simplecursoradapter

问题 I have a simple contentProvider, a layout with a ListView and a button for adding Items in content Provider and a CursorLoader. The http://developer.android.com/reference/android/app/LoaderManager.LoaderCallbacks.html#onLoadFinished(android.content.Loader, D) reference states that The Loader will monitor for changes to the data, and report them to you through new calls here. You should not monitor the data yourself. For example, if the data is a Cursor and you place it in a CursorAdapter, use

问题 I have a Listview that I want to populate with information from my SQLite database with and this seemed like the most practical solution. In my debugger it says it's caused by: IllegalArgumentException No such column. Id does not exist This is the java file I'm trying to populate it with: data = new MyData(this); ListView lv = (ListView) findViewById(R.id.list); ListAdapter adapter = new SimpleCursorAdapter( this, R.layout.list, data.selectData(), new String[] { "name", "title" }, new int[] {

问题 Tell me please, why it doesn't like my layout (RelativeLayout with @+id/row )? When I use it with self created adapter (layoutinflater) it works good. And one more. I plan to use in my database bitmaps, stored like byte[] . Can SimpleCursorAdapter itself convert byte[] dates in to image (ImageView) or does it work only with texts? Error description android.content.res.Resources$NotFoundException: Resource ID #0x7f0c006c type #0x12 is not valid MainActivity protected void onCreate(Bundle

问题 Hey i use a listview for demonstrate entries which are stored in a database. I also have a EditText element and a button which adds the content of the EditText into the Database. To bind the view to the database content i use the SimpleCursorAdapter and following populate function: private void populate() { cursor = dbAdapter.getAllItems(); startManagingCursor(cursor); String[] from = new String[] { DBAdapter.KEY_TASK }; int[] to = new int[] { android.R.id.text1 }; // Now create an array

问题 I have a weird problem with listview, while using simplecursor adapter. Here is the error 08-31 21:50:14.540: INFO/dalvikvm(12195): Uncaught exception thrown by finalizer (will be discarded): 08-31 21:50:14.540: INFO/dalvikvm(12195): java.lang.IllegalStateException: Binder has been finalized! 08-31 21:50:14.540: INFO/dalvikvm(12195): at android.os.BinderProxy.transact(Native Method) 08-31 21:50:14.540: INFO/dalvikvm(12195): at android.database.BulkCursorProxy.close(BulkCursorNative.java:289)

问题 I'm setting up my app so that people can create groups of their friends. When a group is created, it writes 2 tables to the SQL database. The first table has a group name and a group id. The second table has 2 columns, a group id and a user id. This is working fine. However, now I want to be able to read from the database. I'm using a listview fragment with a cursorloader but I'm having trouble getting the information to display. I want to list all the group names from the first table in my

问题 Currently there is no default implementation of RecyclerView.Adapter available. May be with the official release, Google will add it. Since there is no support for CursorAdapter with the RecyclerView currently, how can we use a RecyclerView with a database ? Any suggestions ? 回答1: If you are running a query with a CursorLoader and you want RecyclerView instead of ListView . You can try my CursorRecyclerViewAdapter : CursorAdapter in RecyclerView 回答2: My solution was to hold a CursorAdapter

问题 I'm building a ListView with either TextView s or ImageView s based on whether or not the item is a text item or has an image associated with it. I used Customizing list shown from SimpleCursorAdapter using VewBinder and it worked great, up to a point. I have an SQLite database containing items that all have a title (some text), but not all of them have an image/video as a resource; so some are pure text items while others are images or videos. For the images and videos I want to load a

问题 I have extended SimpleCursorAdapter and am running into a weird issue with bindView, which appears to be called twice on the first row. Only the first row appears to be duplicated. I have a feeling it has something to do with the way the cursor is positioned, but have looked through all the adapter classes and can't seem to locate where this occurs. Here is my code for bindView, I have inserted some Logs to show what I'm seeing. @Override public void bindView(View view, Context context,

问题 SOLVED IN A COMMENT: Adding onListItemLick/onItemLongClick in a ListFragment The problem was generated from an ImageButton in the layout of the single element in the ListFragment that was stealing the input even with the focusable element set to false, so i had to remove it from the layout. I've got a ListFragment populated by an extended class of SimpleCursorAdapter (mainly for overriding the newView method) but I wanted to add an AlertDialog when the user presses (or long presses) an item
