Floating action buttonが実装できません。。。

FragmentViewPagerの上のFragmentのListViewの上に重ねてFloating action buttonを置きたいんです。。

FragmentViewPagerはAppCompatActivityにおいてあり、テーマはTheme.AppCompat.Light.NoActionBarになっています。

Buttonを配置する時点でエラーが出てしまったのでボタンに処理を設定することはできていません

リソースファイル上でFloating action buttonを設置しているのですが、必要なオプションがかけていたりするんでしょうか？
