Android :: Populating Spinner From SQLite Database

Feb 3, 2010

I'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:


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.

I am trying to populate a spinner depending on another spinner's selected item, my code is the following:


what is intriguing me is that the first spinner onitemselection works perfectly ( I can see the values in LogCat) then when I change selection of the 2nd spinner I am gettging an error on this line: String selected= (String) s2.getSelectedItem(); So the compiler gets insisde then onItemSelected function of the 2nd spinner but throws an Handler exceltion on s2.getSelectedItem()

why? it works perfectly for the 1st spinner.

I'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?

Android :: Database - XML Or SQLite?

Mar 25, 2010

I'm doing a application that will use a database with serialized object. The objects will be already serialized and the user will just display things. On a PC I would just make an XML but with android I'm not sure. Can I make an XML and "unpack" it when the user launch the application for the first time or should I do something else?

Android :: Use Own Sqlite Database?

Mar 5, 2010

I put my database field in "assets" folder. And use the code from this blog to copy the database to "/data/data/my_packname/databases/", (This copy code i run it in the onCreate() method when i run this app) then use select * from ... to get data. But it gives me the exception: no such table. Someone told me that if i am attempting to copy the file in SQLiteOpenHelper's onCreate(), it's too late. So the copy file code can not copy the complete file. So i need to use adb or ddms to pull the database first? So, Anyone can teach me how to use my own databse?

Android :: Delete Top Row In SQlITE Database

Aug 2, 2010

public void delete(String id, String name, String phonenumber, String time, String message)
String[] args={id};
getWritableDatabase().delete("texts", "_ID=?", args);

It works fine, and deletes the specified row. However, I also want to implement it so that I can delete the most recent (earliest date) entry in the database, which should be at the top of the table. I know I can do this by altering the last 2 parameters of delete, but I cannot figure out what to change them to.

Android :: Necessary To Close SQLite Database?

Jul 22, 2010

Is it really necessary to close an SQLite database that your activity has opened (database is in local memory or on SD card)? I would think it would be good practice, but I noticed that the Android samples such as the Notepad tutorial and SearchableDictionary sample do not do this. I've also seen sample code where the database is consistently opened, read from, and closed, but that would seem to add unnecessary overhead.

I use a sqlite database in my project. The stored data in it must not be available for the user to edit. As I've read here I saw that if you have root access you can alter sqlite database. The only solution would be to encrypt database content, but this would be time consuming for device. Any solution to prevent access to database ?

Android :: SQLite Database Slow Insertion

Aug 17, 2010

I need to parse a fairly large XML file (varying between about a hundred kilobytes and several hundred kilobytes), which I'm doing using Xml#parse(String, ContentHandler). I'm currently testing this with a 152KB file.During parsing, I also insert the data in an SQLite database using calls similar to the following: getWritableDatabase().insert(TABLE_NAME, "_id", values). All of this together takes about 80 seconds for the 152KB test file (which comes down to inserting roughly 200 rows).When I comment out all insert statements (but leave in everything else, such as creating ContentValues etc.) the same file takes only 23 seconds.Is it normal for the database operations to have such a big overhead? Can I do anything about that?
