Android :: Sorting ListView ?
Apr 14, 2010
I'm only starting with Android dev, and while the Milestone is a nice device Java is not my natural language and I'm struggling with both the Google docs on Android SDK, Eclipse and Java itself. Anyway...
I'm writing a microblog client for Android to go along with my Windows client (MahTweets). At the moment I've got Tweets coming and going without fail, the problem is with the UI.
The initial call will order items correctly (as in highest to lowest)
3
2
1
When a refresh is made
3
2
1
6
5
4
After the tweets are processed, I'm calling adapter.notifyDataSetChanged();
Initially I thought that getItem() on the Adapter needed to be sorted (and the code below is what I ended up with), but I'm still not having any luck.
CODE:.....................................
Is there a better way to go about sorting ListViews in Android, while still being able to use the LayoutInflater? (rowLayout = t.GetParent().GetUI(t, parent, c) expands the UI to the specific view which the microblog implementation can provide)

I was very confused when I looked at the list of my contacts the first ftime after syncing them to the Desire. Only then I realized: this thing is sorting first names first! I find this most annoying and unusual. And worse: I found no setting, yet, that would allow me to choose the sorting.

I want to create multiple handlers that gets triggered based on users selection, but this handlers implement the same runnable method. the only difference is that they call different postDelayed() method. how do i go about achieving this without rewriting the same code for the runnable? i am still not clear about how the handleMessages() works and if it can be used for this?

all text messages appear to sort by thread (in other words by sender). can the droid sort by the date and time they came in? just a list of all text messages without a filter?

Does anyone else wish that the Android Market had sort options? I know when I browse the Market, I can filter by paid apps vs free apps. That's part-way there... I also want to be able to sort by rating/ranking (# of stars), number of times downloaded, cost, and so on. Also, carry these sort options over to the Search. It's even worse as you have paid and free apps mixed together.

I am sorting my database depending on date. The date field in SQLite is nothing but a string, stored in the form of dd-mm-yyyy. How do i carry out the sorting.
My idea is to create a dummy table.Convert the date in a format yyyymmdd. Then sort it simply using sort by date column.Then again drop the table.

I'm looking for a detailed App for sorting and categorizing all of my contacts. I have 700 phone numbers, and am a junior in college, so needless to say, sometimes it's nice to only see female phone numbers. Also, if there is one where you could sort people by key words like soccer, school, parties, etc. Also, with the Verizon network, is there anyway to send texts to more than ten people at once? Is there anything like that out there available for my droid? Is there a way to sort/edit my contacts on my computer? I feel like it would be much easier.

I've updated (uploaded a new version) of my app, TimeTracker, twice in the past couple of months, and in both cases, the new upload has not shown up in the "by date" sorted list of the Market app. When I search for the app, I see the correct version in the Market, and I can find it in the correct category by scrolling down; it is just that the updates aren't being correctly sorted.

One of the task of we are working on is to enable the Android Contact sorting by stroke for LOCALE zh_TW. It's very easy to enable the contact sorting by Pinyin for zh_CN, but when I take the same method to enable sorting stroke for zh_TW, the sorting result is either sorted by UNICODDE or PinYin. It's very strange. I have investigated the related code located in android_pkgs/external/icu4c/xxx and tried many options but failed to find a wayout. Is there anybody familiar with icu4c or have ever done some work on this topic? Here I'd like to append the steps (mainly on the location android_pkgs/external/icu4c/) I did as reference:
a. append zh_TW into product locales;
b. append the zh_TW support into icu4c/stubdata/Android.mk
c. taking the cfg-us as example, create a folder cfg-us-zh and append zh_xx related 'zh_xxx.res' files;
d. ./helper.sh us-zh will generate a updated icudt38l-us-zh.dat;
e. recompile Android to launch emulator -EOM-

I implement ProviderTestCase2 to test my content provider functions. And when I insert huge number (about 10000) of data, the insert, delete and update functions are fine. But the query function will have SQLiteDiskIOOException: disk I/O error. And the data number limit of causing the exception is about 5000. Is it bug of content provider?
And there is another problem. Each of my data has different priority. When I sort my data by priority, its no problem. But when I change priority of some data and then sorting again. Sometimes I will get incorrect result and I'm sure its not logical problem of test program.

Is it possible to actually re-sort an Android SQL DB? for example, I want to resort the Bookmarks DB. I can query the data and sort it with "Browser.BookmarkColumns.TITLE + " ASC" in the query but this will only sort the list shown to the user and will not sort the DB itself. Therefore, if a user uses my app to sort the Bookmarks by Title(ASC) and then goes to the Android Browser Bookmarks - the order will remain default (other than the one selected on my app).

I've run into an issue with an autocomplete field I'm working on.The field I'm working with is composed of the form "<NAME> (<CODE>)".When a user starts typing in text, I want to display any results that match either NAME or CODE.For example, if this list contains items and their codes, like "Personal Computer (PC)", then I'd want the list to pop up that row if the user types "P", "PC", "Per", etc.However, the problem I'm running into now is how to best sort the results that come back from this.For example, If someone enters "PC", I want "Personal Computer (PC)" to be the first result. However, if there's another row (you'll have to bear with me as this is contrived) "PC Case (301)", then there's no simple ordering I can do on the results to ensure that the best match appears first. Ordering by name and code both returns PC Case first.I want a query where it returns the best match first, rather than items in alphabetical order.Is there such a function I can use in SQLite to get this, or should I return the results and then mess with the order in the code?

I am having a weird issue. I have an ArrayAdapter which I am sorting. This displays properly on my screen, however when I check the actual data source, the contents have not been sorted. How can I ensure that sorting my ListAdapter will also sort my data source?
CODE:....
This shows that my data source hasn't been updated, even though my ListAdapter presents my ListView in the correctly sorted order.
For example:
If my data source is [10,9,1,20] after sorting my ListView will show [1,9,10,20] but the data source will still be [10,9,1,20]

On the Nexus One and I guess non-SenseUI, I could change how my contacts were sorted, "last, first" or "first last". On the EVO, I can't seem to do that. But on Favorites in the 9x grid, it sorts them "first last".

Just updated both EVO's to Froyo and I'm aghast. I still can't sort contacts Lastname, Firstname. This is such basic functionality that is missing from this phone.

I am coming from the iPhone camp and got the Captivate to replace my old iPhone 3g. So i am used to, and spoiled by the mindless simplicity of using it. I have spent all most all day, every day since monday, when I got this thing trying to get it to work how I want it to work. The phone came with a HORRIBLE "user guide" that was 5 pages long and show you really only how to put the battery in, and make a simple call. The 140pg PDF one i found on line was still of little help, and samsung support is just rediculous. It seems pretty crappy to me to expect the user to have to do so much second hand research to use their product.
1. Kies is garbage, I havent been able to get it to work. When it finally did detect the phone, it said it need a new driver and it has been at "installing driver 0%" for 3 days, I tried double twist, which is really quirky, but finally got music on my phone, but had to create playlists via the phone as it ignored the ones I made in doubletwist... During the syncing, the phone would randomly connect/disconnect over and over and over, finally it went thru.. Is there any better way to get music on the phone...............

I've figured out how to make seperate folders to sort my pictures. Ive got folders like:
Pets
Friends
Food & Drink (yes i take pics of my food lol)
Landscapes
etc, etc...
For this I just made a folder on the root of my sd card and named it "pictures" and in THAT I put all my sub folders, and the gallery detects them all just fine. Today, I finally got around to organizing the pics in each folder. Like the ones in pets, I have pics of my dog, cats seperate, cats together, kittens when they were born, bearded dragon, etc, which were just all in the order I took them. To organize them better I decided to rename them... so I did:..............

I have multiple ArrayLists built from parsed XML that are directly related to each other in order. The arrays are later put into a single mapped ArrayList (groupData) to be read with a SimpleAdapter which creates the list in the Android GUI.
What I want to do is sort the list in alphabetical order based on one array (arr_title) and the other arrays stay in synchronized order to it. It doesn't matter where the sorting happens as long as the final displayed list is sorted. I expect it would be best to sort the mapped array once it's built. The simpler or easier to understand the code the better, but don't want the sorting to go very slow either. I have about 140 objects per array, but that could expand considering the XML is pulled from the web.
I've spent hours searching Google and tried a number of things with little progress. Collections.sort(arr_title) will sort the one array as I want it, but then the other arrays don't match up and doing the same thing to the other arrays obviously just sorts them individually as I don't want. I've noticed mention of using the TreeMap type and Comparator for similar sorting, but couldn't figure out how to use them in this case probably because the examples didn't provide a big enough picture for me to understand.
The sample below is where most of the stuff happens after the separate arrays are created.
CODE:............
SimpleAdapter adapter = new SimpleAdapter(this, groupData, android.R.layout.simple_list_item_2, new String[] {"title", "desc", "num"}, new int[]{android.R.id.text1, android.R.id.text2});
setListAdapter(adapter);

The stock music player on ROM I am using (Virtuous 2.3) is, I assume, the latest out with the most recent OTA (8/26?).
I am having a beast of a time getting it to play well with the phone. I had a similar problem using Third Wave, but did not have this problem with FrankenROM.
I see ONE album art, it isn't even the first artist by track name, alphabet or anything else. I am not sure exactly how the phone decided on this particular piece of art. It is the same art for every track. My tracks are no longer broken down by artist either, like they once were. It is a huge folder called "Unknown Artist" that is literally filled with all of my tracks.
Previously, in 2.1, my songs were all sorted problem by Artist>Album>Song. Each tab worked properly as well, though I sorted by artist most times. All of my tracks are in the same folder on the internal storage (EMMC). I have never had an issue with it prior to Third Wave and now Virtuous.
I keep my music on the internal storage because I presently only have a 4gb SD card and feel that it is sufficient for what I do with the phone, especially considering that I've got 8 gigs built into the phone that I should be able to use. That is all beside the point.
I searched prior to making this post and didn't see anything else relevant to the issue that I am having. Is anyone else plagued by this or a similar issue? Is there a newer/better/different version of the HTC Music Player that might fix the issue?
I doubt this makes a difference, but I had this issue with both the Stock kernel and the Hydra kernel. I am currently on the stock kernel because I just installed a kernel patch for Virtuous 2.3.

I just switched from a Nokia N95 to an HTC Desire on Android 2.1 (Froyo isn't out in the Middle East yet I guess). I'm having a lot of trouble getting my contacts on to the Desire. On setting up the phone, it has pulled my contacts from Gmail & Facebook, which I don't really need. I will not be calling or mailing most of the people on that list. There are a 1000+ contacts on those lists and I don't need all of them on my contact list. I tried to use the Nokia Ovi Suite to sync contacts, but for some reason I was not able to transfer them onto the PC. So I copied them all onto the SIM card and then put the SIM into the Desire and exported them to the phone memory.
The problem is that on copying them onto the SIM on the N95, I have multiple entries on the list. For contacts with more than 1 number under them, there are separate entries for each number, with the same name. Is there a method to group them the same way they were earlier i.e. One contact entry with a Home, Mobile, & Business number? Do let me know. It will hugely helpful. The only other way I can think of is to sit and enter all the numbers manually!

I have the At&t N1 and set it up with my Exchange server. The biggest issue I've run into is that the phone seems to ignore my File As setting for the contacts. Some of them are sorted as "first last" and others are "last, first", even though in Outlook they're all the same. I've removed the account and set it back up again with the same result. Actually, after removing the account, the contacts didn't clear either, neither did the calendar.
I got the trial version of Touchdown, which eventually cleared the phone's contact list, but I could never get it to sync its contact database with the phone's. According to their FAQ there should be an option for it, but that never shows up for me. It doesn't really matter to me if I have to use Touchdown to accomplish this or not, but if I do, then I want it to sync to my phone's database because I like the Favorites tab

just added music/photos/videos to my 8gb microSD via an adaptor into my laptop. Sorted so that most recent photos are top but when I insert into the Wildfire it shows oldest photo first. Put the card back in the laptop and reversed the sort, put it back in the Wildfire but made no difference. Can't seem to find any sort options on the Wildfire unless.
