How to get a list of data in an updated record?

Question

I created a program in which I collect a list of all my friends on Facebook with their name, add and profile, but I decided to use the tabs in my existing program, so I also wrote code for this, but whenever I run my application, every time I get tabs but don’t get friends list ..

In my case, I am not getting ActivityList Activity data in the TabSample class, why?

SplashScreen.java: -

private final static int FACEBOOK_AUTHORIZE_ACTIVITY_RESULT_CODE = 0; private final static int FRIENDS_LIST_ACTIVITY = 1; public void onRequestReceived(int result, String message) { Log.d(LOG_TAG, "onRequestReceived(" + result + ")"); if(isFinishing()) return; switch (result) { case FacebookRequest.COMPLETED: Intent intent = new Intent(this, com.chr.tatu.sample.friendslist.TabSample.class); intent.putExtra("FRIENDS", message); while (System.currentTimeMillis() - startTime < DELAY) { try { Thread.sleep(50); } catch (Exception e) {} } startActivityForResult(intent, FRIENDS_LIST_ACTIVITY); isLoadingFriends = false; break; case FacebookRequest.IO_EXCEPTION: case FacebookRequest.FILE_NOT_FOUND_EXCEPTION: case FacebookRequest.MALFORMED_URL_EXCEPTION: case FacebookRequest.FACEBOOK_ERROR: FacebookUtility.displayMessageBox(this, this.getString(R.string.friends_error)); onButton(); break; } } 

FriendsList.java: -

  public class FriendsList extends Activity implements FacebookRequest, OnItemClickListener { private static String LOG_TAG = "FriendsList"; private static JSONArray jsonArray; private static ListView friendsList; private Handler mHandler; private Button saveGreeting; public void onCreate(Bundle savedInstanceState) { mHandler = new Handler(); super.onCreate(savedInstanceState); try { requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS); getActionBar().hide(); } catch (Exception e) {} setContentView(R.layout.friends_list_screen); try { setProgressBarIndeterminateVisibility(false); } catch (Exception e) {} init(); saveGreeting = (Button) findViewById(R.id.greeting); saveGreeting.setOnClickListener(new OnClickListener() { public void onClick(View v) { customGreeting(v); } }); } public void customGreeting(View v) { Intent myWebLink = new Intent(android.content.Intent.ACTION_VIEW);

} catch (JSONException e) { Log.e(LOG_TAG, "getJSONObject: " + e.getMessage()); friendItem.friendName.setText(""); friendItem.friendDob.setText(""); } listofshit.put(position, friendItem); return convertView; } public int getPositionForSection(int position) { return position; } public int getSectionForPosition(int position) { return position; } public Object[] getSections() { return sections; } } class FriendItem { TextView friendDob; int id; ImageView friendPicture; TextView friendName; RelativeLayout friendLayout; } } 

TabSample.java: -

  public class TabSample extends TabActivity { /** Called when the activity is first created. */ public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.tabmain); setTabs() ; } private void setTabs() { addTab("All", R.drawable.tab_menu, FriendsList.class); addTab("Current Month", R.drawable.tab_offers, FriendsList.class); addTab("Current Week", R.drawable.tab_location, FriendsList.class); addTab("Today", R.drawable.tab_reservation, FriendsList.class); } private void addTab(String labelId, int drawableId, Class<?> c) { TabHost tabHost = getTabHost(); Intent intent = new Intent(this, c); TabHost.TabSpec spec = tabHost.newTabSpec("tab" + labelId); View tabIndicator = LayoutInflater.from(this).inflate(R.layout.tab_indicator, getTabWidget(), false); TextView title = (TextView) tabIndicator.findViewById(R.id.title); title.setText(labelId); ImageView icon = (ImageView) tabIndicator.findViewById(R.id.icon); icon.setImageResource(drawableId); spec.setIndicator(tabIndicator); spec.setContent(intent); tabHost.addTab(spec); } } 

Please tell me where I should add this code:

 Bundle extras = getIntent().getExtras(); String response = extras.getString("FRIENDS"); Log.d(LOG_TAG, "onCreate()" + response); try { jsonArray = new JSONArray(response); } catch (JSONException e) { FacebookUtility.displayMessageBox(this, this.getString(R.string.json_failed)); } 

and any other code should go from the FriendsList class to the TabSample class
