Android :: Blinking Image Using Alpha Fade Animation
Oct 11, 2010
I'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'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?

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 ?

My app's main screen is a listview in portrait mode. When it is in landscape orientation it switches to an ImageView. I want to be able to animate a fading transition when I switch orientations. How can I go about doing this?

CM7 unlock screen fade out animation?
I was using CM7 passion (nexus one) nightly #237 and I've learned that everytime I unlock my phone using CM7 lockscreen, it auto fades out into the homescreen.
But yesterday I was flashing to the latest update #253. I could not get back the little fade out animation after you unlock the CM7 lockscreen. Any trick to enable that?

I use http://stackoverflow.com/questions/541966/android-how-do-i-do-a-lazy-load-of-images-in-listview/3068012#3068012 to load images in a ListView and a GridView. It works but the images are loaded form bpttom to top. How to fix that?
Bonus Question: Can I use a loading animation in a image view while the real image is loaded? Right now it's just a default image.

I have a custom drawable, where I draw a base bitmap image, then part of an image over the top of that that is clipped to a certain rectangle. For the overlayed image, I am trying to blur the edges, and I thought I could accomplish that using a BlurMaskFilter, however, I'm not seeing any blurring occurring.
Here is the content of the draw method from my Drawable class.The result is almost correct, except the overlay image is not being blurred.
m_paint = new Paint();
m_blurPaint = new Paint();
m_blurPaint.SetMaskFilter(new BlurMaskFilter(blurRadius, BlurMaskFilter.Blur.Outer));
[code]...
This code is written in C# using Xamarin, so I realize that some things are slightly different, but the overall methods will be the same.

I have implemented an activity that retrieves data from a web service and display it in the AutoCompleteTextView. This has been working quite well.I'm interested in displaying a spinning animation while the data is being retrieved (The same effect like the Quick Search Box) I try to figure out how the QSB is doing it (10x Open Source!) but couldn't find any place where the spinner image is being put/set/drawn onto the EditText control.

- TEXT VIEW -' SLIDE DRAWER image
I have a layout like this above textview and an image that slides down after clicking the text view. I have looked at translate animation but the issue is I want the image to start from the bottom of text view and gradually get into its full view. Translate animation doesn't let me start from behind the textview so that it can appear slowly and coming out at the bottom of text view and expanding to its fullview. I have linear layout now with textview and imageview.

I am trying to put a custom boot animation on my moto droid 1. I have root I have done it before and I am using froyo. My big problem now is that I tried putting a different one I downloaded on and it worked. So I need someone to tell me whats wrong with the one I made, because I am out of ideas. I have compared size, resolution, ppi, bit depth but for some reason my images are way bigger files. The sequence was created by using virtualdub to clip a section of an animated short, then exporting an image sequence as png.
But I've fed the images through gimp and an image resizer. The frames are only some of them because I went through deleting every other frame a few times to cut down on the total size. The file is too big to attach here so i put it on my web space at:
http://www.freaksed.com/stuff/bootanimation.zip
I am using the patch that lets me put the files in datalocal and be named bootanimation.zip. it works I've tried with other animations like I said.

I have an Android application that makes use of TTS (Text to speech) API. Everything is working perfectly, but now i want to fade in/out or even stop music (in case user is playing music with prebuilt Music Player), when application speaks a text. Right now, i think both music and TTS messages are played on the same stream (MUSIC), and it can be difficult to understand the voice messages.It does stop the music,but doesn't come back when the text is spoken, so i didn't achieve the goal.

I 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 ...

I 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.
