Using custom attrs in styles.xml in android

[ideompirm]

I made a custom attribute style as\[code\]<?xml version="1.0" encoding="utf-8"?><resources> <declare-styleable name="EffectsTextView"> <attr name="strokeWidth" format="float" /> <attr name="strokeMiter" format="float" /> <attr name="strokeColor" format="color" /> </declare-styleable></resources>\[/code\]In Layout file, I could use this custom attribute assigning a namespace for this attribute:\[code\]<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:effects="http://schemas.android.com/apk/res-auto/com.base.view.EffectsTextView"android:layout_width="fill_parent"android:layout_height="fill_parent"android:background="#40000000" > <com.base.view.EffectsTextView android:id="@+id/textView1" android:layout_width="290dip" android:layout_height="80dip" android:layout_marginLeft="5dip" android:layout_marginTop="16dip" android:gravity="center" android:text="SETTINGS" android:textSize="44dip" android:textStyle="bold" effects:strokeWidth="10" /> <--- custom tag "effects"\[/code\]However it was not recognizing this custom tag in styles.xml\[code\]<style name="EffectsHeaderTextStyle"> <item name="effects:strokeWidth">10</item></style>\[/code\]Error: No resource found that matches the given name, effects, though I put the namespace same as I did in RelativeLayout file. Any ideas? Thanks
