I have totally 7 buttons at bottom of screen as like menus. In that, 4 buttons is visible when i click that 4th button first 3 buttons are move away from right to left and next 3 buttons are come into that place and vice versa. What type of animation should i use for this os is it possible to use TranslateAnimation or how to use ObjectAnimator
Give any suggestions.
Note that a view animation (like translate animation), is not going to move the actual button mechanism, just where it is visually drawn on the screen. Ie. when your buttons move, the area to click them will still be in the original position. If you want your actual object to move then a property animation (value animator, object animator, or view property animator) is the best choice.
You can read more about property animation and how to use them here: http://developer.android.com/guide/topics/graphics/prop-animation.html

I have several EditText views that I want to animate a change in text of in succession one after the other. I would like to implement a slide out/in animation (old text slides down below and new text slides in from above).
I think this would require setting an animation listener to the slide down animation so that the slide in animation can be started when the slide down animation ends. However it seems the animation listener is attached to the animation itself whereas I need to know when an animation has ended on a particular EditText and to set the correct new text on the EditText.
Since the actual animation for each EditText will be the same, is there a way to do this with just the one animation object (i.e. Animation slideDown) or do I have to create a separate animation objects for each field (e.g. Animation slideDown1, slideDown2, slideDown3, etc)?
I've created a RelativeLayout that contain 4 buttons positioned like a circle. I've given rotate animation to the layout, also OnClickListeners on these buttons. But when i run the code the OnClickListener works only from the button's initial position.
That is, suppose the layout rotate 90 degrees, the button comes to a new position. But clicking on that position doesnt do any thing instead I need to click at the position where it was initially, to activate ONClickListener for that button.
Is there any way to set OnClickListener for the same position as it is displayed?

use property animation instead of view animation according to google doc
view animation system is that it only modified where the View was drawn, and not the actual View itself. For instance, if you animated a button to move across the screen, the button draws correctly, but the actual location where you can click the button does not change, so you have to implement your own logic to handle this.

I am making a game in which I have 5 buttons, looking like clouds, falling from the "sky".
That means that when my activity starts, 'clouds' cannot be seen, since the marginTop is set to -100dp.
From that position they start falling down untill they get lost on the bottom side of the screen.
The thing is, I need those buttons to be clickable, during the process of animation.
So far, I found some documentation about how I can make the buttons clickable AFTER the animation ends. But I don't need that. I need to be able to click on the buttons through the animation time itself.
NOTE: I need something that works with versions before 3.0.
Anybody has any link to documentation or some example or anything ?
After doing some research, I found out that there are two types of animations:
View Animation and Property Animation.
The view animation can only animate View objects. It also lack a variety of animations, since it can do only stuff as scale, rotate, move... It cannot change background color, for example.
Also, the disadvantage of the View Animation is that it only change the position of where the View object is DRAWN. Physically, it still stays in the same position.
That's why the button is un-clickable, after the View Animation is finished upon it.
Property Animation, in the other hand, can animate both View and non-View objects and it doesn't have constraints as the View Animation.
When objects are moved, for example, with the property animation, they are not just drawn on some other position on the screen, but they are actually MOVED there.
Now, Property Animation is a lot more complex to write than the View Animation, so if you don't really need all the advantages of the Property Animation, it is suggested to use View Animation.

You can change the buttons to imageViews and then do
imageView.setOnClickListener(myListener)
then set myListener to do whatever you previously wanted to happen on the buttons onClick. Your activity will have to implement OnClickListener
Added bonus: you can make the images look like clouds :)
I started with a simple animation on button,
I am successful to an extent,
The problem i am facing is, I am able to animate the button but the position of listener,
Even after button is animated the clickable area is not animated , It is resting at the original postion
Could some one help me with an useful code snippet or suggestion
Regards
Android animations can not change the layout of buttons or view in general. Only their image will appear to move, but they will stay in the same place. After the animation is finished, get the Layout parameters through View.getLayoutParams() and change them.
I've got an absolute layout. In that layout is a custom view that takes up the left 3rd of the screen. I put a button in the layout that I want to cause the custom view to slide on and off of the screen. I've tried using animation resources (translates... "slidein" and "slideout") and the function startAnimation on the custom view, but I can't get the behavior I am looking for.
OK... I start with the custom view visible and in onCreate I find the view and animate it off screen using my slideout animation. That works fine. I figured out that I need to set "fillAfter" in the animation so that the custom view stays off screen.
Now, when I press my button I want to cause the custom view to slide back on the screen, so I trigger my slidein animation using startAnimation again but with slidein. BUT... that causes the view to first jump back to its original position AND THEN slide to the right... causing it to finish in the middle of the screen.
How do I get the animation to use the view's current position as the animation starting position, not its original position?
Thanks
I also experienced the flicker described in this question. My solution was to use the improved Honeycomb animation APIs. There is a convenient library that ports these all the way back to Android 1.0:
http://nineoldandroids.com/
For more on Honeycomb Animation APIs see:
http://android-developers.blogspot.com/2011/02/animation-in-honeycomb.html
In my case I had 2 overlapped LinearLayouts inside a RelativeLayout. I wanted to slide the top LinearLayout off the screen and reveal the bottom LinearLayout below. Then I wanted to slide to top LinearLayout back on screen to its original position so the top layout covered the bottom layout again. Using the old animation APIs I was seeing a flicker before the second animation (offscreen -> onscreen) was starting.
With the new APIs this task turned out to be trivial:
// Slide out (add to button handler)
ObjectAnimator.ofFloat(mTopLayout, "translationY", mTopLayout.getHeight()).start();
// Slide back in (add to button handler)
ObjectAnimator.ofFloat(mTopLayout, "translationY", 0).start();
The Honeycomb Animation APIs actually move objects around on the screen (rather than pretending to move them like the older animation APIs), so there is no need to fool around with filleAfter, fillBefore, etc.
Look into setting the fillAfter property to keep the end animation state
