例外:android.view.InflateException:二进制XML文件行#2:错误膨胀类android.support.v7.widget.CardView

Question

我CardView在我的Android应用程序中使用支持库.我尝试了4-5个小时来解决这个问题,但我无法获得成功.

我已经CardView在我的项目和v7 appcompat中添加了库

<android.support.v7.widget.CardView
    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="match_parent"
    android:layout_margin="5dp"
    android:orientation="horizontal"
    app:cardCornerRadius="4dp" >

但我的应用程序崩溃与下面的日志

Answer 1

让cardview作为库导入:
转到文件 - >导入 - >现有Android代码进入工作区 - >浏览(转到sdk/extras/android/support/v7/cardview) - >单击确定 - >单击完成

您的项目资源管理器现在将cardview显示为项目.

右键单击cardview项目 - >属性 - > Android(左窗格) - >启用isLibrary(勾选复选框) - >应用 - >确定

现在右键单击你的项目 - >属性 - > Android(左窗格) - >添加(在库下) - > cardview - > apply - > ok

现在再次右键单击您的项目 - >构建路径 - >配置构建路径 - >在项目选项卡下,添加cardview

你完成了.

尝试这个..

<android.support.v7.widget.CardView
    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"
    android:id="@+id/card_view"
    android:layout_gravity="center"
    android:layout_width="200dp"
    android:layout_height="200dp"
    card_view:cardCornerRadius="4dp">


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