I am trying to populate a ViewStub with a new view depending on which ImageButton is clicked, but as I just discovered ViewStubs I am not exactly sure how this would work...
e.g. can I provide the ViewStub with different inflatedIds and within the onClick event of a Button inflate the ViewStub by calling a specific inflatedId?
I just ran into a problem, while trying to populate a ViewStub by tapping an ImageButton within a SlidingDrawer (the ViewStub should also be part of the drawer), but all I get is a Force Close Error due to a Null Pointer Exception. As I am using ViewStubs for the first time I am not sure, what may have caused the exception.
This is the code I use to inflate the ViewStub:

I'm working on a game that in some ways is similar to Tetris (imagine a 2D array of colored squares that sometimes move around)
I am trying to animate the individual squares so they will smoothly slide down from coordinate to the next. Since I wanted to use Android's built-in tweening feature, the animation has to apply to the whole View (rather than parts of it). This doesn't work well for me because I only want some of the colored squares to slide down, and the rest of them to stay still.
The (theoretical) solution I came up with to resolve this is to make 2 Views, layered directly on top of each other. The top view is for animating squares when they need to move, and the bottom layer is for the static squares. The animation-layer is transparent until I am ready to animate something. I then simply turn on the colored square in the animation-layer, tween it to the new location, and turn it back off when done. In the same time span, the static-layer just turns squares on and off at the right time to make the whole thing look seamless to the end user.
The proposed solution is just a theory, since I haven't been able to make it work correctly yet. Since I have been having trouble, I was wondering if this is even the best way to solve the problem? Perhaps there is a more elegant solution that I am over looking?
I'm trying to figure out how to animate in and out of Imageviews.
Basically I have a LinearLayout with an ImageView and a Button at the bottom. Everytime the button is pressed, onClick() is invoked and I do
image.setImageResource(imageArray[imageCounter]);
I simply change the image displayed on the ImageView by selecting different photos in the @drawable.
Now I want to put an animation when these imageviews are changed (when button pressed). I used
inAnimation = AnimationUtils.makeInAnimation(this,true);and in onClick() I do image.setImageResource(imageArray[imageCounter]); image.startAnimation(inAnimation);
This works fine too. The new image comes to the screen animated. But how can put an out animation too? It seems only one animation can be assigned with startAnimation().
What is the best way to animate an imageview OUT and then animate another imageview IN? Because I want to change the animation depending on the button pressed, I cannot use ViewFlipper. For example, if I press button_Anim1, current image will slideout from right and the new image will fade in. But if I press button_Anim2, current image will slideout from top and the new image will slidein from left. And so on.
I see that I cannot use two different image.startAnimation() in the onClick() method to make the current image View.INVISIBLE and then make the new image View.VISIBLE.
I saw the Android app "Mobisle Notes Free" implement a really cool ListView, where a row gets moved to the bottom if its checkbox is checked. It's not just a simple refresh, but an actual animation where you see the row travel to the bottom. Does anyone know how to implement this?

Like with AlphaAnimation there is fromAlpha and toAlpha, I need something like ColorAnimation that provides fromColor and toColor. Is there anything like that already?
I installed the HTC Battery widget (downloaded from the Android Market) and notice that while the battery is being charged, there is a visually effective animation that continuously runs.
I always though such animations in widgets were not supported in the SDK.
How is this technically possible?
AK Notepad does this nice little thing where, on displaying the file list, it "unravels" rapidly down the screen. Are they hacking that incredibly manually, or are there simple OS calls to make lists display in various ways?
View 4 Replies View Relatedim currently playing around with a Game that architecture is basically like the example 2d Games like JetBoy / LunarLander and so on. But as things now running (and animating continuously) they have kind of "hiccups" when the GC is running. I have done all i can to allocate as much Objects in front. There is nearly nothing that is created "new" besindes some Strings that are used to set the Score and so on. (TextView doesn't take int's =( - So do you have similar Problems that the GC is "lagging" your 2s game ? any solutions ?
View 12 Replies View RelatedI would like to animate a view I have to appear like it was sliding off the screen to the left, and then sliding back to the screen from the right. I've set the duration of the first and the start Off set of the second as 1000, so the second should start right after the first ends. Instead I get their order reversed and I see my view sliding from right into the screen, and then sliding off the screen to the left. Reversing the animations order didn't do anything. Anyone got a clue why is this happening, and how can I do what I want?

View 3 Replies View RelatedMy app polls a server every 15 seconds to see if there are any new items to display, then downloads the new items and disposes of the old items so that there are always exactly 100 items in the GridView. Unfortunately, this process can be confusing to the user if they see a page of images change without knowing where the items went.
My idea is that there could be some kind of animation (such as the new items being inserted at the top and pushing the older ones down the list) to show what action is happening. Unfortunately, I have no clue how to make this animation happen.
Is my idea even possible? How would I accomplish this?
I want to be able to make an imageview move from point a to b while going through several different views. For example, say I have a table layout, is there any way an imageview can move from the topleft cell to the bottomright cell? Everything I tried seems to indicate that an imageview will only be shown in it's own container - none of it's parents, siblings or children will show it. Is that correct? is there any way around it? like creating an overlay or a transparent canvas on top of the entire thing so I can do it?
View 3 Replies View RelatedThis question was raised a few months ago here: http://groups.google.com/group/android-developers/browse_thread/threa... which suggests that animations cannot be done within an App Widget.
However, I'm sure I've seen some App Widgets animating... I have an App Widget which contains an ImageView. When the user clicks on this Widget I would like the ImageView to continuously rotate until a certain task (think synchronization) completes. This can take anywhere from a few seconds to a few minutes.
I'm trying to animate some text 'zooming out' on top of another view. My code looks something like code...
with animText being invoked in the onDraw() routine of the BoardView. What I'm seeing, however, is the board zooming out, not the text, despite the above calls to setAnimation().
I've looked in the main android docs and at one other example.
I have a view in a fragment. This fragment is within a FrameLayout. I want to animate this view moving outside the fragment borders. However, the view always get clipped when crossing the border. I have tried by setting "android:clipChildren='false'" and android:clipToPadding="false" to everything, but I can't get it to work.
View 2 Replies View RelatedI currently have a view in my Android app and the view is playing a frame animation. I want to animate the view to increase its size to 150%. When I apply a scale animation to it, and the scale animation is completed, I want the view to stay at that new size for the rest of the activities life cycle. Unfortunately right now when the scale up animation is complete, the view snaps back to the original size. How can I get it to keep the new animated tranformation? I'm using myView.startAnimation(AnimationUtils.loadAnimation(mContext,R.anim.scaleUp150));
View 3 Replies View RelatedI'd like to programmatically move between images in the Gallery widget, with animation.
I can change the currently displaying image using the setSelection(int position) method, however that does not animate. Then there's setSelection(int position, bool animate) but the extra boolean on the end there doesn't appear to do anything.
In the source of Gallery it appears that it can handle DPAD key-presses, so a work-around I thought of was to fake the key-presses. Eg.
dispatchKeyEvent(new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_DPAD_LEFT))
However I can't get this working for some reason. Anyone tried this?
I notice three of the widget's methods I'd love to use moveNext(), movePrevious() and scrollToChild() are all private and unusable.
Does anyone know how I might be able to do this?
I need to scroll a MapView programatically to make sure something is in view. I know how many pixels it needs to scroll in each direction. I see methods (in MapController) to animate it to a particular GeoPoint, and to scroll it by pixels without animation. But nothing to do it by pixels, with an animation.
What is an easy way to do this?
I have an app that has a portrait layout. When I rotate my phone into landscape, it loads another layout that is strictly landscape (it is displaying an ImageView). How can I make the transition from portrait to landscape animate smoothly?

For example:
I have a view with a red background color. The background color of the view changes to blue. How can I do a smooth transition between colors?
If this can't be done with views, an alternative will be welcome.
I have a TranslateAnimation that shall animate a LinearLayout (isScrollContainer) to the left and to the right along the x-axis. The animation to the left works and the animation is straight - means that the view is animated horizontally only.
But the animation left to right doesn't work: instead of just moving the view from left to right along the x-axis, the view gets animated into the screen from diagonal lower-right corner. But for the Y parameters I pass fixed identical values.
Here is a flv movie that shows the animation and issue I described: http://tinyurl.com/24n4eac
Code as follows...
there is a very easy and powerful facility to animate the addition and removal of UITableView rows, here's a clip from a youtube video showing the default animation. Note how the surrounding rows collapse onto the deleted row. This animation helps users keep track of what changed in a list and where in the list they were looking at when the data changed.
Since I've been developing on Android I've found no equivalent facility to animate individual rows in a TableView. Calling notifyDataSetChanged() on my Adapter causes the ListView to immediately update its content with new information. I'd like to show a simple animation of a new row pushing in or sliding out when the data changes, but I can't find any documented way to do this. It looks like LayoutAnimationController might hold a key to getting this to work, but when I set a LayoutAnimationController on my ListView (similar to ApiDemo's LayoutAnimation2) and remove elements from my adapter after the list has displayed, the elements disappear immediately instead of getting animated out..................
I'm trying to set the selection of a Gallery in code. I would like to have the Gallery smoothly roll down a few items over the duration of a second or two. At frist glance, it appears that two members would to the trick:Gallery.setAnimationDuration(int animationDurationMillis); Gallery.setSelection(int position, boolean animate); It turns out that the setAnimationDuration only seems to affect the rubber-bandy "return-to-center" effect of the Gallery. In other words, when a gallery comes to rest after a fling, and a gallery item is off center, the animationDurationMillis is used to control the duration of the Gallery centering up the item. However, the value seems to have no effect on the setSelection. No matter what value is set with setAnimationDuration, the Gallery seems to render about 2 or 3 frames when flying between items 1 and 10 for example. Is this working as designed? Does anyone know a trick or workaround that would let me properly animate setSelection? I'd be especially grateful if we could do it with an "Ease Out" effect.

The animated widget is animated "on" the home screen because it slides under other widgets.It is easy to see this behavior if one puts the search box at the bottom of the screen and place some other widgets higher up.I can see this on my N1 and also in the emulator.

View 1 Replies View RelatedImagine I have a toolbar implemented as a horizontal LinearLayout as follows:
[___Button1____] [___Button2___] [___Button3___] [___Button4___]
When someone clicks on Button2, I want the toolbar to change to:
[___Button1____] [___________Button2___________] [___Button3___]
The toolbar should transition from the first state to the second state through a smooth animation. I would like to use a scale animation on Button2, and while that is happening, Button3 and Button 4 should move to the right (while the animation is going on). At the end of the animation (or maybe during), I will fade Button4 out.
Question: How do I achieve an animation of the layout of the toolbar such that only one component (i.e. Button2) is being scaled while the others are not being scaled - the layout is simply updated during the animation of Button2.
I looked at LayoutAnimationController, but it does not appear to allow me to either:
1. specify different animations for the different components, OR
2. indicate that only animate one component and don't animate the others.
I can't scale the entire toolbar because that distorts Button1/3/4 which I don't want.
today i meet the problem.i need technic can control the android machine from server.then i want send data from server to android with no request from android.

Is there something missing from this?
