3. Inflate Custom View

mFancyShowCaseView = new FancyShowCaseView.Builder(this)
    .focusOn(view)
    .customView(R.layout.layout_my_custom_view, new OnViewInflateListener() {
        @Override
        public void onViewInflated(View view) {
            view.findViewById(R.id.btn_action_1).setOnClickListener(mClickListener);
        }
    })
    .closeOnTouch(false)
    .build();
mFancyShowCaseView.show();

View.OnClickListener mClickListener = new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        mFancyShowCaseView.hide();
    }
};
