动画师和Theme.AppCompat有什么关系？

当我在res /动画文件夹中创建rotation.xml，Android的工作室总是抛出错误：动画师和Theme.AppCompat有什么关系？

的AndroidManifest.xml：

<application 
     android:allowBackup="true" 
     android:icon="@mipmap/ic_launcher" 
     android:label="@string/app_name" 
     android:supportsRtl="true" 
     android:theme="@style/AppTheme"> 
     <activity android:name=".LoadingActivity"> 
      <intent-filter> 
       <action android:name="android.intent.action.MAIN"/> 

       <category android:name="android.intent.category.LAUNCHER"/> 
      </intent-filter> 
     </activity> 
    </application>

styles.xml：

<!-- Base application theme. --> 
    <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar"> 
     <!-- Customize your theme here. --> 
     <item name="colorPrimary">@color/colorPrimary</item> 
     <item name="colorPrimaryDark">@color/colorPrimaryDark</item> 
     <item name="colorAccent">@color/colorAccent</item> 
    </style>

LoadingActivity.java：

public class LoadingActivity extends AppCompatActivity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_loading); 
    } 
}

的build.gradle：

android { 
    compileSdkVersion 23 
    buildToolsVersion "23.0.2" 

    defaultConfig { 
     applicationId "com.kycq.demo" 
     minSdkVersion 14 
     targetSdkVersion 23 
     versionCode 1 
     versionName "1.0" 
    } 
    buildTypes { 
     release { 
      minifyEnabled false 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     } 
    } 
} 

dependencies { 
    compile fileTree(dir: 'libs', include: ['*.jar']) 
    testCompile 'junit:junit:4.12' 
    compile 'com.android.support:appcompat-v7:23.2.0' 
}

我不知道如何解决这个问题，这让我疯了。

试图提供的主题活动也：

<activity 
    android:name=".LoadingActivity" 
    android:theme="@style/AppTheme">

OK，它work.but必须将主题设定为每一个活动为什么要设置AppTheme不能工作的每一个活动？ –

无论如何，它应该通过在'application'中添加主题属性来实现。但不知何故，活动无法从应用程序继承它。顺便说一下，为每个活动添加主题属性并不是一个坏主意。 –
