Question

我有这个屏幕，除了标题之外，所有项目都封装在RecyclerView内。现在的问题是，RecyclerView设置为特定宽度，而标头设置为match_parent。我希望能够使用屏幕上的其余项目滚动标题（因此它看起来像RecyclerView的一部分）而不更改宽度。那是可能的吗？

我的XML代码：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:id="@+id/activity_funky_recycler_view"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="vertical">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Some random header"
        android:background="@color/colorAccent"
        android:gravity="center"
        android:textSize="24sp"
        android:paddingTop="8dp"
        android:paddingBottom="8dp"/>

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recycler_view"
        android:layout_width="512dp"
        android:layout_height="match_parent"/>

</LinearLayout>

它看起来像什么：

<ScrollView
    android:id="@+id/activity_funky_recycler_view"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/scroll"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginTop="5dp">

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

    <TextView
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="Some random header"
        android:background="@color/colorAccent"
        android:gravity="center"
        android:textSize="24sp"
        android:paddingTop="8dp"
        android:paddingBottom="8dp"/>

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recycler_view"
        android:layout_width="512dp"
        android:layout_height="match_parent"/>

</LinearLayout>

您应该在RecyclerView中添加以下行：

app:layout_behavior="@string/appbar_scrolling_view_behavior"

试试这个

<android.support.v4.widget.NestedScrollView
    android:id="@+id/scrollview"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fillViewport="true"
    app:layout_behavior="@string/appbar_scrolling_view_behavior">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <android.support.v7.widget.CardView
            android:id="@+id/cardview1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_margin="@dimen/card_margin">

            <LinearLayout
                style="@style/Widget.CardContent"
                android:layout_width="match_parent"
                android:layout_height="wrap_content">

                <TextView
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:text="Info CardView1"
                    android:textAppearance="@style/TextAppearance.AppCompat.Title" />

                <TextView
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:text="@string/cheese_ipsum" />

            </LinearLayout>

        </android.support.v7.widget.CardView>

        <android.support.v7.widget.CardView
            android:id="@+id/cardview2"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_below="@+id/cardview1"
            android:layout_margin="@dimen/card_margin">

            <LinearLayout
                style="@style/Widget.CardContent"
                android:layout_width="match_parent"
                android:layout_height="wrap_content">

                <TextView
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:text="Info CardView2"
                    android:textAppearance="@style/TextAppearance.AppCompat.Title" />

                <TextView

                    android:layout_height="wrap_content"
                    android:text="@string/cheese_ipsum" />

            </LinearLayout>

        </android.support.v7.widget.CardView>

        <android.support.v7.widget.RecyclerView
            android:id="@+id/recyclerview"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_below="@+id/cardview2"
            android:clipToPadding="false"
            android:paddingTop="0dp"/>

    </RelativeLayout>

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

活动

RecyclerViewAdapter recyclerViewAdapter = new RecyclerViewAdapter(true); // true: with header
RecyclerView recyclerView = (RecyclerView) findViewById(R.id.recyclerview);            
final MyLinearLayoutManager layoutManager = new MyLinearLayoutManager(this, 
LinearLayoutManager.VERTICAL, false, getScreenHeight(this)); // final CustomLinearLayoutManager layoutManager = new CustomLinearLayoutManager(this, LinearLayoutManager.VERTICAL, false);
recyclerView.setLayoutManager(layoutManager);
recyclerView.setAdapter(recyclerViewAdapter);  // recyclerView.setNestedScrollingEnabled(false); // Disables scrolling for RecyclerView, however, CustomLinearLayoutManager used instead of MyLinearLayoutManager

Answer 3

考虑使用CollapsingToolbarLayout。它实现了您想要的功能。

是否可以在回收站视图外部使用列表滚动？
