java - 使用 ViewPager 将 RecyclerView 添加到 Tabs fragment

Question

我有一个带有 2 个选项卡的简单 fragment ，我想在每个 fragment 中添加一个 recyclerview。我的问题是如何将 recyclerview 附加到每个 fragment ？这是我的主适配器

public class MainActivity extends AppCompatActivity {
  private List<ListMenu> menuList = new ArrayList<>();
  private RecyclerView recyclerView;
  private MenuAdapter mAdapter;
  @Override        
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    TabLayout tabLayout = (TabLayout) findViewById(R.id.tab_layout);
    tabLayout.addTab(tabLayout.newTab().setText("SINGLE"));
    tabLayout.addTab(tabLayout.newTab().setText("PACKET"));
    tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);

    final ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
    final Pageradapter adapter = new Pageradapter(
                     getSupportFragmentManager(), tabLayout.getTabCount());
    viewPager.setAdapter(adapter);
    viewPager.addOnPageChangeListener(
                    new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
    tabLayout.setOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
      @Override
      public void onTabSelected(TabLayout.Tab tab) {
        viewPager.setCurrentItem(tab.getPosition());
      }        
      @Override
      public void onTabUnselected(TabLayout.Tab tab) {}
      @Override
      public void onTabReselected(TabLayout.Tab tab) {}
      });
  }
}

您必须将 FragmentPagerAdapter 或 PagerAdapter 与 Fragment 一起使用

你可以看到例子:
