VividView

A ViewGroup that continually animates a stack of two or more children using scaling and fading effects.

Simply use the VividView class either programmatically or in your XML like so:

<ca.nihk.vividview.VividView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:duration="3000"
    app:scale_start="1.0"
    app:scale_end="1.25"
    app:fade_fraction_start="0.8"
    app:start_immediately="false">

    <!-- Make sure to have at least two children here before VividView.start() is called -->

</ca.nihk.vividview.VividView>

The custom attributes are optional and default to the values you see above.

• duration defines how long the combined scaling/fading animation lasts.
• scale_start and scale_end is what your View's scale-x and scale-y properties should start and end at, respectively.
• fade_fraction_start is by what percent of the duration the fade should start, e.g. for a duration of 10000 and a fade_fraction_start of 0.9, the fading part of the animation would start after nine seconds of scaling.
• start_immediately defines whether the animation should start right away or not. If this is set to false then programmatically you can call VividView.start() to start the animation.
• You can also define the interpolator programmatically. By default it's a LinearInterpolator.

Call VividView.start() or VividView.stop() as you see fit to control the state of the animation.
