如何在android中为应用程序的背景着色

Question

我添加了一个颜色文件夹,这个xml文件:

    <?xml version="1.0" encoding="utf-8"?>
<item
  xmlns:android="http://schemas.android.com/apk/res/android">
    <color name="orange">#FF9912</color>
</item>

但是当我将值设置在我在values文件夹中创建的screen_display.xml中时.它给了我一个错误:

        <?xml version="1.0" encoding="utf-8"?>
    <resources>
        <style name="MyTheme.Background" parent="@android:style/Theme">
          <item name="android:windowNoTitle"> true</item>
           <item name="android:windowFullscreen">true</item>
           <item name="android:windowBackground">@colors/color/orange</item>
        </style> 
    </resources>

UPDATE
    <activity android:name=".EasyLearningActivity"
                  android:launchMode="singleTask"
                  android:alwaysRetainTaskState="true"
                  android:screenOrientation="portrait"
                  android:configChanges="orientation|keyboardHidden"
                  android:theme="MyTheme.Background"...shows mistake, saying that Strying type inst allowed :(

请在值文件夹中输出这个,先创建两个xml文件

color.xml

<?xml version="1.0" encoding="utf-8"?>

<resources>

<color name="orange">#FF9912</color>

</resources>

styles.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="MyTheme.Background" parent="@android:style/Theme">
      <item name="android:windowNoTitle"> true</item>
       <item name="android:windowFullscreen">true</item>
       <item name="android:windowBackground">@color/orange</item>
    </style> 
</resources>

在清单文件中:

<activity android:name=".EasyLearningActivity"
              android:launchMode="singleTask"
              android:alwaysRetainTaskState="true"
              android:screenOrientation="portrait"
              android:configChanges="orientation|keyboardHidden"
              android:theme="@style/MyTheme.Background"></activity>
