Android :: Add A Data Column To Contacts Db
Aug 6, 2009
Can I add a column of data to the Contacts db, such as birthday, favorite color, whatever. Or does the platform/ framework make this difficult? If possible, would I do it through the contacts content provider?

I read that the different entries in different tables are linked via the _ID column in that table. For example a contact might have an _ID = 1 I get via
ContactsContract.Contacts._ID
And now I want to read the phone number of that contact using
CODE:.............
This works fine, but what I would expect is that if the _ID of the contact is 1 that the _ID of the phone number is as well one since they belong together, but they are not equal. So the question is how does Android match these entries?

I'm working on an Android App where the user has different options for sorting the displayed data that comes from the database. Currently my orderBy string that I pass to Androids query() method looks like this:
"LOWER("+columnName+") ASC"
The problem with this is that if the data type in the column specified by columnName is integer, calling LOWER() on it will cause it to be sorted alphabetically, i.e. based only on the leftmost digit, which of course doesn't make any sense for numeric data. Hence I only want to apply LOWER() if the data type of the column is not integer. What I have in mind is a statement like this:
"CASE WHEN [data type of columnName is integer] THEN "+columnName+" ASC ELSE LOWER("+columName+") ASC END"
The part in the brackets is what I don't know how to do. Does SQLite provide a function to determine a column's data type?

I have two files, one called "part1.txt" and another one called "part2.txt", which look like following
part1.txt part2.txt
lili like eating apple
lucy like playing football
Now i want to insert the contents of these two files into a single table with the schema
table_name(linefrompart1 varchar(100), linefrompart2 varchar(50))
My program reads the first file line by line and insert the data into the first column. But if it reads the second file and tries to insert the data line by line into the second column, it doesn't work the way i want. A table which i want should look like following
linefrompart1 linefrompart2
lili like eating apple
lucy like playing football
But instead i got the following table
linefrompart1 linefrompart2
lili null
lucy null
null like eating apple
null like playing football
Does somebody know how i can fix this problem?

This has got me all confused! I'm trying to return the max value from a column in my database but the return value is always the name of the column.
The query I use:
private static final String SELECTMAX = "SELECT MAX(?) FROM " + TABLE_NAME ;
The (test) function to return the max value:
CODE:............
The column i'm querying is an INTEGER type but the result 's' is always the column name and not the desired value.

I am developing an application in android allowing the user to maintain his weight by providing him diet suggestions. I have done with that part and now, I need to display user weight tracking details using bar graph. I am able to fetch the Weight and Login date column data from the sqlite database to List<String>. I don't understand the way to put these values into a Bar Graph with Date Column data as X-axis and Weight column data as Y-axis.

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...

Does someone know how to get a 'flat' map / list of the contacts and there phone numbers. I am currently using this to build a datastructure, so I can display it in a lIstView, which is not really fast. The code shows that I do two queries. Would it be possible to do this with one query so that I end up with a just one cursor. The structure ideally would be: contact name number number contact name number
This would then allow me with a custom listView Adapter to display the data and make the names non clickable.................

I'm trying to add a custom data field and MIME type to the Contacts screen. Is there a way to do this such that when a user views a contact with my data saved on it, my field appears there? This is something I've seen other apps do--how do the Facebook, Twitter, Last.fm, etc. apps add their status information to contacts, for example? I can't seem to figure it out from the Contacts API documentation.

I want to design a table whose first column items remain fixed when user scrolls horizontally, but should scroll when the user scrolls vertically. Similarly the first row items remain fixed when user scrolls vertically, but should scroll when the user scrolls horizontally. Can this be achieved using a TableLayout? Or is there any other combination of widgets that I could use?

One of my android apps performs the following specific SQLite query:
CODE:................
Now that works on some Android phones, but on a few of them it crashes with the following error:
CODE:..................
For some reason, "-1" is interpreted as a column rather than a number... that doesn't make much sense and when I read the SQLite query language I see no need to escape this number in parentheses. Could it be an issue of a different version of SQLite? Would adding parentheses this help any? Instead, I'll probably rewrite it using >= 0 but still I'd like to understand what's going on.

I'm having trouble with something that works in the Notepad example.
Here's the code from the NotepadCodeLab/Notepadv1Solution:
CODE:.................
This code seems to work fine. But just to be clear, I ran the adb utility and run sqlite3 I inspected the schema as follows:
CODE:...............
All seems good to me.
Now on to My App, which as far as I can see is basically the same with a few minor changes. I've simplified and simplified my code, but the problem persists.
CODE:..............
When I run my app, I get a RuntimeException and the following prints in LogCat from my Log.e() statement:
LogCat Message: java.lang.IllegalArgumentException: column '_id' does not exist
So, back to sqlite3 to see what's different about my schema:
CODE:.................
I don't see how I'm missing the '_id'.
Can anyone point out what I've done wrong?
One thing that's different between my app and the Notepad example is that I started by creating my application from scratch using the Eclipse wizard while the sample app comes already put together. Is
there some sort of environmental change I need to make for a new app to use a sqlite database?

I'm not big into UI programming so this may be an easy thing I overlooked. I am trying have a screen that shows 8 TextView in a 2 column x 4 row table. And, of course, I want the TextViews, that might have different lengths, to be centered. I tried this in a table layout, for obvious reasons but I feel like this is not the way to do it because it doesn't have much control where I put everything once it is in a row. Should I be using a different combinations of layouts or is there something I overlooked.

This is an incredibly dumb question. So, apologies. But I can't find the answer anywhere and it's driving me nuts.
In DDMS, I have lost the tag column, i.e. the first part of the message from Log.d(tag, message). I can see time, log type, process id, and message - but not tag!
Anyone know how to get it back? I've tried right-clicking the columns, looking through the menus, etc - no joy.

I'd like to have column headings in a TableLayout and I'd like those headings to remain visible when the table is scrolled vertically. One option is to create a separate TableLayout just for the column headings but it's a little complicated keeping the column widths consistent between the two tables.

I am curious if there is a way to bind more then one db column to a resource. I need to bind more information to R.id.secondLine then just the difficulty column. But I'm unsure how to go about this? I'm currently subclassing SimpleCursorAdapter. Should I subclass another adapter?
If so How to do I go about it?

I have a TableLayout on one Android Activity UI. It has two columns. Now I need to add a new row, and put an EditText box in second column of that new row. And also, I want that EditText full fill the whole cell. I have some code like this:
CODE:..........................
It puts the EditText in the second column fine, but the EditText is too small. I tried to use etText.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); but that seems to disabled the TableRow.LayoutParams setting. I guess each control can only have one LayoutParamas setting. So, how to make the EditText as a 4 lines text editor and also make sure it is in the second column of that row?

I have a TableLayout with three columns that represents a form with
requiredSymbol | label | inputfield.
I want the input field to fill the remaining width of the screen right to the label. So far the only solution I found is this
CODE:....................
The maxWidth needs to be there are some value, which is actually ignored. Then the stretchColumns value does its thing nicely. Note that this also works if the content of the EditText would otherwise make the table span beyond the screen border (imho a bug..).
This works nicely now but seems a little bit of a hack to me. Is there a better way?
