Hi guys. I've made a ton of attempts at getting a contentloader to work. I am
trying the following code, but am getting the exception listed below it. Any
help for this floundering person is greatly appreciated. The exception appears
to be database related, but I don't grok the meaning. Code: [Activity(Label =
"Content Loader Example", MainLauncher = true, Icon = "@drawable/icon")]
public class Activity1 : ListActivity, LoaderManager.ILoaderCallbacks
{
// This is the Adapter being used to display the list's data.
SimpleCursorAdapter mAdapter; static String[]
CONTACTS_SUMMARY_PROJECTION = new String[] {
Android.Provider.ContactsContract.Contacts.InterfaceConsts.Id,
Android.Provider.ContactsContract.ContactsColumns.PhotoId,
Android.Provider.ContactsContract.ContactsColumns.LookupKey,
Android.Provider.ContactsContract.ContactsColumns.DisplayName,
Android.Provider.ContactsContract.ContactStatusColumns.ContactStatus,
Android.Provider.ContactsContract.StatusColumns.Status,
Android.Provider.ContactsContract.StatusColumns.Presence,
}; protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle); // Set our view from the "main"
layout resource
//SetContentView(Resource.Layout.Main); mAdapter = new
SimpleCursorAdapter(this,
Android.Resource.Layout.SimpleListItem2, null,
new String[] {
Android.Provider.ContactsContract.ContactsColumns.DisplayName,
Android.Provider.ContactsContract.ContactStatusColumns.ContactStatus },
new int[] { Android.Resource.Id.Text1,
Android.Resource.Id.Text2 }, 0);
ListAdapter = mAdapter; // Get our button from the
layout resource,
// and attach an event to it
LoaderManager.InitLoader(0, bundle, this); } Loader
LoaderManager.ILoaderCallbacks.OnCreateLoader(int id, Bundle args)
{
// This is called when a new Loader needs to be created. This
// sample only has one Loader, so we don't care about the ID.
// First, pick the base URI to use depending on whether we are
// currently filtering.
Android.Net.Uri baseUri;
baseUri = Contacts.ContentUri; // Now create and return
a CursorLoader that will take care of
// creating a Cursor for the data being displayed.
String selectWhere = "((" +
ContactsContract.ContactsColumns.DisplayName + " NOTNULL) AND ("
+ ContactsContract.ContactsColumns.HasPhoneNumber + "=1)
AND ("
+ ContactsContract.ContactsColumns.DisplayName + " != ''
))";
return new CursorLoader(this, baseUri,
CONTACTS_SUMMARY_PROJECTION, selectWhere, null,
ContactsContract.ContactsColumns.DisplayName + " COLLATE
LOCALIZED ASC");
}
public void OnLoadFinished(Loader loader, Java.Lang.Object data)
{
// Swap the new cursor in. (The framework will take care of
closing the
// old cursor once we return.)
var d = (Android.Database.ICursor)data;
mAdapter.SwapCursor(d);
} public void OnLoaderReset(Loader loader)
{
// This is called when the last Cursor provided to onLoadFinished()
// above is about to be closed. We need to make sure we are no
// longer using it.
mAdapter.SwapCursor(null);
}
}
