I have tried every flag in collapsing toolbar. <android.support.design.widget.CoordinatorLayout 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/coordinatorLayout"

问题 I'm going to achieve this UI in my App: Well, Some ways that I tried before: 1. Using CollapsingToolbarLayout I put my CardView insid of CollapsingToolbarLayout and put them all in AppBarLAyout. <android.support.design.widget.CoordinatorLayout android:layout_width="match_parent" android:layout_height="match_parent" > <android.support.design.widget.AppBarLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

问题 I have a layout with a CoordinatorLayout, and AppBarLayout and a NestedScrollView, inside the NestedScrollView I have multiple CardViews, everything works ok until I set the CardViews to be clickable, then if I start a scroll within a CardView, scroll doesn't work.

问题 Overview I am trying to implement one of the Scrolling Techniques, Flexible space with overlapping content , described in Material Design. Flexible space with overlapping content Content can overlap the app bar. Behavior: The app bar’s starting position should be located behind the content. Upon upward scroll, the app bar should scroll faster than the content, until the content no longer overlaps it. Once anchored in place, the app bar lifts up to allow content to scroll underneath. https:/

问题 I want to use NestedScrollView with CollapsingToolbarLayout. In NestedScrollView there is really long content. Unfortunately I can't scroll to the end. Some of this long content is cut.

问题 I have a fairly typical List functionality using a CoordinatorLayout, AppBarLayout, SwipeRefreshLayout and RecyclerView - When the RecyclerView has enough content to scroll, the page seems fine. When the RecyclerView is empty or doesn't have enough content to scroll however, the behavior is that the AppBarLayout children with app:layout_scrollFlags="scroll|enterAlwaysCollapsed" will continue to scroll - which looks odd. Is there a way to stop the AppBarLayout children scrolling when the

问题 I am working on an application where I'm using AppBarLayout with CollapsingToolbarLayout and NestedScrollView. I have successfully implemented this and it is working fine. Now what i am trying to do is, that on fling(fast swipe up) on the Nestedscrollview it should scroll completely to top. Similarly, on fling(fast swipe down) towards the bottom of the screen, it must scroll all the way to the bottom smoothly. However now, it only gets stuck in between which makes it look ugly. I have tried
