     {
           @Override

               Iv1.startAnimation(animFadein1);
               Iv2.startAnimation(animFadein2);
               |Iv3.startAnimation(animFadein3);
               Iv4.startAnimation(animFadein4);

               return true; 
           }
       });
   
       floatingActionButton.setOnTouchListener(new OnTouchListener() {
           @Override
           public boolean onTouch(View v, MotionEvent event) {
               switch(event.getAction()){
                   case MotionEvent.ACTION_UP:
                   {
                       Toast.makeText(getApplicationContext(), "Rlesed", Toast.LENGTH_SHORT).show();
   
                       return true; 
                   }
               }
               return false;
           }
       });

请看示例图片：

topleft.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">;
    <translate
        android:duration="500"
        android:fromXDelta="-5%"
        android:fromYDelta="-5%"
        android:toXDelta="0%"
        android:toYDelta="00%"
        android:zAdjustment="bottom"></translate>
</set>

topright.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">;
    <translate
        android:duration="500"
        android:fromXDelta="5%"
        android:fromYDelta="-5%"
        android:toXDelta="0%"
        android:toYDelta="00%"
        android:zAdjustment="bottom"></translate>
</set>

Answer 1

我会这样用ObjectAnimator这样做：

val animatorSet = new AnimatorSet()
val moveDownAnimator = ObjectAnimator.ofFloat(imageView, View.TRANSLATION_Y, deltaY) // move down
val moveUpAnimator = ObjectAnimator.ofFloat(anotherImageView, View.TRANSLATION_Y, -deltaY) // move up
...
animatorSet.playTogether(moveDownAnimator, moveUpAnimator,...);
animatorSet.setDuration(ANIMATION_DURATION);
animatorSet.start();

与发布类似：

val releaseAnimator = ObjectAnimator.ofFloat(imageView, View.TRANSLATION_Y, 0);
