Declare a RippleView inside your XML layout file with a content like an ImageView or whatever.

<com.andexert.library.RippleView
  android:id="@+id/more"
  android:layout_width="?android:actionBarSize"
  android:layout_height="?android:actionBarSize"
  android:layout_toLeftOf="@+id/more2"
  android:layout_margin="5dp"
  ripple:rv_centered="true">

  <ImageView
    android:layout_width="?android:actionBarSize"
    android:layout_height="?android:actionBarSize"
    android:src="@android:drawable/ic_menu_edit"
    android:layout_centerInParent="true"
    android:padding="10dp"
    android:background="@android:color/holo_blue_dark"/>

</com.andexert.library.RippleView>

Customization

You can change several attributes in the XML file, you have to remove "rv_" if you are using a version below v1.1.1 :

app:rv_alpha [integer def:90 0-255] --> Alpha of the ripple
app:rv_framerate [integer def:10] --> Frame rate of the ripple animation
app:rv_rippleDuration [integer def:400] --> Duration of the ripple animation
app:rv_ripplePadding [dimension def:0] --> Add a padding to the ripple
app:rv_color [color def:@android:color/white] --> Color of the ripple
app:rv_centered [boolean def:false] --> Center ripple in the child view
app:rv_type [enum (simpleRipple, doubleRipple) def:simpleRipple] --> Simple or double ripple
app:rv_zoom [boolean def:false] --> Enable zoom animation
app:rv_zoomDuration [integer def:150] --> Duration of zoom animation
app:rv_zoomScale [float def:1.03] --> Scale of zoom animation

Troubleshooting

If you want to use the double ripple you have to set a background for the RippleView or for its child.
