我有一个recyclerview，它在cardviews上加载复选框。这是适配器。加载时很好。但是，当我故意在recyclerview上检查某个项目时，会在某个随机位置选中一个复选框。我如何摆脱这个问题？这是我的适配器。提前致谢。
public class QuestionsAdapter extends RecyclerView.Adapter<QuestionsAdapter.QuestionsViewHolder> {
List<QuestionModel> Questions;
public Context context;
public QuestionsAdapter(Context context, List<QuestionModel> questions) {
this.Questions = questions;
this.context = context;
}
@Override
public QuestionsViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.questions_card_view, parent, false);
return new QuestionsViewHolder(v);
}
@Override
public void onBindViewHolder(QuestionsViewHolder holder, final int position) {
holder.txtQuestionText.setText(Questions.get(position).QuestionText);
}
@Override
public int getItemCount() {
return Questions.size();
}
@Override
public void onAttachedToRecyclerView(RecyclerView recyclerView) {
super.onAttachedToRecyclerView(recyclerView);
}
public class QuestionsViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
