no resource id found for app:layout_scrollflags from CollapsingToolbarLayout

阅读更多关于 no resource id found for app:layout_scrollflags from CollapsingToolbarLayout

问题 The title of this question basically says it all. I get the error: no resource identifier found for app:layout_scrollflags from CollapsingToolbarLayout. I use eclipse and imported the design library jar file. I'm able to use the design support layouts in my classes so that's correct this is a piece of the code i use: <LinearLayout 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"

CollapsingToolbarLayout crash on 4.4 devices (java.lang.IllegalArgumentException: radius must be > 0)

阅读更多关于 CollapsingToolbarLayout crash on 4.4 devices (java.lang.IllegalArgumentException: radius must be > 0)

问题 I have implemented the new style Collapsible Toolbar. I am using the same code as the example (Cheesesquare) demo app - which of course works fine on all devices. I need help figuring out what I am doing different then the sample (so my app won't crash). My app runs great on 5.0+ devices, but crashes on older devices (OS 4.4.4) with an error that I can't isolate to my code (no references to my project's classes in the stack). Seems so strange to me that this is device specific (if this was a

Panning google map in CoordinatorLayout causes recyclerview to scroll in android design support library 23.0.1

阅读更多关于 Panning google map in CoordinatorLayout causes recyclerview to scroll in android design support library 23.0.1

问题 The map is in a collapsingToolbarLayout which is nested in an appBarLayout. In versions 22.2.0 and 22.2.1 of the android design support library, I could pan around the map independently of the coordinatorLayout but in 23.0.1, if i try to pan across the map in the north/south axis, it causes the recyclerview to scroll up/down. Is this a bug or is there a way to pass the touch events from the appBarLayout to the mapFragment? <android.support.design.widget.AppBarLayout android:id="@+id/app_bar

RecyclerView (horizontal) nested in BottomSheet preventing vertical scrolling

阅读更多关于 RecyclerView (horizontal) nested in BottomSheet preventing vertical scrolling

问题 I have a RecyclerView using a LinearLayoutManager with HORIZONTAL orientation, nested inside a FrameLayout using the BottomSheet Behavior . When attempting to drag vertically across the RecyclerView , the BottomSheet doesn't respond to the drag event. Presumably this is because vertical scrolling is disabled for a LayoutManager with horizontal orientation. I've tried overriding LinearLayoutManager.canScrollVertically() and returning true. This sort of works.. If you drag vertically in a very

阅读更多关于 Switch in Navigation drawer item with Design Support Library on Android

I need to put Switch inside item in navigation drawer. I'm using new design support library, but I cannot find if it is posibble at all. When using android:checkable item is just full selected and that is not what I wish. This is screenshot of what I really want. Is that possible to achieve that? Your menu item for the navigation drawer: <item android:id="@+id/nav_item1" android:icon="@drawable/ic_item1" android:title="item1" app:actionLayout="@layout/layout_switch" /> and the layout for that item: <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com

(Design Support Library) CollapsingToolbarLayout — Toolbar not getting pinned on collapse

阅读更多关于 (Design Support Library) CollapsingToolbarLayout — Toolbar not getting pinned on collapse

I'm having trouble integrating the Design Support Library into my application. For some reason, the toolbar collapses with the CollapsingToolbarLayout, and does not leave it pinned like in the Cheesesquare example by Chris Banes. https://github.com/chrisbanes/cheesesquare I didn't do anything different to my layout. In fact, I replaced my styles with his, and dropped in his layout. I wonder if using Toolbar, instead of android.support.v7.widget.Toolbar is causing this. Here is the problem. Here is my XML of the AppBar section. <android.support.design.widget.CoordinatorLayout xmlns:android=
