您好我知道有这个问题的答案。我已经尝试了所有的人，但它不工作在我的应用程序。 我开发一个应用程序，有3个片段的活性。首先片段展示了一个网站，第二个片段有ListView和第三个片段还有一个列表视图。现在，我想从第三个片段首先片段发送URL，当用户点击listitem..This是我做了什么。

Hi I know there are answers of this question. I have tried all of them but it is not working in my app. I am developing an app that has 3 Fragment activity. First fragment shows a website, second fragment has listview and third Fragment has another listview. Now I want to send URL from third fragment to first fragment when user clicks on listitem..This is what I have done.

我从这个片段到第一个片段发送字符串URL。

I am sending string url from this Fragment to first fragment.

list.setOnItemClickListener(new OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> adapter, View view, int position,
            long id) {
        FragmentC fragment = new  FragmentC();
        final Bundle bundle = new Bundle();
        bundle.putString("position", "http://www.facebook.com");            fragment.setArguments(bundle);}
});

这是第一个片段，我需要的网址，并希望在web视图中显示。

This is first fragment where I need the url and Want to show in the webview.

String url="http://www.hotelsearcher.net/";
        Bundle args = getArguments();
        if (args  != null){
        url = args.getString("position");
        }
        WebView webView= (WebView) V.findViewById(R.id.webView1);
        WebSettings webViewSettings = webView.getSettings();
        webViewSettings.setJavaScriptCanOpenWindowsAutomatically(true);
        webViewSettings.setJavaScriptEnabled(true);
        webViewSettings.setPluginState(PluginState.ON);
        webView.loadUrl(url);

当我点击列表项我什么也没看到。它不重定向我的第一个fragment.Please帮助我..

When I click on list item I don't see anything . It does not redirect me to the first fragment.Please help me..

推荐答案

使用捆绑发送字符串：

//Put the value
YourNewFragment ldf = new YourNewFragment ();
Bundle args = new Bundle();
args.putString("YourKey", "YourValue");
ldf.setArguments(args);

//Inflate the fragment
getFragmentManager().beginTransaction().add(R.id.container, ldf).commit();

在新的片段onCreateView：

In onCreateView of the new Fragment:

//Retrieve the value
String value = getArguments().getString("YourKey");
