Android List View自定义适配器，带有复选框多个选择和Search Listview

Question

我已经实现了具有自定义采用者类和多个复选框选择的ListView 。 它的工作正常。 之后，我在ListView中给出了搜索名称。 如果我选中了行项目，则在搜索中搜索名称，搜索位置已更改。 请帮助我解决此问题。

 @Override

          if(isChecked){

             group.setChecked(true);
             int pos = originalList.indexOf(group)
             originalList.get(pos).setChecked(true);

使用SparseBooleanArray更新您的适配器

    public class FullUserAdapter extends ArrayAdapter<FullUser> {
    private ArrayList<FullUser> originalList;
    private ArrayList<FullUser> fullUsers;
    private SubjectFilter filter;
    SparseBooleanArray booleanArray ;


    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);
             }
         }
         return list;

    };
