如何从适配器recycleview向另一个活动传递/获取值复选框

public class MyViewHolder extends RecyclerView.ViewHolder {
    CheckBox checkBox;

    public MyViewHolder(View itemView) {
        super(itemView);
        checkBox = itemView.findViewById(R.id.checkbox);

        checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                // 在这里处理复选框状态变化的逻辑
            }
        });
    }
}

private HashMap<Integer, Boolean> checkedItems = new HashMap<>();

// 在适配器的onBindViewHolder方法中设置复选框的状态
@Override
public void onBindViewHolder(MyViewHolder holder, int position) {
    // 设置复选框状态
    holder.checkBox.setChecked(checkedItems.get(position));

    // 其他绑定数据的操作
}

checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
    @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        int position = getAdapterPosition();
        checkedItems.put(position, isChecked);
    }
});

public List<DataItem> getSelectedItems() {
    List<DataItem> selectedItems = new ArrayList<>();
    for (Map.Entry<Integer, Boolean> entry : checkedItems.entrySet()) {
        if (entry.getValue()) {
            selectedItems.add(dataList.get(entry.getKey()));
        }
    }
    return selectedItems;
}

MyAdapter adapter = new MyAdapter(dataList);
recyclerView.setAdapter(adapter);

// 在需要的时候获取选中的数据项
List<DataItem> selectedItems = adapter.getSelectedItems();
