Java 将值从Recyclerview传递到Fragment

我有一个“回收者”视图，它按行显示用户信息，每行都有 TextView显示名称，另一个TextView显示作业；我使用接口在recyclerview中处理OnitemClick以启动一个片段，它将显示用户数据名和作业，我尝试使用bundle将值从recyclerview适配器传递到片段，但bundle始终为null

这是我的适配器类

public class AuthorAdapter extends RecyclerView.Adapter<AuthorAdapter.MyViewHolder> {
private LayoutInflater inflater;
private Realm mRealm;
private RealmResults<AuthorInfo> results;
private LaunchFragment lanch;

public AuthorAdapter(Context context, RealmResults<AuthorInfo> realmResults, Realm realm, LaunchFragment mLaunch) {
    inflater = LayoutInflater.from(context);
    results = realmResults;
    mRealm=realm;
    lanch=mLaunch;
}


@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

    View view = inflater.inflate(R.layout.custom_row, parent, false);
    MyViewHolder holder = new MyViewHolder(view,lanch);
    return holder;
}

@Override
public void onBindViewHolder(MyViewHolder holder, final int position) {
    AuthorInfo current = results.get(position);


    holder.name.setText(current.getName());
    holder.job.setText(current.getJob());


}


@Override
public int getItemCount() {
    return results.size();
}




public class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
    TextView name;
    TextView job;
    ImageView image;
    CheckBox checkbox;

    ItemClickListener itemclicklistener;

    LaunchFragment launchFragment;

    public MyViewHolder(View itemView,LaunchCards listener) {
        super(itemView);

        name = (TextView) itemView.findViewById(R.id.tv_name);
        job = (TextView) itemView.findViewById(R.id.tv_job);
        image = (ImageView) itemView.findViewById(R.id.iv_author);
        checkbox = (CheckBox) itemView.findViewById(R.id.checkbox);
        checkbox.setOnClickListener(this);
        lanunchFragment=listener;
        image.setOnClickListener(this);

    }

    public void setClickListener(ItemClickListener ic) {
        this.itemclicklistener = ic;

    }


    @Override
    public void onClick(View view) {


        Fragment fragmentGet = new FragmentCard();
        Bundle bundle = new Bundle();
        bundle.putString("name",results.get(getAdapterPosition()).getName());
        fragmentGet.setArguments(bundle);

        lanunchFragment.onMark(getAdapterPosition());

    }
}

}

你知道为什么bundle总是空的吗？

你能分享lanunchFragment.onMark（getAdapterPosition（））的代码吗@这是launchfragment.onMark LaunchCards LaunchCards=new LaunchCards（）{@Override public void onMark（int位置）{showFragmetLaunch（）；}；这个showFragmentlaunch方法：private void showFragmetLaunch（）{FragmentCard FragmentCard fragment=new FragmentCard（）；FragmentManager maneger=getSupportFragmentManager（）；FragmentTransaction=maneger.beginTransaction（）；transaction.add（R.id.dump，fragment，“AuthorFrag”）；transaction.commit（）；}你能分享lanunchFragment.onMark（getAdapterPosition（））的代码吗@这是launchfragment.onMark LaunchCards LaunchCards=new LaunchCards（）{@Override public void onMark（int位置）{showFragmetLaunch（）；}；这个showFragmentlaunch方法：private void showFragmetLaunch（）{FragmentCard FragmentCard fragment=new FragmentCard（）；FragmentManager maneger=getSupportFragmentManager（）；FragmentTransaction=maneger.beginTransaction（）；transaction.add（R.id.dump，fragment，“AuthorFrag”）；transaction.commit（）；}
