Question

我正在开发基于Odoo框架的android应用程序。当用户选择称为补偿的休假类型时，我需要显示“补偿休假”字段，这是“多对多”字段类型。

我尝试了一些代码，但是当我将“多对多”字段绑定到XML时遇到错误：

这是我在xml中尝试过的代码

  <odoo.controls.OField
                        android:id="@+id/com_off_ids"
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        android:layout_weight="0.5"
                        app:fieldName="compoff_ids"
                        app:fieldTextAppearance="?android:textAppearanceMedium"/>

这是HrHolidays的odoo模型

OColumn employee_id = new OColumn("Employee", HrEmployee.class, OColumn.RelationType.ManyToOne);
    OColumn department_id = new OColumn("Department", HrDepartment.class, OColumn.RelationType.ManyToOne);
    OColumn company_id = new OColumn("Company", ResCompany.class, OColumn.RelationType.ManyToOne);
    OColumn holiday_type = new OColumn("Mode", OSelection.class).addSelection("employee", "By Employee").addSelection("category", "By Employee Tag");
    OColumn type = new OColumn("Type", OSelection.class).addSelection("remove", "Remove").addSelection("add", "Add").setDefaultValue("remove");
    @Odoo.Domain("[['line_id', '=', @leave_year_id]]")
    @Odoo.onChange(method = "partnerIdOnChange")
    OColumn holiday_status_id = new OColumn("Leave Type", HrHolidayStatus.class, OColumn.RelationType.ManyToOne);
    OColumn leave_year_id = new OColumn("Leave Year", LeaveYear.class, OColumn.RelationType.ManyToOne);
    OColumn compoff_ids = new OColumn("",CompLeaveRel.class, OColumn.RelationType.ManyToMany).setRelBaseColumn("leave_id").setRelRelationColumn("comp_id").setRelTableName("comp_leave_rel");

上面的代码“ Compoff_ids”字段中是“多对多”字段，我需要存储这些值。

这是CompLeaveRel模型字段

OColumn name = new OColumn("", OVarchar.class);
OColumn leave_id = new OColumn("", OVarchar.class);
OColumn comp_id = new OColumn("",OVarchar.class);

这是我将OColum绑定到XML小部件时遇到的错误：

     Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'int odoo.controls.OField$FieldType.ordinal()' on a null object reference

任何人都可以告诉我如何在odoo移动框架中使用和获取多对多字段的数据。

自从过去两天以来，我一直在这里被封锁

对不起，我的英语。

您可以将列定义为：

OColumn column_name = new OColumn("Description", table_name.class, OColumn.RelationType.ManyToMany);

，并使用与CRM应用中相同的结构来显示一个one2many字段（ExpandableListControl及其Adapter）或类似简单标签的内容。
