Get location of object when animation is complete in android - android

Is 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.

hook up the AnimationStopped event and then request a location from the animated view.

I figured it out - use getTransformation on the Animation and apply the Matrix to the initial Rectangle, to obtain the final destination.

Is there a way to animate the HERE Android SDK marker movement on the map?

I am trying to animate MapMarker object movement between two point on the map.
This is line that sets new position but without animation.
marker.setCoordinate(new GeoCoordinate(lat, lon));
I found this https://developers.google.com/maps/documentation/javascript/reference/marker?hl=en#Marker.setAnimation but it looks like continuous animation
Maybe you can create manually your own animation with PropertyAnimator or something else and calculating progress of changing position

Get coordinates of imageview during animation android

I am trying make an animation of an imageView from left to right and get it back from right to left but I also want to get the position of the imageview while its animation from the following code. I want to use the coordinates from origin to display in my app. Please tell me how to do this. Following is the code I am using to animate and move position of imageview.
Animation anx = new TranslateAnimation(0,100,0, 0);
anx.setDuration(2000);
anx.setFillAfter(true);
myImage.startAnimation(anx);
Is there a function like getX() and getY() to get position.
Have u tried to set animation listener and starting a runnable when the animation starts to check the image getx , gety every milliseconds u want and stop it after the animation ends

translate animation from the where the last translate animation stopped

I have a translate animation of an image from location1 to location2. However at any time during the animation, if a user click a button then I want to apply another translate animation from where the image at to location3 (even if the animation has not finished). Any way I can do that?
Thanks
TranslateAnimation translate = new TranslateAnimation(0, mDestLoc[0]-mSrcLoc[0], 0, mDestLoc[1]-mSrcLoc[1]);
translate.setFillAfter(true);
translate.setDuration(getDuration());
ball.startAnimation(translate);
void onbuttonClicked(){
// stop previous animation and translate image to location 3 "From where it stopped"
}
why don't you use ObjectAnimators?
You can create an animator for a particular target(or obtain the view one through animate() if you're running on a version greater-equal API level 12) and then translate, resize, fade,... your object.
If for some particular reasons the first animation is cancelled, you can call cancel and then the view will persist the current status. Then, if you create another animator based on the current values you should be able to easily perform another animation.

How do i animate an image in android so it follows a path made of several coordinate?

I found out that the movement of an image between two point can be achieved with this simple code:
ImageView image_to_move = (ImageView) findViewById(R.id.image_to_move);
TranslateAnimation animation = new TranslateAnimation(50, 100, 50, 100);
animation.setDuration(5000);
image_to_move.startAnimation(animation);
The image is an ImageView set initially in position (0,0) inside a FrameLayout and the code move it from the point (50,50) to (100,100).
What if i have to move it on a path, made of several point, in the form of absolute coordinate (x,y)? For example, move from (50,50) to (75,75) then to (100,100)
There's a way to pass to the translating function an array of coordinate or i have simply to iterate the animation for every couple of points?
Btw, i saw that if i don't initially locate the image in (0,0) the function moves the image in a weird way, like the coordinate i give are not read as absolute. Am i missing something?
EDIT: The last thing happens when i pass as parameters to the TranslateAnimation something like "n92.getX()" where n92 is a button on my frame layout, from which position i want the animation to start.
DETAIL: Just to understand better the problem: I am implementing the animation of a point moving on a map, to show the user how to get from one point to another of a map. That's why i have absolute coordinate (the reachable points) that must be followed (you can't arrive from one point to another without following a precise path on the map)
to do so you need to Calculate the position on a quadratic bezier curve. try this answer it might be work for you

Reversing view animation on Android?

So if I have a translation animation like
Animation anim = new TranslateAnimation(0, 0, 0, OFFSET);
anim.setDuration(1000L);
anim.setAnimationListener(listener);
anim.setFillAfter(true);
and I apply this to a textswitcher so that given a offset, the textswitcher will move from a location, A, up or down.
My textswitcher will stay at a given location, B, after the animation due to the setfillafter. How can I then from that location, B, reverse the animation and go back to location, A?
The Overall Question
So I'm translating a textswitcher down and then up, but of course, setfillafter only translates the bitmap of the view and not the view itself, so this may not be the best approach. I've also tried to do an animation and then offset of the view, but that looks glitchy. So basically, I want a view(textswitcher) which a swipe/fling down will move it down and touching(onClick) it when it's down will move it back up (same animation reversed). How can I do this?
I know how to do the swipe/fling and onClick stuff, just not how to implement the correct animation.
Perhaps you may want to consider adding an on touch listener to see where you touched it last, If above move up with a constant animation. This is if im understanding the question correctly.
