我正在尝试为MvxListView添加涟漪效果，但它还没有到来。这是布局。

我试过android：listSelector =＆＃34; @ drawable / list_selector＆＃34;和android：drawSelectorOnTop =＆＃34; true＆＃34;但效果并未显现 - 。在listview上没有其他任何应用。
这是list_selector：
<?xml version="1.0" encoding="utf-8"?>
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="@color/lg_pressed_state">
<item android:drawable="@color/purple_bw"/>
</ripple>
提前致谢。

我努力实现将项目布局包装在LinearLayout中，并为其添加了纹波。
请尝试让我知道：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/ripple_effect"
android:orientation="vertical">
<RelativeLayout xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/rltContent"
android:background="@color/youBackground"
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- Your content here -->
</RelativeLayout>
</LinearLayout>
Ripple示例：
<ripple xmlns:android="http://schemas.android.com/apk/res/android" android:color="@color/colorPrimaryDark">
<item android:drawable="@color/colorPrimary" />
</ripple>

在将android:background="?selectableItemBackground"设置为列表项并添加onClick侦听器（没有侦听器，单击该项时没有涟漪）时，我总是成功。
也许它也适用于将此背景设置为整个列表或样式;否则，您必须为列表项创建单独的布局文件。
