android - ListView 中的数据在焦点更改时从顶行移动到底行

Question

我正在使用具有 TextView 和编辑文本的 ListView 。我通过 ViewHolder 控制其中的数据。问题是，当我在第一列和第二列中写入数据时，在屏幕上可见的部分以及滚动时，第一行的数据会自动复制到最后一行。

代码如下:

private class MobileArrayAdapter extends ArrayAdapter
{
    ViewHolder holder;
    private Context context;
    private ArrayList values;

    @SuppressWarnings("unchecked")
    public MobileArrayAdapter(Context context, ArrayList values)
    {
        super(context, R.layout.taskstrt, values);
        this.context = context;
        this.values = values;
        System.out.println("in mobile constructor");
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent)
    {
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        if (convertView == null)
        {
            holder = new ViewHolder();
            convertView = inflater.inflate(R.layout.taskstrt, parent, false);
            holder.editText = (EditText) convertView.findViewById(R.id.editText1);
            holder.textView = (TextView) convertView.findViewById(R.id.textView1);
            convertView.setTag(holder);
        }
        else
        {
            holder = (ViewHolder) convertView.getTag();
        }

        holder.textView.setText(values.get(position).toString());
        holder.textView.setId(position);
        holder.editText.setId(position);
        holder.editText.setFocusable(false);
        // holder.editText.setFocusableInTouchMode(true);

        holder.editText.setOnClickListener(new OnClickListener()
        {
            public void onClick(View v)
            {
                final int positio = v.getId();
                edittexthold = (EditText) v;
                textholder = (TextView) v;
                edittexthold.setFocusable(true);

                if (edittexthold.getText().toString().length() > 0)

                {
                    HashMap<Integer, String> Map = new HashMap<Integer, String>();
                    Map.put(positio, edittexthold.getText().toString());

                    data.set(positio, Map);
                    System.out.println(data);
                }

                System.out.println(positio + " this is position that is clicked");
                if (positio == 4)
                {
                    System.out.println("going to assign ID");
                    qq = positio;
                    showDialog(NAME_LIST);
                }

                if (positio == 5)
                {
                    qq = positio;
                    System.out.println("going to start time ID");
                    showDialog(STARTTIME);
                }

                if (positio == 3)
                {
                    qq = positio;
                    System.out.println("going to date picker ID");
                    showDialog(DATE_DIALOG_ID);
                }
            }
        }) ;
        holder.editText.setOnFocusChangeListener(new OnFocusChangeListener()
        {

            public void onFocusChange(View v, boolean hasFocus)
            {
                //if(!hasFocus)
                {
                    final int positio = v.getId();
                    String conv = null;
                    final EditText edittexthold = (EditText) v;
                    final TextView textholder = (TextView) v;
                    edittexthold.setFocusable(true);

                    if (edittexthold.getText().toString().length() > 0)

                    {
                        HashMap<Integer, String> Map = new HashMap<Integer, String>();
                        Map.put(positio, edittexthold.getText().toString());

                        data.set(positio, Map);
                        System.out.println(data);
                    }

                    edittexthold.setFocusable(false);
                }
            }
        });
