Android :: Animation.start - Or Animation.startNow - Does Not Start The Animation Immediately
Aug 30, 2010
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'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?

Is it possible to disactive the animation between activities provided to user with cupcake 1.5? User can set a preference with 1.5 to set animation on activity launch. I would like disactive these animations inside my app containing different activities.

- 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.

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?

I have a static background image, and a foreground that needs to be animated. I tried a couple different approaches but the animation seemed choppy. One thing I did was having 2 different views, constantly calling invalidate() on the foreground view. Another was to have only 1 surfaceview, redrawing the background image and the foreground on each step of the animation.
While a surfaceview offers an optimal way to do heavy-duty animation, having to redraw the background every time kills the performance. Neither produced a smooth animation. What is the best way to perform this kind of animation - static background and animated foreground?

I am working on some animation application where i am trying to apply 2 kind of animation on the TextView.
During onCreate() of the activity I am rotating it by 45 degrees & on onTouch() event i want it to translate & then rotate it to proper shape.
But on onTouch it comes to normal shape & then translate & then again rotate.
How to keep old state of the TextView?

I'm trying to perform a simple animation, but it seems quite choppy. This is it: Animation anim = new Translate Animation(0,0,-50,0); anim.set Duration(500); anim.setInterpolator(new LinearInterpolator()); myLinearLayout.set Animation(anim);the animation does what it's supposed to do, just very choppy - is there any reason why it's so slow? The linear layout I'm applying it to is pretty simple, just has a few children.

I have doubts while doing some 2D Graphics and animation. Here is what i have done and what i want to do further: An application starts with a 2D object [ball] rotating and execising in a particular fashion, and after a particular point in time the object [ball] scrolls out of vision. After this point i want to invoke a new activity with a different UI. I m stuck up while trying to transit from this View to a new activity.

When writing an App Widget based on Cupcake, I create a remote view like this:
views = new RemoteViews(context.getPackageName(), R.layout.widget_loading);
However, the widget_loading.xml contains <ViewAnimator>. The ViewAnimator don't have @RemoteView tag, so it's can not be inflated in remote view.
To fix this, I define a MyViewAnimator (which most likely the ViewAnimator in android) with @RemoteView tag in my project. Then use MyViewAnimator class in the layout xml file. But it failed, there was a exception that class loader cann't find MyViewAnimator class.
So the problem is: how to use any animation in the remote view? Is it possible adding some visual effects on app widget?

I have a widget that periodically updates itself (hourly) to display top result of search query. I would like to extend it so it captures several top results and then loops through these. The best example would be Genie News and Weather widget for which I was unable to find a source code. What would be a good way to implement the animation? I'm thinking ViewAnimator + timer, but is there maybe a better way, say FrameLayout + alerts? I'm already using AlertManager to periodically pull search results for the widget How bad such arraignment would affect phone's battery life?

I need to create an animation - Flip a view and show another one. The width of currently shown view is decreased slowly to zero and after that the width of the view-to-be-shown must be increased from zero. During this time, the height goes from the currently-shown-height to slightly-decreased-height and back again.

I've met a problem with animation when tried to make a View to perform the animation which should cross 2 layouts, e.g. make a translate animation so a view could move down to the TableRow below. This trick works fine when i try to move a view within a single TableRow but not when i try to move it up or down. I've also discovered that if i create a single RelativeLayout and apply the same animation there, it works fine, but i can't arrange all the components i need on the screen. Could anybody please provide me any hints about it?

I am doing an application-infinitely rotating 3D cylinder in openGl.The speed varies with finger touch but wen i reduce the speed,i can see flickering happening in animation towards right and left.Initialy I thought it is because of the linked list im updating but found out there is no such problem with my linked list .I'm using a thread here for a small delay after each 30 degree rotation drawing.I cant do it widout the thread coz i need a sleep or a delay after each 30 degree drawing,if i remove the thread and implement the code in thread inside my onDraw frame, the curvature rotation itself goes and it appears that images are just left shifting n right shifting coz the sleep is not getting identified in onDraw frame.So i cant implement my logic here widout using thread..so thread is a must in my logic but i guess the flickering is due to my thread...Is the flickering issue during animation because of the thread?please do help me with this flickering issue......
This is d thread part im using in my code.........

I would like to obtain the transformation matrix of an animation to calculate the position of the view that was animated.It seems the Animation class has a method called getTransformation that can be used to obtain the transformation applied to the view.However, if I use getTransformation before starting the animation I obtain the identity matrix.The program enters an infite loop because getTransformation seems to trigger onAnimationEnd (why?).How should I use getTransformation to obtain the transformation matrix of an animation? Is there another way to do this?

can someone tell me if I can change the activity animation by applying a theme?I know the change will not be global, but is it even possible to make the change to be applied within my own app? For example, if i have an app that does not want to standard slide in/out animation on start/ exit, is it possible to change them?

I want dont want the activity animation that comes by default when we start a new activity (i.e. the right to left scrolling effect to new activity view) so i googled a bit and found a flag FLAG_ACTIVITY_NO_ANIMATION in the Intent class also i applied that flag to my intent via the setflags() method but somehow i still see the activity animation when a new actvity is launced ( i am developing in android 2.1 update).

I'd like to show a large green arrow in front of all other views when the user clicks a button. The arrow should fade in, stay there for 1-2 seconds and fade out again. How would I go about programming this? I've looked at the animation examples but would like to confirm the way forward before I dive into programming something that won't work :-):
Draw the arrow-image as a bitmap, immediately make it invisible Fade it in ("alpha"-change animation)
Let it stay for 2 seconds Fade it out (again, "alpha"-change animation)
Is this correct, or would you suggest something else?
