StaggeredGridLayoutManager gridLayoutManager = new StaggeredGridLayoutManager(spanCount, StaggeredGridLayoutManager.VERTICAL);gridLayoutManager.setGapStrategy(StaggeredGridLayoutManager.GAP_HANDLING_NONE);//防止item交换位置//以下三行去掉 RecyclerView 动画代码，防止闪烁((DefaultItemAnimator) mRecyclerView.getItemAnimator()).setSupportsChangeAnimations(false);((SimpleItemAnimator) mRecyclerView.getItemAnimator()).setSupportsChangeAnimations(false);mRecyclerView.getItemAnimator().setChangeDuration(0);方法一：mRecyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {@Overridepublic void onScrollStateChanged(RecyclerView recyclerView, int newState) {super.onScrollStateChanged(recyclerView, newState);gridLayoutManager.invalidateSpanAssignments();//重新布局}@Overridepublic void onScrolled(RecyclerView recyclerView, int dx, int dy) {super.onScrolled(recyclerView, dx, dy);}});
方法二：
mRecyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
@Override
public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
// 滑动停止，刷新布局与分割线
if (newState == RecyclerView.SCROLL_STATE_IDLE) {
if (recyclerView.getLayoutManager() instanceof StaggeredGridLayoutManager) {
((StaggeredGridLayoutManager) recyclerView.getLayoutManager()).invalidateSpanAssignments();
recyclerView.invalidateItemDecorations();
}
}
}
});
