Question

我有CoordinatorLayout：

<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
                                                 xmlns:app="http://schemas.android.com/apk/res-auto"
                                                 android:layout_width="match_parent"
                                                 android:layout_height="match_parent"
                                                 android:background="@color/background"
                                                 android:clickable="true"
                                                 android:focusableInTouchMode="true">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/bottom_recycle_view"
        android:layout_width="fill_parent"
        android:layout_height="match_parent"
        android:layout_margin="10dp"
        android:background="@drawable/border_gray_solid_background_nop"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"/>


    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/background">

        <com.app.views.textviews.OpSearchView
            android:id="@+id/search_top"

            android:layout_marginTop="@dimen/_20sdp"
            app:hint="@string/filter_categories"
            app:layout_scrollFlags="scroll"/>

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical"
            android:paddingBottom="@dimen/_10sdp"
            app:layout_scrollFlags="scroll">


            <TextView
                android:id="@+id/top_heading"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginBottom="@dimen/default_margin"
                android:layout_marginLeft="@dimen/default_margin"
                android:layout_marginRight="@dimen/default_margin"
                android:layout_marginTop="@dimen/home_screen_sector_spacing"
                android:gravity="left"
                android:textColor="@color/heading_gray"
                android:textSize="@dimen/_14sdp"
                android:textStyle="bold"/>


            <com.app.views.recycleview.HorizontalRecycleView
                android:id="@+id/top_recycle_view"
                android:layout_width="match_parent"
                android:layout_height="@dimen/categories_row_height"
                android:clipToPadding="false"
                android:paddingLeft="@dimen/default_margin"/>


            <TextView
                android:id="@+id/bottom_heading"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_marginLeft="@dimen/default_margin"
                android:layout_marginRight="@dimen/default_margin"
                android:layout_marginTop="@dimen/home_screen_sector_spacing"
                android:gravity="left"
                android:textColor="@color/heading_gray"
                android:textSize="@dimen/_14sdp"
                android:textStyle="bold"/>

        </LinearLayout>


    </android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>

我想让OpSearchView粘在布局的顶部。

我尝试从app:layout_scrollFlags="scroll"中移除OpSearchView，但AppBarLayout的所有孩子都变得很粘。

如果我从OpSearchView下的AppBarLayout移动RecyclerView，则RecyclerView（带有layout_behavior）变得不可见。

如何在没有滚动行为的情况下制作OpSearchView？

这是我在处理布局时所采用的布局，我采取了一些自由来使事情有效，您应该进行自己的更改以使其恢复到原始布局，例如自定义SearchView和HorizontalRecyclerView。 / p>

P.S。对于layout_width和layout_height，match_parent和fill_parent是相同的，您应该只根据Google的文档建议使用match_parent。
