floatingActionBar floating button quick example

AndroidStudio just needs to add a reference:

compile'com.android.support:design:22.2.1'

layout file:

<android.support.design.widget.FloatingActionButton
   android:layout_width="wrap_content"
    android:id="@+id/flb"
   android:layout_alignParentRight="true"
   android:layout_alignParentBottom="true"
   android:backgroundTint="#f0f0"
    app:elevation="30dp"
    app:fabSize="normal"
    android:src="@drawable/uii"
    app:rippleColor="#0ff"
    android:layout_height="wrap_content"/>

Then add a listener event to this button and write the corresponding function.
