You shouldn't use Handler. When using CursorAdapter with db integration best thing to do is to implements LoaderCallbacks<Cursor> which will give you callback on every database changes. you will need to initiate the callback on your onCreate method like this: getLoaderManager().initLoader(0, null, this); Now the fun part: when implementing LoaderCallbacks<Cursor>...

How to implement an endless CursorAdapter?
android,android-listview,cursor,android-cursoradapter,android-cursor
In the comments pskink suggests to use AbstractWindowedCursor. I was not familiar with this class and investigated it a bit. It turns out that SQLiteCursor extends it already.

ArrayList is not working properly in CursorAdapter
java,android,sqlite,arraylist,android-cursoradapter
It's not a good idea to fill that array in bindView method. The Android doesn't create separate view for each row in the list, it's utilize already created ones, that's why you will always receive unexpected results in your arraylist. The better is to fill the array in your activity,...

Problems with setting two layoutsType at CursorAdapter
android,android-cursoradapter,android-viewholder
Your adapter must implement getViewTypeCount() (and return 2 in your case) and also implement getItemViewType(). Default implementation got no idea about your data and won't try to figure this out. It will just handle the case where there is only one view type used (hence the 0 returned). Add missing...

CursorAdapter.swapCursor not refreshing the first time
android,android-listview,android-cursoradapter,android-cursorloader
You're having this problem because ListActivity automatically sets the empty view (if available) to your ListView. I'd suggest you try one of these: Extend activity and after swapCursor call listView.setEmptyView(findViewById(android.R.id.empty); Make the empty view gone: android:visibility="gone" and after swapCursor call findViewById(android.R.id.empty).setVisibility(View.VISIBLE); @onCreate call listView.setEmptyView(null) and after swapCursor call listView.setEmptyView(findViewById(android.R.id.empty); Not...

Implementing own Android CursorAdapter for search suggestions - unknown exceptions
java,android,sqlite,searchview,android-cursoradapter
you have over-complicated this: there is no need for setOnQueryTextListener, just call: myCursorAdapter.setFilterQueryProvider(this); searchView.setSuggestionsAdapter(myCursorAdapter); in onCreateOptionsMenu, you will need your Activity to implement FilterQueryProvider where in its runQuery you return your Cursor with suggestions...
cursor is deactivated prior to calling this method
android,simplecursoradapter,android-cursoradapter,android-cursor
Apparently because of some issues in the code, the onLoadFinished() callback was called twice at almost the same time, which probably didn't have a good impact on the data Cursor. So double check your code if you encounter this issue.

Is it safe to have the same item appearing twice in a ListView backed by a CursorAdapter?
android,android-listview,android-sqlite,android-cursoradapter
The short answer...sorta. The slightly longer but still quick answer...so long as you aren't using a ListViews choice mode...you'll be fine. CursorAdapters derive their id for a given item based on the "_id" column. AFAIK, this is pretty much only used when determining which item is checked or activated. The...
