void setSwitchTextOff (int resId)

Set the text displayed on the switch widget in the off state. This should be a very short string; one word if possible.

Parameters
`resId`	`int`: The text as a string resource ID

setSwitchTextOff

void setSwitchTextOff (CharSequence offText)

Set the text displayed on the switch widget in the off state. This should be a very short string; one word if possible.

Parameters
`offText`	`CharSequence`: Text to display in the off state
