I have been following along with the book making a 2.1 application and all of the code minus one gravity xml change has worked so far.
Then i went to do the about.java part and had a problem. Not knowing how to fix it, I created a new project 1.6 and copied all of my code/xml/folders.
The same problem still exists so I have no idea what to do.
//Set up click listeners for all of the buttons
View continueButton = findViewById(R.id.continue_button);
continueButton.setOnClickListener(this);
View newButton = findViewById(R.id.new_button);
newButton.setOnClickListener(this);
View aboutButton = findViewById(R.id.about_button);
aboutButton.setOnClickListener(this);
View exitButton = findViewById(R.id.exit_button);
exitButton.setOnClickListener(this);
when highlighting over the setOnClickListener which is an error on all 4 lines, it says, “The method setOnClickListener(View.OnClickListener) in the type View is not applicable for the arguments (Sudoku)”
Please help if you can. Thanks so much in advance.
