问题 Tried that : NestedScrollView ns =(NestedScrollView) findViewById(R.id.nested_scroll); ns.setOnScrollChangeListener(new NestedScrollView.OnScrollChangeListener() { @Override public void onScrollChange(NestedScrollView v, int scrollX, int scrollY, int oldScrollX, int oldScrollY) { } }); But got stuck, does anyone have an idea? Just to clearify what i want - i want to be able to observe the scroll state (as in addOnScrollListener of RecyclerView) and check only once, when the scrolling has

webview height grows indefinitely inside a nestedScrollView

This is my layout. When i load google.com, the webview's height keeps growing indefinitely. The onSizeChange function of the webview keeps getting called and i can see the webview keeps expanding indefinitely. I've tried 22.2.1 and 23.1.0 of the design and appcompat libraries and no effect. Any solution ? :-| <android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@android:color/black"> <android

NestedScrollView and Horizontal RecyclerView Smooth Scrolling

♀尐吖头ヾ 提交于 2019-11-28 05:02:28
I have a single vertical nestedscrollview that contains a bunch of recyclerview with a horizontal layoutmanager setup. The idea is pretty similar to how the new google play store looks. I'm able to make it functional but it isn't smooth at all. Here are the problems: 1) The horizontal recyclerview item fails to intercept the touch event most of the times even though i tap right on it. The scroll view seems to take precedence for most of the motions. It's hard for me to get a hook onto the horizontal motion. This UX is frustrating as I need to try a few times before it works.

据效果我们可以分析我的要做的功能布局效果,首先,整个布局存在一个头部的滑动操作区域,包括标题栏和搜索栏,然后整个布局还包含了一个滑动控件,滑动控件我们可以使用ScrollView或者NestedScrollView,过程中我们需要监听获取上下滑动的距离,因此需要自定义我们的滑动控件,获取滑动的距离: 自定义滑动控件:AnimationNestedScrollView public class AnimationNestedScrollView extends NestedScrollView { private OnAnimationScrollChangeListener listener; public AnimationNestedScrollView(@NonNull Context context) { super(context); } public AnimationNestedScrollView(@NonNull Context context, @Nullable AttributeSet attrs) { super(context, attrs); } public AnimationNestedScrollView(@NonNull Context context, @Nullable AttributeSet attrs, int

问题 I am using CoordinatorLayout in my activity page. In that there is ListView below the app bar. But its not working when I use ListView instead of NestedScrollView . And if I put ListView inside NestedScrollView , ListView is not expanding 回答1: For the CoordinatorLayout to work properly you need the scrolling child to implement NestedScrollingChild. Such classes are NestedScrollView and RecyclerView . To say it short - just use a RecyclerView for your scrolling content and it'll work correctly

How to put RecyclerView inside NestedScrollView?

With creation of NestedScrollView you can put scrolling view inside another scrolling view as long as those implement NestedScrollingChild and NestedScrollingParent correctly. (This is not bad design pattern "Ian Lake (from Google) actually recommends putting a RecyclerView inside a nestedscrollview here: plus.google.com/u/0/+AndroidDevelopers/posts/9kZ3SsXdT2T") I want to put RecyclerView inside NestedScrollView and fortunately RecyclerView implements NestedScrollingChild so you can put it inside NestedScrollView . public class RecyclerView extends ViewGroup implements ScrollingView,
