Question

Recycler视图在imageview中滚动并且imageview保持静止。我的要求是在滚动recyclerview时滚动两个视图。我写的xml如下：

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fillViewport="true"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    app:layout_behavior="@string/appbar_scrolling_view_behavior">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <LinearLayout
            android:gravity="center_vertical"
            android:id="@+id/profileLayout"
            android:layout_width="match_parent"
            android:layout_height="180dp"
            android:background="@color/primary_color"
            android:orientation="vertical"
            android:padding="10dp">

            <de.hdodenhof.circleimageview.CircleImageView
                android:id="@+id/profile_image"
                android:layout_width="96dp"
                android:layout_height="96dp"
                android:src="@drawable/profile_user"
                app:border_color="#ffffff"
                app:border_width="2dp" />

            <TextView
                android:id="@+id/fullNameTextView"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_marginTop="10dp"
                android:textColor="@color/primary_color" />
        </LinearLayout>


    <android.support.v7.widget.RecyclerView
            android:id="@+id/drawerList"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@color/myDrawerBackground"
            app:layout_behavior="@string/appbar_scrolling_view_behavior"/>

    </LinearLayout>

</android.support.v4.widget.NestedScrollView>

如何实现这种类型的滚动？

我认为您应该使用CoordinatorLayout来实现此目的，您可以将ImageView内的CollapsingToolbarLayout放入TextView＆amp;您也可以使用它来设置标题，而不是由fullNameTextView ID指定的<android.support.design.widget.CoordinatorLayout 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:layout_width="match_parent" android:layout_height="match_parent"> <android.support.design.widget.AppBarLayout android:id="@+id/app_bar_layout" android:layout_width="match_parent" android:layout_height="@dimen/collapsible_app_bar_height" android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"> <android.support.design.widget.CollapsingToolbarLayout android:id="@+id/collapsing_toolbar" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/gradient_banner" app:contentScrim="@color/background_content_frame" app:layout_scrollFlags="scroll|exitUntilCollapsed"> <de.hdodenhof.circleimageview.CircleImageView android:id="@+id/profile_image" android:layout_width="96dp" android:layout_height="96dp" android:src="@drawable/profile_user" app:border_color="#ffffff" app:border_width="2dp" app:layout_collapseMode="parallax" /> <android.support.v7.widget.Toolbar android:id="@+id/collapsible_toolbar" android:layout_width="match_parent" android:layout_height="?attr/actionBarSize" android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar" app:layout_collapseMode="pin"/> </android.support.design.widget.CollapsingToolbarLayout> </android.support.design.widget.AppBarLayout> <android.support.v7.widget.RecyclerView android:id="@+id/drawerList" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@color/myDrawerBackground" app:layout_behavior="@string/appbar_scrolling_view_behavior"/> </android.support.design.widget.CoordinatorLayout>，如下所示：

 CollapsingToolbarLayout collapsingToolbar = (CollapsingToolbarLayout) findViewById(R.id.collapsing_toolbar);
 collapsingToolbar.setTitle("Title");

<RelativeLayout     
    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:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/cardview_light_background"
    android:orientation="vertical">

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/scrollView"
        tools:ignore="UselessParent" >

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical"
            tools:ignore="ExtraText"
            android:weightSum="1" >

            <ImageView
                android:id="@+id/image_offer"
                android:layout_width="match_parent"
                android:layout_height="250dp"
                android:scaleType="fitXY"
                app:srcCompat="@drawable/kuhnyamain"
                tools:ignore="ContentDescription" />

            <android.support.v7.widget.RecyclerView
                android:id="@+id/recyclerView"
                android:layout_marginTop="250dp"
                android:layout_width="match_parent"
                android:layout_height="wrap_content" >
            </android.support.v7.widget.RecyclerView>

        </LinearLayout>

    </ScrollView>

</RelativeLayout>
