I have a ImageView with a Picture in it. When I touch the Picture through the TouchScreen, how can i get the ColorCode (eg. 0xff0033933) from the x/y Coordinate I clicked?
Something like: onTouch.GetColorCode (from the pixel bellow my finger)

I have a listlayout with items in it that looks like this:
There is first an ImageView (the light) and then two textViews. All of this inside a TableLayout. (source here: http://code.google.com/p/switchctrl/source/browse/trunk/android/res/layout/device_switch.xml)
I want to have a rotating animation of a loading indicator Ontop of this light when this particular device (light) performs an action or an action is performed on it.
How do I put an animation ontop of this light imageview?
I need to set alternate color in list view rows but when i do that it removes/ disables the on focus default yellow background
I tried with backgroundColor
rowView.setBackgroundColor(SOME COLOR);
also with backgrounddrwable.
CODE:.........
But it wont work. is there any way we can set background color and on focus color simultaneously which will work.
Is there any process to change the default text color white to "Black" and default selection color of android "orange" to "Blue" for whole project. i am using Eclipse for Android development.
View 3 Replies View Related1. I want to use my own color for selecting ui views.
By default, android shows the selected view with background as orange. I want to show the view background color as red.
2. In the same way, I want the same behaviour should be applied to whole application.
I have seen this example:
@*android:color/secondary_text_light
What's that * asterisk doing there? What is the difference when using or not?

View 2 Replies View RelatedIn android, when I press on a TextView, the text changes color (from white to grey). how can I disable that functionality?
View 1 Replies View RelatedI got a little textview defined in layout xml:
CODE:.........
As you can see the background color is "background_light" (this results in white color) and the text color is "primary_text_light" (this results in black color).
I would have thought that primary_text_light would result in a "light" color like white, not black ;-)
When i change "primary_text_light" into "primary_text_dark" the text color becomes color white.
Is this a bug in the naming of the default colors?
To 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?
I'm programming my first Android application and I've stumbled over a little problem.

View 1 Replies View RelatedI'm trying to create a color picker for Android that looks like a minimalistic version of Gimp's. So, it has a hue slider and a rectangle with saturation/value variants of a color chosen in hue slider.
Question: what is the best way to create the rectangle?
Right now, I'm creating an 200x200 array of pixels, but it takes ~5sec to create and display rectangle with that array. And I need colors in rectangle to change whenever I change the value in hue slider...
Rectangle is bitmap, Can I use color matrices on that and how?
I am having custom Listview. Every row in listview contains image and textview.
After finishing the page I want to execute a thread which will get the reference of all the rows then will extract imgeview and set resource image as lazy loading image.

View 2 Replies View RelatedI have an ListActivity that I wan't to add a logo to at the top above the list but I'm unsuccessful. This is what my layout looks like at the moment.

Question on an oddity I am seeing.
I have an ImageView that I am using to display a splash screen for a couple of seconds:
CODE:..................
I'm using Android 1.6.
I'm wondering if there's a simple way to put text on top of an ImageView element. Specifically, I'd like to have text overlayed on top of a rectangle filled with a color gradient.
I have the following in my XML layout:
CODE:................
But the text specified in android:text doesn't show up in my view.
Any thoughts on how to overlay text on top of an image?
There might be a simpler way to do this, so I'm open to alternative suggestions but I haven't been able to find anything via the google.

As you might notice here, i'm doing them with an overlap since the uer should be able to pick up the last card and should therefore see it, but the other 4 are just so he'll know what was thrown lastly. my problem is: in the begining the imageviews have no src, but once i give them an image source

I dont know how i can undo it - i can't set the imageResourceId to null since it is an int type so is there something like -1 or some constant value that means null? i know about visibility, i'd rather not use it here unless i really have to, since it'll require a bunch or refactoring that i prefer to avoid...
