 You simply need to use setFillAfter(true).

  Hi,

  I want to move a view from location (x,y) to (x1,y1).
  What is the best way to do it?
  I tried using the following code but it cannot stay at the last point
  (x1,y1),it always translate back:
  TranslateAnimation anim = new TranslateAnimation(
         Animation.RELATIVE_TO_SELF, 0.0f, Animation.RELATIVE_TO_SELF, 0.0f,
         Animation.RELATIVE_TO_SELF, -1.0f, Animation.RELATIVE_TO_SELF, 0.0f);

  anim.setDuration(100);
  anim.setInterpolator(new LinearInterpolator());
  this.startAnimation(anim);

  any suggestions?

  thanks
  Z

2009-04-19 Thread Mike Baroukh 

Thanks for your answer Daniel.

I had some difficulties to understand but finally, it works !
Thanks a lot.

The key point is to display the final result then make an animation that 
start from a negative position to 0.
In my case, it works without having to use post ...

 Hi Mike

 Actually I just got the solution :)
 I was having this problem for a couple of days but just solved it.

 Here is the solution:

 When you want to animate from left to write do this:

 absoluteLayout.post(new SwapViewsDifferent());

 then you have a inner class:

 private final class SwapViewsDifferent implements Runnable {

 public void run() {
 //first it scrolls, so android see the screen.
 absoluteLayout.scrollBy(screenWidth * -1, 0);
 //then the *animation* a little different from
 yours. compare the values
 *Animation **animation* = new 
 TranslateAnimation(*Animation*.ABSOLUTE,
 -screenWidth, 
 *Animation*.ABSOLUTE, 0, *Animation*.ABSOLUTE, 0,
 *Animation*.ABSOLUTE, 0);
 *animation*.setDuration(500);
 *animation*.setFillAfter(false);
 absoluteLayout.startAnimation(*animation*);
 }
 };

 Hope this helps...

 Daniel

 Hi.

 Hi have an absolute layout with pictures.
 Only 2 pictures are show simultaneously. Others are on the layout, 
 but out of view.

 I wan't on user click to show others picture.
 For this, I do an animation to translate the layer.

 For translation from right to left, it works correctly : an other 
 picture come from right progressively while another exit on left side.

 But, for translation from left to right, it don't work : the right 
 picture exits correctly on right side, but left picture only appear 
 on left side at the end of the animation.
 while translating, an empty space appear on left until the end of 
 translation.

 For translating, I make my own animation (not taken from XML because 
 it depends on image size) :

scrollLeft = new TranslateAnimation(0, -(pictoWidth+hspace), 
 0, 0);
scrollLeft.setDuration(300);
scrollLeft.setAnimationListener(this);
scrollRight = new TranslateAnimation(0, (pictoWidth+hspace), 
 0, 0);
scrollRight.setDuration(300);
scrollRight.setAnimationListener(this);

 then, for translating, I do :
layout.startAnimation(scrollRight);

 (I join the widget source in case somebody is interesting on doing 
 the same thing ...)


 Does somebody have any idea how tohave the same effect on left to 
 right scroll than right to left ?

 Thanks in advance.

 Mike

 PS: I can't use filpper because I have to picture visible at the same 
 time and only one disappear at a time.
 It ould be possible but more complicated I thing ...
