I need to create a list view that display same functionality as Contact App. I need to have a scroller through which i can traverse the list alphabetically. To achieve this i am following an example from API demos "com.example.android.apis.view.List1.java". When i implement this functionality on a static list view => it is working fine. But when i try this on a dynamic listview=> it is not working.

View 1 Replies View RelatedI added android:fastScrollEnabled="true" to the xml description of my listview class. I was (probably mistakenly) expecting this to magically transform the scrolling of my really huge listview so that the thumb button and the indexes display on the right side.
Is there more to hooking up the listview so that the framework knows what its alphabetizing? I have custom defined cells.
I've read lots of articles about intent filters and I really can't understand exactly what they do? so please if anybody can explain to me with a clear example what is the role of intent filters exactly ?

Is there any way out there to organize your apps menu other than by alphabetical order? When you have a heaps of different apps and are always trying new ones like me it's not always easy to find that one that has a name that relates nothing to its function.Ideally I'd like some way of making categories in my app menu and and grouping all my utility icons, all my game icons etc.

As the world cup is the main sport event and the Vuvuzelas are the most annoying sound in the world, I had an idea to remove them definitively by reading this new ( http://www.popsci.com/diy/article/2010-06/simple-software-can-filter-out-vuvuzela-whine) that told us that the sound has some frequencies at 233Hz + 466,932,1864Hz.
I have already made a lot of Android application by myself but never touching the signal analysis and filtering part, so here are a few questions, I do not ask for precise answer but maybe links and tutorial to find something to work on. I guess that a new Android phone has the CPU and power to make real-time filtering.
1) How can I intercept the sound coming from the Jack microphone - Line-IN plug- ( I plan to link my TV to my phone with Jack to Jack plug). My question is totally software and coding, I have all the wires and adapters to plug a jack into my android phone Line IN.
2) Are there some Fourier analysis librairies, may I have a look to Java libraries on the web and import them to my Android project?
I'm new in Java/Android programming, so please have patience with me.
I try to play a mp3 which is locate und the assets folder. I know there is another way with the /res/raw/ folder, but use the assets-folder because later I'll try to access the file by String.
This code works to play a mp3-file:
CODE:...............
Now the problem: In the same assets-folder is another mp3 file stored. Though I specify the name of the mp3 to use it take the one which comes first in alphabet. E.g. the other file is named "music.mp3" it plays this one. Renaming it to "worldmusic.mp3" it will play "song.mp3". Rerename "worldmusic.mp3" back to "music.mp3" it will take this mp3 again. Another test: Renaming "song.mp3" to something other so the application can find whats specify by the code above will result that no song is played. So this means the songname have to exist, although it take arbitrary the song first in alphabet.
I'm testing with the AVD emulator of eclipse. But I think the behaviour would be the same on a real device.
I want to set in project properties build target 2.2 (api level 8) In the manifest.xml <uses-sdk android:minSdkVersion="3" android:targetSdkVersion="4"/> is declared. Did anybody tried, if any user (with min. Android 1.5) see application in the market? Could some other problems occur because of different SDK for building and in manifest?!
View 2 Replies View RelatedIs there a way to know which Intent Filter is responsible for launching an Activity which has two Intent Filters defined in AndroidManifest.xml? I want a slightly different set of logic, but not enough that should require a whole new Activity.
View 1 Replies View RelatedI don't see anything about this change in the API differences report at http://developer.android.com/sdk/api_diff/8/changes.html. However when my Nexus One started running Android 2.2, the list of files created by the following code are now in reverse alphabetical order rather than alphabetical order (as they were with Android 2.1 and earlier, AFAIK):
CODE:.........
The line "Arrays.sort(fn);" revives the alphabetical order of the list, but sorts are computationally expensive and AFAIK the explicit call to Arrays.sort() was unnecessary prior to Android 2.2.
In addition to seeing this order change on the Nexus One, it can be confirmed on the emulator running level 7 and level 8 AVDs.
I am interested in activating another application's activity. I know from reading the Android SDK that it's probably better to do this with an implicit intent. However, this activity doesn't reside in an application I own, so I don't know the action and category and data flags on the intent-filter.
How can I examine an Android applications metadata like the activity classes and the intent-filters for those activities (if declared in the manifest)?
Anything out there that can help keep app browsing secure and safe?Also anything that can be added to the standard browser to put browsing restrictions on without having to turn it on and off with every reboot?

I am trying to create a program to deal with .torrent files that are clicked on and/or downloaded by the browser. Currently the downloader reports "Cannot download. the content being downloaded is not supported on the phone"
Im fairly sure this is doable as i recently encountered the same issue with pdf files untill i installed a pdf reader.
I'm currently exploring Broadcast Receivers and Broadcast Intent. There are some aspects of the tutorials which are ambiguous to me. To my knowledge this is how the process works. I can broadcast an intent from my application and any receiver on the phone can act on that intent as long as the actions match. I can register a broadcaster receiver on anything that extends Context and when I do so I must provide a filter which will allow the receiver to act on one or more intent actions.The part which confuses me is defining a receiver via the manifest. Must the name of said receiver match a class name? Why should I ever define an intent filter with an action in the project manifest if I always have to provide another intent filter when I register my receiver in code?

View 3 Replies View RelatedI am configuring a tablet for my grandparents, and I am struggling to find an Android keyboard which arrange keys in alphabetical order (A B C D ...) instead of QWERTY.
I am not looking for a keyboard with combined keys using dictionaries like dialpad/T9 (which would be too complicated for them), I just need a basic keyboard with one virtual key per letter.
I thought that this would be very common and easy to find, but it's not The only applications that I found are :
Keyboard for Senior Citizens : would be perfect but does not scale up correctly on tablet.
Keyboard for Dyslexics (lol) : seems to be exactly the same as the "senior" version, did not try because it s an other pay app and has same developer, screenshots and description.
Kids Keyboard : Scale problem in landscape on tablet : too small.
Alphabetical Keyboard : takes the whole screen in landscape on tablet.
Simple Large Button Keyboard : Scale problem in landscape on tablet : too small.
SlideIT English - ABC pack : layout addon for SlideIT keyboard, but I don't like the suggestion panel remaining on the top.
Dextr Alphabetic Keyboard : the only functional from the list, but I would rather use a design closer to a traditional keyboard.
If any better keyboard with ABCD order or a keyboard which would let me customize the layout, I would be very interested.
I added an intent filter to one of my activities, so that when a user clicks a URL like "www.mysite.com", and if my app is installed, my registered activity can be launched. It works well.
I see that this creates a new instance of my registered activity though, every time a link is clicked. Is there any way to prevent multiple instances from being created - just recycle an existing instance if one already exists?
It appears the alphabetical sort setting is not retained on reboot of the Incredible. It reverts to "newest" link sort option, and I have to reselect A-Z. That being said, I've added a "*" (or "_", etc.) at the beginning of the name of each of my most-used 5 or 6 bookmarks, and it positions them, conveniently, at the top of the alphabetized list.

Does anyone else have problems with the music player ordering your songs in alphabetical order instead of in the order they appear on the original album? I've never had this problem with iTunes or iPhone, but with Droid X, all of my MP3 albums are ordered in this way. (FYI, the issue is the same if it's an actual MP3 or AAC format.)
