如何让ScrollView在滚动到末尾时也能使用触摸事件？

ScrollView scrollView = findViewById(R.id.scrollView);
View contentView = scrollView.getChildAt(0);

scrollView.getViewTreeObserver().addOnScrollChangedListener(new ViewTreeObserver.OnScrollChangedListener() {
    @Override
    public void onScrollChanged() {
        int scrollY = scrollView.getScrollY();
        int contentHeight = contentView.getHeight();
        int scrollViewHeight = scrollView.getHeight();

        if (scrollY + scrollViewHeight == contentHeight) {
            // 滚动到末尾，将触摸事件传递给子View处理
            contentView.dispatchTouchEvent(MotionEvent.obtain(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(), MotionEvent.ACTION_DOWN, 0, 0, 0));
        }
    }
});

scrollView.setOnTouchListener(new View.OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        int scrollY = scrollView.getScrollY();
        int contentHeight = contentView.getHeight();
        int scrollViewHeight = scrollView.getHeight();

        if (scrollY + scrollViewHeight == contentHeight) {
            // 滚动到末尾，将触摸事件传递给子View处理
            contentView.dispatchTouchEvent(event);
            return true;
        }

        return false;
    }
});
