nestedScrollview 嵌套使用recyclerview判断滑动到底部 （嵌套滑动导致 不能使用recyclerview的onscrolled监听）

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