Question

我对Android编程很新，我遇到了一个小问题。我有一个arraylist包含从多选列表视图中选择的人的名字，问题是每当我将这些arraylist值插入数据库时，它会将其作为一个字符串插入： Database row。我如何通过arraylist进行迭代，同时将其值插入数据库？

这是我的代码：

try {
 Connection con = connectionClass.CONN();
  if (con == null) {
   Toast.makeText(getApplicationContext(), "CONNECTION FAIL", Toast.LENGTH_LONG).show();
   } else {

  String samp = "";
  String names = "";
  samp = myArrayAdapter.getCheckedItems().toString();
  ArrayList<String> data1 = new ArrayList<String>();
  data1.add(samp);

  for(int x=0; x<data1.size(); x++)
   {
      names += String.valueOf(data1.get(x));
      String query = "INSERT INTO AUTOINC(PersonName)"+"VALUES('"+names+"')";
      PreparedStatement preparedStatement = con.prepareStatement(query);
                        preparedStatement.executeUpdate();

   }
      Toast.makeText(getApplicationContext(), "INSERT SUCCESS", Toast.LENGTH_LONG).show();
      }
    } catch (Exception ex) {
    Toast.makeText(getApplicationContext(), "INSERT FAILED", Toast.LENGTH_LONG).show();
    Log.e("MYAPP", "exception", ex);
   }

感谢您今后的任何回复。

Answer 1

你可以试试吗？

List<String> data1 = new ArrayList<String>(Arrays.asList(samp.replace("[","").replace("]","").split(",")));

for (String name : data1) {
  names += name;   // This lines concatenate the name.
 //If you want to insert single name the you can directly insert the name value into databas.  
  String query = "INSERT INTO AUTOINC(PersonName)"+"VALUES('"+name+"')";
  PreparedStatement preparedStatement =   con.prepareStatement(query);
  preparedStatement.executeUpdate();
}

看看这段代码......

 SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);        
                    PropertyInfo pi=new PropertyInfo();
                    pi.setName("UserName");
                    pi.setValue(txtName.getText().toString());
                    pi.setType(String.class);
                    request.addProperty(pi);
                    pi=new PropertyInfo();
                    pi.setName("UserAge");
                    pi.setValue(txtVal.getText().toString());
                    pi.setType(String.class);
                    request.addProperty(pi);


SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
            envelope.dotNet = true;
            envelope.setOutputSoapObject(webRequest);
            HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);


    androidHttpTransport.call(SOAP_ACTION + METHOD_NAME, envelope);
    Log.d("CheckLogin-SOAP ACTION", SOAP_ACTION + METHOD_NAME);
    SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
    Log.d("CheckLogin - Response", response.toString());

    status= Boolean.valueOf(response.toString());
