如何在回收视图中获取确切位置

如何解决如何在回收视图中获取确切位置

我正在使用乐曲适配器，将我所有的按钮放在OnClickListener中。删除按钮可以使用，但是编辑按钮不起作用，因为它不知道歌曲的位置是需要编辑的

public class SongAdapter extends RecyclerView.Adapter<MyView> implements Filterable {
AlertDialog dialog;
EditText editText;
AlertDialog dialog2;
EditText editText2;

public SongAdapter(List<Song> songs)
{
    this.songs = songs;
    this.songsFiltered = songs;
}

public List <Song> songs;
public List <Song> songsFiltered;

Context context;
@NonNull
@Override
public MyView onCreateViewHolder(@NonNull ViewGroup parent,int viewType) {
    context = parent.getContext();
    LayoutInflater inflater = LayoutInflater.from(context);
    View songView = inflater.inflate(R.layout.item_song,parent,false);
    MyView viewHolder = new MyView(songView);
    return viewHolder;
}

@Override
public void onBindViewHolder(@NonNull MyView holder,final int position)
{
     Song song = songsFiltered.get(position);
     final TextView artist = holder.titleArtist;

     //edit
     artist.setText(song.getArtist());

     final TextView title = holder.titleTxt;

     //edit
     title.setText(song.getTitle());

     int imageId = AppUtil.getImageIdFromDrawable(context,song.getCoverArt());

     dialog = new AlertDialog.Builder(context).create();
     editText = new EditText(context);

     dialog.setTitle("Edit the Title");
     dialog.setView(editText);

     dialog2 = new AlertDialog.Builder(context).create();
     editText2 = new EditText(context);
     dialog2.setTitle("Edit the Artist");
     dialog2.setView(editText2);

     holder.image.setImageResource(imageId);
     holder.removeBtn.setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View view)
         {
             MainActivity.favList.remove(position);
             Gson gson = new Gson();
             String json = gson.toJson(MainActivity.favList);
             SharedPreferences.Editor editor = MainActivity.sharedPreferences.edit();
             editor.putString("list",json);
             editor.apply();
             notifyDataSetChanged();
         }
     });

问题出在这里。我不知道如何获得位置，以便我可以编辑确切的歌曲名称

     holder.editT.setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View view) {
                 editText.setText(title.getText());
                 dialog.show();
         }
     });

     dialog.setButton(DialogInterface.BUTTON_POSITIVE,"SAVE TEXT",new DialogInterface.OnClickListener() {
         @Override
         public void onClick(DialogInterface dialogInterface,int i) {
             title.setText(editText.getText());
         }
     });

    holder.editA.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            for(int i = 0; i < songs.size(); i++)
            {
                editText2.setText(artist.getText());
                dialog2.show();
            }
        }
    });
    dialog2.setButton(DialogInterface.BUTTON_POSITIVE,new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialogInterface,int i) {
            artist.setText(editText2.getText());
        }
    });



}

解决方法

尝试一下

在您的onBindViewHolder(...)

内部

holder.editT.setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View view) {
                 editText.setText(songsFiltered.get(position).getTitle());//here you will get current item which i assume is Song Object which have title as String
                 dialog.show();
         }
     });

     dialog.setButton(DialogInterface.BUTTON_POSITIVE,"SAVE TEXT",new DialogInterface.OnClickListener() {
         @Override
         public void onClick(DialogInterface dialogInterface,int i) {
             title.setText(editText.getText());
         }
     });
