问题 The design support library v. 23.2 introduced BottomSheetBehavior , which allows childs of a coordinator to act as bottom sheets (views draggable from the bottom of the screen). What I’d like to do is to have, as a bottom sheet view , the following view (the typical coordinator + collapsing stuff): <CoordinatorLayout app:layout_behavior=“@string/bottom_sheet_behavior”> <AppBarLayout> <CollapsingToolbarLayout> <ImageView /> </CollapsingToolbarLayout> </AppBarLayout> <NestedScrollView>

问题 I'm using android.support.design.widget and I need to set the position of TabLayout at the activity_main.xml in the bottom of the screen . I've seen that you can use TabHost, but I prefer to use android.support.design ativity_main.xml <android.support.design.widget.AppBarLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"> <android.support.design.widget.TabLayout android:id="@+id/tabs" android:layout

问题 I have a single Activity android app with lots of fragments. When I'm showing a list screen I want to use the Toolbar with the, app:layout_scrollFlags="scroll|enterAlways" property. And in the detail fragments I want to use the CollapsingToolbarLayout with an image in it. Since it's a single Activity app, I have only one Toolbar . Is it possible to modify my layout programmatically to suit both cases? 回答1: Yes. Let's say you are going from the CollapsingToolbarLayout fragment to the Toolbar
