动画动态添加的视图

Question

好的，所以我以编程方式将视图添加到我的布局中，然后对其进行动画处理，视图似乎添加正确，但是当我启动动画时，它似乎不起作用这里是代码：

                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工作？动画结束后视图会被删除所以我不明白

Answer 1

好的，发现答案好像我使用的是ObjectAnimator.ofInt() 而不是ObjectAnimator.ofFloat()
