View 3 Replies View RelatedI'm attempting to make a dynamic drop down that will be filled by a SQLite table. I have a Cursor object which I can pull the data I need from. I've been able to accomplish loading the values into the drop down with the code below:
CODE:..............
My problem is that I need the a selection from the drop down to also contain the RowID of the item selected. I need to be able to select one item and have access to the value of that item in the back end. For example, think of a drop down in HTML. Each drop down selection has it's own hidden value that is pulled. I need this value to be hidden for me to allow me to know which ID they choose.

View 3 Replies View RelatedI am having some trouble working with the SQLite database. I am able to create the database, add to it, and delete from it with no problem by following the Notepad examples, but I am trying to avoid duplicates and therefore want to check to see if an entry exists already.
Below is the code I have for testing to see if a game exists. I get the correct Log message of "No Games" when there are no games, as well as the correct value for column from getColumnIndex which is proven to me by the log printout telling me that column = 1.
The error message that I receive if I don't catch the exception says "Caused by android.database.CursorIndexOutOfBoundsException: Index -1 requested, with a size of 1
Where is Index -1 being requested if my call to getColumnIndex is returning 1? Code...

View 3 Replies View RelatedIs it possible to populate a listview based on a row Id from a custom cursor adapter. I keep getting an error "illegalArguementException column: _id does not exist". but the database has it and is already being used correctly. I don't know what to do, because I would need to populate different listviews from the same database and i don't want to have to create multiple database which will still have the same column names code...

View 1 Replies View RelatedI get records from the system by quering a ContentResolver. I maintain the order of the items in the database. So I want to display the items in the order taken from my database.
How do I merge these two informations?
I am looking after an alternative way now. As what I ideally want is:
Get order of contacts by a custom order held in my database (this involves joining CR with my DB cursor, and doing an order by, later seams it's not possible with CursorJoiner) but there is more, if the join is not unique I want to sort by contact's name as last measure
Which is impossible using Cursor and Joiners, because of the missing feature of order bys, also I need to return a Cursor, as I will be using the in an ExpandableList
Also this translated to TSQL it would look like
select * from contactsdata
left join category on contactsdata.catid=category.id
order by category.pos asc, contact.display_name asc
So I am looking now after an alternative. I have in mind to load in a temporary DB table all data from CR, then do the query on the temporary table where I can join tables and do order bys? How does this sound to you?
Is it possible to take a csv file stored in the res/raw resource directory and use it to populate a table in the sqlite3 database? My thought was that, if there was a way to do a bulk import for the entire file into the table then that would be cleaner and faster than iterating over each line in the file and executing individual insert statements...
but I'm having trouble applying those statements in my Android application. My first thought was to try something like the following...but no luck:
db.execSQL("CREATE TABLE " + TABLE_NAME + "(id INTEGER PRIMARY KEY, name TEXT)");
db.execSQL(".mode csv");
db.execSQL(".import res/raw/MyFile.csv " + TABLE_NAME);...............
I successfully binded a spinner widget to a simple cursor adapter, but I started having problems when I tried to add a new item to the table which feeds the spinner by clicking an "add new item" button. The idea was to launch a new activity which returns the rowid of the just added element, and use it to set the new position.
What I basically did is to implement something like:
break; in the "onActivityResult" method, the rowid has the correct value but setSelection has no effect. I also tried to force the argument to some other values, but still with no result. If I call it in the onCreate method, it works beautifully. Moreover, I am still not sure that setSelection is the right method to call, since its arg is named "position" in the doc, while I am passing an "id".
I have a .sqlite file with one table in it. i want to access this data. Please tell me, where to copy this .sqlite file (in eclipse project) and how to access the data from this .sqlite file.
please suggest some code or liniks.. [i am using Android 2.1, dont know the database version..]
In my activity, I have an AutoCompleteTextView that gets its contents from my custom adapter. I created my adapter by following this example.The adapter works so far, but I am getting so many errors on leaks and cursors that are not finalized.My question is: how do I close the db in runQueryOnBackgroundThread?

View 2 Replies View RelatedI'm currently developing a Field-Service application that stores data in the local sqlite database on an android device. At some point, usually after completing the data collection rounds, the local sqlite db is to be synchronized to a remote sybase db on the server.Any suggestions as to how this could be achieved or engineered as a solution? Or even better, are there alternatives to synchronizing data in such an application?

And i can't open my database.
I've got a query, (I'm using rawQuery())
SELECT * FROM <table>
I'm then storing what it returns using a cursor. From their what I want to do is, start at the first row so.. cursor.moveToFirst() then take each column , column by column and store its particular value in a variable. I then want to move onto the next row and do the same. So I guess my question is How would I get cursor to deal with multiple columns?
How can i access the contact and account manager with the help of sqlite3 code? can u please explain me about contact application?
View 2 Replies View RelatedThe following function is giving me an out of bounds exception...
public void count(){
SQLiteDatabase db = table.getWritableDatabase();
String count = "SELECT count(*) FROM table";
Cursor mcursor = db.rawQuery(count, null);
int icount = mcursor.getInt(0);
System.out.println("NUMBER IN DB: " + icount);}
It's meant to return the number of rows in the database. Anybody know whats wrong? am I perhaps doing this task the wrong way?
In the API Demo, there is example on using Simple Cursor Adapter. However, it is using the MediaS tore cursor. Is there any method so that I can use other external cursor prepare by SQL database. I don't know what should I input to the from String.

I been using custom adapters based on the BaseAdapter and I usually populate my data at the getView() funtion.
Now I'm trying to write my custom adapter for my database cursor which now will be based on a CursorAdapter.
I'm getting confused where I should do the populating work? Along with how do I implement my inflating and populating "smart/efficient code based on RomainGuy presentation."

So I wanted to know if it was possible to "import" my own SQLite database (not created with my App but with a 3rd-party software) to my project, and if the answer is yes, where should I save my SQLite databse and how can I have access to it.
