奥利奥未提及的属性、风格和主题

在Oreo下,我的主题停止工作(在较低级别的API上工作),并且没有被拾取。我有以下几点:

报告布局。xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/company_list_header"
    android:orientation="horizontal"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    style="?companyTextTitle">

属性。xml

<attr name="companyTextTitle" format="reference"/>

主题。xml

<style name="Theme.Black" parent="Theme">
    <item name="companyTextTitle">@style/company_text_title</item>
</style> 

<style name="Theme" parent="android:Theme">
    <item name="android:listViewStyle">@style/list</item>
    <item name="android:absListViewStyle">@style/list</item>
    <item name="android:editTextStyle">@style/edittext</item>   
    <item name="android:buttonStyle">@style/stdbutton</item>        
    <item name="android:spinnerStyle">@style/spinner</item>   
    <item name="android:spinnerItemStyle">@style/spinneritem</item>   
    <item name="android:checkboxStyle">@style/checkbox</item>   
    <item name="android:radioButtonStyle">@style/radio</item>    
    <item name="android:preferenceStyle">@style/preference</item>    
    <item name="android:listChoiceIndicatorSingle">@drawable/btn_radio</item>         
    <item name="android:spinnerDropDownItemStyle">@style/spinnerradio</item>    
    <item name="android:buttonBarButtonStyle">@style/stdbutton</item>                               
</style> 

样式。xml:

<style name="company_text_title">
    <item name="android:textColor">#000000</item>
    <item name="android:textStyle">bold</item>
    <item name="android:gravity">center_vertical|left</item>
    <item name="android:paddingLeft">2sp</item>
    <item name="android:paddingRight">2sp</item>
    <item name="android:background">#004488</item>
</style>

在我的活动中:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.report_layout);
    setTheme(R.style.Theme_Black);

显示:

<supports-screens 
    android:smallScreens="true"
    android:normalScreens="true"
    android:largeScreens="true"
    android:xlargeScreens="false" 
    android:anyDensity="true"/> 

    <activity android:name=".ReportList" android:label="@string/app">
        <intent-filter>
            <action android:name="com.xyz.app.REPORTLIST"/>
            <category android:name="android.intent.category.DEFAULT"/>
        </intent-filter>
    </activity>

compileSdkVersion 25
buildToolsVersion '25.0.3'

defaultConfig {
    minSdkVersion 14
    targetSdkVersion 14
}

不喜欢:

style="?companyTextTitle">

style="@style/company_text_title">
