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'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 created an application that show around 250 images in ImageView. Images are loaded one after another, 15-30 images per second. Basically the whole thing gives an illusion of a rotating 3D object, at least it should.
The problem is next, app hangs when loading certain images(i.e. I see a few seconds of fluid animation and then animation hangs, jump 10-15 frames(images) ahead and continues. It always happens at the same places in animation cycle.
I though that Android might not have enough resources to handle something like this, so I've resized images to half their size, but it did't help. I've tried buffering images but that did't help either(actually, maybe a little, I think that animation looks a little bit smoother).
And now the weirdest thing. I use the touch screen to allow users to "rotate" the 3D object on those images, and while rotating I again experience those hangs at exactly the same places as with the animation.
All images are in .png format and their size vary from 15kB to 40kB.
I use the following code for the animation:

I'm trying to animate object. I use keyframe animation: I have two vertex buffers (two frames) with vertices of my object - first buffer is for object start state and second for end state. To transform the object I simply use linear interpolation. To make it more clear, please take a look at the code snippet:
CODE:..................
As you can see I actually use one more buffer. vertexBuffer_motion is the one I use to draw my object in intermediate state.
Time for my question. What is the best approach for such keyframe animation on android? Can I somehow avoid (quite time consuming) operations of calculating and copying new state of all vertices to vertexBuffer_motion?
I know I could use VBO but still, I would have to prepare this vertexBuffer_motion and use glBufferData to set data to this VBO (or not?). provide me with some code example showing the best approach for keyframe animation on android?

Is there any way to solve this issue.
I am using a simple frame animation and when I exit and reenter my activity the activity is still referenced in memory.
//This is a sample activity I created to simulate the problem public class MemoryLeakActivity extends Activity {
@Override public void onCreate(final Bundle savedInstanceState) super.onCreate(savedInstanceState);

final Intent i = new Intent(MemoryLeakActivity.this, LeakyActivy.class);
startActivity(i); return super.onKeyDown(keyCode, event);

I want to get an animated text in Android where it should run from left to right on the screen.
Eg: I want to get this text. private static final String QUOTE = "Nobody uses Java anymore. It's this big heavyweight ball and chain.";
running from right to left using animation.
However, this text gets truncated to "Nobody uses Java anymore. It's" in Portrait mode and to "Nobody uses Java anymore. It's this big heavyweight" in landscape mode.
This is the code that I have used:

Is it possible to create a custom button in Android, where the button is idly animating using a frame animation (AnimationDrawable)?
View 1 Replies View RelatedIs there a way to find out the final location of my animated "object" after the animation? Let's say I am animating an ImageView with location in parent as (0,0 - 20,20) using TranslateAnimation and ScaleAnimation over 1 second with setFillAfter(true).
How to I find the final location of this "object" (since the View location itself does not move)? I need to continue the animation from this point based on an user input.
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 ...
In a nut shell, when the app is loaded, it will play a short movie (maybe a few seconds at most @ 12-24fps). I will then have 2 buttons displayed on the screen, and depending on what button is pressed, it I will play another short movie (5-10 seconds). While waiting for the user to make a decision, the movie will be looping.
The movie source is stop-motion photography so it's already chopped up into frames. My question here is if I should use a Frame Animation technique, or if I should use a Movie player for this. All in all perhaps there's less than 100 still frames that make up the stop-motion. I was going to go the Frame Animation route, but I wasn't sure if having so many individual frames would kill the app so I thought I'd post here to see if anyone had any insight.
I have two TranslateAnimation on a TextView and i want them to execute one after other.. but using the below code, only the second one executes.. how can i solve this
CODE:......................
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.

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.

View 1 Replies View RelatedWhen 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?

View 1 Replies View RelatedI'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 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?
