Getting item position from cursor adapter
java,android,eclipse,android-cursoradapter

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.

Implementing own Android CursorAdapter for search suggestions - unknown exceptions

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.

How to remove all but the checked item from a CursorLoader?
java,android,listview,android-sqlite,android-cursoradapter
I have solved the problem. What I did was adjust the bindView() method to store the id of a doctor when it is selected: public void bindView(View view, Context context, Cursor cursor) { ViewHolder viewHolder = (ViewHolder) view.getTag(); final long id = cursor.getLong(cursor.getColumnIndex(DoctorEntry._ID)); String firstName = cursor.getString(cursor.getColumnIndex(DoctorEntry.COLUMN_FIRSTNAME)); String lastName =...

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.

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...
Change row color of a ListView with Cursoradapter and bindView

SQlite primary key field name & CursorAdapter subclasses
android,sqlite,simplecursoradapter,android-cursoradapter
