Android Listview条目重复

用户名

对于android编程来说是相当新的东西，我有一个Listview，其值正在我的代码中填充，但是每当方向更改或恢复时，列表条目就会被重新填充（导致条目重复），我该如何解决这个问题

在这里，根据您的要求，您可以看到一个示例适配器，该适配器已将ViewHolder用于ListView：

public class AllCustomerListCustomAdapter extends SimpleCursorAdapter {

private Cursor c;                       // Passed in cursor
private Activity context;


public CustomAdapter(Activity context, int layout, Cursor c,
        String[] from, int[] to) {

    super(context, layout, c, from, to);
    this.c = c;
    this.context = context;

    c.moveToFirst();
}

static class ViewHolder 
{
    public TextView rowView1;
    public TextView rowView2;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    ViewHolder holder;
    View rowView = convertView;
    c.moveToPosition(position);


    if (rowView == null) 
    {
        LayoutInflater inflater = (context).getLayoutInflater();
        rowView = inflater.inflate(R.layout.listview_row, null, true);
        holder = new ViewHolder();
        holder.rowView1 = (TextView) rowView.findViewById(R.id.txtListItem1);
        holder.rowView2 = (TextView) rowView.findViewById(R.id.txtListItem2);

        rowView.setTag(holder);
    }
    else
    {
        holder = (ViewHolder) rowView.getTag();
    }
    holder.rowView1.setText(c.getString(c.getColumnIndex(DBAdapter.KEY_VIEW1)));
    holder.rowView2.setText(c.getString(c.getColumnIndex(DBAdapter.KEY_VIEW2)));


return rowView;
}
