Android :: Inserting Data Into Cursor?

Jun 23, 2009

I'm looking for a way to insert data into a cursor that is separate from the SQL database it retrieves the rest of the information from. Is there any way to to this, or is there a different way to add more information to a list view item? What I'm trying to do is to use a date column for each entry in the list to calculate the number of days until that date (and then put that number in the list item). I know how to get the value, but I just cant find a way to put it into the list without it being in the cursor.

Android :: Data Not Inserting In Sqlite Database

Aug 14, 2010

I am an android application developer. I am developing an application which requires of me to use Sqlite database. I have implemented fetching the data, but i am facing problems when i try to insert data into the Sqlite database. The problem that i am having is that the new data i enter is not fetched, i.e nothing is new is being entered into the database.

this is the method i wrote in Data.java
myDataBase is an object of SQLiteDatabase
public void insertTitle(String Recipe)
ContentValues initialValues = new ContentValues();
initialValues.put(COLUMN_NAME,value);
myDataBase.insert(ZRECIPE, null, initialValues);
}
and i create an object "d" of it in Add.java, where i call the "insertTitle()" method. But nothing is inserted.

Android :: Inserting Large Volumes Of Data Into SQLite

Sep 2, 2009

I need to insert approximately one million rows of data (spread over 4 tables) - each row has one or two numeric fields, and two or three text fields (normally quite short). Single-column indexes on all the fields. After doing some tests on the emulator with a small test set, I extrapolated (assuming the last row will be inserted with a similar speed to the first row) my results to figure out that this would take about 15 hours (I have a Core 2 Duo running Vista). However, then I tried running the small test set on my Hero and I was surprised to see it run more than four times faster. I would guess it would take about 3 hours on the Hero. Alternatively, I could make the pre-populated database available as a download on the first run but this is likely to be a 120MB download. I have a few questions I'm hoping someone can help me with: 1. SQLite performance on the actual device being 4-5 times faster compared to the emulator - is this normal/expected? 2. Do the figures above generally sound fast/slow/normal (sorry this is so vague)? 3. From a user perspective - would it be best to provide a 120MB download or a 3 hour "first-time initialisation" step (plus 6MB download)?

Android :: Show Cursor Data In A Listview With Subsection Headings

Feb 3, 2010

I have not found an example yet with a solution to the following task.

I have a SQLite database with two tables- BOOK and AUTHOR. I execute a query on the DB that uses a join and results in a cursor that looks like this. code...

New authors and books can be added to the database at any time, and I also need the user to be able to remove books, hence the [ ] checkboxes.

So i have two row layouts, row_author.xml & row_book.xml. I detect when I need to show a row_author subheading by seeing when the current author has changed compared to the previous row. But I have realized that the rendering of an Author Row will then move the cursor forward one row and jump over their first book.

Can anyone suggest a good approach to presenting data like this? Is there a much better way to do this?

Android :: Proper Implementation Of Changing ListView Data With Cursor Adapter

Sep 3, 2010

I have a ListView populated via a CursorAdapter. I give my user the ability to alter the data in the list. For example, the user can mark a row as being unread (the data are messages).

Suppose my user marked a row unread. Would a proper implementation mark the row in the database as read and then requery the Cursor?

Android :: Moving Cursor Adapter Cursor Creation To Background Thread

Mar 29, 2010

The structure of some of my activities is a simple ListView with a custom CursorAdapter. The cursor is created in onCreate() on the activity from a SQLite database. The problem is that querying the SQLite database can be quite slow at times with lots of data (and let's assume I've already optimized the sql query as much as possible). Because it occurs in onCreate() on the UI thread, I get ugly black screens when opening the activity, which sometimes turn into ANRs, on a slow phone like the G1. I want to load the cursor in a background and show "Loading.." on screen while doing so. I saw AsyncQueryHandler used extensively in the framework, but this seems a solution geared more towards Content Providers and not application-local SQLite databases. I then thought of trying to load the cursor in a background thread, but realize that this might be problematic, as the CursorAdapter should be instantiated in onCreate() and should take a cursor as a parameter. The latest thought I had was to instantiate an empty MatrixCursor in onCreate() and pass that to the cursor adapter, while kicking off a thread/TimerTask to query the database. Then, on database cursor load, call cursorAdapter.change Cursor to the properly filled cursor. This doesn't seem very elegant and seems quite wasteful, however.

Android :: Join ContentResolver Cursor With A Database Cursor

Mar 21, 2010

I 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?

Android : Adding A "column" - Data To A Database Cursor

Maybe I'm going about this the wrong way, but if so, please correct me. Here is the situation: I have a query which returns URI strings for ringtones stored in a database.

I am trying to add a "column" to this cursor with the ringer "Title" (since this can change outside my program). I can successfully user RingtoneManager to get the title, but I cannot figure out how to add this "column" to the cursor data for later use. Here is what I have so far: Code...

Android :: New Inserting Contact Not Working / What To Do?

Aug 28, 2009

I am trying to insert a new contact, but, even though I get a valid URI back, the Contacts do not appear in the "Contacts" application.

Code...

My problem lies already in the first three lines. The contact does not seem to be stored. However, consecutive runs of this show, that the internal ID is increased nonetheless.

Is there something I am missing? Do you have to "commit" the changes?

Android :: Inserting Image Into Predeveloped SQLite DB

Aug 11, 2010

Ive developed a DB for use with my app but I've realised that I actually want extend my db to incorporate images! I will be hosting the db online but for now I am using it locally for development purposes. To create my db I have been using SQLiteBrowser, which I think is a standalone version of the Firefox SQLiteManager plugin, however I cant see a way to insert an image. I recognise that an image will have to be transfered into a byte array and stored as a blob, but rather that developing this element of the db programatically, I was wondering if the was a gui tool to help me skip this developmental element.

Android :: SQLite And Inserting Current Date In UTC Format

Nov 24, 2010

How do I use an SQL statement on an sqllite database to insert the current date in UTC. I found the NOW function but what format is that in? This will be on mobile devices so everyone will have a different locale, however, I need a standard time format because the device will compare the dates with my server. Also, is there a way to automatically update a 'modified' field when the data in the row is changed like you can in MySQL?

How do you do that? - i.e. insert the status-bar within ones own 'full- screen' View?

Android :: SQLite - Inserting String With New Lines Into Database From Csv File

Sep 9, 2010

I am trying to inject a long text entry into a SQLite database, in a TEXT field. This text has new lines in it (i.e. it spans multiple paragraphs). I can get the new lines to show up if I do the INSERT manually:

INSERT INTO "LOGENTRY" VALUES(5,40,'PLACE','line1
line2
line4
',1283990533315,'4A','TEXT','',NULL);

but if I have the equivalent text in a CSV file and attempt to .import it into the table, I get an error that it's expecting more columns than exist (as soon as the new line is encountered, the program assumes it's the end of the input and thus it's missing columns). Is this possible? Or is the only way to manually do each INSERT?
