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("soszm.edupage/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("soszm.edupage/substitution/?"); return v; } }
