问题描述
我在 NestedScrollView
中使用了 RecyclerView
.为了平滑滚动
I am using RecyclerView
inside NestedScrollView
. For smooth scrolling
nestedScrollView.setNestedScrollingEnabled(true);
recyclerView.setNestedScrollingEnabled(false);
而且这个 RecyclerView
是动态的,在 scroll
上动态添加行.但是滚动侦听器不起作用 NestedScrollingEnabled
是假的.
And this RecyclerView
is dynamic, dynamically adding rows on the scroll
. But scroll listener is not working NestedScrollingEnabled
is false.
推荐答案
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");
f (viewGroup1.getChildAt(viewGroup1.getChildCount() - 1) instanceof RecyclerView){
//add code here }
}
}
});
