问题描述

您好，我正在开发演示应用程序，其中使用了支持库的卡片视图.默认情况下，它会在其周围添加阴影.我要删除此阴影&应该看起来很简单.

Hello I am am working on demo application in which i am using the card view of support library. By default it is adding shadow around it. I want to remove this shadow & should looks like simple.

I tried this that is not working for me.

CardView cardView = (CardView) v.findViewById(R.id.cardView);

layout.xml

layout.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:card_view="http://schemas.android.com/apk/res-auto"
    xmlns:app="http://schemas.android.com/apk/res/com.xyz"
    android:id="@+id/cardView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginBottom="5dp"
    android:layout_marginLeft="5dp"
    android:layout_marginRight="5dp"
    android:orientation="horizontal" >

谢谢.

推荐答案

在XML中使用此属性

card_view:cardElevation="0dp"

，并记住在根目录布局中添加xmlns:card_view="http://schemas.android.com/tools".

and remember add xmlns:card_view="http://schemas.android.com/tools" in your root layout.

OR ，您可以调用cardView.setCardElevation(0)以编程方式禁用阴影.

OR you can call cardView.setCardElevation(0) to disable shadow programmatically.

cardView.setElevation()方法和CardView属性android:elevation将在Android 5.0之前的平台中引发java.lang.NoSuchMethodError

cardView.setElevation() method and CardView attribute android:elevation will throw java.lang.NoSuchMethodError in platform before Android 5.0
