相同的数据出现在整个Recyclerview中，并且位置增加，但是数据相同。
在useradapter中，我记录了位置和位置增加，但是onbindviewholder中的数据相同
useradapter
public class useradapter extends RecyclerView.Adapter<useradapter.CustomView> {
String nn = "m";
List<allusermodel> list1;
private Context context;
private LayoutInflater layoutInflater;
public useradapter(Context context, List<allusermodel> list1) {
Log.e("reached1", nn);
this.context = context;
this.list1 = list1;
}
@Override
public useradapter.CustomView onCreateViewHolder(final ViewGroup parent, final int viewType) {
Log.e("reached2", nn);
if (layoutInflater == null) {
layoutInflater = LayoutInflater.from(parent.getContext());
}
final Entrys newsBinding = Entrys.inflate(layoutInflater, parent, false);
// View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.innerlayout,parent,false);
return new CustomView(newsBinding);
}
@Override
public void onBindViewHolder(useradapter.CustomView holder,int position) {
Log.e("reached3", nn);
// News news = newsList.get(position);
// holder.desc.setText(news.getDesc());
allusermodel newsModel1 = list1.get(position);
// Log.e("list", String.valueOf(list1));
Log.e("nameeeee",newsModel1.getAll_user());
// Log.e("position", String.valueOf(position));
//Log.e("names",newsModel1.getAll_user());
holder.bind(newsModel1);
}
@Override
public int getItemCount() {
return list1.size();
}
public class CustomView extends RecyclerView.ViewHolder {
private Entrys newsBinding;
// public TextView title;
//TextView title, desc;
public CustomView(Entrys newsBinding) {
super(newsBinding.getRoot());
this.newsBinding = newsBinding;
Log.e("reached4", nn);
// title = (TextView)itemView.findViewById(R.id.titleval);
//desc =(TextView)itemView.findViewById(R.id.descval);
newsBinding.setRecyclerclick(new Presenters2() {
@Override
public void onclickListener() {
int pos = getAdapterPosition();
if (pos != RecyclerView.NO_POSITION) {
allusermodel clickedDataItem = list1.get(pos);
Intent intent = new Intent(context, messagelist.class);
intent.putExtra("clickid", clickedDataItem.getId());
context.startActivity(intent);
}
}
});
}
public void bind(allusermodel newsModel1)
{
Log.e("reached5", String.valueOf(newsModel1));
//String j = newsModel1.getAll_user();
// Log.e("bind",nn);
this.newsBinding.setAlluserentry(newsModel1);
}
public Entrys getNewsBinding() {
Log.e("reached6", nn);
return newsBinding;
}
}
}

整个recyclerview具有我之前在api中添加的相同数据 （如果我在条目中输入名称，那么它将在整个recylerview中显示上一个条目 ane然后如果我在输入中输入name1，那么它将在整个recylerview中显示名称）
答案 0 :(得分：0)
似乎出现了问题，因为当您从服务器填充数据时，您已经在for循环之外创建了Model对象。结果，列表中的最后一个值将显示给所有RecyclerView项目。
现在的解决方案是，在“ for-loop”中创建模型作为第一条语句。
public void getdata() {
dataManger.sendVolleyRequest1(token2, userlist.this, new DataValue() {
@Override
public void setJsonDataResponse1(JSONArray response) {
//allusermodel userModel = new allusermodel();
// newsList = new ArrayList<>();
for (int i = 0; i < response.length(); i++) {
allusermodel userModel = new allusermodel();
try {
JSONObject jsonObject = response.getJSONObject(i);
我希望它能解决您的问题。
