android-loadermanager

I have a ContentProvider , it's having two tables 1. OnlineContacts 2. AllContacts . Then i have a method in which i am querying both the tables and getting their resultant cursors separately. And then joining them using CursorJoiner and making a list of Contacts . Passing this list to my CustomAdapter extending BaseAdapter , i am populating my listview . Like : public static List<Contact> getContacts(Context context){ List<Contact> contactList = new ArrayList<Contact>(); // Getting First Cursor String URL = xyz; Uri baseUri1 = Uri.parse(URL); String[] select = xyz; String where =xyz; Cursor

I want to make my ExpandableListActivity compatible with Honeycomb. I am wondering why there is no ExpandableListFragment for the Compatibility Package. Is there a way to make ExpandableListView work with the normal Fragment class? How do I load the Cursors with the LoaderManager? I had the same problem. I didnt find a solution for this, so I decided to implement the ExpandableListFragment myself based on a combination of the android.support.v4.app.ListFragment (Compatibility API) and the android.app.ExpandableListActivity from API level 8, so this should be compatible with API level < 11. I

I have searched the numerous questions that look like this one, but haven't found my answer in any of them. I have an activity that has 3 tabs accessible through the action bar. I achieved this by adding 3 fragments that inflate a custom view I made extending the view class. At the moment the database changes, I try to refresh the view in my tab by calling invalidate()/postinvalidate(), but this does not work. The same is true for calling onCreateView of the fragment just as many other options I considered. When I go to another tab and go back, however, the change has been made and my view is

Trying to update my old app in which some methods are deprecated. I found out that if I want to work with ListView that shows data from db, I should use LoaderManager + CursorLoader. CursorLoader works with content providers. So for every table in my db I should create content provider now ? Why should I ? As far as I know content providers is used to share some db information with other applications, but my app dont share any information. So can I use CursorLoader without content providers ???

I'm completely lost regarding the differences between the initLoader and the restartLoader functions of the LoaderManager : They both have the same signature. restartLoader also creates a loader, if it does not exist ("Starts a new or restarts an existing Loader in this manager"). Is there some relation between the two methods? Does calling restartLoader always call initLoader ? Can I call restartLoader without having to call initLoader ? Is it save to call initLoader twice to refresh the data? When should I use one of the two and (important!) why? Emanuel Moecklin To answer this question you

I am using compatibility package for implementing CursorLoader in API level < 11 As per the doc and this answer and this wonderful tutorial , I have imported the support packages and implemented the LoaderManager.LoaderCallbacks , but next I have to call: getSupportLoaderManager() and for that one has to extend FragmentActivity, and then call from Activity Context, but I have already extended ListActivity, and want to make a static call to get LoaderManager, like this: FragmentActivity.getSupportLoaderManager() Apparently, this is a way to get LoaderManager < 11, that's what the doc says: To
