Question

我有一个问题，我已使用listview自定义checkbox。

当我滚动项目时，某些checkbox会自动checked，而不会点击checkbox。

任何人都可以帮助我吗？

Answer 1

这意味着你选择一个复选框，android将随机选择你应该使用...

if(tempVector.get(position)){
            holder.box.setChecked(true);
        }
        else{
            holder.box.setChecked(false);
        }

试试这个，它对我有用。

对我来说很好用

public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) {

        final ViewHolder holder;
        final Season season = (Season) getGroup(groupPosition);
        if (convertView == null) {
            LayoutInflater vi = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            convertView = vi.inflate(R.layout.season, parent, false);
            holder = new ViewHolder();
            holder.title = (TextView) convertView.findViewById(R.id.season_title);
            holder.checkBox = (CheckBox) convertView.findViewById(R.id.season_check_box);
            convertView.setTag(holder);
        } else {
            holder = (ViewHolder) convertView.getTag();
        }

        holder.title.setText(season.getTitle());
        holder.checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                season.setChecked(isChecked);
                adapter.notifyDataSetChanged();
            }
        });

        holder.checkBox.setChecked(season.isChecked()); // position is important! Must be before return statement!
        return convertView;
    }

    protected class ViewHolder {
        protected TextView title;
        protected CheckBox checkBox;
    }

滚动列表时，在列表视图中自动选中复选框。
