animation - Move an ImageView to different position in Animated way in Android

Question

I have several ImageViews in a RelativeLayout. now, when user taps any of the ImageView, I want it to be moved to a specified location with subtle animation.

Eg; I have initially set margins for LayoutParams associated with an ImageView as layoutparams1.setMargins(90,70,0,0); and then have it added to the layout.

and when imageview is tapped, I'd like its new location to be 200,200, with animation.

So, is it possible? if yes, then how?

Note that I have both RelativeLayout and all of its child ImageViews created programmatically.

And I'm new to android development so an elaborative answer is expected.

Answer 1

TranslateAnimation animation = new TranslateAnimation(0, 50, 0, 100);
animation.setDuration(1000);
animation.setFillAfter(false);
animation.setAnimationListener(new MyAnimationListener());

imageView.startAnimation(animation);

UPDATE : The problem is that the View is actually still in it's old position. So we have to move it when the animation is finished. To detect when the animation is finished we have to create our own animationListener (inside our activity class):

private class MyAnimationListener implements AnimationListener{

    @Override
    public void onAnimationEnd(Animation animation) {
        imageView.clearAnimation();
        LayoutParams lp = new LayoutParams(imageView.getWidth(), imageView.getHeight());
        lp.setMargins(50, 100, 0, 0);
        imageView.setLayoutParams(lp);
    }

    @Override
    public void onAnimationRepeat(Animation animation) {
    }

    @Override
    public void onAnimationStart(Animation animation) {
    }

}

So the onClickEvent will get fired again at it's new place. The animation will now move it even more down, so you might want to save the x and y in a variable, so that in the onAnimationEnd() you move it not to a fix location.
