ViewRevealAnimator Widget

ViewAnimator view with a lollipop style reveal effect. Regular animation can be set (just like the default ViewAnimator) for android < 21.

Installation

Just add this to your gradle build script:

compile 'it.sephiroth.android.library.viewrevealanimator:view-reveal-animator:+'

Usage

<it.sephiroth.android.library.viewrevealanimator.ViewRevealAnimator
    android:layout_centerHorizontal="true"
    android:id="@+id/animator"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:animationDuration="@android:integer/config_longAnimTime"
    app:vra_hideBeforeReveal="true"
    android:measureAllChildren="true"
    android:animateFirstView="true"
    android:outAnimation="@anim/out_animation"
    android:inAnimation="@anim/in_animation"
    android:interpolator="@android:interpolator/accelerate_decelerate">


    <Your Views here />


</it.sephiroth.android.library.viewrevealanimator.ViewRevealAnimator>

Then in your code:

ViewRevealAnimator mViewAnimator = (ViewRevealAnimator) findViewById(R.id.animator);

To show the next or previos index :

mViewAnimator.showNext();
mViewAnimator.showPrevious();

or:

mViewAnimator.setDisplayedChild(mViewAnimator.getDisplayedChild()+1, true, new Point(250, 250));

where the first parameter is the targetChild to display, second means animation on/off, and third parameter (optional) is to set a custom origin for the reveal/hide animation
