android-nestedscrollview

Is there a way to programmatically scroll to the top of a NestedScrollView by also triggering the scroll events for the parent? smoothScrollTo(x, y) doesn't delegate the scroll events to the NestedScrollingParent . NestedScrollView.scrollTo(0, 0); I managed to do it (animated scrolling): CoordinatorLayout.LayoutParams params = (CoordinatorLayout.LayoutParams) appBarLayout.getLayoutParams(); AppBarLayout.Behavior behavior = (AppBarLayout.Behavior) params.getBehavior(); if (behavior != null) { behavior.onNestedFling(coordinatorLayout, appBarLayout, null, 0, 10000, true); } where 10000 is the

This question already has an answer here: Android prevent nested recyclerview from automatically repositioning [duplicate] 3 answers In a view pager I have several fragments, one of them uses a nested scrollview with a header and a recyclerview : <android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/scrollview" android:layout_width="match_parent" android:layout_height="match_parent" android:fillViewport="true" app:layout_behavior="

Unfortunately, NestedScrollView does

I have a NestedScrollView being used with CoordinatorLayout + AppBarLayout + CollapsingToolbarLayout with parallax effect similar to this tutorial I need to scroll the content programmatically (preferably a smooth scroll, i.e. animated), however calling the scroll methods (scrollBy(), scrollTo(), smoothScrollTo(), smoothScrollBy()) do nothing. Note that I am using app:layout_behavior="@string/appbar_scrolling_view_behavior" <-- Not sure if the issue is related to this. I'm calling nsv_form.smoothScrollBy(0, 300) in Kotlin when a button is clicked by the user, but nothing happens :( (Also tried

Running Android Studio 2.1.2, Windows 7. I replaced a ScrollView with a NestedScrollView and now I'm getting android.view.InflateException: Binary XML file line #2: Error inflating class NestedScrollView java.lang.ClassNotFoundException: Didn't find class "android.view.NestedScrollView" on path: /data/app/com.assemblyguide.remote-48.apk ... when I call SetContentView() on that XML file. I did not get it when I had just a ScrollView. I've tried cleaning, and invalidating the cache and rebuilding. The XML looks like this . . . <?xml version="1.0" encoding="utf-8"?> <NestedScrollView xmlns
