onClickListener cannot be resolved to a type and not applicable

Question

New to Java, using Eclipse. Except this error I also got some:

Description Resource Path Location Type The method onClick(View) of type new onClickListener

Answer 1

// replace this code
 button2.setOnClickListener(new OnClickListener() {
                @Override
                public void onClick(View v) {
                button2.setText("COŽE!?");
