解决swipeRefreshLayout与RecyclerView的滑动冲突

阅读更多关于解决swipeRefreshLayout与RecyclerView的滑动冲突

网上给出的最多的滑动冲突解决办法思路:首先给RecyclerView添加滑动监听事件，其次获取recyclerView的第一个子布局的位置，如果你是上滑的话，recyclerView.getChildAt(0).getTop()获取的值肯定是个负数，当第一个item项出现，并且在顶部时swipeRefreshLayout才能启用，这样解决滑动冲突，但是这个方法在部分手机上不兼容。网上的源码大概是这样的： recyclerView.addOnScrollListener( new RecyclerView.OnScrollListener() { @Override public void onScrolled (RecyclerView recyclerView, int dx, int dy) { super .onScrolled(recyclerView, dx, dy); int topRowVerticalPosition = (recyclerView == null || recyclerView.getChildCount() == 0 ) ? 0 : recyclerView.getChildAt( 0 ).getTop(); swipeRefreshLayout.setEnabled(topRowVerticalPosition >= 0 ); }
