I followed this tutorial to create a color state list for a particular Android view. I just want it to highlight when clicked so the user knows why the screen just changed.
When the view is rendered, I get the following error:

i'm currently developing an application for android. Therefore i want to create a microphone widget, like the one in googles Searchdialog. This icon is filled with white color, like a bargraph, depending on the recorded volume level. I already found the icon (ic_btn_speak_now.png) in the drawable ressources, delivered with the SDK. Unfortunately the icon isn't an simple shape with a transparent area for the microphone shape. Instead it consists of some different gray values. My question now is: How do the google developers (and others, where i've seen it) fill only the microphone shape of the icon with color?
View 3 Replies View RelatedI'm trying to use a color defined in a stlyle in a selector but it is causing a Resources$NotFoundException.
First I added a new attribute to attr.xml:
CODE:..........
Then I defined that attr value in styles.xml:
CODE:..........
Then I tried to use that attr in my selector definition:
CODE:................
Lastly, the activity uses the ThemeNoTitleBar style theme in the manifest.
I've also tried creating a color in colors.xml and having it use the new attr but that also fails.
I'm obviously missing something but am not sure what to do to fix it. My intent is to create multiple themes and have the selector use the color in the currently selected theme.
I'm going through an Android tutorial and I'm trying to access a color I've defined in colors.xml
<color name = "my_background">#3500ffff</color>
Then I'm trying to access this color by name:
Paint background = new Paint();
background.setColor(getResources().getColor(R.color.my_background));
but it doesn't recognize my_background as a resource. If I let the suggestions come up, only a bunch of pre-defined colors pop up that are unrelated. Any ideas? It doesn't make sense for me, I see almost the exact same thing from the developer documentation and another site, but it doesn't work for me.
Seems my original post ("ugly pngs...") somehow disappeared :( nvm.
I have a problem with a png resource that has gradient fade-out alpha.
The png looks great in the emulator, but displays an artefact known as "color banding" (http://en.wikipedia.org/wiki/Colour_banding)
Has anyone surpassed this issue ?
My designer wants to trop a shadow behind his icons, and that's where the bands appear.
What are my options ?
I've seen this code on the web...

2. How do I get the 0-255 value of the grayscale?
I have a ListView with the fast scroll enabled. The background of the listview is white and the text is black. The box indicating the letter of the section is being scrolled at the moment is in black. Is it possible to customize that color and turn to white? If yes, how can I do that?

Using XmlPullParser, on the START_TAG, I can use:

to get values 1, 2, 3...however:

doesn't work...it just yields the default value 0, or whatever I change the default value (3rd parameter) to be. Does anyone know what I am doing wrong or if this is possible?
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

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.

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?

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 trying to pass location data from my application to the Google Navigation API (No, not the browser). I can pass data to the dialer, and call a phone number successfully, but now wish to use the turn-by-turn navigation as an additional function.

View 2 Replies View RelatedDear Android community, i've a license/legal question regarding asking Google directions to be drawn directly into the MapView. Some of you know that asking google http://maps.google.com/maps/nav will give directions in Json + a Polyline encoded form.What i would like to know is, where is the Terms of Service regarding this functionality? It is for Google internal use or not? There's also the KML which gives similar informations. Please note that it is NOT for real time driving directions but a path to be drawn from a point to another and your position NOT refreshed in real time and of course it is for an app downloadable free of charge.
