setText
Updates the message to be displayed to the end user. If no message is currently being displayed the provided message will begin animating in immediately, otherwise the message will be cached until the current message is no longer shown. Multiple calls to setText() during a single message's duration will only show the last message when the current message's duration is over.
An accessibility announcement is made when a new hint is displayed. The announced message will match newText, unless setContentDescription specified a message before.
NOTE: calling this method while isDelayingInitialHint is true will not update the message.
Parameters
The message to display. If the message is null or empty the View visibility will change to View.GONE and won't animate. If the message is not null and is not empty, the visibility will change to View.VISIBLE and will animate. This change will take effect when the new message is ready to display.
