视图模型加载以前搜索的数据（通过改造调用），而不是新搜索的

Question

我对如何通过视图模型发送新查询以进行改造调用感到困惑。
我的活动如下：

    public class SearchActivity extends AppCompatActivity {
    RecyclerViewAdapter adapter;
    Button filter_button;
    RecyclerView recyclerView;
    EditText currentSearch;
    ImageButton imageButton;
    List<Hits> mHits = new ArrayList<>();
    String category;
    String order;
    String query;
    String editor_choice;
    String type;
    ViewModel model;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_search);
        filter_button = findViewById(R.id.button_filter);
        imageButton = findViewById(R.id.imageButton_search);
        currentSearch = findViewById(R.id.et_currentsearch);
        recyclerView = findViewById(R.id.recyclerview);


        // getSupportActionBar().setHomeAsUpIndicator(R.drawable.ic_arrow_back_black_24dp);

        final Intent intent = getIntent();
        category = intent.getStringExtra("category");
        order = intent.getStringExtra("order");
        query = intent.getStringExtra("searchQuery");
        editor_choice = intent.getStringExtra("editor");
        type = intent.getStringExtra("type");
        currentSearch.setText(query);

        recyclerView.setLayoutManager(new GridLayoutManager(this, 2));
        recyclerView.setHasFixedSize(true);
        adapter = new RecyclerViewAdapter(this, mHits);
        recyclerView.setAdapter(adapter);

        model = ViewModelProviders.of(this, new MyViewModelFactory(this.getApplication()
                , category, type, editor_choice, order, query)).get(ViewModel.class);
        model.getList().observe(this, new Observer<List<Hits>>() {
            @Override
            public void onChanged(List<Hits> hits) {
                adapter = new RecyclerViewAdapter(SearchActivity.this, hits);
                recyclerView.setAdapter(adapter);
            }
        });
        imageButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                newSearch();
            }
        });

        filter_button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent intent1 = new Intent(SearchActivity.this, MainActivity.class);
                intent1.putExtra("query", currentSearch.getText().toString().trim());
                startActivity(intent1);
            }
        });
    }

这是我正在使用的方法：

    void newSearch() {
        String newSearch = currentSearch.getText().toString();
        Log.d("___", "new Search : " + newSearch);
        ViewModel model1 = ViewModelProviders.of(this, new MyViewModelFactory(this.getApplication()
                , category, "photo", "false", "popular", newSearch)).get(ViewModel.class);
        model1.getList().observe(this, new Observer<List<Hits>>() {
            @Override
            public void onChanged(List<Hits> hits) {
                adapter = new RecyclerViewAdapter(SearchActivity.this, hits);
                recyclerView.setAdapter(adapter);
            }
        });


    }

}

“日志中的newSearch”显示所需的查询，但recyler视图仍显示先前获取的内容。

我的ViewModelFactory类：

public class MyViewModelFactory extends 
ViewModelProvider.AndroidViewModelFactory {


private Application context;
private String category;
private String image_type;
private String editor_choice;
private String orderBy;
private String query;
public MyViewModelFactory(@NonNull Application application,String category, String image_type,
                          String editor, String orderBy, String  query) {
    super(application);
    this.category = category;
    this.image_type = image_type;
    this.editor_choice = editor;
    this.orderBy = orderBy;
    this.query = query;
    this.context=application;
}

@NonNull
@Override
public <T extends ViewModel> T create(@NonNull Class<T> modelClass) {
    return (T) new com.example.picsearch.ViewModel(context,category,image_type
                        ,editor_choice,orderBy,query);
}

}

我是编程新手，请告诉我如何使用currentSearch文本作为新Retrofit调用的查询。
