import com.example.airmonitor.R;

public class MineFragment extends Fragment {

    public View onCreateView(@NonNull LayoutInflater inflater,ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_mine, container, false);

        return view;
    }

    //视图控件请在这里实例化
    //活动创建之后才能对fragment中的控件进行实例化，对控件的实例化、对控件的操作要在这个活动中完成
    @Override
    public void onActivityCreated(@Nullable Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);

        RelativeLayout mine1 = getActivity().findViewById(R.id.mine1);
        mine1.setOnClickListener(new View.OnClickListener() {
            @Override

                startActivity(i);
            }
