Say for example I have a textview in class A,

Actually, what I want is a textview which can show the progress of something, I know progressbar in android,however,so far as I know, it can not contain any text(am I right?), so, I want to change the background color of the textview to show progress,from left to right gradually.
Is there any other way to do this?
I'm attempting to change the background color of an Android TextView widget when the user touches it. I've created a selector for that purpose, which is stored in res/color/selector.xml and roughly looks like that:
CODE:................
The clickable attribute of the TextView is "true", in case that's of interest.
When I assign this selector to a TextView as android:background="@color/selector",
I'm getting the following exception at runtime: ERROR/AndroidRuntime(13130): Caused by: org.xmlpull.v1.XmlPullParserException: Binary XML file line #6: <item> tag requires a 'drawable' attribute or child tag defining a drawable
When I change the attribute to drawable, it works, but the result is looking completely wrong because the IDs appear to be interpreted as image references instead of color references (as the "drawable" suggests).
What confuses me is that I can set a color reference, e.g. "@color/black", as the background attribute directly. This is working as expected. Using selectors doesn't work.
I can also use the selector as the textColor without problems.
What's the correct way to apply a background-color-selector to a TextView in Android?

I'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.

View 1 Replies View RelatedI made a custom widget (which is just a composite like):
<LinearLayout> <TextView> </LinearLayout>
this widget is focusable and reacts to touches. I'd like it to change its background color to the default system highlight color when the user scrolls to it, and have it blink when the user taps it (just like an element of a ListView does).
I can add an OnFocusChangeListener for when the user scrolls to it, and in the handler do the changing of the background color.
How would I add the 'blinking' behavior though when the user just taps it with a finger? I did something like this as a test code...
this is just a guess. Is there a correct way of implementing this behavior?
