如何在listview中包含更多的表字段？

我帶兩個字段webservice和填充listview。如何在listview中包含更多的表字段？

我需要一個多行的textview。我的組件足夠大，可顯示至少4行，但只顯示2行。

如何在listview中添加更多的子項？

我想在listview中包含更多的表字段。

private void pesquisarProdutos() { 
    dialog = ProgressDialog.show(this, "Aguarde...", 
      "Pesquisando registros.", false, true); 
    dialog.setIcon(R.drawable.ic_launcher); 
    dialog.setCancelable(false); 

    DSRESTConnection conn = gc.getConnection(); 
    final TServerMethods1 serv = new TServerMethods1(conn); 

    new AsyncTask<Void, Void, Void>() { 

     @Override 
     protected Void doInBackground(Void... params) { 
      try { 
       TDataSet ds; 
       // limpa a lista a cada pesquisa 
       dataList.clear(); 
       ds = serv.ConsultaItens(VendaClienteActivity.edtItem 
         .getText().toString()); 
       while (ds.next()) { 
        HashMap<String, String> item = new HashMap<String, String>(); 
        item.put("nome", ds.getValue("NOME").GetAsString()); 
        item.put("id", ds.getValue("CODIGO").GetAsString()); 
        dataList.add(item); 
       } 
       // desabilita o dialog 
       dialog.dismiss(); 
       finalizaDialogo(false, ""); 

      } catch (Exception e) {// desabilita o dialog 
       dialog.dismiss(); 
       finalizaDialogo(true, e.toString()); 
      } 
      return null; 
     } 
    }.execute(); 
} 

private void finalizaDialogo(final boolean temErro, final String msg) { 
    handler.post(new Runnable() { 

     @Override 
     public void run() { 
      if (temErro) 
       Toast.makeText(ListaItensProdutosActivity.this, msg, 
         Toast.LENGTH_LONG).show(); 
      else 
       AtualizarTela(); 
      // finaliar o dialogo 
      dialog.dismiss(); 
     } 
    }); 
} 

private void AtualizarTela() { 
    String[] from = new String[] { "nome", "id" }; 
    int[] to = new int[] { android.R.id.text1, android.R.id.text2 }; 
    int layoutNativo = android.R.layout.two_line_list_item; 

    listItens.setAdapter(new SimpleAdapter(this, dataList, layoutNativo, 
      from, to)); 

    if (listItens == null) { 

     Toast.makeText(ListaItensProdutosActivity.this, 
       "Não foi encontrado dados nesta busca.", Toast.LENGTH_LONG) 
       .show(); 
     finish(); 

    } 

}

我的XML

你需要一個定製的適配器列表https://github.com/cplain/custom-list是一個粗略的例子，我做了一個朋友，希望這可以幫助

幾乎工作，再加上我而不是正確地帶來這一點。

帶來只有表

這裏的最後一個記錄是我如何做類活動

public class ListaPacoteActivity extends ListActivity { 

    private GetConnection gc = new GetConnection(); 
    private Context pacoteList; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     this.requestWindowFeature(Window.FEATURE_NO_TITLE); 
     this.getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN); 
     this.getWindow().clearFlags(
       WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN); 
     setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); 

     List<Pacotes> pacoteList = new ArrayList<Pacotes>(); 

     DSRESTConnection conn = gc.getConnection(); 
     TServerMethods1 serv = new TServerMethods1(conn); 
     TDataSet ds; 
     // String idCharCodCli = VendaClienteActivity.edtCliente.getText() 
     // .toString(); 
     // String[] idNumCli = idCharCodCli.split("-"); 
     // String idCharCodPro = VendaClienteActivity.edtProfissional.getText() 
     // .toString(); 
     // String[] idNumPro = idCharCodPro.split("-"); 
     try { 
      ds = serv.ConsultaDadosPacote("1000", "4");// idNumCli[0], 
                 // idNumPro[0]); 
      Pacotes pct = new Pacotes(); 

      while (ds.next()) { 
       String concPacote = ds.getValue("CODIGO_PACOTE").toString() 
         + " - " + ds.getValue("NOME_PACOTE").toString(); 
       String concSessao = "Sessão: " 
         + ds.getValue("CODIGO_SERVICO").toString() + " - " 
         + ds.getValue("NOME_SERVICO").toString(); 
       String concCreditos = "Créditos restantes: " 
         + ds.getValue("CREDITOS_RESTANTES").toString(); 
       String concStatus = "Status: " 
         + ds.getValue("STATUS").toString(); 
       String concHabilidade = "Habilidade: " 
         + ds.getValue("HABILIDADE").toString() + " - " 
         + ds.getValue("CODIGO_COMPRA").toString(); 
       pct.setPacote(concPacote); 
       pct.setSessao(concSessao); 
       pct.setCreditos(concCreditos); 
       pct.setStatus(concStatus); 
       pct.setHabilidade(concHabilidade); 
       // adiciona os dados no list 
       pacoteList.add(pct); 
      } 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
     setListAdapter(new PacoteAdapter(getBaseContext(), pacoteList)); 
    } 

}

POJO的

public class Pacotes { 
    private String pacote = ""; 
    private String sessao = ""; 
    private String creditos = ""; 
    private String status = ""; 
    private String habilidade = ""; 
    public String getPacote() { 
     return pacote; 
    } 
    public void setPacote(String pacote) { 
     this.pacote = pacote; 
    } 
    public String getSessao() { 
     return sessao; 
    } 
    public void setSessao(String sessao) { 
     this.sessao = sessao; 
    } 
    public String getCreditos() { 
     return creditos; 
    } 
    public void setCreditos(String creditos) { 
     this.creditos = creditos; 
    } 
    public String getStatus() { 
     return status; 
    } 
    public void setStatus(String status) { 
     this.status = status; 
    } 
    public String getHabilidade() { 
     return habilidade; 
    } 
    public void setHabilidade(String habilidade) { 
     this.habilidade = habilidade; 
    } 
}

類適配器

public class PacoteAdapter extends BaseAdapter { 
    private Context context; 
    private List<Pacotes> pacoteList; 

    public PacoteAdapter(Context context, List<Pacotes> pacotelist){ 
     this.context = context; 
     this.pacoteList = pacotelist; 
    } 

    @Override 
    public int getCount() { 
     return pacoteList.size(); 
    } 

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

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

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     // Recupera o pacote da posição atual 
     Pacotes pct = (Pacotes) getItem(position); 

     // Cria uma instância do layout XML para os objetos correspondentes 
     // na View 
     LayoutInflater inflater = (LayoutInflater) context 
       .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

     View view = inflater.inflate(R.layout.custom_row_view, null); 
     // pacote 
     TextView textPacote = (TextView) view.findViewById(R.id.pacote); 
     textPacote.setText(pct.getPacote()); 
     //sessão 
     TextView textSessao = (TextView) view.findViewById(R.id.sessao); 
     textSessao.setText(pct.getSessao()); 
     //creditos 
     TextView textCredito = (TextView) view.findViewById(R.id.credito); 
     textCredito.setText(pct.getPacote()); 
     //status 
     TextView textStatus = (TextView) view.findViewById(R.id.status); 
     textStatus.setText(pct.getStatus()); 
     //habilidade 
     TextView textHabilidade = (TextView) view.findViewById(R.id.habilidade); 
     textHabilidade.setText(pct.getHabilidade()); 

     return view; 
    } 
}

是XML

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:orientation="vertical" > 

    <TextView 
     android:id="@+id/pacote" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:textColor="#0000FF" 
     android:textSize="14sp" 
     android:textStyle="bold" /> 

    <TextView 
     android:id="@+id/sessao" 
     android:textColor="#228B22" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" /> 

    <TextView 
     android:id="@+id/credito" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" /> 

    <TextView 
     android:id="@+id/status" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" /> 

    <TextView 
     android:id="@+id/habilidade" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" /> 

</LinearLayout>
