我在android开发方面没有太多经验，尝试在我的应用程序中实现RecyclerView.android studio 版本没有 Android L 也没有安装选项.每次它说 android.support.widget.v7.RecyclerView 未使用并从导入包中禁用它.我也在 Gradle.build 中给出了布局文件中的引用，但我的问题仍然是有人帮忙吗?

• Material Design 中的 CardView 和 RecyclerView

http://icetea09.com/blog/2014/12/19/android-cardview-and-recyclerview-in-material-design/

将这些添加到依赖项:

    compile 'com.android.support:cardview-v7:22.2.0'
    compile 'com.android.support:recyclerview-v7:22.2.0'

并更新模块的build.gradle

• 每个示例:

CardView

<android.support.v7.widget.CardView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    card_view:contentPadding="16dp"
    card_view:cardElevation="2dp"
    card_view:cardCornerRadius="5dp">

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical">

        <TextView
            style="@style/Base.TextAppearance.AppCompat.Headline"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="Title" />

        <TextView
            style="@style/Base.TextAppearance.AppCompat.Body1"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="Content here" />

    </LinearLayout>

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

RecyclerView:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recycler_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

</LinearLayout>
