Android : How Do I Set Color Back To "Color.BLACK" After User Releases Touchscreen
Mar 27, 2010
I'm programming my first Android application and I've stumbled over a little problem.
I've created my own adapter ("extends BaseAdapter") for my ListView and in my "public View getView(...)" I have the following code:
My problem: How do I set the color back to "Color.BLACK" after the user releases the touchscreen?
I'm looking for something that is similar to Javascripts "onMouseUp" or "onKeyUp" methods. An OnClickReleaseListener() perhaps?
Can you point me in the right direction?

I 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?

I noticed if I unlock my Droid and tap an icon, the background will change color, like the app was selected but it won't launch unless I tap it again. This only happens after I unlock the Droid.
Cannot figure out if I am doing something wrong.

I have the beautiful weather widget on my home screen with the clock... Now I want the clock color to go from white to black, but for some reason it stays white even when I change font color to black in the appearance panel. I don't want to change skins as I like this particular clock.. Anyway to do this?

I'm making an Android App, and i need to put a control that let user choose between 4 different colors. I want to do this with something like radio buttons: the problem is that radiobuttons are round...
is there a way to set them looks like square/rect buttons, and assign a color to their inside rect area ?
If not, how can i achieve that choose for the user ?
I need this because i'm making a Todo/Task android application, and i need the user to choose the priority of a task, between for priority level that are rapresented with a color. So i think to do that by showing 4 buttons, each with a different color associated, and a text inside ("0", "1", "2", "3")

1. 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 wanted to see if I could change the top/bottom wrap fading effect seen on most long scrolling components. In this case I would like to change the color from black to whatever color I desire on a ListView.

I wrote application which uses ListActivity. Each item of the list consists of ImageView and TextView. Long click on list entry triggers some menu and color effect because onCreateContextMenu was overridden. Sometimes TextView contains HTML links which I would like to be interactive. I read #1697908 and made links active, so browser/youtube player is started. Everything would be great but color effect on long click disappeared (context menu still appears). Could somebody tell me how to connect these two features and get back color effect?

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 have a 3D game and I am using color-picking to know which object was selected.
When the user touches the screen, I draw each object with a different color. Then I read the color where the user touched the screen to know which object was selected. After that I draw each object with their respective textures/colors. (everything done during one onDrawFrame pass)
The problem is that sometimes the colored objects appear on the screen (~5% of the times the user touches the screen) and it is even worse on slower hardwares.
This is my pseudo code:

I'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'm trying to make it so that as long as a user is touching the button, it shows one image, and when the user releases the button, it goes back to a default image.
I'm trying to use a selector to make this happen:
CODE:...............
I've tried a few things with the selector, but it always produces the same behavior: the button starts out with the default image, then I press it and it changes to the "record_on" image and it never goes back to the default image when I let go.
Is there a way to get this kind of behavior with an ImageButton, or should I be using something different?

I call WebView.clearHistory(), but I am still able to go back after doing so. I want to reuse a WebView, but I don't want the back button to allow the user to go back further than the current "session" of using the WebView. Anybody know what is the best way to handle this? I thought for sure that clearHistory() would do it.

And the following two links were the original png files:

Can anyone explain it for me why it presented in different color?
By the way, the picture was made in 32bit colors png format.
