Question

好的，所以我以编程方式为我的布局添加视图，然后为它们设置动画，视图似乎正确添加但是当我开始动画时，它似乎无法在这里工作是代码：

                Random random = new Random();
            final ImageView imageView = new ImageView(getApplicationContext());
            final ViewGroup vg = (ViewGroup) animationLayout;

            RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
            //params.topMargin = screenHeight;
            params.leftMargin = random.nextInt(screenWidth);

            vg.addView(imageView,params);

            imageView.setImageResource(R.drawable.musical);
            imageView.setColorFilter(getResources().getColor(R.color.colorPrimary));
            float randomSize = random.nextFloat() * (1.5f - 0.5f) + 0.5f;
            imageView.setScaleX(randomSize);
            imageView.setScaleY(randomSize);


            ObjectAnimator animator = ObjectAnimator.ofInt(imageView, "translationY",0, -screenWidth);
            animator.setDuration(15000);
            animator.setInterpolator(new LinearInterpolator());
            animator.addListener(new Animator.AnimatorListener() {
                @Override
                public void onAnimationStart(Animator animator) {

                }

                @Override
                public void onAnimationEnd(Animator animator) {
                    Log.e("removed", "true");
                    vg.removeView(imageView);
                }

                @Override
                public void onAnimationCancel(Animator animator) {

                }

                @Override
                public void onAnimationRepeat(Animator animator) {

                }
            });
            animator.start();

什么可能导致动画不起作用？动画结束后视图会被删除，所以我不明白

确定答案看起来像我使用ObjectAnimator.ofInt()而不是ObjectAnimator.ofFloat()

动画添加动态视图
