I have an application which have multiple backgrounds. I would like to cross-fade these backgrounds at a fixed time interval having one background fading out while slowly showing another (kind of like a slideshow). I know how to use the cross-fading effect in xml but the problem is it won't show another image until the active image is totally fading out. I want the transitions to overlap. Please help.
Thanks.
Have a look at this tutorial: http://www.pushing-pixels.org/2011/03/07/android-bits-and-pieces-image-cross-fading.html
see the below link,which solved my problem(cross-fade effect when changing backgrounds of a view):

I want to make my layout white with animation. It got a drawable background. I want to make with some duration smooth animation which makes the background white.
Is it possible? How to make it? Thanks!
Fade-in-Fade-out
The animation that you are asking is Fade-in-Fade-out, which fade out the Drawable background and fade in the white background.
You need to create XML animation. This answer is too broad suggested to see the AndroidHive tutorial about this.
I am developing an android application with very complex design here is how it should look
I want to achieve this star-like design on the lower half of the image. Icons would represent buttons as well.
What I tried before coming here is
https://github.com/ManuelPeinado/ImageLayout
But that didn't work out so well.
Does anyone had similar experience ?
Make an image like that as layout background and place buttons with transparent background wherever u want.
I'm trying to use a listview in my application with a gradient from the bottom.
I do not want to use the gradient in the background, I like to use it in the listview.
To try to explain better, I attached a picture of what I want.
The background will show images that will change.
I searched a lot and made several tests, but without success.
I appreciate any help.
Thanks and regards
Android has something built in for that. It is called fading edge. The two XML properties are android:fadingEdgeLength and android:requiresFadingEdge. If you were hoping to have the image gradient change, I don't think they are dynamic.
I have gridView which has lot of images and on clicking the edit button, I want the images to wobble just like : how to create iphone's wobbling icon effect?. Appreciate any pointers to solve this issue.
You can start off by modeling the wobble effect as a combination of Animations that Android provides. You can then extend an ImageView and use an AnimationSet of this combination of Animations.
You can create an xml that defines how the ImageView will be animated, load the animation in code referencing this xml and then apply it. A brief documentation here.
I'm starting out with Android development, and I'm kind of stuck. Basically, I have a layout with dynamically added ImageViews, and I want to have the ImageViews change their image every once in a while. However, I'd like to add some sort of transition or changing animation, like a flip or a flash.
I don't really know where to even start to look for an answer to this question. Any help is greatly appreciated.
The android framework has this totally covered:
http://developer.android.com/guide/topics/graphics/view-animation.html
Basically, you are looking to define "tween" animations between your drawables (imageviews). After you define your animations you can even define a set of drawables to show one after the other using frame-animation.
Check out the following for all the gory details:
