Android刷新适配器工作后再次旋转设备

当我将一些数据添加到“列表模型”中并且在旋转设备上恢复保存的数据时,此代码工作正常,不幸的是,在恢复数据并将其设置为在OnRestoreInstanceState方法之后建模,在添加其他数据后,适配器无法使用新添加的数据刷新,适配器中的数据源可以更新,但适配器可以;不知道他们,我使用MVVM数据模型绑定和搜索更多的时间关于这个问题我无法解决.

Rhat有一个简单的提示,再次旋转设备后,我的适配器可以刷新所有添加的数据,哪个适配器不刷新它们.

public class ActivityRegister extends BaseActivities{
    private  List<Robotviewmodel> model  = new ArrayList<>();
    ...
    @Override
    public void onCreate(@Nullable Bundle savedInstanceStatE) {
        super.onCreate(savedInstanceStatE);

        ...
    }

    @Override
    protected void onSaveInstanceState(Bundle outStatE) {
        outState.putParcelable("model",Parcels.wrap(model));
        super.onSaveInstanceState(outStatE);
    }

    @Override
    protected void onRestoreInstanceState(Bundle outStatE) {
        model = ParcelS.Unwrap(outState.getParcelable("model"));

        adapter.setData(model);
        adapter.notifyItemInserted(model.size() - 1);
        binding.registerRobot.scrollToPosition(adapter.getItemCount() - 1);
    }@H_404_5@ 
 
添加到模型方法：
 
  
 
@Override
    public void clickOnSendCommandToRobot() {
        Robotviewmodel temp = new Robotviewmodel();

temp.setmessage("message");

        temp.setCommand(true);

        model.add(temp);

        adapter.notifyItemInserted(model.size() - 1);
        binding.registerRobot.scrollToPosition(adapter.getItemCount() - 1);
    }@H_404_5@ 
 
我的适配器类：
 
  
 
public class RobotmessagesAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {
    private List<Robotviewmodel> list;
    private LayoutInflater       inflater;

    public RobotmessagesAdapter(List<Robotviewmodel> robotviewmodels) {
        this.list = robotviewmodels;
    }

    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent,int viewTypE) {
        if (inflater == null) {
            inflater = LayoutInflater.from(parent.getContext());
        }
        if (viewType == SV.RobotmessageType.SENT_BY_USER.ordinal()) {
            return new U@R_489_9260@ewHolder(UsermessagesDataBinding.inflate(inflater,parent,falsE));
        } else {
            return new RobotViewHolder(RobotDataBinding.inflate(inflater,falsE));
        }
    }

    @Override
    public void onBindViewHolder(RecyclerView.ViewHolder holder,int position) {
        switch (getItemViewType(position)) {
            case 0:
                ((U@R_489_9260@ewHolder) holder).bind(list.get(position));
                break;
            case 1:
                ((RobotViewHolder) holder).bind(list.get(position));
                break;
        }
    }

    ...

    public void setData(List<Robotviewmodel> data) {
        Log.e("data size ",data.size() + "");
        list.clear();
        list.addAll(data);
    }
}@H_404_5@ 
 
我想知道为什么这段代码工作正常：
 
  
 
@Override
    protected void onRestoreInstanceState(Bundle outStatE) {
        model = ParcelS.Unwrap(outState.getParcelable("model"));

        adapter.setData(model);
        adapter.notifyItemInserted(model.size() - 1);
        binding.registerRobot.scrollToPosition(adapter.getItemCount() - 1);

        Robotviewmodel temp = new Robotviewmodel();

temp.setmessage("message");

        temp.setCommand(true);

        model.add(temp);

        adapter.notifyItemInserted(model.size() - 1);
        binding.registerRobot.scrollToPosition(adapter.getItemCount() - 1);
    }@H_404_5@ 
 
没有任何问题,后移动这行：
 
  
 
Robotviewmodel temp = new Robotviewmodel();

temp.setmessage("message");

        temp.setCommand(true);

        model.add(temp);

        adapter.notifyItemInserted(model.size() - 1);
        binding.registerRobot.scrollToPosition(adapter.getItemCount() - 1);@H_404_5@ 
 
到其他不起作用的方法：|
 
 
我的主持人：
 
  
 
public class ActivityRegisterPresenter {
    private ActivityRegisterContract view;

    public ActivityRegisterPresenter(ActivityRegisterContract mView) {
        view = mView;
    }

    ...
}@H_404_5@ 
 
和我的viewmodel：
 
  
 
public class ActivityRegisterviewmodel extends BaSEObservable {
    private String ReadContactPermission;
    private String getmessages;

    public ActivityRegisterviewmodel() {
    }

    @Bindable
    public String getReadContactPermission() {
        return ReadContactPermission;
    }

    public void setReadContactPermission(String ReadContactPermission) {
        this.ReadContactPermission = ReadContactPermission;
        notifyChange();
    }

    public String getGetmessages() {
        return getmessages;
    }

    public void setGetmessages(String getmessages) {
        this.getmessages = getmessages;
    }
}@H_404_5@

问题在clickOnRegisterMobilenumber和clickOnSendCommandToRobot方法

android:configChanges="screenSize|orientation|screenLayout"@H_404_5@ 
 
但是,如果您仅在这两种模式下设计“纵向”和“横向”布局或运行应用程序,则会返回最佳视图.
