android-collapsingtoolbarlayout

问题 I am making an app that has a ProfilePage with three fragments - About | Posts | Gallery, and I am using a collapsible toolbar with user's image. My second and third fragment will have a footer that should always be visible, but this is what I get: When my image is expanded the footer disappears. What I want is for my two fragments to have these footers always visible and not depending on toolbar being collapsed or not.

问题 I have an activity with XML. Something like: <?xml version="1.0" encoding="utf-8"?> <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=".MainActivity"> <android.support.design.widget.CoordinatorLayout android:id="@+id/coordinator"

In short, this is what I see when

问题 I am looking to add scroll support to more than just a single, scrollable, child view of CoordinatorLayout in conjunction with an AppBarLayout and CollapsingToolbarLayout .

However, when attempting to initiate a scroll event on the LinearLayout above the RecyclerView , nothing happens because the LinearLayout does not know to scroll or collapse the view.

问题 So here is some code from a udacity project for Material Design. It is supposed to show a collapsing toolbar that transforms from a photo with text to simple text. The udacity videos lead me to believe the code worked but when I downloaded the app to my phone, the toolbar did not collapse (the OS is android 6.0.1, v23). Is there something I could change to ensure the toolbar collapses? The code xml <android.support.design.widget.AppBarLayout android:id="@+id/app_bar_layout" android:layout
