我在我的单元格列没有填充任何东西的问题。以下是我的代码：GWT - celltable
public class CellTableExample implements EntryPoint {
private static class Contact
{
private String address;
private String name;
private String phone="";
public Contact(String name, String address, String phone) {
super();
this.address = address;
this.name = name;
this.phone=getPhoneNumber(name);
}
}
public String getPhoneNumber(String name)
{
String pNum="";
SQLRunnerAsync service = (SQLRunnerAsync) GWT.create(SQLRunner.class);
AsyncCallback<String> callback = new AsyncCallback<String>()
{
@Override
public void onFailure(Throwable caught)
{
}
@Override
public void onSuccess(ArrayList<String[]> result)
{
pNum=reuslt;
}
};
service.findPhoneNum(name,callback);
return pNum;
}
// The list of data to display.
private static List<Contact> CONTACTS = Arrays.asList(
new Contact("John", "123 Fourth Road asdf asdf asdfasdf"),
new Contact("Mary", "222 Lancer Lane")
);
@Override
public void onModuleLoad() {
CellTable<Contact> table = new CellTable<Contact>();
SQLRunnerAsync service = (SQLRunnerAsync) GWT.create(SQLRunner.class);
AsyncCallback<ArrayList<String[]>> callback = new AsyncCallback<ArrayList<String[]>>()
{
@Override
public void onFailure(Throwable caught)
{
}
@Override
public void onSuccess(ArrayList<String[]> result)
{
compFlexTable.setPageSize(result.size());
Contact[] contactArr = new Contact[result.size()];
for(int i=0;i<result.size();i++)
{
String [] temp = result.get(i);
String name=temp[0];//name
String address=temp[1];//address
contactArr[i]=new Component1(name,address);
}
COMPONENT=Arrays.asList(compArray);
//address column
TextColumn<Contact> addressColumn = new TextColumn<Contact>(){
@Override
public String getValue(Contact contact) {
return contact.address;
}
};
//name column
TextColumn<Contact> nameColumn = new TextColumn<Contact>(){
@Override
public String getValue(Contact contact) {
return contact.name;
}
};
//name column
TextColumn<Contact> phoneColumn = new TextColumn<Contact>(){
@Override
public String getValue(Contact contact) {
return contact.phone;
}
};
service.getContactInfo(callback);
// Add the columns.
table.addColumn(nameColumn, "Name");
table.addColumn(addressColumn, "Address");
table.setRowCount(CONTACTS.size(), true);
table.setRowData(0, CONTACTS);
RootPanel.get().add(table);
}
}
所以，当我创建一个联系对象，另一种异步方法被调用，以获取联系人的电话号码。表格显示正常，但电话号码列为空。我该如何解决这个问题？任何意见/建议将不胜感激..非常感谢。
