浮动的动作按钮没有完全显示在一个片段里面

I am using FAB button along with RecyclerView in a Fragment. This Fragment is an instance of a TabViewPager. I am having a issue with the FAB button. I have placed the RecyclerView and the fab button inside a FrameLayout, where the FAB buttton is positioned bottom right. Now the problem that I am facing is the FAB button is not fully visible. Its half of the portion is hidden as shown in the screenshot below. Can any one help me to solve this issue. Thanks in advance. I am using FAB button along with RecyclerView i
