Android 从listview获取下一个和上一个详细信息数据

我不知道如何通过单击基于listview的下一个/上一个按钮来创建显示下一个/上一个详细信息数据的函数

这是我想做的截图

，以显示listview中的下一个/上一个数据

编辑：我有一个listview数据（使用xml解析器），并将数据传递给名为“Detail_toko.class”的新活动：

List parameter=new ArrayList（）；
添加（新的BasicNameValuePair（“关键字”，“a”））；
//添加（新的BasicNameValuePair（“kategori”，Category.getSelectedItem（）.toString（））；
XMLParser=新的XMLParser（）；
字符串xml=parser.getXmlFromUrl（URL，参数表）；//从URL获取XML
Document doc=parser.getdoElement（xml）；//获取DOM元素
NodeList nl=doc.getElementsByTagName（标记详细信息）；
//循环通过所有歌曲节点
对于（int i=0；ivalue
put（TAG_ID，parser.getValue（e，TAG_ID））；
put（TAG_NAMATOKO，parser.getValue（e，TAG_NAMATOKO））；
put（TAG_KATEGORI，parser.getValue（e，TAG_KATEGORI））；
map.put（TAG_EMAIL，parser.getValue（e，TAG_EMAIL））；
put（TAG_图标，parser.getValue（e，TAG_图标））；
//将哈希列表添加到ArrayList
PremiumList.add（地图）；
} 
返回null；
}
/**
*将解析的JSON数据更新到ListView中
* */
list=（ListView）findViewById（R.id.ListView）；
如果（PremiumList.size（）>0）
{
adapter=新LazyAdapterStore（ListPerusahaan.this，PremiumList）；
list.setAdapter（适配器）；
}
其他的
{
Toast Toast=Toast.makeText（getApplicationContext（），“未找到数据，请输入另一个关键字”，Toast.LENGTH\u SHORT）；
toast.setGravity（重力。重心垂直|重力。重心水平，0,0）；
toast.show（）；
}
//单击单个列表行的事件
list.setOnItemClickListener（新的OnItemClickListener（）{
@凌驾
public void onItemClick（AdapterView父级、视图、，
内部位置，长id）{
//从选定的ListItem获取值
字符串nama_-toko=（（TextView）view.findViewById（R.id.nama_-toko））.getText（）.toString（）；
字符串kategori=（（TextView）view.findviewbyd（R.id.kategori））.getText（）.toString（）；
字符串email=（（TextView）view.findviewbyd（R.id.email））.getText（）.toString（）；
PremiumList=newarraylist（）；
意向in=新意向（ListPerusahaan.this，Detail_toko.class）；
in.putExtra（“PremiumList”，PremiumList）；
//in.putStringArrayListExtra（“PremiumList”，PremiumList）；
in.putExtra（“位置”，位置）；
in.putExtra（“TotalData”，TotalData）；
in.putExtra（TAG_NAMATOKO，nama_toko）；
in.putExtra（TAG_KATEGORI，KATEGORI）；
in.putExtra（标记电子邮件、电子邮件）；
星触觉（in）；

这是我的LazyAdapterStore代码：

  public View getView(int position, View convertView, ViewGroup parent) {
    View vi=convertView;
    if(convertView==null)
        vi = inflater.inflate(R.layout.list_data_store, null);

    TextView nama_toko = (TextView)vi.findViewById(R.id.nama_toko); // title
    TextView kategori = (TextView)vi.findViewById(R.id.kategori); // title
    ImageView thumb_image=(ImageView)vi.findViewById(R.id.list_image); // thumb image
    TextView email = (TextView)vi.findViewById(R.id.email); // artist name


    HashMap<String, String> detail = new HashMap<String, String>();
    detail = data.get(position);


    // Setting all values in listview
    nama_toko.setText(detail.get(ListPerusahaan.TAG_NAMATOKO));
    kategori.setText(detail.get(ListPerusahaan.TAG_KATEGORI));
    email.setText(detail.get(ListPerusahaan.TAG_EMAIL));
    imageLoader.DisplayImage(detail.get(ListPerusahaan.TAG_ICON), thumb_image);
    return vi;

}

public View getView（int位置、视图转换视图、视图组父视图）{
视图vi=转换视图；
if（convertView==null）
vi=充气机充气（R.layout.list\u data\u store，空）；
TextView-nama_-toko=（TextView）vi.findViewById（R.id.nama_-toko）；//标题
TextView kategori=（TextView）vi.findviewbyd（R.id.kategori）；//title
ImageView thumb_image=（ImageView）vi.findViewById（R.id.list_image）；//thumb image
TextView电子邮件=（TextView）vi.findviewbyd（R.id.email）；//艺术家姓名
HashMap detail=新的HashMap（）；
detail=data.get（位置）；
//在listview中设置所有值
nama_toko.setText（detail.get（listpurusahaan.TAG_NAMATOKO））；
setText（detail.get（listpureusahaan.TAG_kategori））；
email.setText（detail.get（listpurusahaan.TAG_email））；
imageLoader.DisplayImage（detail.get（ListPerusahaan.TAG_图标）、thumb_图像）；
返回vi；
}
