how to show all friends names in list view

Question

I want to show friend list after log in to facebook through my app in a ListView. But my code is not working. I have also used classes like friendsArrayAdapter. I have used following code

protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.friendlist_screen);
    facebook = new Facebook(APP_ID);
    mAsyncRunner = new AsyncFacebookRunner(facebook);

    lv = (ListView) findViewById(R.id.friendsList);
    friendsArrayAdapter = new FriendsArrayAdapter(this, R.layout.rowlayout, friends);
    lv.setAdapter(friendsArrayAdapter);
}

FriendsRequestListener.class

public class FriendsRequestListener implements com.facebook.android.AsyncFacebookRunner.RequestListener {

    public void onComplete(final String response, Object state) {
        mSpinner.dismiss();
        try {
            // process the response here: executed in background thread
            Log.d("Facebook-Example-Friends Request", "response.length(): " + response.length());
            Log.d("Facebook-Example-Friends Request", "Response: " + response);

            final JSONObject json = new JSONObject(response);
            JSONArray d = json.getJSONArray("data");
            int l = (d != null ? d.length() : 0);
            Log.d("Facebook-Example-Friends Request", "d.length(): " + l);

            for (int i = 0; i < l; i++) {
                JSONObject o = d.getJSONObject(i);
                String n = o.getString("name");
                String id = o.getString("id");
                Friend f = new Friend();
                f.id = id;
                f.name = n;
                friends.add(f);
            }
            // Only the original owner thread can touch its views
            FrndActivity.this.runOnUiThread(new Runnable() {
                public void run() {
                    friendsArrayAdapter = new FriendsArrayAdapter(
                        FrndActivity.this, R.layout.rowlayout, friends);
                    lv.setAdapter(friendsArrayAdapter);
                    friendsArrayAdapter.notifyDataSetChanged();
                }
            });
        } catch (JSONException e) {
            Log.w("Facebook-Example", "JSON Error in response");
        }
    }

Please sugest how to show the names in ListView and if I need to make any other classes for this thing?

Where is the problem? Is it in your JSON Object or in your adapter? Did you see if the Facebook result is the friends list? Or the problem is in the Adapter? — Renan Bandeira, Aug 08 '13 at 11:27
But do you have the friends stored? Is it in friends variable? — Renan Bandeira, Aug 08 '13 at 11:41
no i don,t have any stored friends. i want to show my facebook friends in a list view after successful login — Nidhi, Aug 08 '13 at 11:45
Ok, gotcha. So your problem isn't in List, is in Facebook API. Take a look at [this](http://stackoverflow.com/questions/10198965/android-get-facebook-friends-who-have-app-downloaded/15196047#15196047) — Renan Bandeira, Aug 08 '13 at 11:54

actually i am using this code now but don't know where the problem is! — Nidhi, Aug 12 '13 at 04:18
error in logcat: I/dalvikvm(5443): Could not find method android.support.v4.content.LocalBroadcastManager.getInstance, referenced from method com.facebook.Session.postActiveSessionAction and it also shows " W/Facebook-Example(5443): JSON Error in response" — Nidhi, Aug 12 '13 at 08:31
Here i pasted all codes with list of friends... http://mahahari777.blogspot.in/2013/08/how-to-retrieve-facebook-contacts-and.html — Hariharan, Aug 12 '13 at 08:57
this is really useful. thank you. but i am using two different activities ,one for login button and other for list view. and now if i am putting "mAsyncRunner.request("me/friends", new FriendsRequestListener());" in onComplete() method of login,it suggests to make a class FriendsRequestListener. but i made dis one in list view activity. how can i link these both.i use that class as above. — Nidhi, Aug 12 '13 at 09:11
Use arraylist as public static ArrayList friends_list; after getting details i toast as success after that add Intent ide = new Intent(MainActivity.this,Next.class); ide.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); startActivity(ide); then use the public arraylist in Next.class and display as listview.. — Hariharan, Aug 12 '13 at 09:21
i have used only one listview in frnd list screen. i want that when login button is clicked ,after successful login,the second activity opens and also the frnd list of user shows in list view. i have used row layout text box for the name only that would save in the list view — Nidhi, Aug 13 '13 at 06:06
I have edited and pasted new version of the code here http://pastebin.com/5fCRxtLd — Hariharan, Aug 13 '13 at 06:16
you have declared two intents.. and in first intent you have not passed the friends data. So, remove the first intent which will make it work fine. — Hariharan, Aug 13 '13 at 06:17
i am facing a prblm.When the user is on the FriendList screen and hits back,the user is taken to the login screen but the login button doesn't work after these steps.and also When the user after logging in goes to the background the app asks for the user to login again.This is incorrect,the user should be able to stay logged in after coming back to foreground and the same screen should show up where the user left. pls suggest — Nidhi, Aug 13 '13 at 09:17
use boolean for that if logout means take that as false if does't logout means take as true... — Hariharan, Aug 13 '13 at 10:01
