Android RecyclerView最大滚动偏移量

Question

哪个RecyclerView函数返回最大滚动偏移量?

我需要确定，我可以隐藏Activity页脚或不，通过RecyclerView滚动。

Answer 1

请求的函数是recyclerView.computeVerticalScrollRange();

如果到达滚动结束，该函数返回true。

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