Horizontal field manager
A horizontal field manager is represented by the HorizontalFieldManager class. This layout manager arranges fields in a single horizontal row starting at the left side of the screen and ending at the right side of the screen. Because this layout manager is designed to arrange fields horizontally, you can apply vertical style bits, but not horizontal style bits, to the fields that this manager contains. For example, you can apply Field.FIELD_TOP, Field.FIELD_BOTTOM, or Field.FIELD_VCENTER style bits, but you cannot apply Field.FIELD_LEFT, Field.FIELD_RIGHT, or Field.FIELD_HCENTER style bits.
