要添加到@Sohaib的答案:

@Alanv是对的,OP不需要面具.但是,如果你的一个选择器状态是透明的,你需要一个掩码,它会在这里:

<?xml version="1.0" encoding="utf-8"?>
<ripple
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:color="@color/ripple_color">

    <!-- mask here... -->
    <item android:id="@android:id/mask">
        <color android:color="@color/black"/> <!-- any color will do -->
    </item>

    <item>
        <selector>
            <!-- ... NOT here. -->
            <item android:state_selected="true">
                <color android:color="@color/blue"/>
            </item>

            <item android:state_activated="true">
                <color android:color="@color/red"/>
            </item>

            <item>
                <color android:color="@color/transparent"/>
            </item>
        </selector>
    </item>
</ripple>

我最初在我的选择器里面有一个面具:boom:

将上述答案与其他答案结合起来:

Ripple,colorPrimary或​​colorAccent的颜色应该是多少？(材料设计)

产生良好的涟漪效果,当项目处于选定状态时也适用.

<ripple xmlns:android="http://schemas.android.com/apk/res/android"
    android:color="?attr/colorControlHighlight">
<!-- Ripple mask - applied to all selector states -->
<item android:id="@android:id/mask">
    <color android:color="#42ffffff" />
</item>
<!-- Selected state of item -->
<item>
    <selector>
        <item android:state_selected="true">
            <color android:color="?attr/colorAccent" />
        </item>
    </selector>
</item>
</ripple>

这在你的drawable-v21文件夹中,对于其他平台,你可以创建一个使用强调颜色的选择器:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/accent" android:state_selected="true"/>
    <item android:drawable="@color/accent" android:state_pressed="true"/>
</selector>
