嗨，我已经成功开发了一个 listview 应用程序..现在我必须单击该列表中的任何项目，这意味着详细描​​述会显示在下一个活动中...它也已成功完成..现在我的输出格式如下：

1   F   Krishna
2   Q   Danesh
3   P   Mercy

在这里，我必须单击2 Q Danesh项目，它是转到下一个活动。下一个活动必须显示

Q Danesh

它成功地工作了。

但现在我希望需要这种格式的列表视图：

1 Krishna
2 Danesh
3 Mercy

在这里我必须点击2 Danesh表示它是进入下一个活动并且下一个活动必须显示

Q

我该怎么办……请帮帮我……

下面的代码是我的网络服务代码：

 public class RetailerWs {
 public String customerData1(){
 String customerInfo = "";
 try{
 Class.forName("com.mysql.jdbc.Driver");
 Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/xcart-432pro","root","");

//查找客户ID最大的客户信息 PreparedStatement statement = con.prepareStatement("SELECT * FROM xcart_orders"); ResultSet 结果 = statement.executeQuery();

 while(result.next()){
   customerInfo = customerInfo 
            + result.getString("orderid") 
            + " "   // this to separate order id from status
            + result.getString("status") 
            + " " 
    // this to separate order id from status
            + result.getString("login") 
            + "&" ;
 //Here "&"s are added to the return string. This is help to split the string in Android application
}
}

catch(Exception exc){
System.out.println(exc.getMessage());
}

return customerInfo;
}

 }

这是我的安卓代码：

public class RetailerActivity extends Activity {
ListView list;
private static final String SOAP_ACTION = "http://xcart.com/customerData1";
private static final String METHOD_NAME = "customerData1";
private static final String NAMESPACE = "http://xcart.com";
private static final String URL = "http://192.168.1.168:8089/XcartLogin/services/RetailerWs?wsdl";
private static final String KEY_STATUS = "status";
private static final String KEY_LOGIN = "login";


/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); 

    SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);

    envelope.setOutputSoapObject(request);

    HttpTransportSE ht = new HttpTransportSE(URL);
    try {
        ht.call(SOAP_ACTION, envelope);
        SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
        SoapPrimitive s = response;
        String str = s.toString();
        String resultArr[] = str.split("&");
        list=(ListView)findViewById(R.id.list);


        list.setAdapter(new ArrayAdapter(this, android.R.layout.simple_list_item_1,resultArr));
        list.setOnItemClickListener(new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view,
                    int position, long id) {
                String status =  parent.getItemAtPosition(position).toString();

                String[] status1  = status.split(" ");

                 String StrStatus = status1[1].toString();

                Intent in = new Intent(getApplicationContext(), SingleMenuItemActivity.class);
                in.putExtra(KEY_STATUS, StrStatus);

                startActivity(in);            



            }
        });     
    }


    catch (Exception e) {
        e.printStackTrace();
    }
}

  }

这是我的下一个活动： 

 public class SingleMenuItemActivity  extends Activity {

// XML node keys
static final String KEY_STATUS = "status";

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

    Intent in = getIntent();
    String StrStatus = in.getStringExtra(KEY_STATUS);


    // Displaying all values on the screen
    TextView lblName = (TextView) findViewById(R.id.status_label);
    lblName.setText(StrStatus);

  }
  }

请帮我....

有可能的。您可以将 Q 从列表屏幕带到其他活动。

你只需要改变你的第一个活动（这是你的 Q 值）

in.putExtra("StrStatus", StrStatus);

然后你可以在你的其他活动中通过

Bundle extras=getIntent().getExtras();
if(extras!=null) {
    STRStatus=extras.getString("StrStatus");
}

这将有你的 Q 值，你可以做任何你想做的事情。

-----
BTW - 你得到哪个错误？您可以使用它来单击您的列表项

public void onListItemClick(ListView parent,View v,int position,long id){
try {
    TextView t4=(TextView)v.findViewById(R.id.No);

    if (t4!=null){
        BeanClass/*ClassName*/  mSelected;
        int idx=position;
        mSelected=m_adapter.getItem(idx);           
        String ActionID=mSelected.getID();

        Intent intent=new Intent(this,SoneActivity.class);
        intent.putExtra("StrStatus", StrStatus);
        startActivity(intent);
    }
}
