将ArrayList 转换为ObservableList(Convert ArrayList to ObservableList)

将ArrayList 转换为ObservableList(Convert ArrayList to ObservableList)

我想将ArrayList<HashMap>转换为ObservableList并将其放在我的TableView 。 将项放在TableView ，它只是不显示HashMap的值。 因此，对于具有6项目的ArrayList ，表中显示了6行，但单元格包含空值。

这是我有的：

@FXML TableView dataTable; //... Other code ...// ArrayList<HashMap> items = currentMysqlConn.getTableData(databaseName, tableName, 1000); ObservableList<HashMap> oblist = FXCollections.observableArrayList(items); dataTable.setItems(oblist); //... Other code ...//

I would like to convert an ArrayList<HashMap> to an ObservableList and place it in my TableView. Placing the items in the TableView works, it just doesn't display the values from the HashMap. So, for an ArrayList that has 6 items, 6 rows show in the table, but the cells contain empty values.

Here is what I have:

@FXML TableView dataTable; //... Other code ...// ArrayList<HashMap> items = currentMysqlConn.getTableData(databaseName, tableName, 1000); ObservableList<HashMap> oblist = FXCollections.observableArrayList(items); dataTable.setItems(oblist); //... Other code ...//

最满意答案

我能够得到它！
