我试图模仿动画和下面的浮动动作按钮的颜色变化.

浮动操作按钮的工作方式是白色关闭,蓝色打开.

但是,我没有成功完成动画和改变颜色.

这些都是我尝试这样做的,因为你可以看到我已经评论了我尝试过的所有不同方法.

这是我的代码:

    @SuppressWarnings("unused")
    @OnClick(R.id.fabMovieFavourite)
    public void addMovieFavourite(View view) {
 /*       final Animator animator = AnimatorInflater.loadAnimator(getActivity(), R.animator.add_favourite_movie);
        animator.setTarget(view);)
        animator.start();
 */
/*
        AnimatorSet animatorSet = new AnimatorSet();
        PropertyValuesHolder propertyValuesHolderX = PropertyValuesHolder.ofFloat(View.SCALE_X, 1.1f);
        PropertyValuesHolder propertyValuesHolderY = PropertyValuesHolder.ofFloat(View.SCALE_Y, 1.1f);
        ObjectAnimator objectAnimator = ObjectAnimator.ofPropertyValuesHolder(view, propertyValuesHolderX, propertyValuesHolderY);
        objectAnimator.setDuration(300);
        objectAnimator.setInterpolator(new OvershootInterpolator(10f));
*/

        /*
        objectAnimator.setRepeatCount(1);
        objectAnimator.setRepeatMode(ObjectAnimator.REVERSE);
*/

/*
        PropertyValuesHolder propertyValuesHolderX2 = PropertyValuesHolder.ofFloat(View.SCALE_X, 0.9f);
        PropertyValuesHolder propertyValuesHolderY2 = PropertyValuesHolder.ofFloat(View.SCALE_Y, 0.9f);
        ObjectAnimator objectAnimator2 = ObjectAnimator.ofPropertyValuesHolder(view, propertyValuesHolderX2, propertyValuesHolderY2);
        objectAnimator.setDuration(300);
        objectAnimator2.setInterpolator(new OvershootInterpolator(10f));

        animatorSet.playSequentially(objectAnimator, objectAnimator2);
        objectAnimator.start();
*/

      //  view.BackgroundTintList(ContextCompat.getColorStateList(getContext(), R.color.primary));
        //view.setBackgroundColor(ContextCompat.getColor(getActivity(), …
