View 1 RepliesSetting the background color programatically of an android TextView doesn't seem to work.
I'm I missing something!
CODE:.............
I also have this file (colors.xml) in my res/values folder

Also, setting the text color causes the TextView to disappear.

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.
Can I modify android.R.layout.simple_list_item_1? For eg., I want to change the text color of the textview inside the listview dynamically. For this, I need to get to the textview and change its color.. How can I do that?
View 1 Replies View RelatedI am loading a listview dynamically. I have set a .9.png image as row background image. The main purpose of using .9.png image was to extend the height of the image dynamically according to the contents of the listview. But, the image is not getting extended. The contents which can be displayed within the height of the row are being displayed and the rest are being cut.
View 3 Replies View RelatedI have defined a custom theme, where I am drawing a dark gradient on my window background. My ListView background is set to be transparent, however whenever I scroll, the background color turns black, and then after scrolling has stopped, goes back to the gradient color. Why is this?

How can I change background color of ListView items on a pair-item basis. When I use android:backgroundColor in the ListView item layout I can achieve this, however the list selector is no longer visible. I can make the selector visible again by setting drawSelectorOnTop to true but then the selector overlays the whole item.
Any ideas how to change those background colors and keep the selector?
I would rather not change the selector itself.
Authors of GMail application have managed to achieve exactly this so it's definitely possible.

My query is regarding on whether we can apply dynamically themes in android,like what we do with our phones in which we can select a theme and the same theme gets applied all across the phone.Is there a way to do this in android? (I am able to change the default theme by hardcoding in the code (styles.xml),but I need to know how we can we set themes dynamically. I saw the Android phone,but there is no Setting where we can set the Theme.)

View 1 Replies View RelatedI need to create a list view that display same functionality as Contact App. I need to have a scroller through which i can traverse the list alphabetically. To achieve this i am following an example from API demos "com.example.android.apis.view.List1.java". When i implement this functionality on a static list view => it is working fine. But when i try this on a dynamic listview=> it is not working.
View 1 Replies View RelatedTo give the user of my app an indication which field currently has the focus I am trying to change the background color of some of my fields depending on the current state, however, I am having troubles understanding Androids Color State List Resources:
There is this example at the bottom of http://developer.android.com/guide/topics/resources/color-list-resource.html. If I try exactly the same, i.e. if I want to adapt the textColor , things do work. However, if I try an only slightly different thing, namely to adapt the background color, things do not work and I don't understand why? Why is this so inconsistent?
To make it simpler to understand what I am trying to do, I append my misc. .xml files:
The AndroidManifest.xml file:
CODE:.........
If I run this as shown here, it works, i.e. I get a button whose text color changes depending on whether the button is focuses, pressed, etc.
If I uncomment the lower button, where I just flipped the attribute values for textColor and background I get an exception, stating
... <item> tag requires a 'drawable' attribute or child tag defining a drawable
What the heck am I missing here? Why is that color state list acceptable as a text color but not as a background color? How does one specify a view's background color depending on the view's state?
Apparently ProgressBar.setProgressDrawable has bug, if called to set new drawable, progress bar disappears completely. Is there any other way to change progress bar color dynamically at run time?
