Android :: Calling TextView.setText() Periodically Causes UI To Jerk
Sep 28, 2010I'm coding an audio player where a thread updates the TextView representing the track's elapsed time, every 250 milliseconds. The display looks like this:
1:30/2:30<-----Progress Bar----->
TextView 1 is 1:30/ and TextView 2 is 2:30.
Both are set to wrap_content for width.
What happens is that on every 250 millisecond cycle, the thread checks the current time and updates TextView 1. For this brief moment, TextView 2 and the progress bar get pushed momentarily to the right by about 2-4 pixels. Then they come back to place until the same thing happens during the next cycle. I don't know what's happening. There are no trailing space characters, etc and everything should, theoretically, be working smoothly but it's not.

View 2 Replies View RelatedAndroid :: TextView Always Loses Focus After Orientation Change / Is This Bug?
Jun 11, 2009When changing screen orientation while running an Activity that has both a normal layout and a layout-land file defined (both of which contain a TextView), then that view loses its focus after being restored and a warning is issued on the log:
"Previously focused view reported id X during save, but can't be found during restore."
Is this a bug? I looked at the mID field of that view, and it's identical for both the portrait and the landscape layout.

Android :: How To Change TextView TextColor When Parent Is Focused
Oct 17, 2009I have a TextView inside a LinearLayout. The LinearLayout is able to receive focus, and I want the textColor of the TextView to change when it does. I thought using a ColorStateList would work, but it would seem that the TextView does not receive focus when the LinearLayout does. I know that, because I have tried this code...
And nothing gets logged. I don't want to use an OnFocusChangeListener on the LinearLayout to change the textColor of the TextView, I think this has to be done from XML. The reason for that is because in another activity I have an ExpandableListView with a custom adapter and custom views and Android changes the textColors of the TextViews (from light to dark) inside my custom views when items are focused.

View 1 Replies View RelatedAndroid :: Dynamically Change Text Color Of A TextView Inside A ListView
Nov 18, 2010I'm trying to create a game lobby for a project, and I'd like the game's status text to be a different color: red for an "[IN PROGRESS]" game and green for a game that's "[Waiting for x players]". The ListView will be populated with data, and each ListView item will have a game ID and then immediately to the right of that the game's status.
Right now I'm essentially using the Hello ListView code to create my ListView.
(In constructor)
CODE:...........
Then, I have a refresh button that obtains data from our database. It will get two Strings, one for the ID of the game, and the other for the status of the game. If the game status is 0, then it's still waiting for players. If the game status is 1, then the game has started. So, I create a gameItem to add to the gameList:
CODE:.............
This is where I'm stuck. I don't really understand how I can alter the specific TextView when I create the gameItem or when I add that to the gameList. There isn't a way I can see of accessing the TextView's properties. I see how the text of the view is set (through the mapping of the strings to "line1" and "line2", but I don't know how to change any of the properties.
Android :: Change Textview Text From String Array In Widget Without Global Variables
Nov 21, 2010I am trying to make an android widget like the Google Voice Widget where users can go through an array of Strings which is retreived from the SQLite database.

HTC Desire :: GPS Periodically Turning On?
Sep 4, 2010I have a Desire on Vodafone in the UK. Upgraded to Froyo using the official method the other week. Not sure if it is since then, but it's happened a lot the last few days, and it definitely didn't do this before the upgrade, but it seems that my Desire is now turning on GPS every few minutes - the icon flashes away in the notification bar. I have no idea why. Any idea what's happening, and how I can work out what app is causing this?
View 4 Replies View RelatedAndroid :: Periodically Check If GPS Get New Data
Jul 25, 2010I have successfully been getting GPS data through the registerLocationListener() and onLocationChanged() methods. The only problem with this is that the speed reading of my app freezes if there is no more GPS data (e.g. when I go indoors, enter a tunnel, etc). The behavior I want for my app is that the user is somehow notified that the speed reading is probably not accurate due to a lack of fresh data (set speed to zero, blink the speed reading, etc). How can I do that? I though of checking periodically whether the GPS unit was detecting any satellites, but I'm not sure how to force periodic checks.

Android :: Scanner For Wireless Networks Periodically
May 26, 2010I'm developing sort of a wireless scanner, so I need to scan every X seconds. I know I should use WifiManager and startScan() to get the networks and then register a receiver to receive the event once the scan has finished. However I'm having problems when trying to figure out how to scan periodically. It's more like a design problem. My solution so far has been to create a Service which takes care of the scanning, besides the main Activity.
I think this is correct. So, how could I tell this Service to scan every X seconds? I've thought it may have a Thread object, call its Scan method during tart_services() and then take it to sleep. Also I thought I could just get rid of the Service and run the Thread from the main Activity, but then I guess it would die whenever the Activity is not visible. None of then seem like a really good solution to me, and I think there must be an easier way to do this.
Android :: App To Periodically Check If Wifi Network Up?

View 1 Replies View RelatedAndroid :: Backing Up SMS Periodically (possibly Timestamped)
Dec 18, 2009I currently use SMS Backup & Restore, but that has two drawbacks I see
-I have to manually initiate the backup
-It only stores and restores one file, so I have to overwrite and rename
I just lost my texts and only had a two day old backup. I'd love to see the same thing but that can do it with a timestamped file such as backup_2009-12-18-15-08.xml (pickable when restoring) and can run at a preset time each day or each half day.
