在一个副项目上工作，试图遍历一个弹性表并提取数据。该表有一列，其中包含另一个表，该表跨越与其关联的行的行。我首先获取该数据，然后获取与其关联的行，将其填充到程序集中，然后将其存储在 arraylist 中。我的问题是当它正确提取数据时，它没有存储到数组列表中。它覆盖了前面的所有行，我不知道为什么。这是 while 循环的范围问题吗？我没有正确声明某些东西吗？代码如下
private static void submitOrder() {
if (nullCheck()) {
ArrayList<AssemblyLine> assemblyLines = new ArrayList<AssemblyLine>();
HorizontalPanel hPanel = (HorizontalPanel) fTable.getWidget(fTable.getRowCount() - 1, 0);
CheckBox cb1 = (CheckBox) hPanel.getWidget(0);
int rowSpan = 0;
int currentRow = 1;
int currentAssemblyLineRow = 1;
while (currentRow < fTable.getRowCount() - 2) {
// get current info table and set initial data
FlexTable currentInfoTable = (FlexTable) fTable.getWidget(currentRow, 7);
rowSpan = fTable.getFlexCellFormatter().getRowSpan(currentRow, 7);
AssemblyLine al = new AssemblyLine();
ListBox assembler = (ListBox) currentInfoTable.getWidget(2, 1);
DateBox date = (DateBox) currentInfoTable.getWidget(3, 1);
al.setAssemblerName(assembler.getValue(assembler.getSelectedIndex()));
al.setDate(date.getValue());
al.setAssemblyID(Integer.parseInt(fTable.getHTML(currentRow, 0)));
// if "use all info for lots" is checked set assembler and date
// to that
//other data set here
// iterate through related rows and store assemblylines in
// database, I think the error is in here
while (currentAssemblyLineRow < (rowSpan + currentRow)) {
al.setQuantity(Integer.parseInt(fTable.getHTML(currentAssemblyLineRow, 5)));
System.out.println("al.getQuantity: " + al.getQuantity());
ListBox lb = (ListBox) fTable.getWidget(currentAssemblyLineRow, 6);
al.setPartLotNumber(lb.getItemText(lb.getSelectedIndex()));
System.out.println("al.getPartLotNumber: " + al.getPartLotNumber());
assemblyLines.add(al);
System.out.println("al.tostring: " + al.toString());
System.out.println("a.tostring: " + assemblyLines.get(assemblyLines.size() - 1).toString());
currentAssemblyLineRow++;
}
for (int k = 0; k < assemblyLines.size(); k++) {
System.out.println("a.tostring: " + k + " " + assemblyLines.get(k).toString());
}
// then iterate to next infotable
currentRow = currentRow + rowSpan;
}
DatabaseUtils.submitAssemblyLines(assemblyLines);
} else {
Window.alert("Oops! please fill out all boxes!");
}
}
这是控制台的输出
