android - 将值从适配器传递到 fragment 类时出现问题？

Question

我正在将值从适配器传递到 fragment 类，

这里是适配器类，

 rbFolder.setOnClickListener(new View.OnClickListener()
        {
            @Override
            public void onClick(View v)
            {
                if(selected != null)
                {
                    selected.setChecked(false);
                    String meee =  data.get(position).getTypeId();
                    System.out.println("*******so*inside********"+meee);

                }

                rbFolder.setChecked(true);
               String so =  data.get(position).getTypeId();
                System.out.println("*******so*********"+so);
                selected = rbFolder;
                System.out.println("********selected*******"+selected);
                Fragment homepage = new Fragment();
                FragmentTransaction fragmentManager =((FragmentActivity)context).getSupportFragmentManager()
                        .beginTransaction();
                Bundle bundle=new Bundle();
                bundle.putString("name", so); //key and value
                System.out.println("*****venki***meee*******"+so);

                homepage.setArguments(bundle);
              //  fragmentManager.replace(R.id.content_frame, homepage);
                fragmentManager.addToBackStack(null);
                fragmentManager.commit();
            }
        });

在此，putstring 运行良好，但在我的 fragemt 类中我没有收到值。我在这个地方有麻烦。这里是 Fragmnet 类，

      public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    if (rootview != null) {
        ViewGroup parent = (ViewGroup) rootview.getParent();
        if (parent != null)
            parent.removeView(rootview);
    }
    try {

        rootview = inflater.inflate(R.layout.homepage, container, false);
    } catch (InflateException e) {
    /* map is already there, just return view as it is */
    }

这里我从适配器获取值，但这不起作用，

   Bundle bundle = ((Activity)context).getIntent().getExtras();
    if (bundle != null)
    {
        String strtext=getArguments().getString("name");
        System.out.println("*******strtext*********"+strtext);

    }

    return rootview;
}

首先你必须调用你的HomeFragment() 而不是那样的fragment

Fragment homepage = new HomeFragment();
            FragmentTransaction fragmentManager =((FragmentActivity)context).getSupportFragmentManager()
                    .beginTransaction();
            Bundle bundle=new Bundle();
            bundle.putString("name", so); //key and value
            homepage.setArguments(bundle);
            fragmentManager.replace(R.id.content_frame, homepage);
            fragmentManager.addToBackStack(null);
            fragmentManager.commit();

当你想在 home fragment 中获取值时

    if( getArguments() != null)
      String strtext = getArguments().getString("name");
