I want to use a spinner/dropdownlist to open a website on a webview

Question

I am trying to make a timetable app for my school and I want to use a spinner with all classes in it. When you select your class I want it to open a specific URL with the timetable in it. I tried so many ways but it's just not working.. I prefer not to use a "submit" button with it.. can somebody help me?

Edit: think I figured it out, but here's my next problem: I want it to open a website with a if statement but when I try this it gives me an error: The method findViewById(int) is undefined for the type CustomOnItemSelectedListener

public class CustomOnItemSelectedListener implements OnItemSelectedListener {


public void onItemSelected(AdapterView<?> parent, View view, 
        int pos, long id) { 
if (parent.getItemAtPosition(pos) == "h5c") {
WebView myWebView = (WebView) findViewById(R.id.webView1);
}

}


public void onNothingSelected(AdapterView<?> parent) {
    // Another interface callback
}

}

Really hope u guys understand, since I am a noob at this :p

Try this out. This is the complete answer to your query.

Also give internet permissions in AndroidManifest

private WebView wv1;
String url;

Spinner spinner;
private String[] spinner_and_webview = {"Learn Spinner", "Learn WebView"};

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    spinner = (Spinner) findViewById(R.id.spinner);
    ArrayAdapter<String> adapter0 =
            new ArrayAdapter<String>(MainActivity.this,
                    android.R.layout.simple_spinner_item, spinner_and_webview);
    adapter0.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinner.setAdapter(adapter0);
    spinner.setOnItemSelectedListener(onItemSelectedListener0);

    wv1 = (WebView) findViewById(R.id.webView);
    wv1.setWebViewClient(new MyBrowser());
}

AdapterView.OnItemSelectedListener onItemSelectedListener0 =
        new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parent, View view,
                                       int position, long id) {

                String sp1 = String.valueOf(spinner.getSelectedItem());
                if (sp1.contentEquals("Learn Spinner")) 
                    url = "http://developer.android.com/guide/topics/ui/controls/spinner.html";
                if (sp1.contentEquals("Learn WebView")) 
                    url = "http://developer.android.com/reference/android/webkit/WebView.html";
                wv1.getSettings().setLoadsImagesAutomatically(true);
                wv1.getSettings().setJavaScriptEnabled(true);
                wv1.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
                wv1.loadUrl(url);
            }
            @Override
            public void onNothingSelected(AdapterView<?> parent) {
            }
        };
private class MyBrowser extends WebViewClient {
    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        view.loadUrl(url);
        return true;
    }
}
