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.
CODE:..............
However the screen doesn't update. I must be overlooking something...

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 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.
View 2 Replies View RelatedI 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 am using a textview to display some text and I would like different parts of the text to be shown in different colours, e.g. first half of the text in red, second in blue. I cant seem to find a way of doing this. I have heard of using Html.fromHtml() but I am not exactly sure how to do it this way.

The TextView renders with the text that has the word "awesome" bolded and underlined (Yay). However in my view, I cannot focus the subregion of text I specified in the clickablespan. I can click on it with a touch event, but I cannot focus it. I am testing this on Android 1.5 + 2.1. I have also tried UrlSpan as well.
I have also tried instead of using a ClickableSpan, to actually attach an onClick listener to the entire block of text but that doesn't give the region focus, just makes clicking easier.

View 5 Replies View RelatedIs the best way to add some static text to a display to use a TextView?
Seems like there should be a TextLabel or TextStatic or something like that...
I have a layout that looks something like this:
[TextView 1] [TextView 2]
[ TextView 2 spill-over ]
Essentially, I need the contents of TextView 2 to wrap to the next line, but start where TextView 1 starts. I was thinking that if I knew how much text would fit into TextView 2 before it runs out of space on line one, I could take the rest of the text and put it in another TextView below the first two. So I need to measure how much text will fit into a TextView (which can be tricky because as far as I can tell, Android will try to break the text in a TextView at a good location so that it won't break a word in the middle if it can be avoided) or I need a new idea on how to lay this out.
