Java “如何通过选定的家长”；“子元素”；从一个自定义适配器到另一个新的自定义适配器？
在可扩展的自定义适配器中，我有一个带有复选框和子元素的自定义适配器，当选中/选中“我的案例订单”的父项时，订单将传递给一个新的自定义适配器，而不带复选框。我可以传递父ie订单，但无法传递子元素ie项目，即订单的子目录。因此，我需要将所选订单的子元素传递给新的适配器视图。 我的代码：Java “如何通过选定的家长”；“子元素”；从一个自定义适配器到另一个新的自定义适配器？,java,android,android-layout,android-listview,Java,Android,Android Layout,Android Listview,在可扩展的自定义适配器中，我有一个带有复选框和子元素的自定义适配器，当选中/选中“我的案例订单”的父项时，订单将传递给一个新的自定义适配器，而不带复选框。我可以传递父ie订单，但无法传递子元素ie项目，即订单的子目录。因此，我需要将所选订单的子元素传递给新的适配器视图。 我的代码： try { System.out.println("READ/PARSING JSON");

任何帮助都将是巨大的我通过for循环解决了这个问题，它将子项添加到新的“mOpenOrderSelected”变量中：
if (objOpenOrders.isChecked()) {
isSelectedOrderNumber++;
sb.append(objOpenOrders.getOrderID());
sb.append(",");
final OpenOrders parent = new OpenOrders(objOpenOrders.getOrderID(),objOpenOrders.getOrderName());
ArrayList<Child> mOpenOrderItems=objOpenOrders.getChildren();
parent.setChildren(new ArrayList<Child>());
for(int k=0; k<mOpenOrderItems.size(); k++){
final Child child = (Child) mOpenOrderItems.get(k);
Log.d("ChildItemsname", "ChildItemsname:"+child.getName());
parent.getChildren().add(child);
}
mOpenOrdersSelected.add(parent);
}
if（objOpenOrders.isChecked（））{
isSelectedOrderNumber++；
sb.append（objOpenOrders.getOrderID（））；
某人加上（“，”）；
最终OpenOrders父项=新OpenOrders（objOpenOrders.getOrderID（），objOpenOrders.getOrderName（））；
ArrayList mOpenOrderItems=objOpenOrders.getChildren（）；
