Question

我在vim中使用相对行号设置。我希望vim在我处于插入模式时自动切换到绝对行号，并在正常模式下返回到相对。目前我已经在我的vimrc

中尝试了这段代码

  autocmd InsertEnter * :set number                                                                                                                                                                                                      
  autocmd InsertLeave * :set relativenumber

不幸的是，这只会让我成为那里的一部分。这在我第一次离开插入模式时切换相对数字，但在再次进入插入模式时将不再返回绝对数字。

Answer 1

首先，做一个

autocmd InsertEnter * :set norelativenumber
autocmd InsertLeave * :set relativenumber

然后

    public class FCar extends Fragment implements AdapterView.OnItemSelectedListener {

    public FCar() {
    }

    CarDataBaseAdapter carDataBaseAdapter;
    SessionManagement session;

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

//        inflating the view
        final View rootView = inflater.inflate(R.layout.fragment_car, container, false);
//        declaring stuff, not sure why it has to be final
        final Spinner carSpinner;
        final EditText editTextDistance, editTextMin;
        Button btnSubmitCar;

//      create new car database
        carDataBaseAdapter = new CarDataBaseAdapter(getActivity());
        carDataBaseAdapter = carDataBaseAdapter.open();
        SQLiteDatabase x = carDataBaseAdapter.getDatabaseInstance();

        session = new SessionManagement(getActivity().getApplicationContext());

//        display existing tables
/*
        Cursor hi = x.rawQuery("SELECT name FROM sqlite_master WHERE type='table'", null);
        hi.moveToFirst();
        int f = hi.getCount();
        String g = Integer.toString(f);
        Toast.makeText(getActivity().getApplicationContext(), g, Toast.LENGTH_LONG).show();
        while ( !hi.isAfterLast() ) {
            String h = (hi.getString( hi.getColumnIndex("name")) );
            hi.moveToNext();
            Toast.makeText(getActivity().getApplicationContext(), h, Toast.LENGTH_LONG).show();
        }

        // Get References of Views
        carSpinner = (Spinner) rootView.findViewById(R.id.spinner_car_type);
        editTextDistance = (EditText) rootView.findViewById(R.id.editTextcarDistance);
        editTextMin = (EditText) rootView.findViewById(R.id.editTextcarMin);

        // Spinner click listener

                                                String username = session.getUsername();

                                                SimpleDateFormat formata = new SimpleDateFormat("MM/dd/yyyy", Locale.CANADA);
                                                String date = formata.format(new Date());

                                                String type = carSpinner.getSelectedItem().toString();

//                convert distance to integer
                                                int distance = 0;

                                                int time = 0;

                                                }

                                                // Save the Data in Database
                                                carDataBaseAdapter.insertEntry(username, date, type, distance, time);

                                        }
        );
        return rootView;
    }

Answer 2

set number

map <Esc> :set relativenumber!<CR>

点击该键应该切换行相对编号

通过插入/正常模式切换VIM中的绝对编号和相对编号
