導(dǎo)入以下依賴??

implementation 'q.rorbin:VerticalTabLayout:1.2.5'

XML的布局使用

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.douwenxuan.view.category.CategoryFragment">
 
<q.rorbin.verticaltablayout.VerticalTabLayout
    android:id="@+id/vTab"
    android:layout_alignParentLeft="true"
    android:layout_width="80dp"
    android:layout_height="match_parent"
    android:background="@color/white"/>
<android.support.v4.view.ViewPager
    android:id="@+id/vp_sort"
    android:layout_toRightOf="@id/vTab"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>
 
</RelativeLayout>

JAVA中的書寫

public class CategoryFragment extends BaseFragment implements CategoryContract.View {
 
    @BindView(R.id.vTab)
    VerticalTabLayout vTab;
    @BindView(R.id.vp_sort)
    ViewPager vpSort;
    Unbinder unbinder;
 
 
    @Override
    protected int getLayout() {
        return R.layout.fragment_category;
    }
 
    @Override
    protected void initView(View view) {
 
    }
 
    @Override
    protected void initData() {
        ((CategoryPresenter)presenter).category();
    }
 
    @Override
    protected IPresenter createPresenter() {
        return new CategoryPresenter();
    }
 
    @Override
    public void showErrMsg(String err) {
        Toast.makeText(getActivity(), err, Toast.LENGTH_SHORT).show();
    }
 
    @Override
    public void categoryDataReturn(List<CategoryListBean> categoryList) {
        final ArrayList<String> tabName = new ArrayList<>();
        final ArrayList<Fragment> fragments = new ArrayList<>();
 
        for (int i = 0; i < categoryList.size(); i++) {
            fragments.add(new CategoryTabFragment(categoryList.get(i).getName(), categoryList.get(i).getId() + ""));
            tabName.add(categoryList.get(i).getName());
        }
        FragTabAdapter fragTabAdapter = new FragTabAdapter(getChildFragmentManager(), fragments,
                tabName);
        vpSort.setAdapter(fragTabAdapter);
        vTab.setupWithViewPager(vpSort);
    }
 
}

FragTabAdapter的書寫入下

public class FragTabAdapter extends FragmentPagerAdapter {
   private ArrayList<Fragment> fragments = new ArrayList<>();
   private ArrayList<String> tabName = new ArrayList<>();

   public FragTabAdapter(FragmentManager fm, ArrayList<Fragment> fragments, ArrayList<String>
           tabName) {
       super(fm);
       this.fragments = fragments;
       this.tabName = tabName;
   }

   @Override
   public Fragment getItem(int i) {
       return fragments.get(i);
   }

   @Override
   public int getCount() {
       return fragments.size();
   }

   @Nullable
   @Override
   public CharSequence getPageTitle(int position) {
       return tabName.get(position);
   }
}
