How to make Recycler View not scroll when appbar snaps

由 故事扮演 提交于 2019-11-30 08:25:20
问题 I have made the snapping app bar like this: Please note that when the scroll is left in the middle(i.e the title is half visible, then the app bar snaps automatically) In case of google play this is what the snap looks like: Now, I want the snap to work like the one in google play. Which is that when the snap occurs, then only the app bar should snap and the recycler view should not move. It would be better if the solution supported pre lollipop devices too. Thanks! 回答1: I found a solution

CoordinatorLayout with multiple snapping points

Here I've got quite a complex animation that may be resolved (I believe) in a simple way using the CoordinatorLayout . It has 3 states: Initial (left screen) - Header view is shown fully (orange background): Toolbar, grey roundrect (it's actually a photo there) plus some other views below (TextViews, RatingBar etc) Scrolling the content up (middle screen) - roundrect is zooming up with a changing green foreground alpha level over it, so it becomes green while scrolling (well, it is not obvious with these screens. Green background is actually a zoomed roundrect with a green foreground over it,

How to show Toolbar's logo, icon, title, subtitle when wrapped in a CollapsingToolbarLayout?

After Android Support Design Library was released, I wanted to implement an effect like a page of Twitter Profile , in which Toolbar 's title and subtitle could be changed as screen scrolled vertically. So I tried to use CoordinatorLayout , AppBarLayout , CollapsingToolbarLayout and Toolbar from Android Support Design Library to achieve this effect. Everything worked as expected except that Toolbar 's content couldn't be showed or changed as I wanted. I should have been wanting to display collapseIcon , navigationIcon , title , subtitle of Toolbar , but they didn't show up even though I had

Using windowTranslucentStatus with CollapsingToolbarLayout

问题 I'm trying to get a similar effect to what is seen on google play. I've got the below layout to show a transparent toolbar with an image behind it. When the user scrolls there is a parallax effect on the imageview as it scrolls off the screen. The toolbar returns when ever the user scrolls up, with the imageview only returning when the user gets to the lop of the list. This all works great. <android.support.design.widget.CoordinatorLayout android:id="@+id/main" xmlns:android="http://schemas

Prevent RecyclerView from scrolling under AppBarLayout before AppBarLayout is collapsed

由 牧云@^-^@ 提交于 2019-11-30 05:19:54
问题 I'm creating a RecyclerView with header where the header collapses as you scroll up the RecyclerView . I can achieve this very closely with the layout below, with a transparent AppBarLayout , and MyCoolView which is the header. The parallax effect works great. However, if the header is still visible and I fling the RecyclerView , the RV scrolls slowly to the top and some of the items are under the Toolbar until the RV reaches the top of the view. I've been playing around with the scrollFlags

I'm trying to make a layout with a CollapsingToolbarLayout which has scroll|exitUntilCollapsed flag, and a TabLayout which has scroll|enterAlways scrollFlag property. Basically I want my toolbar to be pinned and show and hide the tabs while scrolling. I've modified the cheesesquare app from https://github.com/chrisbanes/cheesesquare . Here is my layout xml; <?xml version="1.0" encoding="utf-8"?> <android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" android:id="@+id/main_content" android

Android status bar scrolling up with coordinator layout, leaving status icons overlapping toolbar title

由 跟風遠走 提交于 2019-11-30 01:55:23
I am experiencing an issue when using Coordinator Layout that contains an AppBarLayout (holding a ToolBar and a TabLayout) and a ViewPager (holding fragments) as children. I want the topbar to be hidden when scrolling down, and revealed when scrolling back up. However when I scroll down, the status bar scrolls up as well, leaving the top bar just below the status icons, being overlapped by them. I tried adding android:fitsSystemWindows="true" to both the AppBarLayout and the ViewPager but nothing changed. Below the code used and snapshots showing the two states: <android.support.design.widget
