Question

我正在尝试使用此处找到的cardslib库https://github.com/gabrielemariotti/cardslib。我很难将这个添加到我的项目中，并且我唯一可以弄清楚如何将文件复制并粘贴到我的项目中，并更改所有包名以匹配我的项目。问题是在运行时期间会生成以下错误：

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.nick.simplequiz.paid/com.nick.simplequiz.paid.statistics}: android.view.InflateException: Binary XML file line #39: Error inflating class com.nick.simplequiz.paid.view.CardView

这是xml，我相信它有问题：

<com.nick.simplequiz.paid.view.CardView  //starting here
        android:id="@+id/carddemo"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="12dp"
        android:layout_marginRight="12dp"
        android:layout_marginTop="12dp"/>

我不明白导致错误的是什么，我已经验证所有类都被正确复制和重命名，但我不确定还有什么可以尝试。任何建议都表示赞赏。

Answer 1

错误来自不正确的依赖，我知道你说你检查了它但它仍然无法找到它，我会尝试按照作者的指示并尝试修改maven构建文件或者这可能就是许多错误中的第一个

Answer 2

开始使用此项目所需的唯一步骤是在build.gradle文件中添加gradle依赖项（目录树中最低）。

dependencies { 
    compile 'com.github.gabrielemariotti.cards:library:1.7.3' 
}

尝试使用cardslib的问题
