Then in my code, I use:

But the username does not display on the screen. I get just the default text in the XML.

I have an Activity with TextView that I am trying to update from different thread. To do that i pass TextView to the "updater" thread onCreate(..) .. txtStatus = (TextView)this.findViewById(R.id.status): start udp server as separate thread and pass TextView to that thread to print text messages from udp socket
new Thread(new TelemetryServer(txtStatus)).start:
see thread code below

Hello everyone, and thanks in advance for the help. What I'm trying to do is a relatively simple task, but one that doesn't seem to be working. What I'm trying to do is display the Orientation X,Y,Z coordinates on the screen in basic TextView boxes. The sensors are constantly updating my Global.myOrientation float array, and then I'm running a Timed thread (I'm very new to threading, so forgive me if it's ugly, but it gets the job done almost). In this thread I just set the value of each TextView's text to the desired value. The problem is that it only seems to work the first time.
It correctly displays whatever my initial data is, but then subsequent runs of the thread do nothign to update the onscreen values when I change the orientation of the phone. LogCat output shows me that inside the run() method, the values of Global.getOrientationX,Y,Z are being updated correctly, and that the right data is being passed to TextView. How can I get around this limitation of TextView being initialized once and then immutable?
Any assistance in fixing this, or providing an alternate solution would be greatly appreciated. Code posted below:

I have an app that uses a TabHost. Several of the Tabs share a common HUD. I am using a service to periodically update those values by calling an AIDL function when ready.
However, since several of the Tabs are using the same HUD I would like to abstract that part out.
I thought about having the HUD.xml use a String resource as it's value and then the abstracted class can update the String resource. However, apparently Android can not update String resources programatically.
The only alternative solution I see would be using SharedPreference.
I have concerns accessing a Database everytime the value is refreshed.

I've got to missing something completely stupid on this one since updating a TextView should be an easy task. I have an Activity class that is an observer of another that receives messages. In my Activity's onCreate I do the following and it works fine.

Anyone having trouble with widgets stop updating? Like my clock/calendar/weather/news/pretty much any widget i have stops updating after an hour. So i look at my clock widget two hours later and it is an hour behind. Happens to ALL my widgets.Even the quick turn on/off wifi,bt,gps and such. They just stop updating/showing animation.I have ADW launcher installed. I am wondering if it is that. I do not really want to remove it as i hate the stock 3 button interface at the bottom (why do i need a contacts and phone, just use the phone to look thru contacts, wasted space IMO) and am quite keen on keeping the 5 button.Any ideas? If i power off the phone and turn it back on it's fine again for about an hour. SOmetimes randomly thru the day it will start updating and working fine again then randomly stop again.
View 12 Replies View RelatedI have a ListView that contains an Image on the left of two vertically-oriented TextViews using a RelativeLayout. When both TextViews have text it looks fine. Sometimes the TextView on the bottom won't have any text, and the problem is that the entire layout is several pixels above where it should be because it still reserves that space for text when there isn't any making the entire list have annoying blank gaps. I remember seeing an example of where someone made the layout not reserve the space, but I can't remember how he did it.

I have a TextView that I created in the main.xml. In my app.java I am dynamically positioning that TextView based on where the user taps the screen. The problem I am having is that when I call myTextView.setPadding(100,100,0,0), it moves the actual Text of the TextView, but does not move the Colored Background of the TextView.

It works fine but everybody says that doing your graphics in the main thread, so I'm trying (and failing) to pass it off to another thread. Trouble is, I have absolutely no idea how since really I've never used Threads.
The examples that Google gives on using Threads doesn't seem to be very clear and I couldn't really follow it for what I want to do. Could I ask somebody out here to give me the most basic example of how I could do what I'm doing here efficiently using Threads?
I'm trying to update the CalLog to change the name/cached name of an entry. I have successfully updated a row but once i go into the call log on my phone the displayed name is removed after a short moment. I figured this is because the number of the incoming called is not found in any of the contacts. But why would it then clear the cached name that is in the Log? If the number is not in contacts the call log should display the cached name without trying to refresh it? At least that's the behavior I expect.My question is: Is it possible to add a name to an incoming number to display in the call log without adding the number and name to the contact list? I've figured it should be possible to add the contact first, then mark it as removed and thus get it displayed in the call log but that seems like a stupid work-around.

When my Activity resumes, I query for a Cursor (by calling managedQuery to retrieve a Cursor pointing at my database using a ContentProvider), call startManagingCursor, instantiate a new CursorAdapter, and setListAdapter to my new CursorAdapter.
Suppose, at some later point, I launch some thread that hits a web service to query for new data to add to that table. Do I need to repeat everything I've listed above again?
I updated my android application on the market.This update included a change in the databaseHelper file where I put in more data and tables. Normally, when debugging, I would have to uninstall and reinstall the app because it doesn't see the new values in the database.Now, it's doing the same thing on the market.
Why is this happening?How can I fix this?Is it possible to 'rollback' the changes to the app?
I'm looking for ideas on how to have a package that is not distributed through the Android Market (it's in closed Beta) upgrade itself.
I had hoped to download the .apk file from my web server and then use PackageManager.installPackage(), but that requires the INSTALL_PACKAGES permission, which is apparently not available to packages not installed in /system/app.
Best idea I have now is to launch an Intent to download the .apk (via web browser), but that would require the user to then manually install the package, which is unkind.
