ListView显示SIM相关信息

适配器代码:

public class MyAdapter extends BaseAdapter
{

  private LayoutInflater mInflater;

  private List<String> values;

  /* MyAdapter的构造器，传入三个参数 */
  public MyAdapter(Context context, List<String> item,
      List<String> value)
  {
    /* 参数初始化 */
    mInflater = LayoutInflater.from(context);
    items = item;
    values = value;
  }

  /* 因继承BaseAdapter，需覆盖以下方法 */
  @Override
  public int getCount()
  {
    return items.size();
  }

  @Override
  public Object getItem(int position)
  {
    return items.get(position);
  }

  @Override
  public long getItemId(int position)
  {
    return position;
  }

  @Override
  public View getView(int position, View convertView, ViewGroup par)
  {
    ViewHolder holder;

    if (convertView == null)
    {
      /* 使用自定义的file_row作为Layout */
      convertView = mInflater.inflate(R.layout.row_layout, null);
      /* 初始化holder的text与icon */
      holder = new ViewHolder();
      holder.text1 = (TextView) convertView.findViewById(R.id.myText1);
      holder.text2 = (TextView) convertView.findViewById(R.id.myText2);

      convertView.setTag(holder);
    } else
    {
      holder = (ViewHolder) convertView.getTag();
    }
    holder.text1.setText(items.get(position).toString());
    holder.text2.setText(values.get(position).toString());

    return convertView;
  }

  private class ViewHolder
  {
    TextView text1;
    TextView text2;
  }
