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?

View 1 Replies View RelatedI have just swapped from an iPhone 3G to the Desire and am getting stuck whilst familiarising myself with the phone (and making it similar to my iPhone). I have put an unlock password on the phone but it is a pain as it requires alpha and numeric so I want to go back to using the visual password. Problem is I cannot find how to get the phone to swap back to using a visual p/w. Anyone able to help Whilst here is there an app out there to wake up the phone when you press any key and/or have the iPhone keypad pop up to unblock the phone? Other than that it is an impressive bit of kit and better than the iPhone in many ways but flawed in some basic areas such as the pathetic speaker. It nearly went back when I first heard it and seems a surprising oversight given it is obviously aimed at the social end of the market.

Is there anyway to remove that? i will attach screenshot. If I'm changing the Design to any other Theme like "holo glass" it works fine...no overlay, nothing. So there should be a way by decompiling SystemUI or something?

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 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)
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?

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.
View 2 Replies View RelatedThere is Froyo running on an X10, I know its true because its my x10, this is an Alpha version and runs from the SD Card, it is not even a beta version yet but this version is around 90% done, still some things to resolve. This is not a re-flash of the phone it is a dual boot so has not affected the SE base operating system currently installed being 2.1.
The guys at XDA are working on this and if they get it fully resolved then it will become available as an alternative system, if they keep it as dual boot it will never affect your warranty. At all as this installs on your SD Card, there is a thread on the XDA forum but in respect of this forums policy on rooting and other things I wont post the link but searching the XDA forum for x10 Custom Rom will return a number of results so you can find it from there yourself.
If the guys at XDA can do this then SE can, the only thing is XDA are not restricted by International markets and operator restrictions like SE are, if XDA make a custom rom that runs 2.2. From the SD Card then for me its perfect it keeps the phone warranty and software as is and lest you run your own free Froyo version.

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 am drawing some textures with alpha channel, but when they are displayed it looks like the alpha channel is only binary. So a pixel is either transparent or opaque, although in the texture file itself the pixel is half-transparent.
The blending is set up like this:
code:............
The above shows how it should be like, and the below shows how it is:
When applying an alpha value to an imageview, Eclipse displays the view accurately in layout mode. But when exporting to a target device (such as a phone), the alpha appears to be ignored. This impacts developers trying to create fade ins/outs of elements in a widget. Has anyone else come across this issue yet? Not sure if this behavior is by design or by error.

View 15 Replies View RelatedOver the past couple days, it seems like my Weather Channel app hasn't been working properly. When I move to the home screen that has the widget, it will be displaying the wrong temperature and picture (i.e. it might be showing "partly sunny" when it's night time). It just shows the temperature for the last time I opened the app.So, I click on the widget to open the app, and it brings me to one of the screens and it just says "N/A", while a green circle rotates in the upper-right corner. After a few seconds, it finally updates and shows me the current temperature/forecast (whichever screen I was in last).I've never had these problems before, up until the past few days. Usually I would just move over to my other home screen, look at the temp, and move back. It would always be [somewhat] updated by itself (usually every 30-60 minutes it seemed). Now it doesn't update until I actually open the app.Any ideas or suggestions? Or is anyone else having this problem? I am using the Droid Eris. I restarted the phone yesterday, still doing the same thing.
