如何从一个活动，而不是在AppCompatActivity让FAB工作片段(How to make

我把我的FAB的片段从活动中，我不断收到此错误：

摇篮设为

compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support:design:25.3.1'

充气是通过完成：

View mView = inflater.inflate(getlayoutResId(), container, false);

我没有唯一改变的是活性，AppCompatActivity将打了很多现有的代码。我们有没有一种方法，使具有活性本FAB的工作？

FAB：

<android.support.design.widget.FloatingActionButton
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/fab"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_margin="16dp"
    android:src="@drawable/pichere"
    app:backgroundTint="@color/white"
    app:borderWidth="0dp" />

谢谢！

如果我作出了错误的设计，请告知还有什么我可以做，使与FAB的工作这个片段。
