How to inherit style in layout in Android

Question

I've tried to inherit styles in Android layout xml. Now it looks like:

layout.xml:

<RelativeLayout
    android:id="@id/btn"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:clickable="true"
    style="@style/AppTheme.ButtonLayout">

    <TextView
        android:id="@id/btn_text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        style="@style/AppTheme.ButtonLayout.TextView" />

</RelativeLayout>

styles.xml:

<style name="AppTheme.ButtonLayout">
    <item name="android:textViewStyle">@style/AppTheme.ButtonLayout.TextView</item>
</style>

<style name="AppTheme.ButtonLayout.TextView" parent="android:Widget.Holo.Light.TextView">
    <item name="android:textColor">@android:color/white</item>
</style>

I want to get rid of style attribute from the TextView, but it should inherit appearance from RelativeLayout. Is it possible?

Edit: I want this TextView to have such style only within RelativeLayout with @style/AppTheme.ButtonLayout style. When it is inside layout without this style, it should looks like default Android TextView.

you can inherit styles in Android layout xml from style.xml example at following..

AndroidManifest.xml

 <?xml version="1.0" encoding="utf-8"?>
       <manifest xmlns:android="http://schemas.android.com/apk/res/android"
        package="com.prj.name"
       android:versionCode="1"
        android:versionName="1.0" >

  <uses-sdk
    android:minSdkVersion="11"
    android:targetSdkVersion="19" />

  <application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

  <activity> </activity>
  </application>
</manifest>

themes_apptheme.xml you can call declare name from parent name

 <?xml version="1.0" encoding="utf-8"?>
 <!-- Generated with http://android-holo-colors.com -->
<resources xmlns:android="http://schemas.android.com/apk/res/android">

<style name="AppTheme" parent="@style/_AppTheme" />

<style name="_AppTheme" parent="android:Theme.Holo.Light">

    <item name="android:textColorHighlight">#99ff6d00</item>
       <item name="android:textViewStyle">@style/TextViewAppTheme</item>
</style>

styles_apptheme.xml //what you want to design you can call from drawable folder with png format

 <style name="TextViewAppTheme" parent="android:Widget.Holo.Light.TextView">
    <item name="android:background">@drawable/apptheme_text_holo_light</item>
</style>

style.xml

<style name="Widget.Holo.Light.TextView" parent="Widget.TextView">
    <item name="android:textcolor"> .........</item>
</style>

 <style name="Widget.TextView">
    <item name="android:textAppearance">?android:attr/textAppearanceMediumInverse</item>
    <item name="android:gravity">center_vertical</item>
</style>
