想从列表视图中删除项目并添加到另一个列表视图

Question

它正在从列表中删除但根据位置添加。因此在列表中添加重复项目列表。

refreshedList.remove(new_position); 
mg_mappingAdapter2.notifyDataSetChanged(); 
mgBenData.add(mgBenData.get(new_position)); 
mg_mappingAdapter.notifyDataSetChanged(); 
mg_mappingAdapter2 = new MgMappingAdapter2(getActivity(), refreshedList); 
mg_mappingAdapter = new MgMappingAdapter11(getActivity(), 
    R.layout.mgnregauserlistlayout,mgBenData); 
mListView.setAdapter(mg_mappingAdapter); 
mappedListView.setAdapter(mg_mappingAdapter2); 

Answer 1

试试这个方法：

Object object = refreshedList.remove(new_position); // replace Object with Element type of List, ArrayList<Element> 
mgBenData.add(object); 
mg_mappingAdapter2.notifyDataSetChanged(); 
mg_mappingAdapter.notifyDataSetChanged(); 
mg_mappingAdapter2 = new MgMappingAdapter2(getActivity(), refreshedList); 
mg_mappingAdapter = new MgMappingAdapter11(getActivity(), 
R.layout.mgnregauserlistlayout,mgBenData); 
    mListView.setAdapter(mg_mappingAdapter); 
    mappedListView.setAdapter(mg_mappingAdapter2); 

其中显示一个list.Hope它会帮你删除的项目列表，只需添加删除的项目。
