[android-developers] Re: EditText.getText() not working
using findViewById() 81 times seems more demanding than creating them
at runtime to me.
There is always an Exception thrown if your app is crashing, look at
the logcat in the 'DDMS' view in Eclipse.
If you only see a runtime exception then you need to get the cause
from the exception. Surround the call with a try-catch and use
something like this:
catch (Exception e)
{
final static String TAG = "you app name";
StackTraceElement[] arr = e.getStackTrace();

[android-developers] Re: EditText.getText() not working
I have tried doing the EditTexts programatically in a loop. No luck. Still gives me the same problem. I am having a hard time trying to figure out what the exact problem is. I am new to the eclipse IDE and the android programming.

[android-developers] Re: EditText.getText() not working
Yes I did check for null. It is not the null exception. I am having problems finding out what kind of an error it is. There is no error in the code. The program stops in the middle while running. "Why don't you generate your EditTexts programmatically in a double loop?" That is a good idea but I was going through the documentation and it was suggested that we use the xml for doing the GUI. Though the 81 objects can be dynamically generated wouldn't that make the app slower? Well anyway, I will try doing that dynamically and see if that fixes my problem. Thank you for the reply.
