滚动时检测 RecyclerView 何时到达最底部位置 [英] Detect when RecyclerView reaches the bottom most position while scrolling

问题描述

我有一个 RecyclerView 的代码.

I have this code for a RecyclerView.

    recyclerView = (RecyclerView)rootview.findViewById(R.id.fabric_recyclerView);
    recyclerView.setLayoutManager(layoutManager);
    recyclerView.addItemDecoration(new RV_Item_Spacing(5));
    FabricAdapter fabricAdapter=new FabricAdapter(ViewAdsCollection.getFabricAdsDetailsAsArray());
    recyclerView.setAdapter(fabricAdapter);

我需要知道滚动时 RecyclerView 何时到达最底部位置.是否可以 ?如果是，如何?

I need to know when the RecyclerView reaches bottom most position while scrolling. Is it possible ? If yes, how ?

推荐答案

还有一个简单的方法

recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
    @Override
    public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
        super.onScrollStateChanged(recyclerView, newState);

        if (!recyclerView.canScrollVertically(1)) {
            Toast.makeText(YourActivity.this, "Last", Toast.LENGTH_LONG).show();

        }
    }
});

方向整数:-1 表示向上，1 表示向下，0 将始终返回 false.

direction integers: -1 for up, 1 for down, 0 will always return false.
