Android :: How To Set HorizontalScrollView's Initial Offset?
Jun 22, 2009I searched the groups to find a topic about setting horizontal scroll view's offset, but no results. Some topics talked about ScrollView, and they are not expected. Here is my question: I have a HorizontalScrollView, with LinearLayout as its child, the LinearLayout contains a custom view, I finished the onDraw method of the custom view to draw something which is longer than the screen's horizontal size, so I think HorizontalScrollView is the right widget that I need. But I do not want to display the left-most part of my custom view, such as a calendar, I can display the last week and next week in the custom view, but what I want to put in the center of the scroll view is today. So, I wonder how I should set the initial offset of the HorizontalScrollView?
View 2 Replies View RelatedAndroid :: Move To Next ImageView In HorizontalScrollview?
Apr 19, 2010I have a horizontal scroll view and there are four images in it. Now what I want is the way to detect which image is focused currently. I mean, is there any way that we can distinguish between the image that is focused and other images. Currently all the images look quite similar.
One more thing, how to move only to the next image on every swipe or fling.
Moreover, I have tried the same thing with Gallery, but I didn't found anything in the Gallery that let me move to the next view only. In Gallery, I have tried overriding the onfling method with hardcoded value for veloctiyX but with no success. Can someone let me know how to do this?
Doing the same thing with either Gallery view or HorizontalScrollview will solve my issue.
Hope to get the quick response.

View 1 Replies View RelatedAndroid :: Improve HorizontalScrollView That Has Lots Of Views / Images Inside?
Jul 7, 2010I have a HorizontalScrollView that has lots of views and images inside it.
The issue is that if I have lots of stuff inside it I will get a 'java.lang.OutOfMemoryError: bitmap size exceeds VM budget'
is there any way to use some kind of cache, or add/remove stuff as I move left/right so its not on memory all the time?
Android :: ListView Items Not Clickable With HorizontalScrollView Inside / Make It?
Jun 6, 2010I have quite a complicated ListView. Each item looks something like this...
In my activity, when an item is created (getView() is called) I add dynamic TextViews to the LinearLayout inside the HorizontalScrollView (besides filling the other, simpler stuff out). Amazingly, performance is pretty good.
My problem is that when I added the HorizontalScrollView, my list items became unclickable. They don't get the orange background when clicked and they don't fire the OnItemClickedListener I have set up (to do a simple Log.d call).
How can I make my list items clickable again?
Edit: setting android:descendantFocusability="blocksDescendants" on the topmost LinearLayout seems to work. I'd like to know if there are other ways, though: what if I want focusable items in my list items?

May 30, 2010I have a widget that periodically updates itself (hourly) to display top result of search query. I would like to extend it so it captures several top results and then loops through these. The best example would be Genie News and Weather widget for which I was unable to find a source code. What would be a good way to implement the animation? I'm thinking ViewAnimator + timer, but is there maybe a better way, say FrameLayout + alerts? I'm already using AlertManager to periodically pull search results for the widget How bad such arraignment would affect phone's battery life?

What is the functionality about the 3 files in directory gps. Should I modify the 3 files to implement GPS. In this web site http://www.netmite.com/android/mydroid/cupcake/development/pdk/docs/g..., it shows that anyone that want to integate GPS with Android should create a shared library named libgps.so refer to gps.h. My question is how to create a shared library libgps.so.If the libgps.so is created, where can I find it. What is the relation between libgps.so and libhardware_legacy.so. 3.How to test GPS if gps is implemented successfully. I know there is a gpstest tool in Android but I don't know how to use it.

Mar 15, 2010Say I want to define that an URI such as: myapp://path/to/what/i/want?d=This%20is%20a%20test must be handled by my own application, or service. Notice that the schema is "myapp" and not "http", or "ftp". That is precisely what I intend: to define my own URI schema globally for the Android OS. Is this possible? This is somewhat analogous to what some programs already do on, e.g., Windows systems, such as Skype (skype://) or any torrent downloader program (torrent://).

Nov 22, 2010Let's say I randomly generate a number 0 to 100. Where 0 is really cold and 100 is red hot. Wen the number hits, it would show an image bar (kind of like a % finished bar) that shows in the image what # you hit.
So it would kind of be like a progress bar from 0 to 100, and whatever # they hit it shows in the image of the bar in an imageview?

Android :: Implement Your Own LocationProvider?
Aug 3, 2010I would like to implement a new LocationProvider. In this case, one that uses OpenCellID.org. I figured the pattern wou be quite similar to providing an AccountAuthenticator but was stunned that I could not find any documentation on this.
Looking at the source http://www.netmite.com/android/mydroid/frameworks/base/location/java/... all the relevant code seems to be in a service providing the ILocationManager.aidl -interface that I cannot navigate to or find using Goole Code Search.
Is it supported to provide your own LocationProvider at all? If so, what do I have to do to acomplish this?

View 2 Replies View RelatedAndroid :: How To Implement A Service?
May 3, 2010I'm brand new to android and developing in general. I'm using android's SDK with eclipse Galileo. I've followed several tutorials to create different layouts. I've even learned recently how to use radio buttons and verify which ones were selected. Now I need to create a service that downloads and updates an xml file within the application. I've tried to locate a simple tutorial for services on Google's developer site but so far, so bad. If they exist could somebody point me in the right direction?
On the other hand, I've been told Google's tutorials are a little out dated. Is that true? If so, are there any other tutorials that would hand-hold (and possibly over-explain) how to use a service to a true newbie for free (like google)?

View 2 Replies View RelatedAndroid :: How To Implement - Undo For SQLite DB Changes
Nov 1, 2010I am trying to adapt my application from a confirmation model to an undo model. For those of you who don't know, this is where you can delete something with one click but if it was a mistake you can undo it just as easily, as opposed to interrupting the user every time he/she wants to do something to ask the annoying "Are you sure you want to...?" question via dialog.
My app is backed by the Android SQLite DB and I want to be able to undo a limited set of delete and update operations. Also, I only need to be able to undo one sequential change and the information does not have to stick arround for very long.
Everything I read on undo/redo says to use a command model to store the data. My question is how can I store the database changes in a lightweight restorable way?

Can mutually exclusive preferences be implemented? Pointers or suggestions are greater appreciated.
