I'd like to have webview which saves state in Fragment. What I want. I want to save state on my webview in fragment when I switch the Fragment by Navigation Drawer. I found some co

Solution 1:

You could simply add this Methods to your Fragment like this:

publicclassZastupovanieextendsSherlockFragment{

    Context context;
    privateWebView myWebView

    @OverridepublicvoidonSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        myWebView.saveState(outState);
    }

    @OverridepublicvoidonActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        myWebView.restoreState(savedInstanceState);
    }

    @OverridepublicViewonCreateView(LayoutInflater inflater, ViewGroup group, Bundle saved)
        {
        View v = inflater.inflate(R.layout.zastupovanie, group, false);
        final ProgressDialog pd = ProgressDialog.show(getActivity(),  "", "Prosím čakajte. Prebieha načítavanie... ", true);

        myWebView = (WebView) v.findViewById(R.id.zastupovanie2);
        myWebView.setWebViewClient(newWebViewClient() {
            @OverridepublicvoidonPageFinished(WebView view, String url) {
                pd.dismiss();
            }
        });

        myWebView.getSettings().setBuiltInZoomControls(false); 
        myWebView.getSettings().setSupportZoom(false);
        myWebView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);   
        myWebView.getSettings().setJavaScriptEnabled(true);
        myWebView.getSettings().setAllowFileAccess(true); 
        myWebView.getSettings().setDomStorageEnabled(true);

        myWebView.getSettings().setDefaultZoom(ZoomDensity.FAR);

        myWebView.loadUrl("http://soszm.edupage.org/substitution/?");

        return v;
        }

    }

Solution 2:

Webview in BottomNavigationView

I am using web-view in one of the fragments in BottomViewNavigation. The solution provided by @Rafael T is a solid one. But onSaveInstanceState() is not called when you navigate to another Fragment in BottomNavigationView. So I saved and restore the state of Webview like this.

classMyFragmentextendsFragment {

    privateBundle webviewstate;
    privateWebview mywebview;

    // Saving state@OverridepublicvoidonPause(){
       super.onPause();
       webviewstate = newBundle();
       mywebview.saveState(webviewstate);
    }

    @OverridepublicViewonCreateView(LayoutInflater inflater, ViewGroup parent, Bundle savedInstanceState){

       if(webviewstate==null){
            myWebView.loadUrl("http://soszm.edupage.org/substitution/?");  //Load the page for first time
       }else{
            myWebView.restoreState(webviewstate);    // Restore the state
       }

    }

}
