Hi. Can someone please tell me how can I easily display every record from sqllite in ListActivity tab? I'm kinda confused with this. Do I have to create db from my helper class in TabActivity or ListActivity or both? My db helper class is as follow,,.

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.my_list);
mDbHelper = new MyDbAdapter(this);
mDbHelper.open();
fillData();
registerForContextMenu(getListView());....................
The date is actually stored as an int in the SQLLite database, and thus it displays as an integer. Does anyone know a way to create a date from the int so it doesn't display as 1216544611 (or whatever) but as "12/11/2009 11:32"?
I want to know how can I get the number of records (rows) in a specific table in my db. I need this so I can create a loop to go through every record and add each one of it to the specific Array and display it later on.
This is the source:

I have a 800 kb xml file on a server. I download it, and parse with a SAXParser.
And then i add all item elements to my SQLLite db on the phone.
All item has 50-60 element.
One insert query take about:
11-18 21:15:54.079: ERROR/448 delay_(9169): 41207
11-18 21:15:54.099: ERROR/448 delay__(9169): __ 41223
about 20-90ms , i have 500 row, and it takes 40 minutes, it is a good value for this?
How i can do it faster? Is it possible?
What's the easiest way to populate a SQLLite table with data off a URL?
I'm writing a Delphi web app that will generate a file on a server for my Android app to download.
In Delphi, I'll probably save it as a .csv file and use bulk import to import into MS SQL Server.
What's the easiest / best practice way to do this in Android? How would I download the file from the URL and then load it into SQLLite?
I'm kinda new to android programming so please bear with me. I'm having some problems with retrieving records from the db. Basically, all I want to do is to store latitudes and longitudes which GPS positioning functions outputs and display them in a list using ListActivity on different tab later on. This is how the code for my DBAdapter helper class looks like:
public class DBAdapter
{
public static final String KEY_ROWID = "_id";
public static final String KEY_LATITUDE = "latitude";
public static final String KEY_LONGITUDE = "longitude";
private static final String TAG = "DBAdapter";....................
I would like to store an object into a SQLlite database. I am looking for how to best do it in order to ensure that if I need to updata/change this object in the future that users of the new and old object layout will be minimally impacted. In other words I want to ensure that making changes to the object will have minimum affect on clients that do not update their software on the old database format.
I want to also ensure an easy update from the old record style to the new format. I was thinking that I could add an element in the SQL row to identify the object type with a unique name, and to identify the object version number. That way I could read the row and use the object number to control the deserializer to use the correct version of the class.
Has anyone got an example of how to write a ContentProvider that gets its data from somewhere other than a SQLLite database? Mine is half working, in so much as I can retrieve the requested data and apparently populate a MatrixCursor, but I can't figure out what I'm supposed to do with the 'projections' parameter supplied to the 'query()' method.

View 4 Replies View RelatedI'm a .NET developer starting to dig into an android application. One thing that seems a little abstract is working with SqlLite. In a .NET application, I can do my Database setup, query testing and profiling, and enter in some test records through Management Studio for MSSQL. In fact, I'm constantly in Management Studio checking something - so I'm finding it difficult to work without a similar tool.
What are some good tools/tricks to use when developing SQLLite on Android? The tool doesn't have to have a GUI, but would be nice if I could run it as a desktop app and have it look at the same DB as my emulator.
For instance, something that will allow me to run a simple SELECT statement against a table to view records without having to do it through android?

View 2 Replies View RelatedIs 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 am trying to populate a ViewStub with a new view depending on which ImageButton is clicked, but as I just discovered ViewStubs I am not exactly sure how this would work...

How can I populate a menu using intents? I didn't understand that thing.
Or is there any better way for that?
Update:
Suppose I have an application that need to resize the image,and there are many other applications that have a capability of resizing the image. How can I show the list of applications on a menu in my application so that when clicking on a particular option it will invoke the intent associated with that application. Simply saying I could resize the image in my application with out bothering about how that will get done.
Is it possible to populate an activity menu at startup? For example, reading from say a feature database at startup and only display those features that are currently active in an activity menu?
