java - 无法收集 java/android 中 int 数组的值

Question

我正在尝试通过使用它来收集 int 数组中的一些值，这些值来自 Web 服务。这里我使用 SOAP 方法进行消费。

当我尝试收集 int 数组中的值时，我无法运行模拟器。

如何克服这个错误？请找到我的来源以供引用。

Main_WB.java

 public class Main_WB extends Activity 
 {
EditText edt1,edt2;
TextView txt_1;
Button btn;

 @Override
 public void onCreate(Bundle savedInstanceState) 
 {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    edt1 = (EditText)findViewById(R.id.editText1);
    edt2 = (EditText)findViewById(R.id.editText2);
    btn = (Button)findViewById(R.id.button1);

    btn.setOnClickListener(new View.OnClickListener()
    {
    public void onClick(View v) 
    {
        getTMSChart(edt1.getText().toString(),edt2.getText().toString());
    }     
    });
  }

 private void getTMSChart(String FromDate,String ToDate)
 {
     txt_1 = (TextView)findViewById(R.id.textView1);

     System.setProperty("http.keepAlive", "false");        
     SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);        

     envelope.dotNet = true;

     String NAMESPACE = "http://tempuri.org/";
     String URL = "http://54.251.60.177/TMSOrdersService/TMSDetails.asmx";
     String METHOD = "GetTMSChart";

     SoapObject request = new SoapObject(NAMESPACE, METHOD);        
     request.addProperty("FromDate", FromDate);               
     request.addProperty("ToDate", ToDate);

     envelope.setOutputSoapObject(request);
     HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);

     try 
     {
         androidHttpTransport.call(NAMESPACE + METHOD, envelope);

         SoapObject result = (SoapObject) envelope.bodyIn;

         SoapObject root =  (SoapObject) ((SoapObject)(result).getProperty(0)).getProperty("NewDataSet");

         int tablesCount = root.getPropertyCount();


      for (int i = 0; i < tablesCount; i++)
      {
         SoapObject table = (SoapObject) root.getProperty(i);
         int propertyCount = table.getPropertyCount();

      for (int j = 0; j < propertyCount; j++)
      {           

    //  String orderNo =  table.getPropertyAsString("Order_No");
    //  String freight =  table.getPropertyAsString("Freight_Rate");
    //  String percent =  table.getPropertyAsString("Margin_Percent");


       int orderNo = Integer.parseInt(table.getPropertyAsString("Order_No"));
       int freightRate = Integer.parseInt(table.getPropertyAsString("Freight_Rate"));
       int marginPercent = Integer.parseInt(table.getPropertyAsString("Margin_Percent"));

       int[] ord = new int[orderNo];
       int[] frei = new int[freightRate];
       int[] margin = new int[marginPercent];


     // whatever you do with these values

       txt_1.setText(ord);
       txt_1.setText(frei);
       txt_1.setText(margin);
          }                   
       }
    }   
    catch (Exception e) 
    {
    }   
    }    }

这是一个编译错误，并且该错误是不言自明的:

The method setText(CharSequence) in the type TextView is not applicable for the arguments (int[])

这意味着方法 setText() 的参数必须为 CharSequence 类型，但您使用 int[] 类型的参数调用它，其中不是 CharSequence。

将 int[] 数组转换为字符串，并且当 String 实现 CharSequence 时，将结果字符串传递给 setText()。例如:

txt_1.setText(Arrays.toString(ord));

此外，我真的不明白在同一文本字段上使用三个不同参数调用 setText() 有什么意义。
