Android :: Retrieving Records From A Created Database And Put It In Spinner
Jun 18, 2009
I created a database with records in it and everything. I am trying to use its fields and put it in a spinner. The database contains university names.
I created a spinner with:
CODE:............
where I am feeding the spinner the records from an array. I want to do it from the database that I created. I read thru the classes and there are 2 ways but I can't find a proper code to use any of them. I just want to insert the code to get records from the database. It shouldn't be complicated is it?

I am trying to fetch sms messages from inbox, sent items and drafts. I would like to do a pagination for my list view for that it's imperative that I fetch records in pages/chunks.
I am not familiar with sqlite which is the database I understand android use to store the data. Can someone tell me how can I restrict the number of records I am fetching by using contentResolver.query?
Also what is the way to pull the sqlite database file onto my machine and browse/query it locally to experiment or see data on my machine?
Are there any other better ways to implement pagination in android?

is it possible to extract (and read records) SQLite Database out of Android application/.apk file/...)? Because I have some important information in it, so I wanna be sure it's pretty secure (only application has access to it)?

I created the following method for retrieving stored settings from the database:
public String getEntry(long rowIndex){
String value = "";
Cursor c = db.query(DATABASE_TABLE, new String[] {KEY_NAME, VALUE}, KEY_NAME + "=" + rowIndex, null, null, null, null);
int columnIndex = c.getColumnIndex(VALUE);
int rowsCount = c.getCount();
if(rowsCount > 0){
String value = c.getString(columnIndex);
}
return value;
}
On debugging I can see cursor c contains two columns and one row but when it comes to line
String value = c.getString(columnIndex);
it throws the CursorIndexOutOfBoundsException although columnIndex = 1 which should point to a valid entry. Does anyone know what could be wrong here?

I've just started working with SQL and Android and from what I can see, updates and inserts back to the database need to be handled individually?
I can retrieve a Cursor containing multiple records, but if I wanted to apply an update to each record in the cursor, I can only see how to do this individually, using ContentValues and Update(), and then the cursor requires reloading??
Same with if I wish to create multiple new records, these appear to be required to be inserted individually? Can I not create a List and bulk insert?
To me this seems slow and cumbersome, and there has to be something I'm not yet aware of (searching for answers is failing me... likely due to using incorrect terms being new to android/java)
Here's a very simple example of what I basically what I want to achieve, however there must be a better way to achieve this functionality. (I know there are some other bad practises in here, just creating a quick eample)

In one android application, I created a database file in data/data/com.rams/databases/dbfilename.
If I created a second application with the same package name (com.rams) and I access the database file created with my first application, the second application is able to access the database contents.
How can I secure the database file created with my first application?

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:
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.

I have an minor issue when taking a photo. I have a button that invokes the camera, successfully takes a photo, and returns to my entry form. My only problem is the database leak that occurs when pressing the button to call the camera.
My code looks a little something like this.
code:..........
I run :
code:..........
In the onCreate of the Activity or Class that I am calling the camera in. I have not coded in mDbHelper.close(); anywhere not sure if i should when or where. I think i would rather just leave it open while capturing one image.
Logcat:

Everything seems to be working fine, but i would defiantly like to avoid any issues amongst the many android devices out there.

I'm thinking about creating an application that uses multiple databases. The user would be able to specify the name of the database to be created, and select which database to use from those existing in the /databases/ directory.

I use this code to generate a spinner in my app:
code:.........
On my device (Motorola Milestone) and in the emulator this looks like the standard gray spinner widget.
On of my colleagues uses a Motorola Backflip and on his device the Spinner is black. Now its very hard to read the font in the spinner.
What do I have to do to use my own view for the spinner? I don't mind to have the gray spinner on all devices, but it should always look the same on all devices.

I have a spinner 'aperture' set up with a list of numbers, and a spinner 'mode' with two options. When a button is pushed I need a calculation to run using various inputs, including the current selection from 'aperture' and a value derived from 'mode'. How do I call the value of a spinner so I can use it in a calculation?
Also, how do I use the spinner 'mode's selection to set this other value before implimenting it in the calculation? To be more specific, if the spinner is set to Small then the value I use in the calculation is 0.015, whereas if Large is selected I need to use 0.028
My other inputs are EditText views, so right now I am set up like this:
CODE:............
That is not the actual equation, it is just a test to make sure everything connects properly. How would I call the value of spinner 'aperture' and the Small/Large spinner 'mode'

I have a spinner widget in my activity which lets users pick a list name.
Normally, the function of the spinner is to switch between lists but for a couple of instances, I swap out the selection change listener to perform a different function with the same list of options. Once the selection has been made, the old listener is restored and life goes on.
This is a bad and buggy arrangement. Instead, I would like to have a function that just takes a selection listener and some other parameters and shows a popup list that's populated by the same cursor (or and identical cursor) as the spinner, without using the spinner itself.
Is there any way I can do this?

CODE:.................
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.
