Crash - TextView cannot be cast to button

Hello!

I'm having a bit of an issue with my app in the fact that I am unable to start it. I did a bit of Googling on the issue and found that if my code is TextView answerLabel = (Button) findViewById(R.id.textView1);

instead of

TextView answerLabel = (TextView) findViewById(R.id.textView1);

Then the error will occur.

//

The problem is, my code is like the bottom example and I can't understand what's causing the crash.

Here is my crash log: http://pastebin.com/tGfXktn3

Here is my MainActivity.java file: http://pastebin.com/kFa0MqrJ

Here is my activity_main.xml file: http://pastebin.com/mhPUgY9x

Any help would be much appreciated! :)

Hi!

Could you please paste your acitivity_main.xml file here as well, that would help on finding the cause of your error.

I have now updated my previous post to include my activity_main.xml file.

Thanks in advance!

Hi Harry!

I didn't find any errors in your project, I actually tried to create your project on my workspace, and it ran just fine. What you could do is clean your project using Eclipse, by clicking on Project->Clean... If that doesn't show any results, you can try uploading your project and sending me the link, I'll have a look at it :-)

Hello again!

Good news now, I have managed to track down the issue. It was in my AndroidManifest.xml.

I had my theme set to one that must no longer be supported by Android so, by updating it to Theme.base, I was able to fix the issue.

Appreciate your help anyway and for taking the time to find the issue (As, not everyone would do that).
