Defined in the style as follows:
<style name= "MyStyle" >
<item name= "Android.windownotitle" >true</item><!--no title-->
<item name= "Android.windowfullscreen" >true</item><!--full screen, if you want to change the value with a value change, you can use the way to reference-->
<!--For example: to refer to the value of a caption, you can set the value to: "Android:windownotitle"-->
If you want the entire app to be the same, you can change the Androidmanifest.xml and refer to the style on application:
<application android:theme= "@style/mystyle"
If you just want to act on an activity, then change the theme of one of the actions.
