RecyclerView和ViewPager结合使用

你可以在ViewPager中放置一个包含多个RecyclerView的Fragment，这样就可以在ViewPager的每个页面中显示不同的RecyclerView。以下是一个简单的示例代码：

1. 创建一个包含RecyclerView的Fragment：

public class MyRecyclerViewFragment extends Fragment {      private RecyclerView recyclerView;     private RecyclerViewAdapter adapter;      public MyRecyclerViewFragment() {     }      @Override     public View onCreateView(LayoutInflater inflater, ViewGroup container,                              Bundle savedInstanceState) {         View view = inflater.inflate(R.layout.fragment_recycler_view, container, false);          recyclerView = view.findViewById(R.id.recyclerView);         recyclerView.setLayoutManager(new LinearLayoutManager(getContext()));                  adapter = new RecyclerViewAdapter();         recyclerView.setAdapter(adapter);          return view;     } } 

2. 创建一个包含ViewPager和多个MyRecyclerViewFragment的Activity：

public class MainActivity extends AppCompatActivity {      private ViewPager viewPager;     private PagerAdapter pagerAdapter;      @Override     protected void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.activity_main);          viewPager = findViewById(R.id.viewPager);         pagerAdapter = new MyPagerAdapter(getSupportFragmentManager());         viewPager.setAdapter(pagerAdapter);     }      private class MyPagerAdapter extends FragmentPagerAdapter {          public MyPagerAdapter(FragmentManager fm) {             super(fm);         }          @Override         public Fragment getItem(int position) {             return new MyRecyclerViewFragment();         }          @Override         public int getCount() {             return 3; // 3个页面         }     } } 

3. 创建RecyclerView的布局文件 fragment_recycler_view.xml：

<?xml version="1.0" encoding="utf-8"?> <androidx.recyclerview.widget.RecyclerView xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/recyclerView"     android:layout_width="match_parent"     android:layout_height="match_parent" /> 

4. 创建ViewPager的布局文件 activity_main.xml：

<?xml version="1.0" encoding="utf-8"?> <androidx.viewpager.widget.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/viewPager"     android:layout_width="match_parent"     android:layout_height="match_parent" /> 

通过以上代码，你可以在ViewPager的每个页面中显示不同的RecyclerView，从而实现RecyclerView和ViewPager的结合使用。
