Adds a layout rule to be interpreted by the RelativeLayout. This
method should only be used for constraints that don't refer to another sibling
(e.g., CENTER_IN_PARENT) or take a boolean value (TRUE

anchor | The id of another view to use as an anchor,
or a boolean value(represented as TRUE )
for true or 0 for false). For verbs that don't refer to another sibling
(for example, ALIGN_WITH_PARENT_BOTTOM) just use -1. |
Returns a String representation of this set of layout parameters.
output | the String to prepend to the internal representation |
