Before Enabling view

After enabling and disabling the view

Answer 1

View.GONE This view is invisible, and it doesn't take any space for layout purposes.

View.INVISIBLE This view is invisible, but it still takes up space for layout purposes.

btn_disable.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            textView.setVisibility(View.GONE);
        }
    });
