Flip Animation Listener

EasyFlipView easyFlipView = (EasyFlipView) findViewById(R.id.easyFlipView);
easyFlipView.setOnFlipListener(new EasyFlipView.OnFlipAnimationListener() {
            @Override
            public void onViewFlipCompleted(EasyFlipView flipView, EasyFlipView.FlipState newCurrentSide) 
            {
                
                // ...
                // Your code goes here
                // ...
                
            }
        });

❌ Known Issues

The EasyFlipView doesn't flip when used in RecyclerView. This is because the EasyFlipView uses the onTouch() method to intercept the touch events and flip the view accordingly. One easier solution is to disable the flipOnTouch attribute in XML by this.

app:flipOnTouch="false"

Now, your RecyclerView will scroll but the EasyFlipView will not flip or animate on touch etc. You will have to manually flip the view by calling the method mYourFlipView.flipTheView() inside the adapter or ViewHolder class of the RecyclerView. For example,

public class MyRecyclerViewAdapter extends RecyclerView.Adapter<MyRecyclerViewAdapter.ViewHolder> {

    private List<Object> mData;
    private LayoutInflater mInflater;
    private ItemClickListener mClickListener;

    // data is passed into the constructor
    MyRecyclerViewAdapter(Context context, List<Object> data) {
        this.mInflater = LayoutInflater.from(context);
        this.mData = data;
    }

    // inflates the row layout from xml when needed
    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = mInflater.inflate(R.layout.recyclerview_row, parent, false);
        return new ViewHolder(view);
    }

    // binds the data to the TextView in each row
    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        String textData = (String) mData.get(position);
        holder.myTextView.setText(textData);
    }

    // total number of rows
    @Override
    public int getItemCount() {
        return mData.size();
    }


    // stores and recycles views as they are scrolled off screen
    public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
        TextView myTextView;
	EasyFlipView myEasyFlipView;

        ViewHolder(View itemView) {
            super(itemView);
            myTextView = itemView.findViewById(R.id.tvAnimalName);
	    myEasyFlipView = itemView.findViewById(R.id.myEasyFlipView);
            itemView.setOnClickListener(this);
        }

        @Override
        public void onClick(View view) {
	    myEasyFlipView.flipTheView();
            if (mClickListener != null) {
	    	mClickListener.onItemClick(view, getAdapterPosition());
	    }
        }
    }

    // convenience method for getting data at click position
    String getItem(int id) {
        return mData.get(id);
    }

    // allows clicks events to be caught
    void setClickListener(ItemClickListener itemClickListener) {
        this.mClickListener = itemClickListener;
    }

    // parent activity will implement this method to respond to click events
    public interface ItemClickListener {
        void onItemClick(View view, int position);
    }
}

The EasyFlipView has a strange behaviour when the back and front layouts are a CardView. To workaround it, wrap your CardView in a FrameLayout or other ViewGroup.
