isHiddenPartVisible

public boolean isHiddenPartVisible(CoordinatorLayout parent,
                                   android.view.View child,
                                   VerticalIndicatorBehavior behavior)

Tell if the hidden part of header view is visible. If invisible height is zero, which means visible height equals to view's height, in that case it's considered to be invisible.

Specified by:

isHiddenPartVisible in class VerticalIndicatorBehaviorController

Returns:

true if hidden part of header view is visible, otherwise return false.
