Any suggestions on why I am getting the "false" reading --> in the xml , set the button propert android:clickable" as true,
anyone can suggest on how to place the results in a TextView via a button click, that would be appreciated. as i can c u have the listener to the button, on click can u be specific what exact result u need? wether u need to change the text... etc. u can use tv.XXXXXXX specifically to change the required properties On Aug 28, 8:28 pm, rb <rbs...@gmail.com> wrote: > As a newbie, I have been reading posts in learning how to do different > functions.
