ways to add 18dpx18dp size image right of title in collapsing toolbar layout? but not in toolbar

问题

I want to put an icon right to title in collapsing tool bar, shown as below

but After collapsing i don't want it to show in tool bar.
i want to hide after collapsing.
i have done some thing. using

collapsingToolbarLayout.setTitle(item.getName()); collapsingToolbarLayout.setForeground(getResources().getDrawable(R.drawable.ic_photo_library_white_24dp));
which look like this.

i am still trying to adjust that image.
but i want to hide that image after collapsing. bez it looks like this.

here is my java code.

private void setToolbar(Product item) {
((AppCompatActivity) getActivity()).setSupportActionBar((productToolBar));

ActionBar actionBar = ((AppCompatActivity) getActivity()).getSupportActionBar();
actionBar.setTitle("");
productToolBar.setNavigationOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        getActivity().onBackPressed();
    }
});
collapsingToolbarLayout.setTitle(item.getName());
collapsingToolbarLayout.setForeground(getResources().getDrawable(R.drawable.ic_photo_library_white_24dp));
collapsingToolbarLayout.set
}

and my xml file.
