Я реализовал код Android, который вызывает веб-сервис SOAP.Веб-сервис принимает параметр String в форме "abc # bcd # efg #".Когда я передаю такую строку, я получаю предупреждения:
Обратите внимание: ArrayList items2 = new ArrayList ();

Из-за этого приложение запускается, но все равно я не получаю ожидаемый ответ
Мой код Android:
//Button code to insert checkbox value
alertDialog.setNegativeButton("Mark absent", new DialogInterface.OnClickListener()
{
public void onClick(DialogInterface dialog, int whichButton)
{
final Button markabsent = (Button) findViewById(R.id.Button02);
markabsent.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// Perform action on click
Toast.makeText(display.this,"You have marked the students absent",Toast.LENGTH_SHORT).show();
SparseBooleanArray checkedabsent = lView.getCheckedItemPositions();
for (int i = 0; i < arr2.length; i++)
{
if (checkedabsent.get(i))
{
System.out.println("arr2 is "+arr2[i]);
items2.add(arr2[i]);
System.out.println(items2);
s.append(arr2[i] + "#");
x=s.toString();
//s.deleteCharAt(s.length()-1);
System.out.println("absent students are\n" +s);
}
}
Log.d("", "items:");
for (String string : items2)
{
Log.d("string is", string);
}
}
});
}
});
alertDialog.show();
//Button to call web service
final Button submit = (Button) findViewById(R.id.Button03);
submit.setOnClickListener(new View.OnClickListener() {
public void onClick(View v)
{
// Perform action on click
Toast.makeText(display.this,"You have selected to submit data of students",Toast.LENGTH_SHORT).show();
ProgressDialog dialog = new ProgressDialog(display.this);
String a=call2(x);
System.out.println("A is "+a);
dialog.setMessage("Submitting data...");
dialog.show();
if(a.equalsIgnoreCase("success"))
startActivity(new Intent(display.this,End.class));
}
});
}
//web service calling method ksoap used
public String call2(String x)
{
String b="";
SoapObject request = new SoapObject(namespace, method_NAME);
request.addProperty("names",x.toString());
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.dotNet = true;
envelope.setOutputSoapObject(request);
AndroidHttpTransport android = new AndroidHttpTransport(url);
android.debug = true;
try
{
android.call(soap_ACTION, envelope);
SoapPrimitive res = (SoapPrimitive) envelope.getResponse();
SoapObject result = (SoapObject)envelope.getResponse();
Log.i("myapp",result.toString());
System.out.println(" --- response ---- " + res);
b=result.toString();

e.printStackTrace();

return b;
}
мой код веб-службы:
//splitting received array from android app and storing each value in database
public String getnames(String names)
{
SqlConnection myConnection = new SqlConnection(@"Data Source=.\SQLEXPRESS;Initial Catalog=student;User ID=sa;Password=123");
try
{
String[] s = names.Split('#');
myConnection.Open();
SqlCommand myCommand = new SqlCommand();
myCommand.Connection = myConnection;
foreach (string a in s)
{
myCommand.CommandText = "insert into record2(studentnames) values('"+a+"')";
myCommand.ExecuteNonQuery();
}
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
finally
{
myConnection.Close();
}
return "success";
}
}
Пожалуйста, помогите мне решить проблему.Спасибо
