android - How to implement the "parent-to-child" navigational transition as prescribed by Material Design

Question

Google's Material Design guidelines prescribe the following transition for "parent-to-child" transitions when the parent consists of a list. (Material Design Guidelines)

How do I provide such a transition? I'm unaware of any inbuilt transition provided to make this possible.

Answer 1

One option is to use ActivityOptionsCompat.makeScaleUpAnimation

Activity activity = getActivity();
Intent intent = new Intent(activity, OtherActivity.class);
Bundle options = ActivityOptionsCompat.makeScaleUpAnimation(
    sourceView, 0, 0, sourceView.getWidth(), sourceView.getHeight()).toBundle();

ActivityCompat.startActivity(activity, intent, options);

This will cause the new activity to expand vertically and horizontally outwards from your sourceView
