How to send data from one Fragment to another Fragment?

Question

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");

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.
