It is a simple gist to realize the UI ANIMATION IN PHOTOSHOP – TUTORIAL #1 provided by Taylor Ling .

Due to shadow and Z-animation, this code can work only on L-devices.

gabrielemariotti

This class provides a simple animator which applies a slide in/out from/to the left animation to item views in the RecyclerView

This code is cloned from DefaultItemAnimator provided by Google, customizing the part highlighted as "Custom implementation".

Example:

   mRecyclerView.setItemAnimator(new SlideInOutLeftDefaultItemAnimator(mRecyclerView));

You can use this class to realize a simple sectioned RecyclerView.Adapter without changing your code.

The RecyclerView should use a LinearLayoutManager. You can use this code also with the TwoWayView with the ListLayoutManager (https://github.com/lucasr/twoway-view)

This is a porting of the class SimpleSectionedListAdapter provided by Google

Example:

gabrielemariotti

public class MyRecyclerViewAdapter extends RecyclerView.Adapter<MyRecyclerView.MyViewHolder>{


    public static class MyViewHolder extends RecyclerView.ViewHolder {

        public MyViewHolder(View view) {
            super(view);
        }
    }

        Toolbar toolbar = (Toolbar)findViewById(R.id.toolbar);
        
        //Title and subtitle
        toolbar.setTitle("MY toolbar");
        toolbar.setSubtitle("Subtitle");

        //Menu
        toolbar.inflateMenu(R.menu.toolbar_menu);

        toolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {
