在NestedScrollView参数中设置setOnScrollChangeListener以获取

• 嵌套滚动视图v（带滚动的父视图）
• 中间滚动Y
• 整数旧滚动Y

要检测偏移量是否在底部，需要获取内容高度v.getChildAt(0).getMeasuredHeight()的值，并比较当前滚动过父高度，如果有相同的值，则说明已经到了末尾。
可以使用v.getMeasuredHeight()获得父视图的高度

NestedScrollView scroller = (NestedScrollView) findViewById(R.id.myScroll);

if (scroller != null) {

    scroller.setOnScrollChangeListener(new NestedScrollView.OnScrollChangeListener() {
        @Override
        public void onScrollChange(NestedScrollView v, int scrollX, int scrollY, int oldScrollX, int oldScrollY) {

            if (scrollY > oldScrollY) {
                Log.i(TAG, "Scroll DOWN");
            }
            if (scrollY < oldScrollY) {
                Log.i(TAG, "Scroll UP");
            }

            if (scrollY == 0) {
                Log.i(TAG, "TOP SCROLL");
            }

           if (scrollY == ( v.getMeasuredHeight() - v.getChildAt(0).getMeasuredHeight() )) {
               Log.i(TAG, "BOTTOM SCROLL");
           }
       }
    });
}

我知道很晚了，但是......试试这边。

scroll.getViewTreeObserver().addOnScrollChangedListener(new ViewTreeObserver.OnScrollChangedListener() {
    @Override
    public void onScrollChanged() {
            View view = (View) scroll.getChildAt(scroll.getChildCount() - 1);

            int diff = (view.getBottom() - (scroll.getHeight() + scroll
                    .getScrollY()));

            if (diff == 0) {
                getPlaylistFromServer("more");
            }          
    }
});

快乐编码..

Webserveis回答正确，但需要在onScrollChange（override方法）中做一点修改，如下所示：

if (scrollY === v.getChildAt(0).getMeasuredHeight() - v.getMeasuredHeight()) {
   // end of the scroll view
}

Kotlin：

if (scrollY == v.getChildAt(0).measuredHeight - v.measuredHeight) {
    // end of the scroll view
}

@Override
public void onScrollChange(NestedScrollView nestedScrollView, int scrollX, int scrollY, int oldScrollX, int oldScrollY) {
    if (nestedScrollView.getChildAt(nestedScrollView.getChildCount() - 1) != null) {
        if ((scrollY >= (nestedScrollView.getChildAt(nestedScrollView.getChildCount() - 1).getMeasuredHeight() - nestedScrollView.getMeasuredHeight())) &&
                scrollY > oldScrollY) {
            LogsUtils.INSTANCE.makeLogD(">onScrollChange>", ">>BOTTOm");
        }

    }
}

它对我起作用了Source

这对我很有效：

nestedScroll.setOnScrollChangeListener(new NestedScrollView.OnScrollChangeListener() {
        @Override
        public void onScrollChange(NestedScrollView v, int scrollX, int scrollY, int oldScrollX, int oldScrollY) {

            if (v.getChildAt(0).getBottom()<=(nestedScroll.getHeight()+scrollY)) {
                System.out.println("End of NestedScrollView");
            }

        }
    });

基本上，我们在nestedScrollView中添加许多视图，但以Single View的形式将它们 Package 在一起。因此，childCount将始终为1，其索引为0。因此，使用v.getChildAt(0).getBottom()来确定其底部。现在，nestedScroll.getHeight()返回像素高度，scrollY将返回当前垂直原点。因此，每当到达NestedScrollView的底部时，上述条件将为真。

if (v.getChildAt(0).getBottom()==(nestedScroll.getHeight()+nestedScroll.getScrollY()))

这只工作了一段时间...因此，不要以这种方式使用它。

对于API〈23，您可以添加一个treeObserver。scrollChangeLister存储一个本地浮点变量，并检查您滚动方向，如下所示
范例

public class About extends AppCompatActivity implements 
ViewTreeObserver.OnScrollChangedListener{

private float viewScrolled = 0;

   nestedScrollView.getViewTreeObserver().addOnScrollChangedListener(this);

}

@Override
public void onScrollChanged() {

    if (viewScrolled < nestedScrollView.getScrollY()){
        viewScrolled = nestedScrollView.getScrollY();
        Log.d(TAG, "scrolling up");
    }
    if (viewScrolled > nestedScrollView.getScrollY()){
        viewScrolled = nestedScrollView.getScrollY();
        Log.d(TAG, "scrolling down");
    }
}

Webserveis回答正确，但条件应该是这样的

if (scrollY == (v?.getChildAt(0)?.measuredHeight ?: 0) - (v?.measuredHeight ?: 0)) {
    //at bottom
    }

这对我很有效！

my_scroll_view.setOnScrollChangeListener(new NestedScrollView.OnScrollChangeListener() {
            @Override
            public void onScrollChange(NestedScrollView v, int scrollX, int scrollY, int oldScrollX, int oldScrollY) {


                    if (scrollY == v.getChildAt(0).getMeasuredHeight() - v.getMeasuredHeight()) {
                        Log.d(TAG, "onScrollChange: SRCOLLED ==> scrollY: ======================================> THIS IS THE VERY END ");
                    }

                

            }
        });

我只是修改了一点第一个答案的代码，以检测嵌套滚动视图中的循环视图的结尾。

binding.nestedScroll.setOnScrollChangeListener(object:NestedScrollView.OnScrollChangeListener {
        override fun onScrollChange(
            v: NestedScrollView,
            scrollX: Int,
            scrollY: Int,
            oldScrollX: Int,
            oldScrollY: Int
        ) {

        if (scrollY > oldScrollY) {
            Log.i("TAG", "Scroll DOWN");
        }
        if (scrollY < oldScrollY) {
            Log.i("TAG", "Scroll UP");
        }

        if (scrollY == 0) {
            Log.i("TAG", "TOP SCROLL");
        }
       
        if (v.getChildAt(0).getBottom() <= v.height + scrollY)
            {
            Log.i("TAG", "BOTTOM SCROLL IN Recyclerview.");

            Toast.makeText(requireContext(), "Last", Toast.LENGTH_LONG).show()
        }

        }
    })
