where currentPage is the page of your datasource that should be added to your list, and threshold is the number of list items (counted from the end) that should, if visible, trigger the loading process. If you set threshold to 0, for instance, the user has to scroll to the very end of the list in order to load more items.

(optional) As you can see, the "load-more check" is only called when the user stops scrolling. To improve usability, you may inflate and add a loading indicator to the end of the list via listView.addFooterView(yourFooterView). One example for such a footer view:ListAdapter needs to know the full count up front, and most such adapters are set up to wrap the full content (e.g., CursorAdapter wraps a Cursor, which holds the full result set of a query). My guess is that Isaac is interested in putting an Android front-end on a Web service API that uses paging, so you don't necessarily know how many there are up front and need to do an HTTP fetch each time to get a new batch.

I think the list adaptor can change it's size (or data set). So when it is asked for the last item it triggers off a fetch. Obviously from a UI point of view this is bad. You should be trying to hide the latency from the user by fetching before the user gets to the end.   hacken Jul 5 '09 at 0:47
  	  	
This was my first idea, but it does seem messy - a ListView will sometimes request the last item much before it is needed.   Isaac Waller Jul 5 '09 at 18:48

I've been working in another solution very similar to that, but, I am using a footerView to give the possibility to the user download more elements clicking the footerView, I am using a "menu" wich is shown above the ListView and in the bottom of the parent view, this "menu" hides the bottom of the ListView, so, when the listView is scrolling the menu disappear and when scroll state is idle, the menu appear again, but when the user scrolls to the end of the listView, I "ask" to know if the footerView is shown in that case, the menu doesn't appear and the user can see the footerView to load more content. Here the code:

Running the app now should show your previous ListView, with a nice box above. In order to make that box do something, we need to take the input from it, and make that input filter the list. While a lot of people have tried to do this manually, most ListView Adapter classes come with a Filter object that can be used to perform the filtering automagically. We just need to pipe the input from the EditText into the Filter. Turns out that is pretty easy. To run a quick test, add this line to your onCreate() call

adapter.getFilter().filter(s);
Notice that you will need to save your ListAdapter to a variable to make this work - I have saved my ArrayAdapter<String> from earlier into a variable called 'adapter'.
ohe, when you say R.id.something, the something exists in id because you said android:id="@+id/search_box". If you say android:id="@+building_list/search_box" then in the code you can call findViewById(R.building_list.search_box); What is the top level exception you are getting? This code is copied w/o a test compile, so I likely left at least one error in there somewhere   Hamy Feb 8 '10 at 15:23
  	  	
Hi Hamy, you referenced "@+building_list/search_box" in the code with "filterText = (EditText) findViewById(R.id.search_box);" That's why I was wondering.   j7nn7k Feb 11 '10 at 6:36

The forceclose occorrs when starting to type in. Part of the error: ERROR/AndroidRuntime(188): java.lang.NullPointerException 02-11 07:30:29.828: ERROR/AndroidRuntime(188): at xxx.com.ListFilter1.onTextChanged(ListFilter.java:46) 02-11 07:30:29.828: ERROR/AndroidRuntime(188): at android.widget.TextView.sendOnTextChanged(TextView.java:6102) 02-11 07:30:29.828: ERROR/AndroidRuntime(188): at android.widget.TextView.handleTextChanged(TextView.java:6143) 02-11 07:30:29.828: ERROR/AndroidRuntime(188): at android.widget.TextViewChangeWatcher.onTextChanged(TextView.java:6286)   j7nn7k Feb 11 '10 at 6:38
  	  	
Johe, Oops - it looks like I was trying to modify the code to get rid of the @+building_list (because that's a point of confusion) but I didnt catch it everywhere. Thanks for the tip Just changing it to @+id should fi
Next step is to get the input from the EditText. This actually takes a bit of thought. You could add an OnKeyListener() to your EditText. However, this listener only receives some key events. For example, if a user enters 'wyw', the predictive text will likely recommend 'eye'. Until the user chooses either 'wyw' or 'eye', your OnKeyListener will not receive a key event. Some may prefer this solution, but I found it frust. I wanted every key event, so I had the choice of filtering or not filtering. The solution is a TextWatcher. Simply create and add a TextWatcher to the EditText, and pass the ListAdapter Filter a filter request every time the text changes. Remember to remove the TextWatcher in OnDestroy() Here is the final solution: In iOS, there is a very easy and powerful facility to animate the addition and removal of UITableView rows, here's a clip from a youtube video showing the default animation. Note how the surrounding rows collapse onto the deleted row. This animation helps
  users keep track of what changed in a list and where in the list they were looking at when the data changed.

Since I've been developing on Android I've found no equivalent facility to animate individual rows in a TableView. Calling notifyDataSetChanged() on my Adapter causes the ListView to immediately update its content with new information. I'd like to show a simple animation of a new row pushing in or sliding out when the data changes, but I can't find any documented way to do this. It looks like LayoutAnimationController might hold a key to getting this to work, but when I set a LayoutAnimationController on my ListView (similar to ApiDemo's LayoutAnimation2) and remove elements from my adapter after the list has displayed, the elements disappear immediately instead of getting animated out.
