startbutton و pausebutton رو میشناسه اما موقع اجرا روی setonclicklistener ها خطا میگیره

کافی است در فرگمنت کد مربوط به کلیک را اضافه کنید. یعنی:

public class Tab1Fragment  extends Fragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        View view = inflater.inflate(R.layout.fragment_blue, container, false);
        Button startbutton = (Button) view.findViewById(R.id.startbutton);
        startbutton.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                Log.i("log", "clicked");
            }
        });
        return view;
    }
}
