I have several ImageViews in a RelativeLayout.
When the user taps any of the ImageViews, I want the ImageView to be moved to a specified location using a subtle animation.
Eg; I have initially set margins for LayoutParams
associated with an ImageView
as layoutparams1.setMargins(90,70,0,0);
and I have then added it to the layout.
When the ImageView is tapped, I'd like its new location to be 200,200
, done 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.

It is better to use ObjectAnimator
which actually moves the ImageView to the new position.
E.g.:
ImageView splash;
@Override
public boolean onTouchEvent(MotionEvent event) {
float tx = event.getX();
float ty = event.getY();
int action = event.getAction();
switch(action) {
case MotionEvent.ACTION_DOWN:
tx = event.getX();
ty = event.getY();
// findViewById(R.id.character).setX(tx-45);
// findViewById(R.id.character).setY(ty-134);
ObjectAnimator animX = ObjectAnimator.ofFloat(splash, "x", tx-45);
ObjectAnimator animY = ObjectAnimator.ofFloat(splash, "y", ty-134);
AnimatorSet animSetXY = new AnimatorSet();
animSetXY.playTogether(animX, animY);
animSetXY.start();
break;
default:
}
return true;
}

you can use this code :)
private void animeView(View imageView){
Handler handler = new Handler();
final int[] deltaX = {50};
final int[] deltaRotation = {45};
handler.postDelayed(new Runnable() {
@Override
public void run() {
imageView.animate().translationX(deltaX[0])
.rotation(deltaRotation[0]).setDuration(1000) ;
deltaX[0] *=-1 ;
deltaRotation[0] *=-1 ;
handler.postDelayed(this , 1000);
}
},1000);
}

you can use this code
imageView.animate().x(80).y(212).setDuration(300);
or
for soft animation you can use this library

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.

In below code I am adding a image view in center on frame layout dynamically. After add I am increase scaling and set alpha to give zoom effect and after complete animation I am just translate my image view one position to another position.
Add image view on framelayout
imgHeart = new ImageView(getBaseContext());
imgHeart.setId(R.id.heartImage);
imgHeart.setImageResource(R.drawable.material_heart_fill_icon);
imgHeart.setLayoutParams(new FrameLayout.LayoutParams(50, 50, Gravity.CENTER));
mainFrameLaout.addView(imgHeart);
Add animation on image view
imgHeart.animate()
.scaleXBy(6)
.scaleYBy(6)
.setDuration(700)
.alpha(2)
.setListener(new Animator.AnimatorListener() {
@Override
public void onAnimationStart(Animator animation) {
}
@Override
public void onAnimationEnd(Animator animation) {
imgHeart.animate()
.scaleXBy(-6f).scaleYBy(-6f)
.alpha(.1f)
.translationX((heigthAndWidth[0] / 2) - minusWidth)
.translationY(-((heigthAndWidth[1] / 2) - minusHeight))
.setDuration(1000)
.setListener(new Animator.AnimatorListener() {
@Override
public void onAnimationStart(Animator animation) {
}
@Override
public void onAnimationEnd(Animator animation) {
// remove image view from framlayout
}
@Override
public void onAnimationCancel(Animator animation) {
}
@Override
public void onAnimationRepeat(Animator animation) {
}
}).start();
}
@Override
public void onAnimationCancel(Animator animation) {
}
@Override
public void onAnimationRepeat(Animator animation) {
}
}).start();
