无尽适配器，单击加载..行将给出异常

Question

我刚刚在测试这个，如果用户在显示临时"loading…"行时按下它，它将给出越界异常。处理这个问题的最佳方法是什么？检查列表OnItemCLickListener上的id？

问候，

下面是listview项目监听器：

actualListView.setOnItemClickListener(新建OnItemClickListener（）｛

                @Override
                public void onItemClick(AdapterView<?> parent, View view,
                        int position, long id) {
                    IpdmsMobileMenuItemListDTO dto=(IpdmsMobileMenuItemListDTO) parent.getItemAtPosition(position);
                    if(getView().findViewById(R.id.myprocessdetail)!=null)
                        updateProcess((MyProcessDTO) dto.getDto());
                    else{
                        mListener.onMyProcessSelected((MyProcessDTO) dto.getDto());
                    }
                }
            });

这是堆栈跟踪：

它是在方法中的位置获取项目的行：

parent.getItemAtPosition（position）

我已经在onItemClick:中添加了这个条件

if(view.findViewById(R.id.loading_view)!=null){
                        //if its the loading row we wont do anything
                        return; 
                    }

从策略上讲，您需要通过检查position并查看您是否在最后一行来过滤掉它。

我将为EndlessAdapter制作一个补丁，在本例中为getItem()返回null。
