View 7 RepliesI'm wondering if there's any way to merge two cursors together and then resort them.I can easily merge two cursors together by using a MergedCursor, but that doesn't sort them.I have two sets of contacts in two separate cursors (with totally different schemas) and I want to merge them and sort them by name (the name column is different in the two cursors).

View 5 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.

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?

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'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)

When a refresh is made

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.

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 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?

View 1 Replies View RelatedDoes 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'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.
View 12 Replies View RelatedOne 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).
View 11 Replies View RelatedI'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?

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".

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.

View 4 Replies View RelatedI 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);
