Using
======

Use regular `RevealFrameLayout` & `RevealLinearLayout` don't worry, only target will be clipped :)

```xml
<io.codetail.widget.RevealFrameLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    
    <!-- Put more views here if you want, it's stock frame layout  -->

    <android.support.v7.widget.CardView
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:id="@+id/awesome_card"
        style="@style/CardView"
        app:cardBackgroundColor="@color/material_deep_teal_500"
        app:cardElevation="2dp"
        app:cardPreventCornerOverlap="false"
        app:cardUseCompatPadding="true"
        android:layout_marginLeft="8dp"
        android:layout_marginRight="8dp"
        android:layout_marginTop="8dp"
        android:layout_width="300dp"
        android:layout_height="300dp"
        android:layout_gravity="center_horizontal"
        />

</io.codetail.widget.RevealFrameLayout>
```

```java

    View myView = findView(R.id.awesome_card);

    // get the center for the clipping circle
    int cx = (myView.getLeft() + myView.getRight()) / 2;
    int cy = (myView.getTop() + myView.getBottom()) / 2;

    // get the final radius for the clipping circle
    int dx = Math.max(cx, myView.getWidth() - cx);
    int dy = Math.max(cy, myView.getHeight() - cy);
    float finalRadius = (float) Math.hypot(dx, dy);

    SupportAnimator animator =
            ViewAnimationUtils.createCircularReveal(myView, cx, cy, 0, finalRadius);
    animator.setInterpolator(new AccelerateDecelerateInterpolator());
    animator.setDuration(1500);
    animator.start();

```

####API that need to mention 

#####Cancel it! 

```java

   SupportAnimator animator = ... ;
   animator.cancel();         

```

#####Reverse it!

```java

   SupportAnimator animator = ... ;
   animator = animator.reverse(); // override with new one

```

How to add dependency
=====================

This library is not released in Maven Central, but instead you can use [JitPack](https://www.jitpack.io/)

add remote maven url

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

then add a library dependency

```groovy
	dependencies {
	    compile ('com.github.ozodrukh:CircularReveal:1.1.1@aar') {
	        transitive = true;
	    }
	}
```
