Java 调用LiveData onChanged（）方法时，ListAdapter项呈现不正确。DiffUtil可能存在的问题是内容相同（）？

我目前正在创建一个Android应用程序，帮助您完成任务。我使用LiveData和ListAdapter，它在一个片段中列出所有不同的任务，并使用DiffUtil测试ListAdapter中的更改。在我解释我的问题之前：以下是一些相关代码：

SubTaskFragment.java：

public class SubTaskFragment extends Fragment {
private RecyclerView recyclerView;

private SubTaskAdapter adapter;
private SubTaskViewModel viewModel;

private static final String TAG = "SubTaskFragment";

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment and setup recycler view
    View rootView = inflater.inflate(R.layout.fragment_sub_task, container, false);
    recyclerView = (RecyclerView) rootView.findViewById(R.id.sub_task_recycler_view);
    recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));

    //set adapter
    adapter = new SubTaskAdapter(getContext());
    recyclerView.setAdapter(adapter);

    viewModel = ViewModelProviders.of(this).get(SubTaskViewModel.class);
    viewModel.getSubTasks().observe(getViewLifecycleOwner(), new Observer<List<SubTask>>() {
        @Override
        public void onChanged(@Nullable List<SubTask> subTasks) {
            //Update RecyclerView
            Log.d(TAG, "onChanged: subTasks length = " + subTasks.size());
            adapter.submitList(subTasks);
        }
    });

我遇到的下一个可能是相关的问题是，每当列表项“过期”（红色的任务）时，ListAdapter中的其他项。这不是它应该发挥作用的方式。这些列表项应该是白色的，因为这些任务没有过期。当我再次选中/取消选中它时，它最终会再次变回白色

检查过期任务时，应用程序功能正常。它将从屏幕上删除，因为我的SQL SELECT语句不再返回已检查的过期任务

这是我两次选中/取消选中未过期列表项时的日志（第3个gif）。这里需要注意的一点是，当选中测试1时，

AreContentsSame（）

在选中列表项时正确返回false，因为isCompleted已从true设置为false。但是，

areContentsTheSame（）

在取消选中时不正确地返回true，即使isCompleted已从true设置为false。此外，即使isOverdue为false，列表项也会突然变为红色：

我注意到的另一件事是，对列表中的每个项目调用两次

areItemsTheSame（）

，而对每个列表项目只调用一次

areContentsTheSame（）

。这似乎不是正常的行为，所以这可能是造成问题的原因之一。关于这两个问题是否相关以及如何解决它们，您有什么想法吗？

这里有两个问题。第一个（灰色突出显示）是由于RecyclerView的内置默认动画而发生的。选中该框后，RecyclerView将创建一个新的

视图保持架

，并进行交叉淡入淡出。有关如何解决此问题的更多信息，请参见此问题/答案：

第二个（红色背景）是

onBindViewHolder（）

方法中的一个错误，该错误阻止视图正确回收：

---

像这样的每个

if

语句都需要一个

else

案例来将视图设置回正常颜色。如果没有这样的

else

，您的红色视图将被循环到另一个位置，并且不会改变颜色。

谢谢！我能够解决关于红色背景的第二个问题，但是我有一些关于交叉褪色的问题。您提供的示例使用了notifyItemChange（）。如果我不使用任何notify方法，并且仅依赖DiffUtil来检测我的ListAdapter中的任何差异，我如何能够防止这种交叉褪色？DiffUtil有一个

getChangePayload（）

方法，您可以使用该方法以我的第一个链接显示的方式提供有效负载。查看此问题/答案了解详细信息：如果不起作用，请告诉我。我假设带有第二个参数的

getChangePayload（）

和

notifyItemChanged（）

的功能基本相同。更新：我从布尔表达式中删除了

oldTask.isCompleted（）==newTask.isCompleted（）

，它停止了交叉淡入。唯一的问题是，此实现将导致具有相同名称、截止日期和主任务id的两个任务评估为true，即使其中一个任务已完成，而另一个任务未完成。这在使用应用程序时很少发生，但可能有更好的实现。感谢您的帮助。当

oldTask.isCompleted（）时，我通过使
getchangefailable（）返回
Boolean.FALSE
修复了这个问题newTask.isCompleted（）
