RippleEffect

================



![RippleEffect](https://github.com/traex/RippleEffect/blob/master/header.png)



ExpandableLayout provides an easy way to create a view called header with an expandable view. Both view are external layout to allow a maximum of customization. [You can find a sample](https://github.com/traex/ExpandableLayout/blob/master/sample/) that how to use an ExpandableLayout to your layout.

### Integration

The lib is available on Maven Central, you can find it with [Gradle, please](http://gradleplease.appspot.com/#rippleeffect)



``` xml



dependencies {

    compile 'com.github.traex.rippleeffect:library:1.3'

}



```



### Usage



#### RippleView



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



``` xml



  



```



If you want to know when the Ripple effect is finished, you can set a listener on your view

``` java

    rippleView.setOnRippleCompleteListener(new RippleView.OnRippleCompleteListener() {



        @Override

        public void onComplete(RippleView rippleView) {

            Log.d("Sample", "Ripple completed");

        }



    });

```



If you want to add an `OnClickListener` don't forget to add it to the RippleView like this:

``` java

    final RippleView rippleView = (RippleView) findViewById(R.id.rippleView);

    rippleView.setOnClickListener(new View.OnClickListener() {

        @Override

        public void onClick(View v) {

            //TODO: onRippleViewClick

        }

    });

```



### 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



For each attribute you can use getters and setters to change values dynamically.



### Troubleshooting



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