Java 无法在edittext中显示数据库中的数据

我正在制作一个表单FVPI.java。在表单中，我从数据库中获取数据，但无法在表单中显示。这是源代码表单FVPI.java。请帮忙

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    super.onSaveInstanceState(savedInstanceState);
    View v = inflater.inflate(R.layout.fvpi, null);
      dataSource = new DBDataSource(getActivity());
      dataSource.open();

      edtsales= (EditText) v.findViewById(R.id.txtsales);
      edttglpros= (EditText) v.findViewById(R.id.txttgl);
      edtnamacustomer= (EditText) v.findViewById(R.id.txtnamacustomer);
      edtalamat= (EditText) v.findViewById(R.id.txtalamat);
      edtarea= (EditText) v.findViewById(R.id.txtarea);
      edtcp= (EditText) v.findViewById(R.id.txtcp);
      edtnotelp= (EditText) v.findViewById(R.id.txtphone);
      edtemail= (EditText) v.findViewById(R.id.txtemail);
      edtowner= (EditText) v.findViewById(R.id.txtowner);
      edtdirector= (EditText) v.findViewById(R.id.txtdirector);
      edtgroupcompany= (EditText) v.findViewById(R.id.txtgroupcompany);

        Customer customer = dataSource.getCustomer(customerid);
        if(Globals.customerpros==null){
            Globals.customerpros=customer;
        }
        edtnamacustomer.setText(customer.getname());
        edtalamat.setText(customer.getAddress());
        edtarea.setText(customer.getArea());
        edtcp.setText(customer.getContactperson());
        edtnotelp.setText(customer.getPhoneno());
        edtemail.setText(customer.getCustomeremail());
        edtowner.setText(customer.getOwner());
        edtdirector.setText(customer.getDirector());
        edtgroupcompany.setText(customer.getGroupcompany());
        edkapasitaspros.setText(customer.getCapacity());

这是DBdatasource.java

public Customer getCustomer(String customerid){
        Customer Customer = new Customer();
        Cursor cursor = database.query(DBHelper.CUSTOMER, allCustomer, DBHelper.CUSTOMER_ID +"='cus1' ", null, null, null, null);
        cursor.moveToFirst();
        Customer = cursorToCustomer(cursor);
        cursor.close();
        return Customer;
    }

    private Customer cursorToCustomer(Cursor cursor)
    {
        Customer Customer = new Customer();
        Log.v("info", "The getString "+cursor.getString(cursor.getColumnIndex(DBHelper.CUSTOMER_ID)));
        Log.v("info", "The setLatLng " +cursor.getString(cursor.getColumnIndex(DBHelper.NAME))+","
                                       +cursor.getString(cursor.getColumnIndex(DBHelper.ADDRESS))+","

                                       +cursor.getString(cursor.getColumnIndex(DBHelper.CUSTOMER_EMAIL))+","

                                       +cursor.getString(cursor.getColumnIndex(DBHelper.DIRECTOR))+","
                                       +cursor.getString(cursor.getColumnIndex(DBHelper.GROUP_COMPANY))+","
                                       +cursor.getString(cursor.getColumnIndex(DBHelper.CAPACITY)));
        Customer.setcustomerid(cursor.getString(cursor.getColumnIndex(DBHelper.CUSTOMER_ID)));
        Customer.setname(cursor.getString(cursor.getColumnIndex(DBHelper.NAME)));
        Customer.setAddress(cursor.getString(cursor.getColumnIndex(DBHelper.ADDRESS)));
        Customer.setCity(cursor.getString(cursor.getColumnIndex(DBHelper.CITY)));
        Customer.setZipcode(cursor.getString(cursor.getColumnIndex(DBHelper.ZIPCODE)));
        Customer.setArea(cursor.getString(cursor.getColumnIndex(DBHelper.AREA)));
        Customer.setContactperson(cursor.getString(cursor.getColumnIndex(DBHelper.CONTACT_PERSON)));
        Customer.setPhoneno(cursor.getString(cursor.getColumnIndex(DBHelper.PHONE_NO)));
        Customer.setMobileno(cursor.getString(cursor.getColumnIndex(DBHelper.MOBILE_NO)));
        Customer.setCustomeremail(cursor.getString(cursor.getColumnIndex(DBHelper.CUSTOMER_ID)));
        Customer.setOwner(cursor.getString(cursor.getColumnIndex(DBHelper.OWNER)));
        Customer.setDirector(cursor.getString(cursor.getColumnIndex(DBHelper.DIRECTOR)));
        Customer.setGroupcompany(cursor.getString(cursor.getColumnIndex(DBHelper.GROUP_COMPANY)));
        Customer.setCapacity(cursor.getString(cursor.getColumnIndex(DBHelper.CAPACITY)));
        Customer.setOrderestimate(cursor.getString(cursor.getColumnIndex(DBHelper.ORDERESTIMATE)));
        Customer.setComplainer(cursor.getString(cursor.getColumnIndex(DBHelper.COMPLAINER)));
        return Customer;
    }

尝试这种方式（更改已标记） 顺便说一句，实例化一个新对象并将其命名为与类本身相同的名称是不好的做法，可能会导致过程中出现重大错误

代码中的主要问题是，您收到了一个名为“customerid”的字符串，但在光标中搜索这个“cus1”

公共客户getCustomer（字符串customerid）{
Customer Customer=new Customer（）；//我尝试了这一次，但仍然没有任何结果。是否有其他建议？是否确实更改了此行游标游标=database.query（DBHelper.Customer，allCustomer，DBHelper.Customer\u ID+“=”+customerid，null，null，null）；如a所说？这是samae。我使用了该方法，但什么也没发生。我建议您使用断点调试代码，以确保一切正常，因为我尝试了我向您展示的代码，如果程序中的其他所有内容都是正确的，那么这部分也应该是因为它在我的测试程序中运行良好
public Customer getCustomer(String customerid){
    Customer customer = new Customer();  //<--
    Cursor cursor = database.query(DBHelper.CUSTOMER, allCustomer, DBHelper.CUSTOMER_ID +"=" + customerid, null, null, null, null); //<--
    cursor.moveToFirst();
    customer = cursorToCustomer(cursor); //<--
    cursor.close();
    return customer; //<--
