Disable onClicklistner while other touch listner is active

I am trying to implement UI like google keep. In the main layout there is frame layout in which there is a FAM(Floating Actions Menu) and a blackshadow view which is visible when FAM is expanded.

What i want is that when i touch the shadow view it should Collapse the FAM. To do that i have implemented onTouchlistner on shadowview.

shadowview.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if(fam.isExpanded()){
                fam.collapse();
            }
            return false;
        }
    });

But what happens is that when i touch the area with MyCardGridView's card (Which open's another activity) open's another activity. Which should not happen.
