我正在创建一个视频播放器，它有一个重命名视频功能，几乎我已经做了重命名功能的工作，但它不能正常工作。
1.重命名文件，但不更新视频列表和回收程序视图。

使用此适配器，单击它更新视频和recyclerview中的名称，但没有在正确的位置更新，即使我使用位置变量，但它仍然没有正确更新。
示例：如果我想更新列表中的第三个视频，则会更新第二个视频;如果我想更新最后一个视频，则会正确更新。

adapter.setOnItemClickListner(new video_adepter.onItemClickListner() {
            @Override
            public void onClick(int position, String new_name) {
                Toast.makeText(getContext(), "update text " + video_list.get(position).getTxt_video_name(), Toast.LENGTH_SHORT).show();
                video_list.get(position).setTxt_video_name(new_name);
                adapter.notifyDataSetChanged();

            }
        });

我已经张贴了下面的所有代码。

视频适配器.java

case R.id.action_add_rename:

                    f_file = new File(Path);
                    final File from = new File(Path);

                    Fragment currentFragment = ((AppCompatActivity) mContext).getSupportFragmentManager().findFragmentById(R.id.fragment_container);
                    if (currentFragment instanceof folder_video_list) {
                        folder_video_list = currentFragment;

                    }

                    });
                    alertDialog.create().show();

文件夹_视频_列表.java（片段）

RecyclerView.LayoutManager mLayoutManager = new GridLayoutManager(getActivity(), 1);
        recyclerView.setLayoutManager(mLayoutManager);
        recyclerView.setItemAnimator(new DefaultItemAnimator());
        recyclerView.setAdapter(adapter);

        adapter.setOnItemClickListner(new video_adepter.onItemClickListner() {
            @Override
            public void onClick(int position, String new_name) {
                Toast.makeText(getContext(), "update text " + video_list.get(position).getTxt_video_name(), Toast.LENGTH_SHORT).show();
                video_list.get(position).setTxt_video_name(new_name);
                adapter.notifyDataSetChanged();

            }
        });

请帮我重命名一个视频，并立即更新其名称上recyclerview。
