下面是android代码

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) {
        ViewCompat.setTranslationY(mView, mView.getHeight());
        ViewCompat.animate(mView)
                .translationY(0f)
                .setInterpolator(FAST_OUT_SLOW_IN_INTERPOLATOR)
                .setDuration(ANIMATION_DURATION)
                .setListener(new ViewPropertyAnimatorListenerAdapter() {
                    @Override
                    public void onAnimationStart(View view) {
                        mView.animateChildrenIn(ANIMATION_DURATION - ANIMATION_FADE_DURATION,
                                ANIMATION_FADE_DURATION);
                    }

                    @Override
                    public void onAnimationEnd(View view) {
                        onViewShown();
                    }
                }).start();
    }
