Android RecyclerView最大滚动偏移量

Question

哪个RecyclerView函数返回最大滚动偏移量？

我需要Activity通过RecyclerView滚动来确定,我可以隐藏或不隐藏页脚.

Answer 1

ask函数是recyclerView.computeVerticalScrollRange();

如果到达滚动结束,则此函数返回true.

static private boolean isMaxScrollReached(RecyclerView recyclerView) {
    int maxScroll = recyclerView.computeVerticalScrollRange();
    int currentScroll = recyclerView.computeVerticalScrollOffset() + recyclerView.computeVerticalScrollExtent();
    return currentScroll >= maxScroll;
}
