Alternative to Manager.firstFocus(int)
Manager#firstFocus(int direction) is undocumented and does not function on all OS platforms (like 5.0.0). Instead you can override Field#onFocus(int direction) and call Fields#firstFocus(Field field).
protected void onFocus( int direction ) { super.onFocus( direction ); Fields.firstFocus( getInputBoxField() ); }
For further control you can use the direction variable to determine if you are scrolling up (positive) or down (negative).
