Material Design小部件無法讀取樣式屬性

我嘗試使用Material Design創建應用程序。在官方文檔之後，我在文件夾values-v21中添加了一個style.xml文件。Material Design小部件無法讀取樣式屬性

<resources> 
    <style name="AppTheme" parent="android:Theme.Material"> 
     <item name="android:colorPrimary">@color/primary</item> 
     <item name="android:colorPrimaryDark">@color/primary_dark</item> 
     <item name="android:colorAccent">@color/accent</item> 
     <item name="android:textColorPrimary">@color/text_primary</item> 
    </style> 
</resources>

當我用設計支持庫中的一個小部件膨脹佈局時出現問題。

<android.support.design.widget.CoordinatorLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    tools:context=".ui.intro.LoginFragment"> 

<LinearLayout 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical"> 

    <android.support.design.widget.TextInputLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content"> 

     <EditText 
      android:id="@+id/etEmail_loginFragment" 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:hint="@string/Email" 
      android:inputType="textEmailAddress" 
      android:textSize="@dimen/text_normal"/> 

    </android.support.design.widget.TextInputLayout> 

    <android.support.design.widget.TextInputLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content"> 

     <EditText 
      android:id="@+id/etPassword_loginFragment" 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:hint="@string/Password" 
      android:inputType="textPassword" 
      android:textSize="@dimen/text_normal"/> 

    </android.support.design.widget.TextInputLayout> 

    <Button 
     android:id="@+id/btnLogin_loginFragment" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="@string/Login" 
     android:textColor="@color/text_primary" 
     android:textSize="@dimen/text_normal"/> 

    <com.google.android.gms.common.SignInButton 
     android:id="@+id/btnGoogleSignIn_loginFragment" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_gravity="center"/> 

</LinearLayout> 


<ProgressBar 
    android:id="@+id/progress_loginFragment" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_gravity="center" 
    android:indeterminate="true" 
    android:visibility="gone"/> 

</android.support.design.widget.CoordinatorLayout>

Android Studio中佈局的預覽說：

未能轉換ATTR/colorPrimaryDark成繪製（未顯示3個類似的錯誤）

的3個錯誤的？涉及到CoordinatorLayout和兩個TextInputLayout。如果我運行應用程序，當我吹佈局進入分片我得到這個：

這些線是不夠的：

<item name="android:colorPrimary">@color/primary</item> 
<item name="android:colorPrimaryDark">@color/primary_dark</item> 
<item name="android:colorAccent">@color/accent</item> 
<item name="android:textColorPrimary">@color/text_primary</item>

你應該與這些一起使用：

<item name="colorPrimary">@color/primary</item> 
<item name="colorPrimaryDark">@color/primary_dark</item> 
<item name="colorAccent">@color/accent</item> 
<item name="textColorPrimary">@color/text_primary</item>

一起使用它們。 Android 5.0+設備讀取上半部分的行，但AppCompat（舊設備）僅檢查沒有android:的行。

謝謝丹尼爾。我按照你的說法改變了，並且我還要在樣式文件中添加colorControlActivated字段。 –
