我已经使用自定义采用者类和多个复选框选择实现了ListView。它的工作正常。之后，我在 ListView 中搜索了名称。如果我检查了行项目，那么我在搜索中搜索名称，搜索位置已更改。请帮我解决这个问题。
模型类

private ArrayList<FullUser> originalList;
private ArrayList<FullUser> fullUsers;

public FullUserAdapter(Context context, int resource, ArrayList<FullUser> fullUsers) {
super(context, resource, fullUsers);
this.fullUsers = new ArrayList<FullUser>();
this.fullUsers.addAll(fullUsers);
this.originalList = new ArrayList<FullUser>();
this.originalList.addAll(fullUsers);
booleanArray = new SparseBooleanArray();
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
.
.
.
final FullUser group =getItem(position);
holder.groupid.setText(group.getId());
holder.checkBox.setOnCheckedChangeListener(null);
holder.checkBox.setChecked(booleanArray.get(group.getId().hashCode(),false));
holder.checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
booleanArray.put(group.getId().hashCode(), isChecked);
}
});
.
.
.
return row;
}
public ArrayList<FullUser> getSelectedItems() {
ArrayList<FullUser> list = new ArrayList<>();
for(FullUser group:fullUsers){
if(booleanArray.get(group.getId().hashCode(), false)){
list.add(group);
