创建一个RecyclerView后,单击某个项目时,我注意到了一些奇怪的行为。显示了涟漪效应,但之后会突出显示整个项目。有谁知道为什么RecyclerView项目会以这种方式运行以及这是否是某种错误?

RecyclerView项目布局(单行)

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/linearlayout_listitem_singleline"
    android:foreground="?android:attr/selectableItemBackground"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical">

    <TextView
        android:id="@+id/listitem_singleline_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:padding="12dp"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:textColor="?android:attr/textColorPrimary" />

</LinearLayout>

RecyclerView项目布局(双行)

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

    android:gravity="center_vertical"
    android:baselineAligned="false"
    android:padding="12dp"
    xmlns:android="http://schemas.android.com/apk/res/android">

    <TextView android:id="@+id/listitem_dualline_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

        android:ellipsize="marquee"
        android:textColor="?android:attr/textColorPrimary"
        android:fadingEdge="horizontal" />

    <TextView android:id="@+id/listitem_dualline_subtitle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignStart="@id/listitem_dualline_title"
        android:textAppearance="?android:attr/textAppearanceSmall"
        android:ellipsize="marquee"
        android:textColor="?android:attr/textColorSecondary"
        android:layout_below="@id/listitem_dualline_title"
        android:fadingEdge="horizontal" />
</RelativeLayout>
