在Android活動中的兩個列表視圖之間移動項目？

Question

我想實現待辦事項列表，在活動中需要兩個列表視圖，垂直堆疊的listview1和listview2，listview1將允許添加項目，每個項目都有一個標簽和復選框，當單擊項目的復選框時，我需要將該項目移動到listview2，現在listview2中的項目應顯示其選中的復選框，因此listview2保留選中的項目。 如果在List2中未選中該項，則應返回到list1。 我該如何實現這種行為？ 到目前為止，下面的代碼是我嘗試過的。

public class ListItem{
  String desc;
  boolean isSelected;
  //..Getters & Setters ...
}

public class ListItemAdapter extends ArrayAdapter<ListItem>  {
Context context;
List<ListItem> items = null;
List<ListItem> checkedItems = new ArrayList<ListItem>();
int layoutResourceId;

public ListItemAdapter(Context context, int layoutResourceId, List<ListItem> items) {
    super(context, layoutResourceId, items);
    this.context = context;
    this.layoutResourceId = layoutResourceId;
    this.items = items;
}

static class ViewHolder{
    protected TextView txtDesc;
    protected CheckBox checkbox;
}

@Override
public View getView(final int position, final View convertView, final ViewGroup parent) {
    View row = convertView;
 //   row.setOnClickListener(null); 

    if(row == null) {
        LayoutInflater inflater = ((Activity)context).getLayoutInflater();
        row = inflater.inflate(layoutResourceId, parent, false);

        final ViewHolder viewHolder = new ViewHolder();
        viewHolder.txtDesc = (TextView)row.findViewById(R.id.txtTitle);
        viewHolder.checkbox = (CheckBox)row.findViewById(R.id.checkBox1);
        row.setTag(viewHolder);

        viewHolder.checkbox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
                    @Override
                    public void onCheckedChanged(CompoundButton buttonView,boolean isChecked) {
                        ListItem currentItem = (ListItem) viewHolder.checkbox.getTag();
                        currentItem.setSelected(buttonView.isChecked());
                        if(currentItem.isSelected()){
                          //add item to checkedItems list
                           //remove item from uncheckedlist
                        }
                        notifyDataSetChanged();
                    }
                });
    }else{
        row = convertView;
        ((ViewHolder) row.getTag()).checkbox.setTag(items.get(position));
    }

    ListItem item = items.get(position);
    ViewHolder holder = (ViewHolder) row.getTag();
    holder.txtDesc.setText(item.getDesc());
    holder.checkbox.setSelected(item.isSelected());

    return row;
}

Answer 1

我這樣做：
在列表視圖中的項目：item.setId（youId）;
然后在onClickListener {onClick（View v）{v.getId（）;}}中

如果其他人正在尋找答案，這是我的解決方案。
