From source file:com.bar.foldinglayout.sample.FoldingLayoutActivity.java

/**
 * Animates the folding view inwards (to a completely folded state) from its
 * current state and then back out to its original state.
 *///from  w  w w .  j a  va 2 s .  com
public void animateFold() {
    float foldFactor = mFoldLayout.getFoldFactor();

    ObjectAnimator animator = ObjectAnimator.ofFloat(mFoldLayout, "foldFactor", foldFactor, 1);
