java - 如何在单击按钮时更新回收器 View 中的 TextView ？

Question

每当我单击“喜欢”按钮时，我想为我的列表项创建一个“喜欢”按钮，然后 TextView 应该动态更新。但是当我单击该按钮时，只有最后一行会更新，其余行不会改变。请引导我完成在列表项中制作“like”按钮的任务。(我已经使用“likebutton”库来制作“like”按钮)。

RecyclerViewAdapter.java

public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder>{

private static final String TAG = "hh";
private String[] names;
private String[] desc;
private Integer[] imageid;
private Context context1;
ImageButton sare;
public ImageView img;
LikeButton likeButton;
TextView tx1;
TextView tx2;
TextView tx3;
TextView tx4;
public RecyclerViewAdapter(Context context2,String[] names,String[] desc,Integer[] imageid){
    this.names = names;
    this.desc = desc;
    this.imageid = imageid;
    context1 = context2;
}

public class ViewHolder extends RecyclerView.ViewHolder{

    public LikeButton likeButton;

    public ViewHolder(View v){

        super(v);


    }
}

@Override
public RecyclerViewAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType){

    View view1 = LayoutInflater.from(context1).inflate(R.layout.recycler_view_items,parent,false);

    ViewHolder viewHolder1 = new ViewHolder(view1);
    img = (ImageView) view1.findViewById(R.id.imgview1);
    likeButton = (LikeButton) view1.findViewById(R.id.cvcv);
    tx3 = (TextView)view1.findViewById(R.id.counttxt);
    likeButton.setOnLikeListener(new OnLikeListener() {
        @Override
        public void liked(LikeButton likeButton) {

            int count = Integer.parseInt(tx3.getText().toString());
            Log.d("fgfgfgfgf", String.valueOf(count));
            tx3.setText(String.valueOf(++count));
            //tx3.setText(String.valueOf(Homefragment.countt));
        }
        @Override
        public void unLiked(LikeButton likeButton) {

        }
    });
    return viewHolder1;
}

@Override
public void onBindViewHolder(ViewHolder Vholder,final int position){
    if(imageid[position] != null) {
       // img.setImageBitmap(imageid[position]);
    }
    else{
    }
    img.setImageResource(imageid[position]);
    tx1.setText(names[position]);

    Vholder.itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

        }
    });

}



@Override
public int getItemViewType(int position) {
    return position;
}

@Override
public int getItemCount(){

    return desc.length;
}

}

Answer 1

public class ViewHolder extends RecyclerView.ViewHolder{

    LikeButton likeButton;
    TextView tx1;
    TextView tx2;
    TextView tx3;
    TextView tx4;

    public ViewHolder(View v){
    super(v);
    img = (ImageView) v.findViewById(R.id.imgview1);
    likeButton = (LikeButton) v.findViewById(R.id.cvcv);
    tx3 = (TextView)v.findViewById(R.id.counttxt);



    }
}

将 OnCreateviewHolder 更改为:-

@Override
public RecyclerViewAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType){

    View view1 = LayoutInflater.from(context1).inflate(R.layout.recycler_view_items,parent,false);
    return new ViewHolder(view1);
}

OnBindViewHolder 到:-

@Override
public void onBindViewHolder(ViewHolder Vholder,final int position){
    Vholder.img.setImageResource(imageid[position]);
    Vholder.tx1.setText(names[position]);

    Vholder.itemView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

        }
    });
    Vholder.likeButton.setOnLikeListener(new OnLikeListener() {
    @Override
    public void liked(LikeButton likeButton) {

        //Logic
    }
    @Override
    public void unLiked(LikeButton likeButton) {

    }
    });
    }
