How to avoid a duplicate style item?

Question

How do I avoid duplicate style items in the below example?

I have textSize 30sp with the style - TextStyle.

<style name="TextStyle">
     <item name="android:textSize">30sp</item>
</style>

The same textSize 30sp I am using in the below style. Is there any method apply the textsize- without duplicate writing of the style?

<style name="bottomText">
    <item name="android:textSize">30sp</item>
    <item name="android:layout_width">fill_parent</item>
    <item name="android:layout_height">150dp</item>
</style>

Just let one Style inherit from the other:

 <style name="bottomText" parent="TextStyle">
      <item name="android:layout_width">fill_parent</item>
      <item name="android:layout_height">150dp</item>
  </style>

the style "bottomText" then has all attributes defined in "TextStyle", but can still be overwritten within bottomText.

<style name="TextStyle">
    <item name="android:textSize">30sp</item>
</style>

<style name="bottomText" parent="@style/TextStyle">
  <item name="android:layout_width">fill_parent</item>
  <item name="android:layout_height">150dp</item>
</style>

<style name="boldText" parent="@style/bottomText">
  <item name="android:textStyle">bold</item>
</style>

Another approach:

<style name="bottomText.BoldText">
  <item name="android:textStyle">bold</item>
</style>

In last two cases boldText inherits from bottomText which defines android:layout_width and android:layout_height

text bold?? Is there bold attr on TextView in android? if you just want to set text attr, you can see this post http://stackoverflow.com/questions/3297437/shadow-effect-for-a-text-in-android/3297562#3297562 – Mejonzhan May 13 '13 at 13:33
Of course, there is a `bold` value for TextView's `android:textStyle` attribute. – mmBs May 13 '13 at 13:47

From what I can see, you don't need that second style since you need to set a layout_width and layout_height in the xml. You can just set that height and width when you create your layout and just use the style="@styles/TextStyle". If there's a reason you can't do it this way, please explain the problem a little better
