    copied!<p>I am currently building an application that downloads data from facebook using their graph API.</p> <p>I am facing a very weird problem.. The data that I get from facebook is really huge so I use SqliteDatabase transaction to insert everything at once.</p> <p>Now I have two table where the data is being inserted one which is called event and the other which is called event_friend</p> <p>I created a list view whose adapter contains a query which is the join of both the above tables. Now every time a transaction finishes some number of rows are added in both the tables as a result the listView should also update. I found out that to do this we need to call notifyDataSetChanged of the adapter. I even tried doing that by sending a broadcast intent when the transaction is over and then calling notifyDataSetChanged but there were no rows in the listview.</p> <p>However when the activity resumes then the listView is filled with rows.</p> <p>Here is the relevant snippet from OnCreate</p> <blockquote> <blockquote> <p>Cursor c = managedQuery(CrowdSpottrProvider.CONTENT_URI_FRIENDS_POPULAR_VIRTUAL_TABLE, null, null, null, null);</p> <p>mListAdapterFriends = new EventsFriendsAdapter(this, R.layout.event_item, c, new String[]{"name", "friends", "start_time", "end_time"}, new int[] {R.events_list.event_name, R.events_list.number_of_friends_attending}, 2); mListView.setAdapter(mListAdapterFriends);</p> <p>mReciever = new BroadcastReceiver() {</p> <pre><code> @Override public void onReceive(Context context, Intent </code></pre> <p>intent) {</p> <pre><code> mListAdapterFriends.notifyDataSetChanged(); } }; registerReceiver(mReciever, new IntentFilter("events_added")); </code></pre> </blockquote> </blockquote> <p>Also the thread added entries as follows:</p>
