Mar 22, 2010i have the following problem. I fill a ListView with a custom ArrayAdapter with data from a BD. However, in background, i'm updating those datas from the info provided by an API, so the idea is when the update finish, the adapter shows the updated data instead its "old version".
The problem is that when i do that, i notice a lag while the adapter is updating itself. Is the any efficient solution to avoid this?

View 1 Replies View RelatedAndroid :: Populating A Listadapter?
Feb 18, 2009I've built an application that loads XML from a server, then creates a list of items and with that I create and adapter that I set with setListAdapter(my adapter);
The problem I'm having now is that creating the list and adapter takes time, so I was thinking on creating just like 20 entries and populate the list, then create the rest on runs background or maybe when the person gets to the bottom (like gmail application).
Android :: ListView And ListAdapter
May 25, 2010I am trying to use ListView and ListAdapter. If I create a simple Android project and add a ListView as the content view, and set it's adapter to my adapter based on ListAdapter, everything seems to work. My ListAdapter's 'getCount' is called, and I return 3, my 'getViewTypeCount' is called and I return 1, my 'getItemType' is called and I return 0, and for each item, my 'getView' is called and I return a TextView. Everything works, and the list is displayed with 3 items.
Now if I try and do the same thing in a more complicated environment, it does not work. My 'getCount', 'getViewTypeCount' and 'getItemType' methods are called, but the 'getView' method is never called and the ListView appears empty.
Now I know that I must be doing something wrong in the more complicated case, but I cannot see what it is. The code is really too involved to post here, but I was hoping that someone could give me some ideas as to why my 'getView' is never called even though I return 3 from my 'getCount' method.

View 1 Replies View RelatedAndroid :: Bind Data To ListView Without Preparing ArrayLists For ListAdapter?
Sep 14, 2010I get my Models in a nice object-oriented form. In order to bind them to my List, I have to use the listAdapter. Can I only fill this listAdapter with stupid ArrayLists? Because that means, I have to iterate over my ModelCollection and pull all the data out of my Models again. So, I detach my data from the models and I cant easily refresh the data in my listView, if something chances in the modelCollection (like becoming bigger through new Items / pagination). Does a more intelligent way exist, than I use right now? Can I bind my ModelCollection more driectly to the listView?
ModelCollection modelCollection = ModelCategory.findAll();
/*
* Prepare Data for Adapter
*/
ArrayList<String> itemTitles = new ArrayList<String>();
// Iterate over my ModelCollection and pull all the Data from each Model
for (int i = 0; i < modelCollection.items.size(); i++) {....................

Android :: Java.lang.ClassCastException When Using Self-defined ListAdapter In Listview
Mar 11, 2010I am writing a adapter for a specific app, the problem I met is:
I have only 1 listview in main.xml, and the row style is defined in file_row.xml. If I simply use list.setAdapter(new ArrayAdapter<String>(this, R.layout.file_row, R.id.file_name, items)); where items is a ArrayList<String>, everything works well.
But if I use my custom Adapter, say, list.setAdapter(new MyOwnListAdapter(this, filename)); and in the class of MyOwnListAdapter, the code has been simplified as
CODE:................
But I always met the problem which is:
CODE:.........
I thought the self-defined Adapter class actually has only one line of valid execution, which is super(context, R.layout.file_row, R.id.file_name, filename_list); It's essentially identical to direct calling of list.setAdapter(new ArrayAdapter<String>(this, R.layout.file_row, R.id.file_name, items)); Then why I always got this error if I call my own Adapter?

Android :: Loading A Large List Of Contacts Into A ListAdapter - Making It Responsive
Jan 23, 2009I need to load Contacts.Phones.CONTENT_URI and Contacts.ContactMethods.CONTENT_EMAIL_URI into a ListActivity.
Since these are separate Content URIs, I have two separate cursors and can't construct a SimpleCursorAdapter for use in the ListActivity.
The problem is that I have more than a thousand records for CONTENT_EMAIL_URI, which were automatically loaded by GMail. The app becomes unresponsive and Android prompts to kill the app or wait.
Is there a way to make the ListActivity content load in the background, like, by writing a custom implementation of android.widget.Adapter?
Or is it more feasible to use a single cursor, by manually running the SQL query on the contacts tables?

View 2 Replies View RelatedAndroid :: Notify Activities Of Download Completion?
Aug 12, 2010My application has an IntentService which runs periodically to download data from a remote server. The download task is run inside an AsyncTask which has reference to Application context only. The data downloaded is for entire application and is displayed across four different activities. When the download completes(AsyncTask completes) the service is notified of the same. Now, the service needs to notify appropriate activity to update its view. The service is not aware of which Activity of what application is in foreground.
How do I make that connection? How does the service pass a message to the activity in foreground that new data is available and it should update its views?
