JavaFX TableView提供值

Question

我得到一个问题，填充tableview的值。我试过JavaFX TableView dynamic column and data values 的解决方案，但这并不适合我。这是代码。如果有人知道如何解决这个问题，这将是非常好的。

public class CSVTableViewer extends Application { 

private String allColumns; 
private FileSource fileSource; 
BufferedReader in; 
private String zeile; 
private String reihe; 
private String[]rowsArray; 
private String a=""; 
private String result2; 

ArrayList<String> c=new ArrayList<String>(); 
List<List<String>> data; 

/** 
* @return the zeile 
*/ 
public String getZeile() { 
    return zeile; 
} 



public void start(Stage stage) throws IOException { 
    TableView tableView = new TableView(); 
    Pattern p = Pattern.compile("[;\\/|\\t]"); 
    Pattern p2 = Pattern.compile("[\\s\\s]"); 
    //DataSourceReader dsr1 = new FileSource("your csv file path"); 
    String input = Dialogs.showInputDialog(stage, "Please enter path to csv:", "Input 
    Dialog", "Input Path"); 
    try{ 
    this.fileSource = new FileSource(input);  
    in = new BufferedReader(new FileReader(input)); 
    allColumns=in.readLine(); 
    }catch(IOException e){ 
     Dialogs.showErrorDialog(stage, "No CSV-File Found"); 
     System.exit(0); 
    } 


// Pattern p = Pattern.compile("[;\\.,/|.\\t]"); 
    String[] columnsArray=p.split(allColumns);// create array of column names you want to 
    display 
    for(int i=0;i<columnsArray.length;i++){ 
// a.add(columnsArray[i]); 

    } 

    CSVDataSource ds1 = new CSVDataSource(this.fileSource,columnsArray); 
    //TableView tableView = new TableView(); 
// tableView.setItems(ds1.getData()); 
    tableView.getColumns().addAll(ds1.getColumns()); 
    tableView.setColumnResizePolicy(TableView.CONSTRAINED_RESIZE_POLICY); 





    try { 
     while ((reihe = in.readLine()) != null) { 

      String[]row=p.split(reihe); 


      // System.out.println(als); 


     for (int i = 0; i < row.length; i++) { 
      String result=row[i].toString(); 
      c.add(result); 

     }} 




     }catch (IOException ex) { 
     Logger.getLogger(CSVTableViewer.class.getName()).log(Level.SEVERE, null, ex); 



     } 

     /*

     row.add(rowData); 
     } 
    /add each row to cvsData 
    } 

    tableView.setItems(csvData); 
    */ 
    /* Fills 'columns' and 'data' */ 





// zeile=in.readLine(); 
// System.out.println(zeile); 
// rowsArray=p.split(zeile); 





    //TableView tableView = new TableView(); 
    // tableView.setItems(musics);

    ObservableList<String> row = FXCollections.observableArrayList(); 
    for(String rowData : c) { 
    row.add(rowData); 

    // add each row to cvsData 
    }

在yourCarryObject类：

public ObservableList<String> getData() { 
    ObservableList<String> ostr = FXCollections.observableArrayList(); 

    ostr.clear(); 
    for (int i = 0; i < row.length; i++) { 
     String result=row[i].toString(); // if you are importing data from that row array 
     ostr.add(result); 
    } 
    return ostr; 
} 

后来

table.setItems(yourCarryObject.getData());
