Create style inheriting properties from another style

Refer to the style of last post Create style using Android Resources Tools, we can create a new style(MyStyle.GreenBold) inheriting properties from another existing style (MyStyle).

Modify /res/values/strings.xml, add a new style "MyStyle.GreenBold" inherit properties from "MyStyle", change and add properties of "android:textColor" and "android:textStyle".

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="MyStyle">
        <item name="android:layout_width">wrap_content</item>
        <item name="android:layout_height">wrap_content</item>
        <item name="android:textColor">#AAA</item>
        <item name="android:textSize">18dip</item>
        <item name="android:background">#222</item>
        <item name="android:padding">5dip</item>
    </style>
    <style name="MyStyle.GreenBold">
        <item name="android:textColor">#00FF00</item>
        <item name="android:textStyle">bold</item>
    </style>
</resources>

Modify main.xml adding TextView using new style of "MyStyle.GreenBold".

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="@string/hello" />
    <TextView
        style="@style/MyStyle"
        android:layout_width="fill_parent"
        android:text="it's text using style" />
    <TextView
        style="@style/MyStyle.GreenBold"
        android:layout_width="fill_parent"
        android:text="it's text using style of MyStyle.GreenBold" />
</LinearLayout>
