You can customize your window features by using @WindowFeature on an enhanced activity. The annotation value should be one or several of Window FEATURE_* constants.

@WindowFeature({ Window.FEATURE_NO_TITLE, Window.FEATURE_INDETERMINATE_PROGRESS })
@EActivity
public class MyActivity extends Activity {
 
}

Since AndroidAnnotations 2.2

This annotation adds the Window flag LayoutParams.FLAG_FULLSCREEN.

@Fullscreen
public class MyActivity extends Activity {

}
