Java 罢工通过文本标志未按预期工作

这是我的RecyclerView适配器类

public class TodoAdaptor extends RecyclerView.Adapter<TodoAdaptor.SingleTodoView> {

    private CheckBox checkbox;
    private TextView title, dueDate;
    private Context context;
    private ArrayList<SingleTodo> todoList;
    private onItemCLickListener itemCLickListener;

    public TodoAdaptor(Context context, ArrayList<SingleTodo> todoList, onItemCLickListener onItemClickListener) {
        this.context = context;
        this.todoList = todoList;
        this.itemCLickListener = onItemClickListener;
    }


    @NonNull
    @Override
    public SingleTodoView onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.single_todo, parent, false);
        return new SingleTodoView(v, itemCLickListener);
    }

    @Override
    public void onBindViewHolder(@NonNull SingleTodoView holder, int position) {
        SingleTodo singleTodo = todoList.get(position);
        checkbox.setChecked(singleTodo.isComplete());
        title.setText(singleTodo.getTitle());
         if (singleTodo.isComplete()) {
            title.setPaintFlags(title.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);
            Toast.makeText(context, "IsCompleted", Toast.LENGTH_SHORT).show();
        } else {
            title.setPaintFlags(title.getPaintFlags() & (~Paint.STRIKE_THRU_TEXT_FLAG));
            Toast.makeText(context, "Not IsCompleted", Toast.LENGTH_SHORT).show();
        }
        if (singleTodo.getDueDate().isEmpty()) {
            dueDate.setVisibility(View.GONE);
        } else {
            dueDate.setText(singleTodo.getDueDate());
        }
    }

    @Override
    public int getItemCount() {
        return todoList.size();
    }

    class SingleTodoView extends RecyclerView.ViewHolder {

        private SingleTodoView(@NonNull View itemView, final onItemCLickListener itemCLickListener) {
            super(itemView);
            checkbox = itemView.findViewById(R.id.todo_list_completed_checkbox);
            title = itemView.findViewById(R.id.todo_list_title);
            dueDate = itemView.findViewById(R.id.todo_list_due_date);
            title.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    itemCLickListener.onTextClickListener(getAdapterPosition());
                }
            });
            checkbox.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    itemCLickListener.onCheckboxClickListener(getAdapterPosition());
                }
            });
        }
    }

    public interface onItemCLickListener {
        void onTextClickListener(int position);
        void onCheckboxClickListener(int position);
    }
}

这是我的单打课

package com.example.simpletodo.classes;

public class SingleTodo {
    private int id;
    private String title;
    private String dueDate;
    private boolean isComplete;

    public SingleTodo(int id, String title, String dueDate, boolean isComplete) {
        this.id = id;
        this.title = title;
        this.dueDate = dueDate;
        this.isComplete = isComplete;
    }

    public int getId() {
        return id;
    }

    public String getTitle() {
        return title;
    }

    public String getDueDate() {
        return dueDate;
    }

    public boolean isComplete() {
        return isComplete;
    }

    public void setId(int id) {
        this.id = id;
    }

    public void setTitle(String title) {
        this.title = title;
    }

    public void setDueDate(String dueDate) {
        this.dueDate = dueDate;
    }

    public void setComplete(boolean complete) {
        isComplete = complete;
    }
}

每当我选中该复选框时，该项的文本都应该画出删除线，并且它没有按预期工作

我在列表中有3个项目，当我单击复选框时，项目被选中，文本删除线起作用，但当我再次单击复选框时，复选框保持选中状态（尽管对象正在按应有的方式更新），删除线文本恢复为正常，我必须再次单击复选框两次，复选框才能被取消选中

另一个问题是，当我检查项目，然后我尝试检查其他项目时，当前项目文本将被另一个检查项目文本替换。 图像：
默认值：

单击复选框一次：

再次单击复选框时：

当我一个接一个地检查多个项目时（在检查项目是否处于默认顺序之前和检查之后，我没有更改任何项目的位置--按顺序--这就是我得到的）

感谢您的帮助。我只想让我的代码按预期工作。

我从问题中找到了解决方案

我不得不改变我的适配器类。我在ViewHolder类和onBindViewHolder中声明了视图，我使用第一个参数（holder）来获取我的视图

public class TodoAdaptor extends RecyclerView.Adapter<TodoAdaptor.SingleTodoView> {
    private boolean darkTheme;
    private Context context;
    private ArrayList<SingleTodo> todoList;
    private onItemCLickListener itemCLickListener;

    public TodoAdaptor(Context context, ArrayList<SingleTodo> todoList, boolean darkTheme, onItemCLickListener onItemClickListener) {
        this.darkTheme = darkTheme;
        this.context = context;
        this.todoList = todoList;
        this.itemCLickListener = onItemClickListener;
    }


    @NonNull
    @Override
    public SingleTodoView onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View v = LayoutInflater.from(context).inflate(R.layout.single_todo, parent, false);
        return new SingleTodoView(v, itemCLickListener);
    }

    @Override
    public void onBindViewHolder(@NonNull SingleTodoView holder, int position) {
        SingleTodo singleTodo = todoList.get(position);
        holder.checkbox.setChecked(singleTodo.isComplete());
        holder.title.setText(singleTodo.getTitle());
        if (singleTodo.isComplete()) {
            holder.title.setPaintFlags(holder.title.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);
        } else {
            holder.title.setPaintFlags(holder.title.getPaintFlags() & (~Paint.STRIKE_THRU_TEXT_FLAG));
        }
        if (singleTodo.getDueDate().isEmpty()) {
            holder.dueDate.setVisibility(View.GONE);
        } else {
            holder.dueDate.setVisibility(View.VISIBLE);
            holder.dueDate.setText(singleTodo.getDueDate());
        }
    }

    @Override
    public int getItemCount() {
        return todoList.size();
    }

    class SingleTodoView extends RecyclerView.ViewHolder {

        private CheckBox checkbox;
        private TextView title, dueDate;
        private SingleTodoView(@NonNull View itemView, final onItemCLickListener itemCLickListener) {
            super(itemView);
            checkbox = itemView.findViewById(R.id.todo_list_completed_checkbox);
            title = itemView.findViewById(R.id.todo_list_title);
            dueDate = itemView.findViewById(R.id.todo_list_due_date);
            if (darkTheme) {
                title.setTextColor(context.getResources().getColor(R.color.colorLightGray));
                dueDate.setTextColor(context.getResources().getColor(R.color.colorLightGray));
            } else {
                title.setTextColor(context.getResources().getColor(R.color.colorBlack));
                dueDate.setTextColor(context.getResources().getColor(R.color.colorBlack));
            }

            title.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    itemCLickListener.onTextClickListener(getAdapterPosition());
                }
            });
            checkbox.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    itemCLickListener.onCheckboxClickListener(getAdapterPosition());
                }
            });
        }
    }

    public interface onItemCLickListener {
        void onTextClickListener(int position);

        void onCheckboxClickListener(int position);
    }
}
