Android translate animation - permanently move View to new position using AnimationListener

Question

I have android translate Animation  I have an ImageView with random generated position  next1  next2   I am calling void every 3 seconds  It generates new position of the View and then make animation and move View to destination position  Translate animation has  AnimationListener implemented  When the animation finish   I move View permanently to the new position  in OnAnimationEnd   My problem is that animation position does not correspond with setting layoutParams positions  When animation end  it makes jump to a new position  which is about 50-100 pixels far  I think the positions should be the same because I use same values  next1  next2  in both situations  Please can you show me the way to find sollution      FrameLayout LayoutParams pozice motyl    FrameLayout LayoutParams   pozadi motyl getLayoutParams                    TranslateAnimation anim   new TranslateAnimation Animation ABSOLUTE pozice motyl leftMargin  Animation ABSOLUTE  next1  Animation ABSOLUTE  pozice motyl topMargin  Animation ABSOLUTE  next2               anim setDuration 1000               anim setFillAfter true               anim setFillEnabled true                anim setAnimationListener new Animation AnimationListener                      Override                 public void onAnimationStart Animation animation                                        Override                 public void onAnimationEnd Animation animation                            FrameLayout LayoutParams layoutParams   new FrameLayout LayoutParams 100  100                        layoutParams leftMargin    int  next1                       layoutParams topMargin    int  next2                       pozadi motyl setLayoutParams layoutParams                                        Override                 public void onAnimationRepeat Animation animation                                                    pozadi motyl startAnimation anim     Here is XML layout    lt FrameLayout xmlns android  http   schemas android com apk res android      xmlns tools  http   schemas android com tools      xmlns ads  http   schemas android com apk lib com google ads      android layout width  fill parent      android layout height  fill parent       android id    id pozadi0      android gravity  center vertical      android layout gravity  center vertical                android background   drawable pozadi2       gt      lt LinearLayout android id    id pozadi motyl          android layout width  wrap content          android layout height  wrap content           gt      lt ImageView android id    id obrazek motyl               android src   drawable motyl               android layout width  100dip               android layout height  100dip                             gt       lt  LinearLayout gt     lt LinearLayout  android orientation  vertical  android layout width  fill parent  android layout height  fill parent   gt    lt RelativeLayout android id    id obrazek pozadi0  android layout width  fill parent  android layout height  fill parent   gt       lt ImageView android id    id zaba obrazek0  android src   drawable zaba obrazek  android layout width  wrap content  android layout height  wrap content  android layout alignParentBottom  true  android layout centerInParent  true    gt    lt  RelativeLayout gt      lt  LinearLayout gt     lt LinearLayout android layout width  fill parent  android layout height  fill parent    gt    lt cz zaba Spojnice   android layout width  fill parent            android layout height  fill parent     gt    lt  LinearLayout gt   lt  FrameLayout gt

I usually prefer to work with deltas in translate animation, since it avoids a lot of confusion.

Try this out, see if it works for you:

TranslateAnimation anim = new TranslateAnimation(0, amountToMoveRight, 0, amountToMoveDown);
anim.setDuration(1000);

anim.setAnimationListener(new TranslateAnimation.AnimationListener() {

    @Override
    public void onAnimationStart(Animation animation) { }

    @Override
    public void onAnimationRepeat(Animation animation) { }

    @Override
    public void onAnimationEnd(Animation animation) 
    {
        FrameLayout.LayoutParams params = (FrameLayout.LayoutParams)view.getLayoutParams();
        params.topMargin += amountToMoveDown;
        params.leftMargin += amountToMoveRight;
        view.setLayoutParams(params);
    }
});

view.startAnimation(anim);

Make sure to make amountToMoveRight / amountToMoveDown final

Hope this helps :)

Just Do like this view animate                translationY -  root height -  view height     2  toFloat                 setInterpolator AccelerateInterpolator    duration   1500  Here  view is your View which is animating from its origin position  root is root View of your XML file  Calculation inside translationY is made for moving your view to the top but keeping it inside the screen  otherwise  it will go partially outside of the screen if you keep its value 0

This is what worked for me perfectly -     slide the view from its current position to below itself public void slideUp final View view  final View llDomestic        ObjectAnimator animation   ObjectAnimator ofFloat view   translationY  0f       animation setDuration 100       llDomestic setVisibility View GONE       animation start           slide the view from below itself to the current position public void slideDown View view View llDomestic       llDomestic setVisibility View VISIBLE       ObjectAnimator animation   ObjectAnimator ofFloat view   translationY     0f       animation setDuration 100       animation start        llDomestic   The view which you want to hide  view  The view which you want to move down or up

You can try this way -   ObjectAnimator ofFloat view   translationX   100f  apply       duration   2000     start       Note - view is your view where you want animation

You should rather use ViewPropertyAnimator  This animates the view to its future position and you don t need to force any layout params on the view after the animation ends  And it s rather simple   myView animate   x 50f  y 100f    myView animate   translateX pixelInScreen        Note  This pixel is not relative to the view  This pixel is the pixel   position in the screen
