代码示例来源：origin: nickbutcher/plaid

@Override
  public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
    // we want the grid to scroll over the top of the toolbar but for the toolbar items
    // to be clickable when visible. To achieve this we play games with elevation. The
    // toolbar is laid out in front of the grid but when we scroll, we lower it's elevation
    // to allow the content to pass in front (and reset when scrolled to top of the grid)
    if (newState == RecyclerView.SCROLL_STATE_IDLE
        && layoutManager.findFirstVisibleItemPosition() == 0
        && layoutManager.findViewByPosition(0).getTop() == grid.getPaddingTop()
        && toolbar.getTranslationZ() != 0) {
      // at top, reset elevation
      toolbar.setTranslationZ(0f);
    } else if (newState == RecyclerView.SCROLL_STATE_DRAGGING
        && toolbar.getTranslationZ() != -1f) {
      // grid scrolled, lower toolbar to allow content to pass in front
      toolbar.setTranslationZ(-1f);
    }
  }
};
