在片段中保存状态WebView [英] Save state WebView in Fragment

问题描述

我想使用webview将状态保存在Fragment中.我想要的是.当我通过导航抽屉切换片段"时，我想在片段中的Webview上保存状态.我找到了一些代码来保存状态，但实际上我不知道在哪里写.有人可以帮我吗?对不起，我的英语.

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 code to save the state, but actually I don't know where to write it. Can someone help me with that, please? I am sorry for my English.

这是保存状态的代码

@Override
public void onSaveInstanceState(Bundle outState) {
   super.onSaveInstanceState(outState);
   mWebView.saveState(outState);
}

@Override
public void onActivityCreated(Bundle savedInstanceState) {
   super.onActivityCreated(savedInstanceState);
   mWebView.restoreState(savedInstanceState);
}

这是我的代码

public class Zastupovanie extends SherlockFragment{

    private Context context;
        
    @Override
    public View onCreateView(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);
    
        final WebView myWebView = (WebView) v.findViewById(R.id.zastupovanie2);
        myWebView.setWebViewClient(new WebViewClient() {
            @Override
            public void onPageFinished(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;
    }
        
}

推荐答案

您可以像下面这样简单地将此方法添加到片段中:

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

public class Zastupovanie extends SherlockFragment{

    Context context;
    private WebView myWebView

    @Override
    public void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        myWebView.saveState(outState);
    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        myWebView.restoreState(savedInstanceState);
    }

    @Override
    public View onCreateView(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(new WebViewClient() {
            @Override
            public void onPageFinished(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;
        }

    }
