Sample

Sample & .aar file

Note

depends from Jake Wharton's NineOldsAndroid, or use my modifed version (included auto cancel)

Using

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

<io.codetail.widget.RevealFrameLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">


&lt;!-- Put more views here if you want, it's stock frame layout  --&gt;

&lt;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"
    /&gt;
</io.codetail.widget.RevealFrameLayout>
    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!

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

Reverse it!

   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

add remote maven url

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

then add a library dependency

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