Android: Issue with newView and bindView in custom SimpleCursorAdapter

荒凉一梦 提交于 2019-11-27 11:30:13
I created a custom SimpleCursorAdapter from one of the only example I found . When my ListActivity is called, newView and bindView are called for every of my DB entry, and called again for every entry. I've got a few questions: -is the example right (if not, where can I find one)? -if bindView call is always preceded by newView call, why doing the same in both functions? -why is the sequence newView-bindView called twice for every item? -why some CursorAdapter examples use getView instead of newView and bindView? Basically, how should SimpleCursorAdapter be used, and what's wrong with my code?

I'm brand new to Android development... coming from iPhone and .Net background. I've seen very similar questions to this one, but none of them dealt with the SimpleCursorAdapter. I have a basic ListActivity which uses a Cursor to bind data from a SQLite query to my ListView: ListAdapter adapter = new SimpleCursorAdapter( this, android.R.layout.simple_list_item_1, c, new String[] {"name"}, new int[] {android.R.id.text1}); setListAdapter(adapter); Then when an item is clicked: public void onListItemClick(ListView l, View v, int position, long id) { super.onListItemClick(l, v, position, id); /

SimpleCursorAdapter deprecated in API version 15?

SimpleCursorAdapter deprecates one of its constructors with the following comment: Deprecated. This option is discouraged, as it results in Cursor queries being performed on the application's UI thread and thus can cause poor responsiveness or even Application Not Responding errors. As an alternative, use android.app.LoaderManager with a android.content.CursorLoader. Does this make the whole class deprecated? The other (standard) constructor is not deprecated. Only the constructor is deprecated, not the whole class. SimpleCursorAdapter (Context context, int layout, Cursor c, String[] from, int

I'm sorry if this looks like the same question a million times...but a google search for this provides no results, just a bunch of outdated tutorials using managedQuery and other deprecated solutions... I went through the android developer training for retrieving a contact list , but the tutorial is incomplete and even downloading the sample code doesn't help because the sample code is for more advanced contact list manipulation (search, etc.) In any case, there is no reason why there should not be a simple solution to this so I'm hoping someone can answer here because I'm sure this has been

How to insert extra elements into a SimpleCursorAdapter or Cursor for a Spinner?

时光总嘲笑我的痴心妄想 提交于 2019-11-27 04:13:30
问题 I have a Spinner which is to show a list of data fetched from database. The data is returned to a cursor from query, and the cursor gets passed to spinner's SimpleCursorAdapter. It is working fine as such, but I want to insert another item on top of this data. For example, the spinner is already showing a list of user created templates saved in DB, but I want to insert "New Template" and "Empty Template" on top of the list of templates, and it needs to be inserted into Cursor
