Android auto save data upon scan result

I have an android app that lets me scan barcodes and it saves to csv upon pressing a save button.
Would it be possible for me to auto-save data upon the scan result of a certain column?
So in short save after scan initiated in a certain edit text location.

Error Log:
After that, I got some error like :
"Error:(156, 10) error: reached end of file while parsing"
or
"Error:Execution failed for task ':app:compileDebugJavaWithJavac'."
So now I don't now how to solve that.

If this is your full code then your onClick method has not ending curly bracket and also your main class is not ended with curly bracket.
so add two ending curly braces at end of your code
