我正在尝试将“TextInputLayout”与“TextInputEditText”一起使用 . 我已经浏览了stackoverflow中的帖子，但没有任何帮助 .

这是我非常简单的代码 -

XML设计：

<?xml version="1.0" encoding="utf-8"?>
<TextInputLayout xmlns:android="http://schemas.android.com/apk/res/android"
                 android:orientation="vertical"
                 android:layout_width="match_parent"
                 android:layout_height="match_parent">
    <android.support.design.widget.TextInputEditText
        android:id="@+id/tv_card_expiration"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:inputType="date"
        android:hint="crap"
        android:paddingStart="10dp"
        android:textSize="20sp"/>
</TextInputLayout>

通货膨胀代码（在我的片段中）：

public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, Bundle savedInstanceState)
{
    return inflater.inflate(R.layout.fragment_purchase, container, false);
}

运行时，返回以下异常：

android.view.InflateException: Binary XML file line #2: Binary XML file line #2: Error inflating class TextInputLayout
                                                                                     Caused by: android.view.InflateException: Binary XML file line #2: Error inflating class TextInputLayout
                                                                                     Caused by: java.lang.ClassNotFoundException: Didn't find class "android.view.TextInputLayout" on path: DexPathList[[zip file "/data/app/com.javaproject.pashnim.pashnimcinema-1/base.apk"],nativeLibraryDirectories=[/data/app/com.javaproject.pashnim.pashnimcinema-1/lib/x86, /system/lib, /vendor/lib]]

                                                                                         at android.view.LayoutInflater.onCreateView(LayoutInflater.java:717)
                                                                                         at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:785)
                                                                                         at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:727)
                                                                                         at android.view.LayoutInflater.inflate(LayoutInflater.java:495)
                                                                                         at android.view.LayoutInflater.inflate(LayoutInflater.java:426)
                                                                                         at com.javaproject.pashnim.cinema.PurchaseFinishFragment.onCreateView(PurchaseFinishFragment.java:23)

或简而言之：

引起：java.lang.ClassNotFoundException：在路径上找不到类“android.view.TextInputLayout”：DexPathList [[zip file“/data/app/com.javaproject.pashnim.pashnimcinema-1/base.apk” ]，nativeLibraryDirectories = [/ data / app / com.javaproject.pashnim.pashnimcinema-1 / lib / x86，/ system / lib，/ vendor / lib]]

Remarkes：

  • 我正在运行Android Studio 3.0 Canary V9

  • Gradle版本："3.0.0-alpha9"

  • 我添加了所需的依赖项：

编译'com.android.support:design:25.3.1'

  • 尝试清洁重建项目 .

有什么想法吗？
