                                .translationY(-dpToPx(100))
                                .start();
                        mPrinterCard.setVisibility(GONE);
                        mPrinterCard.setTranslationY(-dpToPx(40));
                        mPrinterCard.setVisibility(View.VISIBLE);
                        mPrinter.clearAnimation();
                        mPrinterKnob.clearAnimation();
                        mPrinterCard.clearAnimation();
                    }

                    @Override
                    public void onAnimationCancel(Animator animation) {

                    }

                    @Override
                    public void onAnimationRepeat(Animator animation) {

                    }
                })
        		.start();


Scale animation:

```xml
<scale xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="300"
    android:fromXScale="0.8"
    android:fromYScale="-1.0"
    android:interpolator="@android:interpolator/accelerate_decelerate"
    android:pivotX="50%"
    android:pivotY="15%"
    android:toXScale="1"
    android:toYScale="1" />

Flipping the card during the scale animation:

mFlipAnimation = AnimationUtils.loadAnimation(viewHolder.itemView.getContext(), R.anim.scale_anim);

        mFlipAnimation.setAnimationListener(new Animation.AnimationListener() {
            @Override
            public void onAnimationStart(Animation animation) {
                Handler handler = new Handler();
                handler.postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        mCardBack.setVisibility(View.VISIBLE);
                        mCardFront.setVisibility(View.GONE);
                    }
                }, 150);
            }

            @Override
            public void onAnimationEnd(Animation animation) {
                mCardFront.clearAnimation();
                mCardBack.clearAnimation();
                ((MainActivity) mActivity).mIsRefreshing = false;
                ((MainActivity) mActivity).resetProgress();
                mCardFront.setVisibility(View.INVISIBLE);
            }

            @Override
            public void onAnimationRepeat(Animation animation) {
            }
        });
