android temperature tutorial

[iamalex]

Working on the android temperature tutorial (the first one) and
getting errors in convert.java

In the following lines I'm getting "EditText01, Button01,
RadioButton01, RadioButton01" cannot be resolved or is not a field.

I put in exactly as tutorial said and main is fine, shows no errors.

Can someone please help.

thanks....alex

code where prolbmes show:


text = (EditText) findViewById(R.id.EditText01);

case R.id.Button01:
RadioButton celsiusButton = (RadioButton)
findViewById(R.id.RadioButton01);
RadioButton fahrenheitButton = (RadioButton)
findViewById(R.id.RadioButton02);

Did you run Project -> Clean?

You have to make certain you get the right R class. That's one of the
initially perplexing things about Android tutorials. You might get some
help reading this:

Hi Russel,

Thanks for your extension of my Android Tutorial. I think the following is funny: Quote: "As his expression is succinct and sometimes lacking in explanation" :-)

Cheers, Lars

I especially meant no insult. Your tutorials have been very important to me. Writing an article helps me to learn something well. I hit on the idea of "reviewing" your tutorial giving me a place to go back to if I get stuck. Sometimes I can refer others there if there's a specific point.

I wrote an article on servlets, JSPs and setting up and using Eclipse three years ago when I was learning to do such things. The Eclipse community published it. To write such a tutorial is a great deal of work, as you well know. And only to rewrite what you've already done so well seems pointless. So, I'm not going to write a tutorial on Android, REST, JSF (maybe not, I'm still thinking about it), etc. since it's already been done so well by you.

Yes, I'll submit suggestions and corrections to you. I have once or twice, but it's true I haven't made a habit of it.

My Android article already needs to be rewritten. I've learned a lot since I wrote it.

Very best regards,

Russ

Hi Russ,

no worry, no insult taken. :-)

I really like your addition and I think it is really cool that you extend my explanation. I also try to keep my tutorials as good as my time permits and therefore I'm happy if I see feedback on them

Thanks again.

Best regards, Lars

Bye the way: I have now a small familiy of Android tutorials which you find here: http://www.vogella.de/android.html

Hello, I think Im getting the same problem as Alex. Everywhere "text"
is used, an error is displayed, saying "text cannot be resolved." or
"text cannot be resolved to a variable".

I have tried Project>Clean... have read through Russel's article and
I'm still confused.

Hi Jamens,

can you post the coding where you see errors? Please also post your main.xml.

Best regards, Lars
