android studio需求：使用public void onItemClickListener(View view, int position)方法对position进行判断，当position=0时，fragment跳转到fragment1，当position=1时，fragment跳转到fragment2

可以按照以下步骤实现你的需求：

1. 在你的项目中创建两个Fragment，分别为Fragment1和Fragment2。

2. 在你的RecyclerView的Adapter中实现onItemClickListener方法。代码如下：

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    private List<String> mData;
    private OnItemClickListener mClickListener;

    public interface OnItemClickListener {
        void onItemClick(View view, int position);
    }

    public void setOnItemClickListener(OnItemClickListener listener) {
        mClickListener = listener;
    }

    // ...其他代码

    public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
        TextView textView;

        ViewHolder(View itemView) {
            super(itemView);
            textView = itemView.findViewById(R.id.text_view);
            itemView.setOnClickListener(this);
        }

        @Override
        public void onClick(View v) {
            if (mClickListener != null) {
                mClickListener.onItemClick(v, getAdapterPosition());
            }
        }
    }
}

3. 在你的Activity或Fragment中获取RecyclerView的引用，设置Adapter和OnItemClickListener。代码如下：

public class MyFragment extends Fragment {
    private RecyclerView mRecyclerView;
    private MyAdapter mAdapter;

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_my, container, false);

        mRecyclerView = view.findViewById(R.id.recycler_view);
        mAdapter = new MyAdapter(getData());
        mRecyclerView.setAdapter(mAdapter);

        mAdapter.setOnItemClickListener(new MyAdapter.OnItemClickListener() {
            @Override
            public void onItemClick(View view, int position) {
                if (position == 0) {
                    // 跳转到Fragment1
                    FragmentManager fragmentManager = getFragmentManager();
                    FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
                    fragmentTransaction.replace(R.id.container, new Fragment1());
                    fragmentTransaction.addToBackStack(null);
                    fragmentTransaction.commit();
                } else if (position == 1) {
                    // 跳转到Fragment2
                    FragmentManager fragmentManager = getFragmentManager();
                    FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
                    fragmentTransaction.replace(R.id.container, new Fragment2());
                    fragmentTransaction.addToBackStack(null);
                    fragmentTransaction.commit();
                }
            }
        });

        return view;
    }

    // ...其他代码
}

这样，当点击RecyclerView中的第一个条目时，就会跳转到Fragment1；点击第二个条目时，就会跳转到Fragment2。
