multiplying shadows

[ameron32]

When programmatically attaching this view to a ViewGroup, shadows are added but never removed. This quickly results in added but never removed shadows, stacking and darkening the shadow with a poor result.

Thank you for this library! The solution is explained below:

public class ZDepthShadowLayout extends FrameLayout {
...
onAttachedToWindow() {
...
addView(mShadowView, 0); // source of issue
...
}
...
// START solution to issue
onDetachedFromWindow() {
super.onDetachedFromWindow();
removeViewAt(0);
}
// END solution to issue
...
}
