我只是在测试这个,如果用户在显示时按下临时的“正在加载...”行,它将给出超出范围的异常。处理这个问题的最佳方法是什么?检查列表 OnItemCLickListener 上的 ID?

问候,

这是列表视图项侦听器:

实际ListView.setOnItemClickListener(新的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:

它在方法中的位置获取项目的行:

parent.getItemAtPosition(位置);

我在 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; 
                    }

从战术上讲,您需要自己过滤掉它,方法是检查position并查看您是否在最后一行。

我会寻找一个补丁EndlessAdapternull,在这种情况下会返回getItem().
