Android Question Hide button text when not in accesibility mode

[hookshy]

When dealing with accesibility mode you must define button texts to help user find buttons .....otherwise the navigations in accesibility mode sounds like this:
Button , button , button ....and so one

I need to set btn.text="Volume" and then hide text , and keep only visual background.

How can I hide the text button ?

Thanks

maybe copy text in into tag and make text empty?
normal you can hide only the control via .Visible=False
why you need buttons with background and without text? just for optic?
