Android :: Should Cursors Used In Autocomplete Adapters Be Managed Or Not?

Feb 10, 2009

I'm using an autocomplete box, with suggestions provided by a SimpleQueryAdapter.Not sure if relevant, but only difference I see is that, both in the adapter constructor, as well as in runQuery(), I use a cursor returned by SQLiteDatabase#query obtained via an SQLiteOpenHelper instance.Should I be using on these cursors or not?If I don't use managed cursors, then I get "leak found" warnings ("database was created [sic] but never closed").

Android :: Scrolling Large Lists Of Cursor-based Adapters Is Faster Than Much Smaller Lists Of In-memory Adapters

Nov 3, 2010

I have an Android app that has both CursorAdapter based ListViews (backed by sqlite) as well as custom BaseAdapter based ListViews which are built on the fly from JSON pulled down from a server.

The data displayed in both is identical - an image and a couple of TextViews. My Cursor-based ListView has 3000 rows, the JSON-based ListView has about 30. However, scrolling down the list is significantly faster for the Cursor-based adapter. For the JSON-based lists, the data is all fetched before the rows are made visible. Images for both types of lists are downloaded on-demand.

I have both ListViews configured identically - both with fastScrollEnabled, scrollingCache and smoothScrollbar set to true.

I'm looking for leads on how to go about trying to figure out what's going on here and to potentially fix it so that the JSON-based ListViews as as fast as the Cursor-based ones.

Android :: Do Cursors Provide Write Access?

Mar 16, 2010

"This interface provides random read-write access to the result set returned by a database query." but I can't find any way to update a database with a cursor.I have started noting things like this as a sidewiki entry for the documentation page.

Android :: ListView For XML Data - Existing Array Or Database Cursors

Android :: Views - ListViews And Adapters

Apr 20, 2009

Just looking at options for data updating affecting items in a ListView and have hit a few issues/queries.

There seems to only be notifyDataSetChanged() and notifyDataSetInvalidated(). While I could use notifyDataSetChanged() I am most likely in my case to have the scenario where additional data has been added and it seems inefficient to say the data has changed, which can only be resolved by calling getCount() and then getView() for all displayed items where knowing the data has been appended would just require adjusting the scrollbar. Is there some way to achieve something similar to this as the market seems happy populating dynamically in a manner that seems to reflect my desired behaviour (unless it just refreshes it all that fast).

Next question is the situation where the data behind just one item has changed. For instance I may wish to download icons in a background thread, but display available information with a placeholder icon. The best idea I've had so far is to store a map of indexes and views in my adapter which I can check against then call getView directly myself to have the view recycled with the new data. I'd just need additional logic to handle removing the map when the view gets destroyed or when it's recycled in getView. Either a bi-directional map (do we have one of those?) or two maps. Is the above likely to be my best approach or is there something built-in/better to get it done.

Android :: How To Handle Multiple Adapters For One ListView?

Jul 6, 2009

Currently I'm trying to find an efficient way to handle the following scenario. Please comment on my current implementations and all feedback is greatly appreciated! I have about 7 adapters with data. This data comes from database and some come from xml queries over the internet which are kept static in memory. In my current implementation I re-use one ListView constantly to display this data as requested by the user. Here are the questions: 1. Is this a proper approach? or should I have a ListView for every Adapter?

Android :: Combination Of Multiple Values In Managed Query

May 20, 2010

I've got a database. In its "tags" column, rows can have a combination of multiple values "A, B, C"--such that: row 1 has "A" row 2 has "A, C" row 3 has "B, A" and so on, in various permutations. I am trying to implement search using a managedQuery such that I can return a cursor that contains rows with one or more values in the query. For example, if the user enters "C, A" for a search, s/he should get all rows that have A, C, or A and C. I'm splitting the user query on the comma (",") character, and the final call is as follows (parameters replaced by actual values):

mActivity.managedQuery("content_uri", [id, title, tags], "title LIKE ? OR tags LIKE ?", [%A% OR %C%, %A% OR %C%], "title ASC")

Even though there are rows in the database that contain A, C, or A and C--the managedQuery returns nothing. Thankfully, if the query is for "A", or for "C", the appropriate rows with "A" or "C" or "A and C" are returned. It's just that a query with more than one search term returns nothing. What am I doing wrong here? My guess is that %A% OR %C% is incorrect logic, but why?

Android :: RAC Traffic Application - Managed To Use Alternate Route

Oct 18, 2010

I'd just like to sing the praises of the RAC Traffic app. It's bloody useful, especially for those who have a commute along the British motorways. Last week, I set off towards the M40 in Warwickshire and hit a bit of traffic. Unusual for 7:35am along that route. The traffic started building up and I started to panic in-case I was late for work. So, I got the Wildfire out, loaded the RAC Traffic app and had a look. 90 minute delays on the M40 Southbound. As I was going North, I stayed in the traffic jam. Needless to say, where the roundabout was that split the North and South traffic there was absolutely no traffic going my way.

Extremely useful as I stopped panicking and just listened to Last FM (via Bluetooth). It happened again this weekend, too! We were going on a trip (around 45 minute drive) and we hit traffic. Got the phone out, looked at the traffic, and managed to use an alternate route through the residential areas using my SatNav. I'd strongly recommend this application to anyone who has to do a bit of driving/has a lengthy commute.

HTC Tattoo :: Managed To Get Photoshop App

Feb 12, 2010

Has anyone managed to get the photoshop app on their tattoo yet?I have been looking and it still is not in android market on the tattoo. I looked on the adobe site to see I could download it from the website onto my computer as I have done for some other apps that are not in the market. Not there they just direct to the android market.I then found the adobe android app forum and asked about it saying that I wanted it for the tattoo. I had a reply that it is compatible with tattoo and that I should get it from the android market. I replied to that saying that it was not there and could they get it put in.No response yet and it has been a week. I will try again soon but just wondered if anyone had found somewhere else to get it?

General :: Managed To Uninstall Play Store

Jul 9, 2012

Yesterday after turning on wi-fi on my EVO 3D, there was a system update notification. Yes, it was the long awaited ICS. Since it was very late I didnt play around it with it till today. When i did, i noticed that play store wont update my apps anymore due to 921 error. Quick google search suggested that i delete cache and reinstall app. Well, i managed to remove the app somehow (even though i got "was not removed successfully message"), because whenever I press the Play Store icon, the message "the linked program is no longer installed on your phone" appears. I have no clue how to get this back. To be honest i dont understand how a user can be allowed to remove such a vital app...

Android :: How To Disable Autocomplete On AutoCompleteTextView

Dec 5, 2009

So this is a response to another thread, that I never got a reaction on. Hopefully someone can give a hand. I have a AutoCompleteTextView with a CursorAdapter with data. I need to be able to set a text in the AutoCompleteTextView programmatically without the autocomplete mechanism kicking in. If I use *setText *on the AutoCompleteTextView it will start the autocomplete. I tried calling *dismissDropDown() after setText, but this dosnt work because the drop down is not shown yet.

HTC Hero :: Managed To Get 3G Data Working For Weather Email However Browser Does Not Work

Dec 2, 2009

I just bought a Telus HTC Hero, which the seller had unlocked. I intend to use this phone with another carrier, Bell. After spending a few hours at Bell customer service, they finally managed to get the 3G data working (for weather, email etc.). However, the browser does not work, neither does the Market.

What seems to be causing the problem is that this phone is MASSIVELY tweaked (appears massive to me probably because I'm not that big on tweaking and don't know about the Android OS in general) by the previous owner who only had it for a few days. The Bell customer service person told me that they switched over a couple of other HTC devices from Telus that were NOT tweaked and the data works perfectly.

All I want is for the phone to be in original factory settings, with original ROMs, firmwares, software, etc. etc. Just looking at the whole bunch of different files that this guy had on the 2GB "gold" memory card made my head spin. He attempted to explain to me with all the "updates" and fancy "roms" and "roots" and crap that I didn't understand nor do I want to spend the time to learn.

I understand that a lot of people buy android phones because they love tweaking but I am not really into all that... I just wanted the phone for the form factor and the functionality and I don't want to worry about optimizing and whatnot. So my question is: is there any way to get the phone back to the most original possible software condition? I just want it "clean." Can I go ahead and wipe everything that is on the 2 GB card? What do I do? I performed a hard reset and it took me to some weird startup screen and I chose the first option which is like reboot now (there were also a bunch of other options including apply update.zip or something)... it still gave me the same MoDaCo build.

I can provide any information but I would really appreciate any help in restoring my seemingly very tweaked phone to original, factory settings, so it could be like any other phone being sold by Telus other than the fact that it is unlocked.

Android :: Autocomplete List From SQLite With Criteria

Jul 3, 2010

Can someone point me to right direction, how to create an adapter for AutoCompleteTextView, which would be getting data from SQLite DB, using data, which user entered into the text field? I want to use the user-entered data to filter suggestions for autocompletion.I imagine that adapter should always take user-entered data as soon as changes appears and use it for fetching suggestions on-the-fly. Is that possible? So far I've seen many tutorials for autocompletion where static String arrays were used, but never seen them build dynamically.Is it possible to do it automatically or I need always fetch String array myself and pass as ArrayList to adapter on every AutoCompleteTextView change?

Android :: Search Suggestions / Autocomplete OnClick Behavior

Mar 17, 2010

I cannot seem to dictate the behavior of the onClick function.When a suggestion is clicked, it fires off the intent immediately. Is there a way for it to instead of firing off the intent immediately,simply copy and paste the suggestion as part of the search string?Eg. when typing in J,o,h the suggestion "John" comes up. When I click "John" can it copy that text into the search bar instead of immediately processing the search with John?I'm assuming theres a simple configuration which I cant seem to find.I dont want to go extensively into catching the fired of intent and re-processing etc

Android :: Sorting Results When Autocomplete Matches Multiple Columns In SQL

Oct 27, 2009

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?
