android-appbarlayout

问题 Is it really intended that the Toolbar in a AppBarLayout is scrollable although the main container with the "appbar_scrolling_view_behavior" has not enough content to really scroll? What I have tested so far: When I use a NestedScrollView (with "wrap_content" attribute) as main container and a TextView as child, the AppBarLayout works properly and does not scroll. However, when I use a RecyclerView with only a few entries and the "wrap_content" attribute (so that there is no need to scroll),

问题 I am following this popular link for cordinator behaviour, following this post . I wanted a desired behavior that image should be floated to right side instead of left and for this, I modified AvatarImageBehavior.java -> maybeInitProperties() method -> as following : if (mFinalXPosition == 0) mFinalXPosition= getScreenWidth()-70; Now I wish the toolbar to be fixed at top, and only image to move and stick to it. As per my understanding, only Behavior file is responsible for this transition. I

问题 I have a CollapsingToolbar that I have conditionally disabled. When the user loads the view under that condition, it just looks like a normal ToolBar object. The only weird thing is that if they drag down, such as in a pull to refresh style action, the CollapsingToolbar expands, despite my wishes and code to the contrary! Here is what I have, and the commented out code reflects what I have also tried appBar.setExpanded(false); appBar.setActivated(false); /*CollapsingToolbarLayout.LayoutParams

问题 I have the problem that my RecyclerView is cut off behind the AppBarLayout Here is my XML <android.support.v4.widget.DrawerLayout 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/drawer_layout" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".activity.MainActivity"> <android.support.design.widget.CoordinatorLayout android:id="@

问题 I have a really awkward problem that I cannot get rid of and that I absolutely do not understand. I simply want my app bar to collapse and an image to move with some placeholder element in the app bar area. I got this from this example: https://github.com/saulmm/CoordinatorBehaviorExample I use a very simple layout: <CoordinatorLayout> <AppBarLayout> <CollapsingToolbarLayout android:minHeight="96dp" app:layout_scrollFlags="exitUntilCollapsed|scroll"> <FrameLayout android:id="@+id

问题 I've tried setting the action bar I custom-made for my application to be transparent. However instead of being completely transparent, it leaves a weird elevation shadow: http://puu.sh/rdYyb/04ce0147f6.jpg The XML for the bar: <android.support.design.widget.AppBarLayout android:id="@+id/appbarlayout" android:layout_width="match_parent" android:layout_height="wrap_content" android:theme="@style/AppTheme.AppBarOverlay"> <android.support.v7.widget.Toolbar android:id="@+id/toolbar" android:layout

问题 I am facing this issue with coordinator layout about scrolling. For a specific position it wont scroll buy, After clicking on Add new button a list element gets added below. And if we scroll that item the coordinator layout behaves normally like expand and shrink. But when we try to scroll up by touching on the layout main.xml <?xml version="1.0" encoding="utf-8"?> <android.support.design.widget.CoordinatorLayout android:layout_width="match_parent" xmlns:app="http://schemas.android.com/apk

问题 I have an app with two activities extends same abstract - one with WebView , another with ViewPager with TabLayout and RecyclerView s - and on this level I've implemented "shared" showing/hiding toolbar with scroll/fling feature: app:layout_scrollFlags="scroll|snap|enterAlways" WebView is "pushing out" Toolbar just like RecyclerView under any tab in ViewPager (keeping TabLayout visible), in both cases any scroll to top brings back Toolbar . Just like on this example: Now I've to change this

问题 I have a layout with CollapsingToolbarLayout and CoordinatorLayout as root element. Whenever a Snackbar is shown in the activity the title of the toolbar resets its position to the default expanded title position of the CollapsingToolbar even if the toolbar is not (fully) expanded. The second picture shows that the title is fixed no matter if the toolbar expands or not. The result is the same when I call snackbar.show() in activity or fragment . My layout structure looks like this:

问题 I have an AppBarLayout defined as such <android.support.design.widget.AppBarLayout android:id="@+id/appbar_layout" android:layout_width="match_parent" android:layout_height="wrap_content" android:theme="@style/AppTheme.AppBarOverlay"> However, sometimes I change the theme for the application and I also want to change it, and its children's. I have been partially successful by doing this: AppBarLayout appBarLayout = (AppBarLayout) findViewById(R.id.appbar_layout); appBarLayout.getContext()
