Android :: Background Color For Market Application Icon?

Nov 18, 2010

Now the Android Market requires developers to upload a: Hi Resolution Application Icon, 512w x 512h, 24 bit PNG or JPEG (no alpha) Problem: my application's icon is not a square, and because alpha is forbidden I will have to fill with some color like black. Or maybe white. Which color should I choose?

Android :: Android - Color State List Resources - Specify A Background Color

Oct 17, 2010

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 then animate the alpha of the currentColorView to zero. At the end of the animation I swap the positions of the views and repeat the process.

Android :: Resetting The Background Color Of View

Sep 8, 2010

I'm trying to restore the background Color of a View. I have several selectable Views. When the user clicks one of those Views, the following code is executed and the View becomes Yellow:

View newSelection, previousSelection;

...

if(previousSelection != null) {
previousSelection.setBackgroundColor(Color.BLACK); // problem here
}
newSelection.setBackgroundColor(Color.YELLOW);

However, I want to reset the color of the previously selected View. However, I do not know which color it was (I'm setting it to Color.BLACK in the above code). I was not able to find a getBackgroundColor or similar method in the View class. If I had it, I could save the previous color and just put it back when the new View is selected.

Android :: Selector On Background Color Of TextView

Aug 28, 2010

I'm attempting to change the background color of an Android TextView widget when the user touches it. I've created a selector for that purpose, which is stored in res/color/selector.xml and roughly looks like that:

CODE:................

The clickable attribute of the TextView is "true", in case that's of interest.

When I assign this selector to a TextView as android:background="@color/selector",

I'm getting the following exception at runtime: ERROR/AndroidRuntime(13130): Caused by: org.xmlpull.v1.XmlPullParserException: Binary XML file line #6: <item> tag requires a 'drawable' attribute or child tag defining a drawable

When I change the attribute to drawable, it works, but the result is looking completely wrong because the IDs appear to be interpreted as image references instead of color references (as the "drawable" suggests).

What confuses me is that I can set a color reference, e.g. "@color/black", as the background attribute directly. This is working as expected. Using selectors doesn't work.

I can also use the selector as the textColor without problems.

What's the correct way to apply a background-color-selector to a TextView in Android?

Android : How To Set Background Color On Open GL ES Droid?

Sep 27, 2010

I am currently playing about with lesson 08 here http://insanitydesign.com/wp/projects/nehe-android-ports/ I would like to change the background colour from black to white. In order to do this at the start of onDrawFrame() I have called gl.glClearColor(1.0f, 0.0f, 0.0f, 0.0f); This does indeed set a white background screen, but also results in nothing else showing up on the screen! Clearly this is therefore an incorrect method, but why, and how do I fix it?

Android :: How To Highlight Background Color Of Row When Tick Checkbox?

Jan 25, 2010

I have a list of checked items. I used the simple_list_item_multiple_choice.xml layout from android from the list. My requirement for this list is- When I check the checkbox of an item, the background color of that row will change. (For e.g. black background to green)- Then when I uncheck the checkbox, the background color of that row will back to original (green to black) Is there any way to implement that? What I want here is different from the orange color when you scroll the list, which is made by default for the list in Android.

Android :: Changing Background Color Of ListView Items?

Feb 7, 2010

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.
