I have a problem while using the scroller in my application. I have used the scroller but it is not working properly as it is not able to maintain a consistent speed while automatically scrolling. The speed of the text is getting slower with time as the text moves upward.

View 7 Replies View RelatedI create a LinearLayout (orientation horizontal) which contains some TextView. The LinearLayout has a size of 1200px. When user move on, the screen, I would like to do like the Launcher application. I tried to use startScroll function. even if I set a distance, the layout doesn't move alone. Only distance did by user is slided. Does startScroll move alone all content? If yes, why my code doesn't work?

I would be grateful if anyone could please help me out in this, on how to use a Scroller in an activity.
how I can add a horizontal and vertical scrollbar for an EditText? I need it to be done through java code and not through xml.

View 1 Replies View RelatedI have a TableLayout with a tableRow and a horizontal scroll view in the 2nd column, but the right side always gets cut off. IF i have only 1 tableRow, it works, otherwise it goes past the visible area of the screen. To simply and isolate the problem heres an xml file with the guilty culprits. It seems basic but i have been super frustrated trying to get this to work.
. for some reason Stackoverflow isnt displaying my code correctly, heres a pastebin.

The Contacts app shows a button on the side of the screen that acts as a little thumb to allow you to quickly scroll the big list. I have a very long list that would benefit from this navigation behavior, but can't find any documentation as to how to enable it.
Is it a behavior that's built into the SDK, or must I write it myself?
The requirement is totally simple: I want to have a lite and pro version of an app. There is a little bit of difference between those two apps, but they are 99% identically. Unfortunately it seems that the best choice is to really treat this as two projects that are one and the same and copy over the source code and assets from one to the other. The Android Manifest file must be different, because the Android Market - for some reason - makes the implementation's package name the ID. Working around this ID issue the straight forward approach would be to have a third project with the common code that exports its code, libraries and in a best case scenario also the ressources to the other two objects. Unfortunately this doesn't work. Only the actual Android projects generate the R.class and so the common project would need to be dependent on it..

Am I slowing down execution by decoding the resource every time? Is it better to store every image into a Map (or Dictionary) at the beginning of the program? If so, how do you get the resource IDs for all images in the drawable folder?
View 1 Replies View RelatedI would like to know if its possible to prevent my application from looking different every time I run it on a different android phone. For example, on stock 2.2, my seek bar (with default values and theme) has an orange color for the selected portion, whereas on a Samsung Galaxy S (with 2.1), it is green. Also the tab background is grey in stock 2.2, but blue in Galaxy S. On a similar note, my rating bar changes size too. I do not implement multiple screen resolutions and all my drawables are located in the "drawables" folder under "res". I donot specify a minimum sdk requirement.
View 5 Replies View RelatedMy ListActivity is bound to an ArrayAdapter where I have overriden the getView() method. If I change the visibility of a widget in that method or modify the view's background color, those changes somehow get lost once that modified list item returns after being scrolled off the screen. In fact, some other view in the list is picking up the changes. How do I get the modified view to look the same when it's redisplayed after scrolling?

View 1 Replies View RelatedThis usually happens when the user hits "Home", does something else, then eventually wanders back into the app - it attempts to go back to where it was before, but the application Context has mysteriously lost all its previously-saved state information (in my case, a few integers and a few Strings). I know this is a very vague question, but are there any cases (other than the user using "back" to back completely out of the application) where the application Context gets completely destroyed even though the application is not terminated? Is there a better way to maintain persistent state information?

The app does not need to be able to directly access the credit card's balances online (straight thru online banking), but I must be able to add transactions and update it manually. I also should be able to manage multiple cards without the app adding the balances of all cards into a grand total (balance).

What are the required APKs to maintain running the Android OS? I have root access on my Eris, and was tinkering around with a bit with removing some of the preinstalled APKs such as YouTube and stuff like that, just wondering how much I can delete and work to create my own system to a certain extent. Anyone that can let me know what I need would be nice.
I have built an app for the Motorola Droid which should automatically update a server with the phone's location. After the user performs a particular task on the main activity screen, an alarm is set to update the user's location periodically, using a service. The alarm is explicitly stopped when the user completes another task. Thing is, I have set up a location manager within the main activity's onCreate() method which is supposed to place the first acquired lat/long into two textview fields. Even though the manifest is set up for acquiring coarse and fine coords and I'm using requestLocationUpdates (String provider, long minTime, float minDistance, LocationListener listener), with minTime and minDistance set to zero, I'm not seeing the coords coming up on the screen.
With that, I'm not recording any locations on the server. When I seed the textviews with sample coords, they are being recorded fine on the server. I am not at a computer that can run the IDE, so don't currently have the code, but am desperate for some help on this. One other thing is that the main activity screen calls a photography app before the user manually clicks "send data". I'm suspicious that I may need to override the main activity's onResume() method to do this location acquisition.
While developing a sample android application I have constructed two activities
1)Activity 1
2)Activity 2
Now Activity 2 is the foreground activity whereas Activity 1 is the background one. Now user presses Home key. The application(i.e. both the activities) disappear. Now is we relaunch the application we see Activity 1 as the foreground activity. My question is:
1)Does the platform maintain any history entry when pressed home key?
2)How do we take the user to the last launch activity on relaunching the application?
I am working on my App. in between i pressed the Home button on the device. my app will go to the background tasks. After that i long press the home button it will show my app as a persistent state. i.e where and what i had done in my app. But i click my app in the directory window it restarts my app. i want to do if my app is in the background tasks it will wake up else it will start. how to achieve that?

View 2 Replies View RelatedI'm interested in knowing how other people maintain good battery life with their evo. I get about 5 hours a day with moderate usage. I don't do much but put the screen brightness in the middle and occasionally going into "running applications" and closing the ones I don't need or use (most of them being the trashy default stuff); Turn off syncing when not needed; turn off GPS and other seetings that are not continuously needed to be left on.
I also configured my send and receive settings for each mail account. I know there is no official way to close out an app when your done using it, I usually just press the home button when i need to exit an app. Does everyone else do the same? Or is there a better technique to officially close apps and stop them running when you are done using them? Without DLing a task killer app cause I don't want one.? Feel Free to share your ideas or techniques.
My Christmas gift this year... the HTC Hero. Quite happy so far. However because neither my hubby (he has a Palm Pre) and I have ever had an android before, I have a few questions that he can't seem to answer. So please excuse the simiplicity of my questions
1)) What is the best way to maintain good battery life? Is there a specific % I should never let the batter fall below?
2)) Besides from being able to pull ringtones from my MP3 files on my PC, are there any good websites that offer free ringtones for android devices?
3)) My Hero came packed with a whole bunch of apps that I will never use. Like NFL Mobile, Nascar, Amazon and YouTube apps. Is it okay to delete these from my phone entirely? Will doing so free up memory for bigger and/or better apps?
4)) Are there any types files or apps that I should not put on my phone?
I have seen this happen many times on my Phone. I have folders on my Homescreen with Shortcuts/Apps in them. Inside a given folder, I have a SPECIFIC ORDER to my Shortcuts/Apps. For whatever reason, my phone will decide to mess up that order that I created. Various things seem to trigger my phone to re-arrange the Icons in my folders. For example, unplugging my phone from my computer after disk use triggers it.
