I have a TextView that lives inside a LinearLayout. When I call LinearLayout.setSelected(false) the TextView text changes from white to black. Is there a way to set the unselected text color to something else?

Here is my Java code:
CODE:............
This works when I use Color.RED or Color.GREEN, but when I use my own colors. The color doesn't show up.
In the string.xml file i use the following tag
<color name="mycolor1">#F5DC49</color>
if i use : textview1.setTextColor(Color.CYAN);
it works, But :textview1.setTextColor(R.color.mycolor1);
This is not working.how to use the color tag in android?
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?

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?
Say for example I have a textview in class A,
and I want to change background color of textview from class B through a method...
how can I do it?
I'm currently using something like: TextView.SetBackgroundColor(Color.WHITE); in my java code. I'd like to be able to add some transparancy to the textview through the java... This is easy to do in the XML via #AARRGGBB format, but I have not found a way to accomplish this programmatically.

I would like to do something similar to the Twitter app, in which a part of the text is blue. See image below..
I have a textview in my XML layout file, but when I try to change its text value with code pragmatically (dynamically, depending on which button the user clicks) then the text of the textview doesn't change.
This is the code that I tried:
TextView userText = (TextView) findViewById(R.id.User);
userText.setText(bundle.getString("user"));
In debug mode, I can see that usertext has the changed text, but the change doesn't appear on my mobile window... I don't know why.
EDIT: SOLVED! it was a problem with my relative layout, text is out of the window!
I'm trying to change the color of a horizontal progress bar (foreground). I came across this example and am trying to model my XML file off it. However, I get a compiler error at the following statement: myProgressBar.setProgressDrawable(R.drawable.progress_horizontal); The error is "The method setProgressDrawable(Drawable) in the type ProgressBar is not applicable for the arguments (int)." I believe the reason is inside the R.java file I see the following line:..................

View 4 Replies View RelatedI'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.

I have a listview with custom rows and that extends SimpleAdapter.
Each row consist of two linear layouts : 1st having two textviews of which one is hidden in horizontal orientation, second having two textviews in horizontal orientation.
Now depending on the value in hidden textview , I want to setcolor for the remaining items for the row.
To put it as simple:
each listview item has some custom colors the value of which comes from the hidden field.
I have done this by overriding getview() for the simpleadapter and returning view for each, but this makes list very slow to render (and that I think is obvious as so much of work for each view before showing it).
Can I do this in some more efficient way ? like making views and then add up to list instead of using xml layout maybe one solution OR any other?
I am having a bit of trouble with my current application. With a button at the beginning of my app, I send out Intents for two activities, one gets a camera object, and starts a preview screen. On top of that, in a separate layout, there is an activity with a translucent view, which shows a resource image (the user is trying to get the image he is actually taking to align with the translucent image) and a couple of textviews displaying a target phone orientation as well as the user's current phone orientation.
when I update the text value of one of my text views in my onSensorChanged() field, the system constantly reallocates 1.22MB and garbage collects it. I can only assume that this is because it is redrawing the entire layout with the translucent image and the text fields, because if I remove the view containing the translucent image from the layout, my text field updates 10x quicker and I don't have ridiculous heap growing / garbage collecting. I am wondering how to go about getting the text fields to update without redrawing the entire surface. I am very new to UI design, and this code was written by someone else before I took over the project, so I don't understand much of what is going on in the custom view he wrote to take care of the translucent image -- called MyView. I will post the code for the layout as well as the MyView code below.................................
i'm working on an android application with 2 activities.
The first activity contains 2 buttons ( btn1 , btn2).
The second activity contains a textview and a back button.
In the string.xml I have two strings ( str1, str2).
What I want is when I click on btn1 the second activity should open and the textview will show the first string str1 and when I click on the second button btn2 the second activity open and the same textview show the second string str2.
