I'm trying to make a message appears when the user enters the wrong username/password.
My code is working when the user enters the correct login details (it goes to the dashboard) But I want an error message to appear saying "Invalid username/password" and then and "Ok" button, once the user click on the ok button, the login page get refreshed so that the user can enter the login details again.
Please help me!!
Thats my login.java
public class Login extends ActionBarActivity implements OnClickListener {
private static final String NAMESPACE = "***";
private static final String URL = "***";
private static final String METHOD_NAME = "login";
private static final String SOAP_ACTION = NAMESPACE + "/" + METHOD_NAME; //in wsdl it's nothing
EditText usersusername, userspassword;
Button LB;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
LB = (Button) findViewById(R.id.loginbutton);
LB.setOnClickListener(this);
usersusername = (EditText)findViewById(R.id.editusername);
userspassword = (EditText)findViewById(R.id.editpassword);
}
public void onClick(View view){
if(usersusername.getText().length()==0) {
usersusername.setError("Please enter your username");
}
if(userspassword.getText().length()==0) {
userspassword.setError("Please enter your password");
}
switch (view.getId()){
case R.id.loginbutton:
new LongOperation().execute("");
break;
}
}
private class LongOperation extends AsyncTask<String, Void, String>{
@Override
protected String doInBackground(String... params) {
SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
usersusername = (EditText)findViewById(R.id.editusername);
userspassword = (EditText)findViewById(R.id.editpassword);
String user_Name = usersusername.getText().toString();
String user_Password = userspassword.getText().toString();
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("username",user_Name);//Pass properties to the variable
//Using this to add parameters "username" grabbed from WSDL
PropertyInfo passwordProp =new PropertyInfo();
passwordProp.setName("password");
passwordProp.setValue(user_Password);
passwordProp.setType(String.class);
request.addProperty(passwordProp);
SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); // Declare the version of the soap request
envelope.setOutputSoapObject(request);
try {
HttpTransportSE aht = new HttpTransportSE(URL);
aht.call(SOAP_ACTION, envelope);
SoapPrimitive result =(SoapPrimitive)envelope.getResponse(); // the result will be a session ID
String sessionid = result.toString(); // convert the session ID to a string so we can check if we got something or not
//System.out.println( Something);
if (sessionid != null )
{
Intent intent = new Intent(Login.this,Dashboard.class);
intent.putExtra("username",usersusername.getText().toString());
startActivity(intent);
}
else
{
Intent intent = new Intent(Login.this,Login.class);
startActivity(intent);
}
}
catch (Exception e){
e.printStackTrace(); }
return null;
} // closing bracket of do in background
} // closing bracket of long operation
}

AsyncTask has also an onPostExecute callback which is called when doInBackground completes. So you should handle the result here and update the UI accordingly.
private class LongOperation extends AsyncTask<String, Void, String>{
@Override
protected void onPostExecute(String param) {
if(param == null) {
// show dialog and prepare the fields for retry
}
}
}
