我想创建具有自定义适配器的弹出列表的搜索视图。我有可筛选的界面和我的适配器筛选器，但筛选的列表显示不正确的项目。我的代码中是否缺少任何东西？可过滤的适配器不更新列表视图
TeamsAdapter.java
public class TeamsAdapter extends BaseAdapter implements Filterable{

TeamsFilter mFilter = new TeamsFilter();

this.context = context;
this.teamsArrayList = teamsArrayList;
this.filteredData = teamsArrayList;
}
@Override
public int getCount() {
if(filteredData == null){
return 0;
}
return filteredData.size();
}
@Override
public Team getItem(int position) {
return filteredData.get(position);
}
@Override
public long getItemId(int position) {
return filteredData.get(position).getId();
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder viewHolder;
if(convertView == null){
viewHolder = new ViewHolder();
LayoutInflater layoutInflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = layoutInflater.inflate(R.layout.team_list_item, parent, false);
viewHolder.teamNameTextView = (TextView) convertView.findViewById(R.id.team_name_textview);
convertView.setTag(viewHolder);
}
else {
viewHolder = (ViewHolder) convertView.getTag();
}
viewHolder.teamNameTextView.setText(teamsArrayList.get(position).getTeamName());
return convertView;
