单击 Item Inside recycler 视图时，如何在 viewpager2 中膨胀它们各自的片段？

问题描述

我有 MyViewPager2 适配器，其中包含四个 Fragment 和一个 SemesterFragment，其中包含 recyclerview DepartmentRVAdapter。在回收器视图中单击 onItem 我想移动到 viewpager2 中的相应片段

---

我怎样才能实现下面的描述？

• （onItem 点击0 pos）计算机科学系--->然后在viewpager2中加载片段（sem1,sem2,sem3,sem4）else if
• (onItem click on 1 pos) 统计部门--->然后在viewpager2中加载fragments(sem1,sem4)
• e.t.c

下面是我所拥有的，现在代码更专注了。谢谢

解决方法

每次点击相应的回收器视图项时，您是否都在问如何将数据膨胀到 ViewPagers 中的片段中？很抱歉，我没明白你的问题，我真的很想帮忙

,

这是我在我的一个项目中使用的 ViewPager 适配器：

public class PageAdapter extends FragmentPagerAdapter {
public ArrayList<Fragment> fragments = new ArrayList<>();
public ArrayList<String> name = new ArrayList<>();

public PageAdapter(@NonNull FragmentManager fm,int behavior) {
    super(fm,behavior);
}

public void AddFragment(Fragment fragment,String name){
    fragments.add(fragment);
    this.name.add(name);
}

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

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

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

}

如果你想给你的 ViewPager 添加一个片段，你只需使用以下代码：

private ViewPager viewPager;
private TabLayout tabLayout;

viewPager = findViewById(R.id.view_pager); //Your View Pager object
adapter = new PageEditorAdapter(getSupportFragmentManager(),0); //Initialize Adapter
viewPager.setAdapter(adapter); //Configuring with adapter

tabLayout = findViewById(R.id.tab_layout);
tabLayout.setupWithViewPager(viewPager); //Tab Layout,if you're using any

//You can execute the below code in the onClick block of your Recycler Adapter to perform fragment addition to view pager when clicked

adapter.AddFragment(new YourFragment(FragmentData),"View Pager Title"); //Adds new fragment to View Pager
adapter.notifyDataSetChanged(); //Notifies the adapter that changes has been done to the list of fragments
