Java 如果项目名称相同，则Arraylist重复条目
我在代码中遇到了一个问题 场景是 从微调器添加项目时，它将添加到边列表中 在第一次按下订单按钮之前，其文本设置为蓝色，您也可以修改数量 -添加第二项 -按下订单按钮后，订单信息将发送到db，文本设置为黄色。订单下达后，您将无法修改项目 -现在，您可以向下一个订单添加一个不同的项目 -然后你下第二个订单 -如果你添加了相同的物品“摩根船长”，那么它就会添加到第二份订单中 下面是处理上述操作的所有代码 我使用两个片段main fragment和SideFragment SidePanelFragment.javaJava 如果项目名称相同，则Arraylist重复条目,java,android,listview,android-fragments,arraylist,Java,Android,Listview,Android Fragments,Arraylist,我在代码中遇到了一个问题 场景是 从微调器添加项目时，它将添加到边列表中 在第一次按下订单按钮之前，其文本设置为蓝色，您也可以修改数量 -添加第二项 -按下订单按钮后，订单信息将发送到db，文本设置为黄色。订单下达后，您将无法修改项目 -现在，您可以向下一个订单添加一个不同的项目 -然后你下第二个订单 -如果你添加了相同的物品“摩根船长”，那么它就会添加到第二份订单中 下面是处理上述操作的所有代码 我使用两个片段main fragment和SideFragment SidePanelFr

对于（int i＝0；i），在项目本身上设置标志<强>有序< /强>，单击一次就将其重置为false。您应该考虑在别处管理“强”>“命令< /强>”标志，而不是在引用项本身上。
错误代码
这个代码片段解决了这个问题
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
selectedItem=new Items();
Items getItms=(Items)parent.getItemAtPosition(position);
selectedItem.ItemCode=getItms.ItemCode;
selectedItem.ItemName=getItms.ItemName;
selectedItem.Price=getItms.Price;
selectedItemName=selectedItem.ItemName;
selectedItemPrice=selectedItem.Price;
itemName.setText(selectedItemName);
itemPrice.setText(String.valueOf(selectedItemPrice));
quantPlus.setEnabled(true);
quantMinus.setEnabled(true);
quantCount=1;
quantity.setText(String.valueOf(quantCount));
addItem.setEnabled(true);
// Toast.makeText(getActivity().getApplicationContext(),selectedItem, Toast.LENGTH_LONG).show();
}
});
list.setOnItemClickListener（新的AdapterView.OnItemClickListener（）{
@凌驾
public void onItemClick（AdapterView父对象、视图、整型位置、长id）{
selectedItem=新项目（）；
Items getItms=（Items）parent.getItemAtPosition（position）；
选择editem.ItemCode=getItms.ItemCode；
选择editem.ItemName=getItms.ItemName；

看着你的眼睛，我的眼睛很痛UI@RandykaYudhistira我知道，是的！UI颜色方案稍后会更改，但你知道有什么可以帮助我处理代码的吗？我不知道，我没有很好地阅读你的问题。问题太长，图片颜色最差。你能总结一下你的问题，只包括你的问题出现的时间和地点吗occur@RandykaYudhistira问题的最后一部分描述了这个问题，那么我应该将selectedItem.Ordered=false；？正如我所说的，我建议创建一个新的容器对象Order，它包含要排序的项目列表。selectedItem.Ordered属性应该移到Order对象。
