卡片视图 material 涟漪?
Card view material ripple?
我正在开发 material 设计界面。我有一些卡片,我希望在单击时产生连锁反应。我已经按照 google 所说的做了,但没有任何反应。这是我的代码:
<android.support.v7.widget.CardView
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:id="@+id/card_view"
android:layout_gravity="center"
android:clickable="true"
android:layout_width="fill_parent"
android:layout_height="250dp"
android:elevation="5dp"
android:background="?android:selectableItemBackground">
>
<ImageView
android:id="@+id/blue_image"
android:src="@drawable/blue"
android:layout_alignParentTop="true"
android:layout_width="fill_parent"
android:layout_height="200dp"
android:elevation="8dp"
/>
<TextView
android:id="@+id/text_view"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_alignParentBottom="true"
android:text="And this is a blue card!"
android:elevation="10dp"
/>
看看我的例子 (API<21)。类似于棒棒糖波纹效果。

对于这个演示,我使用了这个库:
https://github.com/balysv/material-ripple
只需添加到 build.gradle:
compile 'com.balysv:material-ripple:1.0.1'
卡片视图选择器(包装的 RelativeLayout):list_item_selector.xml:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Pressed -->
<item android:drawable="@color/ripplecolorbackground" android:state_pressed="true"/>
<!-- selected -->
<item android:drawable="@color/ripplecolorbackground" android:state_selected="true"/>
<!-- focused -->
<item android:drawable="@color/ripplecolorbackground" android:state_focused="true"/>
<!-- default -->
<item android:drawable="@color/transparent"/>
布局:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="5dp"
tools:context=".MainActivity">
<android.support.v7.widget.CardView
android:id="@+id/card_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="5dp"
android:layout_marginRight="5dp"
android:layout_marginLeft="5dp"
android:layout_marginBottom="5dp"
card_view:cardUseCompatPadding="true"
card_view:cardCornerRadius="3dp"
card_view:cardElevation="3dp"
card_view:cardPreventCornerOverlap="true">
<com.balysv.materialripple.MaterialRippleLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:mrl_rippleColor="@color/rippplecolorlist"
app:mrl_rippleAlpha="0.10"
app:mrl_rippleOverlay="false"
app:mrl_rippleHover="true"
app:mrl_rippleDimension="1dp"
app:mrl_rippleDuration="350">
<RelativeLayout
android:background="@drawable/list_item_selector"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</com.balysv.materialripple.MaterialRippleLayout>
</android.support.v7.widget.CardView>
颜色:
<color name="ripplecolorbackground">#1A000000</color>
<color name="rippplecolorlist">#26000000</color>
我创建了一个库,允许在不影响布局的情况下自定义每个视图以创建连锁反应
希望对你有帮助

该示例还使用具有这种效果的 cardViews ;)
