Is there a way to apply a color to an alpha animation in android? I know how to use the <alpha> element, but i'd like to have the alpha apply a color as well as an alpha so i can hightlight a layout. is this possible?

I'm fading out an imageview with alpha animation. I'd like the image to stay transparent after the animation. Tried with different combinations of fillAfter and fillEnabled, no luck. How can this be achieved?
View 1 Replies View RelatedI've been struggling for a few days on this, finally just decided to ask. It's so simple I've got to be missing something very basic.I have an XML layout page with an image defined. I have two anim XML pages, one to change alpha from 0 to 1, and the other from 1 to 0 in order to create a "blinking" effect. So the alphaAnimation is defined in XML, I just need to call it. The image pops up, but there's no looping blinking effect.

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 ?
Can you advise me how to apply view transition animation. ex: when i click on an list item my contentview changers. I want to apply a transition animation in that.

So far, I have managed to get the glow image behind the logo, using a LayeredDrawable, but I can't figure out how to animate it. I have found that AlphaAnimation would achieve the desired effect, but unfortunately I can only apply it on Views, not Drawables. How can I achieve this effect?

Does anyone know if it is possible to apply a frame animation (using an AnimationDrawable) onto a custom button or a toast view? I have posted these questions on Stackoverflow but have received no responses and very few views so I thought perhaps posting to this forum would be a better route. Let me know if this "double posting" is bad form.

View 1 Replies View RelatedI am trying to apply an animation to a view in my Android app after my activity is created. To do this, I need to determine the current size of the view, and then set up an animation to scale from the current size to the new size. This part must be done at runtime, since the view scales to different sizes depending on input from the user. My layout is defined in XML. This seems like an easy task, and there are lots of SO questions regarding this though none which solved my problem, obviously. So perhaps I am missing something obvious. I get a handle to my view by: ImageView myView = (ImageView)getWindow().findViewById(R.id.MyViewID);
This works fine, but when calling getWidth(), getHeight(), getMeasuredWidth(), getLayoutParams().width, etc., they all return 0. I have also tried manually calling measure() on the view followed by a call to getMeasuredWidth(), but that has no effect. I have tried calling these methods and inspecting the object in the debugger in my activity's onCreate() and in onPostCreate(). How can I figure out the exact dimensions of this view at runtime?
I've created a layout with an image view and a web view. The web view is set to have a default visibility of gone. When the activity fires up it displays the image view first and when the web view has finished loading its url, it marks itself as visible and the imageview is marked as hidden.
When the imageview is shown, I would like it to rotate repeatedly just for a little added pizazz.
I have never done animations before in Android and all the posts I found when I asked the internet were not helpful; thus, I have returned to SO for help.
So if I start with this...final ImageView splash = (ImageView)findViewById(R.id.splash);
How do I create a repeated rotate animation and apply it to the ImageView?
I'm currently using something like: TextView.SetBackgroundColor(Color.WHITE); in my java code. I'd like to be able to add some transparancy to the textview through the java... This is easy to do in the XML via #AARRGGBB format, but I have not found a way to accomplish this programmatically.

Like with AlphaAnimation there is fromAlpha and toAlpha, I need something like ColorAnimation that provides fromColor and toColor. Is there anything like that already?
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.

View 3 Replies View RelatedI have a strange issue - from time to time the animation that should fade out my control (ImageButton) does not kick in immediately. I am using the fadeout animation to hide it and then in myListener on its end (onAnimationEnd) I put new resource as the image on the button.
Somewhere in my app code:
Animation a = AnimationUtils.loadAnimation(this,R.anim.fadeout); a.setAnimationListener(new myListener(location)); buttons[location].setAnimation(a); a.startNow(); // regardless if its start() or startnNow() it will work in most of the cases but not 100% reliable I actually can see in debug Log when its late, happens after few more clicks
Then in myListener.onAnimationEnd(Animation a):buttons[location].setImageResource(R.drawable.standard_button);
Seems there is a rule that the every 4th or 5th animation does not start ...

View 2 Replies View RelatedI have been having issues downloading the latest version of my app as part of Alpha testing. I have uploaded 6 versions and every time i download the app i just get the first version.
Thinking this is something to do with cache on google play store, on few versions, i waited more then 24 hrs for the download. Even this did not work.
Is there anything that i can do to make sure that i download the latest version. All the previous versions are archived and only the latest version is published/active.
Is it possible in Android to get a callback when a Frame Animation (AnimationDrawable) has completed playing its frame sequence? I know when a Tween Animation has completed, it calls onAnimationEnd(), but is there something similar for frame by frame animations?
View 1 Replies View RelatedIs it possible to generate an EGL Config with an alpha buffer on the G1? When I request a non-zero number of bits for the alpha buffer I can get a R5G5B5A1 or R8G8B8A8 visual, but neither of them renders correctly to the screen. I assume that's because the G1 only supports R5G6B5 visuals. It does surprise me that I can even get those visuals though. It's fairly obvious looking at the 32bpp visual artifacts that the frame buffer is indeed laid out with 32bpp, but display hardware is treating it as 16bpp, resulting in the left and right halves of my scene rendering in alternate scan lines, with distorted colors. So does anyone know if there is any way to get an alpha buffer on the G1? I've tried using FBO's but they don't seem to be implemented either. Or I'm using them incorrectly. If I call glGenFrameBuffersOES on a GL11ExtensionPack reference I get an UnsupportedOperationException. I am getting my GL11ExtensionPack reference by casting the return value from my EGLContext.getGL() call.

I was having trouble getting my G1 to render an RGBA_8888 OpenGL context to the screen. Everything was twice the size it should be because the 8888 pixels were being interpreted as two 565 pixels. The colors were obviously wrong as well. I had missed a critical function call. You must configure the Surface that is being used by EGL using the SurfaceHolder method setFormat. The pixel format needs to be TRANSLUCENT, or more specifically you can use RGBA_8888.
View 2 Replies View RelatedI'm trying to apply an Alpha gradient to a bitmap that I've created from a PNG. I want the image to be opaque at the top and fade to transparent at the bottom. I know this can be done be using getPixels and setPixels for Bitmap and iterating through each row of pixels in the Bitmap and setting the alpha values accordingly, but i was hoping there was a slightly neater way of doing this. I have been looking at the LinearGradient Class and using a Porter Duff transfer mode, but i don't seem to be having much luck with this. It seems that my source image is lost when i apply the Shader to the drawable. Anyone have any tips on how i might apply an alpha gradient to a bitmap?
View 2 Replies View RelatedI have a single-channel PNG file I'd like to use as an alpha mask for Porter-Duff drawing operations.If I load it without any options, the resulting Bitmap has an RGB_565 config, i.e. treated as grayscale.If I set the preferred config to ALPHA_8, it loads it as a grayscale ARGB_8888 instead.How can I convince Android to treat this file as an alpha mask instead of a grayscale image?
mask1 = BitmapFactory.decodeStream(pngStream);
// mask1.getConfig() is now RGB_565
BitmapFactory.Options maskOpts = new BitmapFactory.Options();
maskOpts.inPreferredConfig = Bitmap.Config.ALPHA_8;
mask2 = BitmapFactory.decodeStream(pngStream, null, maskOpts);
// mask2.getConfig() is now ARGB_8888 (the alpha channel is fully opaque)
I've just migrated to 1.5 and a strange bug has occured. I have the following code...
That means I want my image button to have no background, just image. It worked well in sdk 1.1, but now it shows a black rectangle as background. Why can it be and is there another way to remove the background?
I've created a bitmap that I'm overlaying over another bitmap. I'd like to alter the transparency of sections of the overlaid bitmap, revealing the bitmap beneath. I can't find a way to write only to the alpha channel of the overlaid bitmap.
For example, I have a bitmap filled with red pixels, and an alpha that is 255, opaque. A solid red bitmap. How do I draw a circle on this map that would lower the alpha values toward 0, transparent?
How can I get the alpha/opacity of a View after I've animated it? code...
