如何从回收视图中保存所选项目的 state？

Question

我的chatListLinearLayout 中有多个项目，我想更新我的messageStatus 来为所选项目说出诸如“已选择项目”之类的内容。 我成功地做到了这一点，但我想保存它，以便下次用户重新打开应用程序时它会保留。有人可以帮助我吗？

displayMessagesRecycleView.addOnItemTouchListener(new RecyclerItemClickListener(getContext(), new RecyclerItemClickListener.OnItemClickListener() {
                    @Override
                    public void onItemClick(View view, final int position) {
                        CircleImageView profileImage = view.findViewById(R.id.users_profile_image);
                        LinearLayout chatListLinearLayout = view.findViewById(R.id.chatListLinearLayout);
                        final TextView messageStatus = view.findViewById(R.id.user_status);


                        chatListLinearLayout.setOnClickListener(new View.OnClickListener() {
                            @Override
                            public void onClick(View v) {
                                messageStatus.setText("Item selected");



                            }
                        });

你可以setSelected(true); for view and set one boolean in you object model and for save selected item state you need to save your list into sharedPrefs or sqlite database
