RecycleView-Android/Java中的可自定义适配器存在问题

我正在用TextView、EditText和CheckBox实现一个可定制的适配器。我设法使所有项目都显示在我的RecycleView中，但是当选中复选框时，例如，下面某个项目的另一个复选框也被选中，编辑EditText时也会出现同样的情况，当更改某个项目的值时，列表中的另一个项目也会更改相同的值。我不知道如何避免这种情况，因为我执行了viewholder的看似正确的实现，请遵循实现下面的代码：

适配器实现代码：

public class Adapter_Lista_Bncc extends RecyclerView.Adapter {

private List<Pesquisa> lista;

private Context context;

public Adapter_Lista_Bncc(List<Pesquisa> lista, Context context){

    this.lista = lista;
    this.context = context;

}


@NonNull
@Override
public RecyclerView.ViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {

    View view = LayoutInflater.from(context).inflate(R.layout.adapter_lista_bncc, viewGroup, false);

    NossoViewHolder holder = new NossoViewHolder(view);


    return holder;
}

@Override
public void onBindViewHolder(@NonNull RecyclerView.ViewHolder viewHolder, int i) {

    NossoViewHolder holder = (NossoViewHolder) viewHolder;

    Pesquisa p = lista.get(i);

    holder.txt_bncc.setText(p.getVar1());
    holder.txt_descricao_bncc.setText(p.getVar2());
    holder.timer.setFilters(new InputFilter[]{new MinMaxFilter("1", "60")});

}

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

public class NossoViewHolder extends RecyclerView.ViewHolder{

    final TextView txt_bncc;
    final TextView txt_descricao_bncc;
    final EditText timer;
    final CheckBox check;

    public NossoViewHolder(View v){
        super(v);

        txt_bncc = (TextView) v.findViewById(R.id.txt_bncc);
        txt_descricao_bncc = (TextView) v.findViewById(R.id.txt_descricao_bncc);
        timer = (EditText) v.findViewById(R.id.timer);
        check = (CheckBox) v.findViewById(R.id.checkbox_bncc);

    }

}
}

我可以提供更多有关情况的信息，我感谢您的关注和任何能够提供帮助的人。

好的，首先为了获得更好的性能，请迁移到Androidx并在单击列表器上实现，在适配器上，您应该实现接口以传递您的位置，以便您可以在活动中访问并更改它们。我将更正您的适配器，如下面的复选框所示只检查其他人

public class Adapter_Lista_Bncc extends RecyclerView.Adapter {

private List<Pesquisa> lista;

private Context context;
// here is our interface 
private OnItemClickListner listner;

public Adapter_Lista_Bncc(List<Pesquisa> lista, Context context){

    this.lista = lista;
    this.context = context;

}


@NonNull
@Override
public RecyclerView.ViewHolder onCreateViewHolder(@NonNull ViewGroup viewGroup, int i) {

    View view = LayoutInflater.from(context).inflate(R.layout.adapter_lista_bncc, viewGroup, false);

    NossoViewHolder holder = new NossoViewHolder(view);


    return holder;
}

@Override
public void onBindViewHolder(@NonNull RecyclerView.ViewHolder viewHolder, int i) {

    NossoViewHolder holder = (NossoViewHolder) viewHolder;

    Pesquisa p = lista.get(i);

    holder.txt_bncc.setText(p.getVar1());
    holder.txt_descricao_bncc.setText(p.getVar2());
    holder.timer.setFilters(new InputFilter[]{new MinMaxFilter("1", "60")});

}

@Override
public int getItemCount() {
    return lista.size();
}
// implemet on click listner
