翻译动画后增加recyclerview的高度（使用ObjectAnimator）

Question

我所做的是点击按钮我隐藏了条形码扫描器，即使用ObjectAnimator进行“Y”翻译。同时，条形码扫描仪下方的recyclerview也将使用ObjectAnimator以“Y”方向平移。动画是唯一的问题，当recylcerview被翻译为“Y”时，它下方有一些空格，我无法填充整个空间。检查下面我使用过的代码。

    //scannerLayout is barcode scanner and recycler view is list
    int height1 = scannerLayout.getHeight(); 
    ObjectAnimator objectAnimator = ofFloat(scannerLayout, "translationY", 0, -1 * (height1));

    objectAnimator.setDuration(1000);
    objectAnimator.start();

    ObjectAnimator objectAnimator1 = ofFloat(recyclerView, "y", barcodeInputBoxHeight); //barcodeInputBoxHeight - is height of edittext which is shown between toolbar and recyalerview 
    objectAnimator1.setDuration(1000);
    objectAnimator1.start();
    objectAnimator1.addListener(new Animator.AnimatorListener() {
        @Override
        public void onAnimationStart(Animator animator) {
        }

        @Override
        public void onAnimationEnd(Animator animator) {
            // here I am doing some other stuff
        }

        @Override
        public void onAnimationCancel(Animator animator) {

        }

        @Override
        public void onAnimationRepeat(Animator animator) {

        }
    });

我尝试在onAnimationEnd上为recyclerview设置新的布局参数，但它没有用。
