嗨，在我的应用程序中，我试图从webservice检查数据库中的用户名和密码，如果它的真实将显示成功消息或失败的消息，但无法显示状态消息
public class AndroidLoginExampleActivity extends Activity {
private final String NAMESPACE = "http://ws.userlogin.com";
private final String URL = "http://localhost:8080/Androidlogin/services/Login?wsdl";
private final String SOAP_ACTION = "http://ws.userlogin.com/authentication";
private final String METHOD_NAME = "authentication";
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button login = (Button) findViewById(R.id.btn_login);
login.setOnClickListener(new View.OnClickListener() {
public void onClick(View arg0) {
loginAction();
}
});
}
@SuppressLint("NewApi") private void loginAction(){
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
EditText userName = (EditText) findViewById(R.id.tf_userName);
String user_Name = userName.getText().toString();
EditText userPassword = (EditText) findViewById(R.id.tf_password);
String user_Password = userPassword.getText().toString();
//Pass value for userName variable of the web service
PropertyInfo unameProp =new PropertyInfo();
unameProp.setName("userName");//Define the variable name in the web service method
unameProp.setValue(user_Name);//set value for userName variable
unameProp.setType(String.class);//Define the type of the variable
request.addProperty(unameProp);//Pass properties to the variable
//Pass value for Password variable of the web service
PropertyInfo passwordProp =new PropertyInfo();
passwordProp.setName("password");
passwordProp.setValue(user_Password);
passwordProp.setType(String.class);
request.addProperty(passwordProp);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
envelope.setOutputSoapObject(request);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
try{
androidHttpTransport.call(SOAP_ACTION, envelope);
SoapPrimitive response = (SoapPrimitive)envelope.getResponse();
TextView result = (TextView) findViewById(R.id.tv_status);
result.setText(response.toString());
Log.d("resp:",response.toString() );
}
catch(Exception e){
}
}
下面是我的网络服务电话
public class Login {
public String authentication(String userName,String password){
String retrievedUserName = "";
String retrievedPassword = "";
String status = "";
try{
Class.forName("com.mysql.jdbc.Driver");
Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/mydb","root","root");
PreparedStatement statement = con.prepareStatement("SELECT * FROM user WHERE username = '"+userName+"'");
ResultSet result = statement.executeQuery();
while(result.next()){
retrievedUserName = result.getString("username");
retrievedPassword = result.getString("password");
}
if(retrievedUserName.equals(userName)&&retrievedPassword.equals(password)){
status = "Success!";
}
else{
status = "Login fail!!!";
}
}
catch(Exception e){
e.printStackTrace();
}
return status;
}
}
不确定我做错了。感谢任何帮助。

您应该在线程上进行网络实际操作。您可以使用thread或AsyncTask。
将loginAction()移到thread内或doInbackground AsyncTask内。
请记住不要从后台线程更新ui。
new TheTask().execute();
的AsyncTask
public class TheTask extends AsyncTask <Void,Void,Void>
{
@Override
protected void onPreExecute() {
super.onPreExecute();
// display a dialog
}
@Override
protected Void doInBackground(Void... params) {
// your login authentcation
// remove updation of textview.
// do not update ui here
return null;
}
@Override
protected void onPostExecute(Void result) {
super.onPostExecute(result);
// dismiss the dialog
// update textview
}
}
AsyncTask docs
