无法充实CardView以在RecyclerView中使用

Question

我希望RecyclerView显示多个CardView s。

这是我试图夸大的布局的简化版本（只是更多TextView s：

<?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"
    android:id="@+id/card_view"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    card_view:cardBackgroundColor="@color/background_floating_material_dark"
    card_view:cardCornerRadius="4dp"
    card_view:cardElevation="4dp"
    card_view:cardUseCompatPadding="true">

    <RelativeLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">

    <TextView
        android:id="@+id/waypoint_item"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:text="@string/placeholder_waypoint_name"
        android:textColor="@android:color/primary_text_dark"
        android:textSize="?android:attr/textAppearanceLarge" />

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

从堆栈跟踪中，我知道这些是引起问题的行（在RecyclerView的适配器中）：

try {
    View v = LayoutInflater.from(parent.getContext())
            .inflate(R.layout.waypoint_list_item, parent, false);
    return new ViewHolder(v);
} catch (InflateException e) {
    Log.wtf("ViewHolder", e.getCause());
    throw e;
}

我正在打印抛出的异常和异常的实际原因。 （This表示正在掩盖真正的异常。）

我从中得到的两个输出是第一个例外，包裹InflateException：

第一个例外：

此外，以下是build.gradle（我使用的是Android Studio）与此应用程序对应的相关行：

android {
    compileSdkVersion 21
    buildToolsVersion '21.1.2'

    defaultConfig {
        minSdkVersion 19
        targetSdkVersion 21
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:21.0.3'
    compile 'com.android.support:support-v4:21.0.3'
    compile 'com.android.support:cardview-v7:21.0.+'
    compile 'com.android.support:recyclerview-v7:21.0.+'
}

这是我能想到的所有有用的信息，但我很乐意添加任何额外的信息。类似的问题指向CardView库未被包含，但我相信我通过将其包含在依赖项部分中来解决。我以前有过这个版本的工作，但是我无法让它再次工作 - 即使在撤消我记忆中的所有变化之后也是如此。
