Android :: Applying Style To Textview

I am trying to apply common style to different textview that can be either defined in a layout xml file or programmatically and that does not seem to work for some attributes: My style in styles.xml is:

<style name="ListName"> <item name="android:colorForeground">#f0f</item> <item name="android:padding">4sp</item> <item name="android:textSize">30sp</item> <item name="android:textColor">#CCC</item> <item name="android:gravity">left</item> <item name="android:typeface">serif</item> <item name="android:textStyle">bold</item> <item name="android:colorBackground">#999</item> </style>

In my layout xml i have <TextView style="@style/ListName" ...></ TextView> and in my activity java class i have: TextView nametv = new TextView(this,null,R.style.ListName); However some parameters does not seem to work very well: - textStyle to bolditalic does not seems to be recognized - textColor/colorForeground/colorBackground does not work at all. I have been through the documentation, but could not find precise reference documentation for that attributes, nor sample for the color setting.
