I having trouble with my code I add the views and my code went crazy the editor says I have 8 errors

private CrystalBall2 mCrystalBall = new CrystalBall2();

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    // Declare our View variables and assign them the Views from the layout file
    final TextView answerLabel = (TextView) findViewById(R.id.textView1);
    Button getAnswerButton = (Button) findViewById(R.id.button1);

    getAnswerButton.setOnClickListener(new View.OnClickListener() {

        public void onClick(View arg0) {
            String answer = mCrystalBall.getAnAnswer();

            // Update the label with our dynamic answer
            answerLabel.setText(answer);
        }
    });
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.activity_main, menu);
    return true;
}


    });
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

}

1) answerLabel.setText( answer.getText( ).toString( ) );

2) Delete the bottom onCreateOptionsMenu( ) method starting at @Override just above it and everything else below

3) You apparently declared a View object of type TextView. Delete that.

4) activity_main is not the name of your xml file under ../res/layouts/

5) Go to that folder. Three scenarios...See below

5a) You did name your layout that.

 5b) You don't even have a layout.

 5c) You named your xml layout file something other than "main_activity"

6) if scenario = 5a then do next step | | if scenario = 5b skip next step and do step 7 | | if scenario = 5c skip next two steps and do step 8

7) Press ctrl+s, then in toolbar up top left click project->clean->clean all projects, then go back to your .java file and press ctrl+shift+O, ctrl+s, //DONE

8) Make your layout file and try again. Make sure you name it main_activity.xml //DONE

9) go back to your .java file and replace setContentView(R.layout.main_activity); with setContentView(R.layout.<name of your xml file ); //CONTINUE

10 ) If you just finished step 9 go back two steps to number 7. //CONTINUE

Could you tell us what those errors are?
From what I can infer at this point you can check if

  • you imported the library files for Button and TextView

  • made a typo error in some other place in the program

activity_main cannot be resolved or is not a field Multiple markers at this line - Line breakpoint:MainActivity [line: 21] - onCreate(Bundle) - textView1 cannot be resolved or is not a field

activity_main cannot be resolved or is not a field

Duplicate method onCreateOptionsMenu(Menu) in type MainActivity

main cannot be resolved or is not a field
