如何在 table 视图中填充数据，用户在 javaFX 中单击按钮时输入

Question

我已经在我的 fxml 文件中给出了正确的 id，但代码不起作用并且没有错误 too.i 想要以文本形式输入所有内容，并且在按下添加按钮时必须将该数据填充到 tableview.Input 是在选择行时转换为 string.and 的文本、单选按钮和复选框，必须在单击删除按钮时删除该行。

public class CashDrawerController implements Initializable 
{
   @FXML TextField UnitText;
   @FXML CheckBox NCCheck;
   @FXML TextField CurrencyText;
   @FXML  RadioButton BillRadio;
   @FXML RadioButton CoinRadio;
   String select="";
   String NC="N";
   @FXML TableView<Person> table;
   @FXML TableColumn<Person,String> unitcol ;
   @FXML TableColumn<Person,String> valuecol ;
   @FXML TableColumn<Person,String> typecol ;
   @FXML TableColumn<Person,String> nccol ;
  private finalObservableList<Person>data=FXCollections.observableArrayList(
                new Person("Jacob",  "Smith","jacob.smith@example.com","sadfdsf"),
                new Person("Isabella", "Johnson", "isabella.johnson@example.com","sdfsdaf"),
                new Person("Ethan", "Williams", "ethan.williams@example.com","adsfdsf"),
                new Person("Emma", "Jones", "emma.jones@example.com","dsfsad"),
                new Person("Michael", "Brown", "michael.brown@example.com","sdfsafd")
        );
@FXML
private void handleRemoveButtonAction(ActionEvent ev){

}
@FXML
private void  handleAddButtonAction(ActionEvent eve){
    if(BillRadio.isSelected()){
        select="Bill";
    }
    if(CoinRadio.isSelected()){
      select="Coin";
    }
    if(NCCheck.isSelected()){
        NC="Y";
    }        
   data.add(new Person(
            UnitText.getText(),
            CurrencyText.getText(),
            select,NC));
    UnitText.clear();
    CurrencyText.clear();
    Person obj=new Person("name1","val1","type","nc1");
    obj.setUnitName("name2");
    obj.setValue("val2");
    obj.setType("type2");
    obj.setNC("nc2");
unitcol.setCellValueFactory(new javafx.scene.control.cell.PropertyValueFactory<Person,String>("UnitName"));
  valuecol.setCellValueFactory(new javafx.scene.control.cell.PropertyValueFactory<Person,String>("Value"));


 typecol.setCellValueFactory(new javafx.scene.control.cell.PropertyValueFactory<Person,String>("Type"));



nccol.setCellValueFactory(newjavafx.scene.control.cell.PropertyValueFactory<Person,String>("NC"));  

}

@Override
public void initialize(URL url, ResourceBundle rb) {            

}    


public static class Person {

    private final SimpleStringProperty UnitName;
    private final SimpleStringProperty Value;
    private final SimpleStringProperty Type;
     private final SimpleStringProperty NC;
    private Person(String uName, String val, String type,String nc) {
        this.UnitName = new SimpleStringProperty(uName);
        this.Value = new SimpleStringProperty(val);
        this.Type = new SimpleStringProperty(type);
        this.NC = new SimpleStringProperty(nc);
    }

    public String getUnitName() {
        return UnitName.get();
    }

    public void setUnitName(String uName) {
        UnitName.set(uName);
    }

    public String getValue() {
        return Value.get();
    }

    public void setValue(String val) {
        Value.set(val);
    }

    public String getType() {
        return Type.get();
    }

    public void setType(String type) {
        Type.set(type);
    }

    public String getNC(){
        return NC.get();
    }

    public void setNC(String nc){
        NC.set(nc);
    }
}

}

Answer 1

你不需要每次点击都设置cell factory，可以把所有setCellValueFactory放在initialize

public void initialize(URL url, ResourceBundle rb) { 
    unitcol.setCellValueFactory(new PropertyValueFactory<Person,String>("UnitName"));
    valuecol.setCellValueFactory(new PropertyValueFactory<Person,String>("Value"));
    typecol.setCellValueFactory(new PropertyValueFactory<Person,String>("Type"));
    nccol.setCellValueFactory(new PropertyValueFactory<Person,String>("NC")); 
}

你还需要每次在 handleAddButtonAction 中设置 NS 我认为：

if(NCCheck.isSelected()) NC="Y";
else NS ="N"

最重要的部分，我没看到你在哪里设置你的数据到table：在initialize中添加这个table.setItems(data);

这是一个示例，在 Initialize 方法中我有 setCellValueFactory，并且我通过 Mytable.setItems 方法将项目（可观察列表）分配给 table：
