How to use:

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">

<!-- 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>

 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);

// Android native animator
  Animator animator =

 ViewAnimationUtils.createCircularReveal(myView, cx, cy, 0, finalRadius);

  animator.setInterpolator(new AccelerateDecelerateInterpolator());

  animator.setDuration(1500);

  animator.start();
