv.loadUrl("file:///android_asset/"+idEdificio+"-p0.html"); // point it to the SVG

    wv.setBackgroundColor(0x00000000);



    wv.setWebChromeClient(new WebChromeClient() {



        public void onProgressChanged(WebView view, int progress) {

            progressBar.setProgress(progress);

            if(progress == 100) {

                //wait for page to load



                wv.loadUrl("javascript:test()");                   

            }

        }

    });





    return view;

}

And this is my JSInterface for callbacks from WebView page

public class JavaScriptInterface {

    private Activity activity;



    public JavaScriptInterface(Activity activity) {

        this.activity = activity;

    }



    @JavascriptInterface

    public void loadEdificio(){



        loadFragment(new FragmentEdificio());

    }

    @JavascriptInterface

    public void callback(String value) {

        ArrayAdapter<String> adapter = new ArrayAdapter<String>(

                getActivity(), android.R.layout.simple_spinner_item, value);



        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

        spinner.setAdapter(adapter);

    }

}

What happens is that i get the array returned but the spinner doesn't fill up, but if put these lines in the OnCreateView() the spinner does fill up :

String value = {"value1", "value2"};

ArrayAdapter<String> adapter = new ArrayAdapter<String>(

            getActivity(), android.R.layout.simple_spinner_item, value);



adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

spinner.setAdapter(adapter);;

From what I undertood is that the callbacks from the webview are handled in a different thread and what I'm trying to do cannot be done. Is there a different way to do this? Or am I missing something?

Thanks in advance!
