AppBarLayout onStopNestedScroll method

AppBarLayoutPart.java

@Override
public void onStopNestedScroll(
    CoordinatorLayout coordinatorLayout, T abl, View target, int type) {
    // onStartNestedScroll for a fling will happen before onStopNestedScroll for the scroll. This
    // isn't necessarily guaranteed yet, but it should be in the future. We use this to our
    // advantage to check if a fling (ViewCompat.TYPE_NON_TOUCH) will start after the touch scroll
    // (ViewCompat.TYPE_TOUCH) ends
    if (lastStartedType == ViewCompat.TYPE_TOUCH || type == ViewCompat.TYPE_NON_TOUCH) {
        // If we haven't been flung, or a fling is ending
        snapToChildIfNeeded(coordinatorLayout, abl);
        // ...
    }
