由于滑动刷新布局，我无法向上滚动
这么多类似的问题，但我的却有些不同。向下滚动时，活动将完美进行。但是，当我向上滚动而不是滚动时，它会刷新。我真正想要的是，只有当我位于嵌套滚动视图的顶部时，它才会刷新。我必须快速双击，才能向上滚动，这有点困难。

我已经通过将“滑动刷新”布局放入“协调器”布局中来解决了该问题。非常感谢所有观众：）

答案 1 :(得分：0)
我在 OnScrollChangeListener 上添加了 ScrollView 以根据滚动的位置启用/禁用 SwipeRefreshLayout。仅当 scrollY 位于顶部并且它不会妨碍我的 scrollView 时，我才启用滑动刷新。
Kotlin 中的代码如下所示：
scrollView.setOnScrollChangeListener { v: View, scrollX: Int, scrollY: Int, _: Int, _: Int ->
swipeRefreshLayout.isEnabled = scrollY == 0
}
答案 2 :(得分：0)
下面是这样解决的
scrollView.setOnScrollChangeListener(new View.OnScrollChangeListener() {
@Override
public void onScrollChange(View v, int scrollX, int scrollY, int oldScrollX, int oldScrollY) {
if(scrollY > 5){
mSwipeRefreshLayout.setEnabled(false);
}else{
mSwipeRefreshLayout.setEnabled(true);
}
}
});
答案 3 :(得分：0)
如果 RecyclerView 或 ListView 不是 SwipeRefreshLayout 的直接子代，则会出现此问题。
最简单的解决方案是提供 OnChildScrollUpCallback 实现并适当地返回结果。在下面的 Kotlin 代码中，refreshLayout 是 SwipeRefreshLayout，recyclerView 是 RecyclerView，这也可以在 xml 布局代码中看到。
refreshLayout.setOnChildScrollUpCallback(object : SwipeRefreshLayout.OnChildScrollUpCallback {
override fun canChildScrollUp(parent: SwipeRefreshLayout, child: View?): Boolean {
if (recyclerView != null) {
return recyclerView.canScrollVertically(-1)
}
return false
}
})
虽然 xml 布局是这样的，
<androidx.swiperefreshlayout.widget.SwipeRefreshLayout
android:id="@+id/refreshLayout"
...
lots of other views i.e TextView, ImageView, MotionLayout
...
...
...
<androidx.recyclerview.widget.RecyclerView
android:id="@+id/recyclerView".../>
...
...
...
</androidx.swiperefreshlayout.widget.SwipeRefreshLayout>
