At the beginning the only purpose was to blur all layers below. Now you can do more :

• Blur background views easily
• Create custom filters and apply them to views backgrounds

Usage

First add jitpack to your projects build.gradle file

allprojects {
       repositories {
           ...
           maven { url "https://jitpack.io" }
       }
}

Then add the dependency in modules build.gradle file

dependencies {
      compile 'com.github.mirrajabi:view-effects:e355a1bac4'
 }

Just do the normal ui stuff

<RelativeLayout
     android:layout_width="match_parent" 
     android:layout_height="match_parent"
     android:id="@+id/root_view">
     <View
         android:layout_width="match_parent"
         android:layout_height="100dp"
         android:layout_marginTop="100dp"
         android:layout_marginLeft="20dp"
         android:layout_marginRight="10dp"
         android:id="@+id/my_view"/>
</RelativeLayout>

Then in your code :

ViewFilter.getInstance(this)
          //Use blur effect or implement your custom IRenderer
          .setRenderer(new BlurRenderer(16)) 
          .applyFilterOnView(findViewById(R.id.my_view),
                            findViewById(R.id.root_view));

You can also implement your own IRenderer and use it as the renderer. in some situations you might want the view background to handle it yourself

ViewFilter.getInstance(this)
          .getFilteredBackgroundOfView(findViewById(R.id.my_view),
                                       findViewById(R.id.root_view));
