View 2 Replies View RelatedI want to read my cursor position so that, after a tap, I can convert the screen x,y coordinates to a Geopoint for distance calculations.I found a snippet to convert x,y coordinates to a Geopoint and probably could use Projection instead, but how do I input those screen x,y values in the first place? This is probably straightforward, but I'm confused.The class Cursor seems to be something different than what I need

View 4 Replies View Relatedcan anyone tell me what im doing wrong with my cursorAdapter? its making my display choppy when i scroll. I used to have it within a getview but was ripped (rightfully so) on IRC several times because thats not the right place for it. Im still learning and just trying to correctly wrap my head around things.

In my actual project I need to draw a MapView with a given running/walking/cycling path on top of it. I don't need the current position so I added an overlay just for the path (no MyLocationOverlay). The path is painted but I don't see the Map in the emulator - only the grey tiles. The apiKey is set in the layout (MapView) and INTERNET permission is set in the Manifest. So I'm wondering if I need more. Is it the emulator simply not working well (I do have 3G and 2 bars in the emulator) or do I need something else? Do I need to build an additional overlay or add additional permissions (xxxLOCATION) to the Manifest.
View 1 Replies View RelatedThe 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.
View 10 Replies View RelatedI 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?
On my htc i was looking through display, i see g sensor calibration and i perform this calibration and after i do so the screen seems to have a delay when switch from the horizontal position to the vertical position. its weird because when i switch to the phone horizontally it switch normally and responds fast. but when i switch back to vertically it takes almost 7 seconds to actually switch back, sometimes it switch within 2 or 3 secs but never as quick as switching horizontally.

If you're already updated, shut down and repower (soft reboot) should do the trick. I actually updated my phone and after it started to do this. I restarted the phone plenty of times i even took the battery out for 30 seconds. It only does it when im texting on the browser, basically everything but the camera. He camera screen rotation is perfect. I even rooted the phone but i havent figured out how to use the root to fix the problem. Should i do a firmware update? Because i just did the htc software update.
I am seeing the exception in 'adb logcat'.But I don't know if it is caused by my application or android platform.Can you please give me any idea how to troubleshoot this exception?

I am facing one problem in message view. Bacically what I need to do is in message view I want to mark any telephone number or web address in different color. Can anyone please tell me where exactly the text is been written in Message View? On clicking this items it should launch appropriate event. If anyone touches a telephone number it should launch the dialer or if it is a valid email address then it should launch the Compose message event and so on.
Another question is whether to display message is Android uses the WebView?
I am dispalying some data by using sqlite .when i click on one button data come from database. It takes some time. At that time the screen is black .At that time I want to display the rotating spinner before the data dispaly.

View 2 Replies View RelatedHello there I have a problem regarding the new HTC Magic I purchased : in my text display where I read the conversations between me and my contacts... it has all of the messages I sent in 1 group together, and all of the messages my contacts have sent together. How do I change this to display the order in which they were sent and received? For example right now it is
ME : blahblahblah
ME : blahblahblah
ME : blahblahblah
You : blahblahblah
You : blahblahblah
You : blahblahblah
I've got this piece of code where I count words in a dictionary and then I try to query them:
CODE:.............
The SELECT_BY_LENGTH is defined this way: private static final String SELECT_BY_LENGTH = "select word._id, word.word from word where length(word.word) between ? and ? ";
And the count works perfectly but the cursor.move(1) always returns false. I've tried to get the column count and responds with the correct count and the column names map too. I mean that the method getColumnIndex works too but I can't get any data from the cursor. All such methods fail. Am I doin' something wrong? I'm using android 1.5.
I call ContentResolver's query method to get a Cursor, and I would like to update the title of that row to 'new title' how to do it?

View 5 Replies View RelatedI have a Cursor points to a Contact. How can I get an url built from that Cursor?
I need to know that because from here: http://developer.android.com/guide/topics/providers/content-providers.html
I need to have an url so that I can build a phone uri, like this: phoneUri = Uri.withAppendedPath(uri, People.Phones.CONTENT_DIRECTORY);
and I can query all the phone numbers for that contact.
I have two tables I want to (inner) join, Contacts.People and Contacts.ContactMethods. The result will be displayed in a ListActivity. After looking into this, it appears that I should use CursorJoiner. So the code would look something like this: So my question is, how to I make a new cursor from the first two?
View 2 Replies View RelatedI have a query that is making use of GROUP BY so that the results are grouped by a date column. My question is this:
When I move through the cursor to get the results of the query, how can I get the multiple items associated with each group into my vector? For example, I want to get BOTH "Item X" and "Item Y" for October 16, 2010. Currently, I get them each separately.
Here is my code:
CODE:..........
So, when I get the results from my Vector, I will get:
October 12, 2010
- Item X
October 12, 2010
- Item Y
And I want:
October 12, 2010 - Item X, Item Y
Yes, I do have to change my Vector to support multiple items, but hopefully you get what issue I'm facing...
I have problems with Cursor in my Android application.
I have a SQLiteDatabase that return me Cursor when I try to fetch the values with :
code:.......
But I don't know how to obtain the value of the field in the Cursor.
If I do that :
code:........
I obtain the name of the columns (_id, title, body) but not the value.
I want to make a content provider for font file. But I can not find any way to return a Typeface from Cursor. According to SDK reference, Matrix Cursor sounds like a solution, but it doesn't support any object except String,Long,Double,Short,Flow.
