滚动使Gap处于交错网格视图中

Question

我的Staggered Gridview布局存在一个带有滚动的差距问题。我在这个gridview中使用分页。如果我滚动继续上下，然后我滚动顶部的间隙。

活动代码

staggeredGridLayoutManager = new StaggeredGridLayoutManager(2, StaggeredGridLayoutManager.VERTICAL);
staggeredGridLayoutManager.setGapStrategy(StaggeredGridLayoutManager.GAP_HANDLING_NONE);
search_recyclear_view.setLayoutManager(staggeredGridLayoutManager);

ScrollListener

 search_recyclear_view.addOnScrollListener(new EndlessRecyclerOnScrollListener(staggeredGridLayoutManager) {
            @Override
            public void onLoadMore(int current_page) {
                //for no gap use this
                ((StaggeredGridLayoutManager)search_recyclear_view.getLayoutManager()).invalidateSpanAssignments();
                // do something...
                getData();
        }

ImageAdapter

 RelativeLayout.LayoutParams rlp = (RelativeLayout.LayoutParams) imageView.getLayoutParams();
            rlp.height = (int) (rlp.width * item.getImage_ratio());
            imageView.setLayoutParams(rlp);
            imageView.setHeightRatio(item.getImage_ratio());
            Picasso.with(mContext)
                    .load(baseuri + item.getImageName()).placeholder(PlaceHolderDrawableHelper.getBackgroundDrawable(position))
                    .into(imageView);

提前致谢。

Answer 1

StaggeredGridLayoutManager sGrid = new StaggeredGridLayoutManager(2, StaggeredGridLayoutManager.VERTICAL);
sGrid.setGapStrategy(StaggeredGridLayoutManager.GAP_HANDLING_MOVE_ITEMS_BETWEEN_SPANS);

试试。

交错网格可能在布局边缘有间隙。为了避免这些间隙，StaggeredGridLayoutManager可以独立偏移跨距或在跨距之间移动项目。您可以通过setGapStrategy（int）控制此行为。
