Hey guys, new to the forum
I had a question on a piece of my code..
What I'm trying to do is learn how to set a TextView's default text to whatever I edit in the EditText
In Lamence terms..
Default Text <---Label
[Default Text] <---Text Box
[Change] <---Button
If I change the information in the Text Box, it will change the Label on the Change Button click..
Now, it will change the text to 'false' and I can't figure out what I'm doing wrong..
Here's my Main.java:
and here's my main.xml
Thanks a bunch guys If you have any questions on what I'm trying to do feel free to question, I know it's kinda hard to understand with my ASCII drawing ..
