android-cursoradapter

I'm stumped as to what is causing this error, as I have made sure that I am closing my database adapter properly (at least I think I am). Here's what LogCat's saying (the tag for all of them is AndroidRuntime): FATAL EXCEPTION: main java.lang.IllegalStateException: database /data/data/com.acedit.assignamo/databases/data.db (conn# 0) already closed at android.database.sqlite.SQLiteDatabase.verifyDbIsOpen(SQLiteDatabase.java:2082) at android.database.sqlite.SQLiteDatabase.lock(SQLiteDatabase.java:413) at android.database.sqlite.SQLiteDatabase.lock(SQLiteDatabase.java:400) at android.database

I want to fill my ListView with data that's going to come from the web in the form of JSON. The list should be theoretically infinite, with the app making requests for more data if scrolled to the bottom. Should I use a Cursor or an Array(List) adapter to link my online database with my ListView ? More generally, what are the arguments to consider when choosing between cursor and array ? Well I think you should look at ContentProviders . They are more natural to the problem that you are trying to solve. You have to implement your custom Cursor which ContentProvider returns on a query request.

i'm using CursorAdapter for reading database in listview. i have a checkbox in the each item of the list that when the checkbox was checked by user the favorite Column in my database change the yes and the item added to the favorite. everything is ok and the favorite column changed but when i scroll up and down the list the checkbox going to unchecked. and if you restarting the app the checkbox have been checked what should i do for this problem: sorry for my bad english: CursorAdapter class: public class MyAdapter extends CursorAdapter { Context b; LayoutInflater inflater; @SuppressWarnings(

I have been suffering this issue for months and months (but now I am performance tuning). However, I now desperately need to know why my adapter feels it is necessary to run bindView up to 4 times on a record. I have a custom cursor adapter that populates a gridview. Some debug to show what's going on: 03-08 14:46:47.980: I/AdapterCursorGrid(20724): newView() 03-08 14:46:48.470: I/AdapterCursorGrid(20724): bindView() 03-08 14:46:48.570: I/AdapterCursorGrid(20724): -------------------------- 03-08 14:46:48.570: I/AdapterCursorGrid(20724): bindView() Record Id: 1 03-08 14:46:48.570: I

I know that this question is probably asked a hundred times so far, but i still haven't manage to solve my problem. I have one activity that's comprised of 2 fragments. One fragment is a form that adds information to the database: **R.layout.fragment_add_server:** <?xml version="1.0" encoding="utf-8"?> ... <LinearLayout android:id="@+id/nameLinear" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_marginBottom="5dp" android:layout_marginLeft="5dp" > <TextView android:id="@+id/nameText" android:layout_width="fill_parent" android:layout_height="wrap_content"

I have a ListFragment , where I add a CursorAdapter to my ListView , and I want to be able to click several rows, to use contextual action bar. I use SherlockActionbar, and it works fine, when I use a simple ArrayAdapter . But when I switch to CursorAdapter , it breaks. I cannot select multiple rows, only one. Any idea why it might happen? In onActivityCreated I set up the list: @Override public void onActivityCreated(Bundle savedInstanceState) { super.onCreate(savedInstanceState); mActionMode = null; mListView = getListView(); FinTracDatabase database = mDatabaseProvider.get(); Cursor cursor

I'm learning about custom providers and loaders. As a simple example I'm trying to implement a GridView that shows the pictures stored in the external SD card. Although I've read a lot (documentation, threads on SO, Google groups, forums...) I'm not able to get my code working. I know that several issues may be present on this example but I want to go step by step. The first error stopping the code is a NullPointerException , so my question is how to fix it. This is a minimal version of my Activity (it uses support library v4): public class MainActivity extends FragmentActivity implements

I am working on a app , in which i require to populate list view from the database. I am getting compatibility issue in following code dataAdapter = new SimpleCursorAdapter( this, R.layout.eventlisting, cursor, columns, to, 0); It requires min api level 11 , mine is 8. Is there any alternative for this to make this code work on api 8 as well. Can i use support library? Try the SimpleCursorAdapter from the support class . It is used like the API 11+ version and it is already backwards compatible. You have to download the Support Library , so you only need to change the import Like This way :

I am getting this question due to another answer on here, but didn't explain how to do what I am asking How to get the id of the row in onItemClick(ListView) when using a custom Adapter? The answer which was accepted in that question is what I need since I am also making my own custom adapter (CursorAdapter), hence I will have the same problem. The problem is I have no idea how to accomplish that. I am looking at the Doc, and am not sure how to access the _id column from a cursor. Since the Doc doesn't have the constant which we can get that info from I'm stuck. Any help figuring it out would
