[游戏开发]Android Recycler Tips 之 smoothScrollToPosition 和 scrollToPosition 触发 ScrollListener

1.在recyclerView中，scrollToPosition 不会触发 scrollListener，而 smoothScrollToPosition 会触发 scrollListener 。源码分析可参考
2.监听 smoothScrollToPosition 滑动动画停止时，的例子：

private void scrollToPosition(int position){
    recyclerView.removeOnScrollListener(onScrollListener);
    recyclerView.addOnScrollListener(onScrollListener);
    recyclerView.smoothScrollToPosition(position);
}

RecyclerView.OnScrollListener onScrollListener = new RecyclerView.OnScrollListener() {
       @Override
       public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
           switch (newState) {
               case SCROLL_STATE_IDLE:
                   //we reached the target position
                   recyclerView.removeOnScrollListener(this);
                   break;
           }
       }
   };

其中 SCROLL_STATE_IDLE 状态会在滑动动画结束时，触发。更多状态可参考
