android - 如何从 Android L Preview Design 制作 Android List View Design

Question

我制作了 Android L 预览图像样式列表项。这是我对这些类似设计的代码。

//可绘制/list_item_bg.xml

<?xml version="1.0" encoding="utf-8"?>

     <layer-list xmlns:android="http://schemas.android.com/apk/res/android" >
          <item>
                <shape
                 android:shape="rectangle">
                  <solid android:color="#E6E6E6" />
                </shape>
          </item>
          <item android:bottom="1dp">
              <shape
                    android:shape="rectangle">
                   <solid android:color="#FAFAFA" />
              </shape>
          </item>
      </layer-list>

//可绘制/list_icon_bg

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval">
    <solid android:color="@color/list_grey_bg" />
</shape>

//布局/list_item

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="72dp">

    <ImageView
        android:id="@+id/list_icon"
        android:layout_width="40dp"
        android:layout_height="40dp"
        android:layout_margin="16dp"
        android:src="@drawable/thumb"
        android:background="@drawable/list_icon_bg"/>

    <LinearLayout
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center_vertical"
        android:background="@drawable/list_item_bg"
        android:layout_toRightOf="@+id/list_icon"
        android:layout_alignParentRight="true"
        android:layout_alignParentEnd="true"
        android:layout_alignParentTop="true"
        android:layout_alignParentBottom="true">

        <TextView
            android:id="@+id/label"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:textColor="@color/primary_text"
            android:paddingRight="16dp"
            android:text="Sample Text" />

    </LinearLayout>

</RelativeLayout>

但我对列表项的选定状态有疑问。列表项选择状态的背景颜色仅适用于图标区域。选定状态的列表项背景颜色不适用于 LinearLayout 区域。我该如何解决。
