我正在使用RecyclerView来显示报价列​​表片段。我试图在列表项中使用Ripple效果,但它不起作用。我的RecyclerView如下所示

<android.support.v7.widget.RecyclerView
        android:id="@+id/listQuoteView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="?attr/BackColor"
        android:layout_above="@+id/startAppBanner"
        android:layout_alignParentTop="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true" />

List List XML如下所示

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

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


    <android.support.v7.widget.CardView

            </LinearLayout>

        </LinearLayout>

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


</RelativeLayout>

我已尝试过stackoverflow中列出的许多解决方案,但没有任何解决方案。我 f我从列表项目中移除了cardview ....显示在LinearLayout后面的Ripple效果但我也想使用cardview。如果有人可以帮我解决这个问题,请告诉我。感谢

注意:我已使用this solution解决了这个问题。感谢

this.settings = { columns: { 'Channel': {title: 'Channel'}, 'Channel Label': {title: 'Channel Name'}, 'Video': {title: 'Video', type: 'custom', renderComponent: PasswordRenderComponent} }} 上将纹波设置为前景 drawable:

CardView

这样可以让涟漪在android:foreground="?attr/selectableItemBackground" 内的上面显示,这通常是CardView

的内容

答案 1 :(得分:1)

使用android:background="?android:attr/selectableItemBackground"

答案 2 :(得分:1)

创建涟漪 drawable 并将其设置为布局的前景

<强> ripple.xml

<ripple xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:color="@color/your_color"
    tools:targetApi="lollipop">
    <item android:id="@android:id/mask">
        <shape android:shape="rectangle">
            <solid android:color="@color/your_color" />
        </shape>
    </item>
</ripple>

更改您的代码:

<RelativeLayout
    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="wrap_content">


    <android.support.v7.widget.CardView
        android:clickable="true"
        android:foreground="@drawable/ripple"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="4dp"
        android:layout_marginLeft="8dp"
        android:layout_marginRight="8dp"
        android:layout_marginTop="4dp"
        app:cardCornerRadius="6dp"
        app:cardElevation="4dp">
