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?

Actually, what I want is a textview which can show the progress of something, I know progressbar in android,however,so far as I know, it can not contain any text(am I right?), so, I want to change the background color of the textview to show progress,from left to right gradually.
Is there any other way to do this?

How do you animate the change of background color of a view in Android?
For example:
I have a view with a red background color. The background color of the view changes to blue. How can I do a smooth transition between colors?
If this can't be done with views, an alternative will be welcome.

I've noticed that changing the background color of an android widget (f.ex. Button or TextView) by program:
myButton.setBackgroundColor(Color.BLUE);
makes it to loose its 3D shape, border, and shadows effects, and then appears like a ugly flat square. What am I missing?
Sorry for the very naive question but I couldn't get it right although tried for a time.

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?

Somehow when I select icons and menu items now, it's bright red.I'm pretty sure it wasn't there before.Where can I change that back? What was the default color?Even if someone doesn't know the answer, can someone at least select any icon on one of their home screens and tell me what color the background turns.Argh, there's got to be a way to change it.

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 was wondering if someone has a good answer to this.I am looking for a better way to animate a background color transition from on color to the next.Currently, I have two views, vCurrentColor which lays on top of the vNextColor, in a FrameLayout. 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.

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.

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?
