How to send data from one Fragment to another Fragment?

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.

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);}
});

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);

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

Use Bundle to send String:

//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();

In onCreateView of the new Fragment:

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

You have to attach your bundle to your fragment.

fragment.setArguments(bundle);

and after that change or replace the new fragment.

You have to be sure that the String is in the new Fragment. Debugging!!

You can send data by two ways First when you want to start that fragment while sending data

SecondFragment ldf = new SecondFragment ();
Bundle args = new Bundle();
args.putString("YourKey", "YourValue");
ldf.setArguments(args);

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

Second, when you want to send data without open your fragment

FragmentTransaction ft = mFragmentManager.beginTransaction();
ft.add(R.id.fragContainer1, new ModelListFragment(), FRAG_MODEL_LIST);
ft.add(R.id.fragContainer2, new TrimListFragment(), FRAG_TRIM_LIST);
ft.commit();

Fragment fragment = mFragmentManager.findFragmentByTag(MainActivity.FRAG_MODEL_LIST);
Log.d("MY", "found fragment: " + (fragment != null));

1.If fragments are hosted by same activity- You cannot cast an intent to Fragment. Fragment acts as a part of Activity, it is not an activity by itself. So to share a string between fragments you can declare a static String in Activity. Access that string from Fragment A to set the value and Get the string value in fragment B.

2.Both fragments are hosted by different Activities- Then you can use putExtra to pass a string from Fragment A of Activity A to Activity B. Store that string in Activity B and use it in Fragment B.
