Answer 1

You need to get first reference of it

View logoView = getToolbarLogoView(toolbar);
logoView.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        //logo clicked
    }
});

Using content description we can get View reference. See the comments inline.

public static View getToolbarLogoIcon(Toolbar toolbar){
        //check if contentDescription previously was set
        boolean hadContentDescription = android.text.TextUtils.isEmpty(toolbar.getLogoDescription());
        String contentDescription = String.valueOf(!hadContentDescription ? toolbar.getLogoDescription() : "logoContentDescription");
        toolbar.setLogoDescription(contentDescription);
        ArrayList<View> potentialViews = new ArrayList<View>();
        //find the view based on it's content description, set programatically or with android:contentDescription
        toolbar.findViewsWithText(potentialViews,contentDescription, View.FIND_VIEWS_WITH_CONTENT_DESCRIPTION);
        //Nav icon is always instantiated at this point because calling setLogoDescription ensures its existence 
        View logoIcon = null;
        if(potentialViews.size() > 0){
            logoIcon = potentialViews.get(0);
        }
        //Clear content description if not previously present
        if(hadContentDescription)
            toolbar.setLogoDescription(null);
        return logoIcon;
    }
