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:
CODE:.........
My color XML (in res/color/viewcolor.xml):

My layout XML (in res/layout/myview.xml):

I want to change the background image of a button either into a resource drawable or a solid color.
findViewById(R.id.myView).setBackgroundResource( xyz == 0 ? R.drawable.myBackground :
instead of zero, i want some solid color...
I have a linear layout where the orientation needs to be "horizontal" in portrait mode and "vertical" in landscape mode.
There are a few ways to do this, the most obvious of which being to specify two layouts: one in "layout" and one in "layout-land".
However, this will require a certain amount of duplicate XML. I know you can use <include> to minimize this, but at the very least the attributes of the LinearLayout tag will need to be duplicated and two extra XML files need to be created (one layout-land file and one include for the contents of that layout).
As an alternative I do this in the LinearLayout tag:
android:orientation="@string/custom_lang_orientation"
and then: values/strings.xml <string name="custom_lang_orientation">0</string>
values/strings-land.xml <string name="custom_lang_orientation">1</ string>
which is a hack. Its also a bit risky because of the assumption the integer values for horizontal/vertical will not change. However, I suppose this is extremely unlikely. Any thoughts?

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 ?
If I have 2 LinearLayouts split %50/%50 everything is fine. Weights are 1 and 1. As soon as I add a TextView inside the top LinearLayout, it stretches that layout. I use "wrap_content" as the documentation says I should when it comes to weights. As you can see the red and green should be split evenly and text on grey background should be inside red box.
Here is the code:..............
Now if I switch to "fill parent" as follows it actually works but it creates another problem. Here is the code (so far so good):
So looking at above we were forced to use "fill_parent" and we would think like we fixed the problem but here is the problem if we are using "fill_parent" (I took out the textview just to show the problem, textview doesnt make the problem go away anyways):
As you can see I assign the weights 3 (top red) and 2 (bottom green) but what actually happens is they get flipped: The red becomes 2 and bottom becomes 3. Just measure the pixels too see.
Here are the results of the 3 codes: http://imgur.com/iVt8g.jpg
I have a RelativeLayout that has two LinearLayouts in it. One is a bunch of TextViews and EditTexts that make up a form and the other is a ButtonBar that submits the form.
anyways, everything looks great in portrait, but when i switch to landscape mode the bottom TextView/EditText element is being hidden by the buttonbar.
screenshot to show the problem. as you can see some of the "email" textview and all of the email edit text are being hidden by button bar.

I have an XML resource file:
<resources> <section>
<category value="1" resourceId="@xml/categoryData1" />
<category value="2" resourceId="@xml/categoryData2" />
<category value="3" resourceId="@xml/categoryData3" />
</section> </resources>
Using XmlPullParser, on the START_TAG, I can use:
int value = parser.getAttributeIntValue(null, "value", 0);
to get values 1, 2, 3...however:
int resourceId = parser.getAttributeIntValue(null, "resourceId", 0);
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

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 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?
