I am using eclipse and the latest sdk.
Basically I am trying to produce a login/register script, what happens so far is my app loads correctly and the correct layout is displayed, I can fill in the details but neither my register or login button works.
I think that what I need to do is register my login class somewhere in my MainActivity, but I am not sure how I would do this and keep my class seperate??
Main Activity:
@SuppressWarnings("unused")
public class MainActivity extends Activity
{
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.welcome_screen);
}
}
Login:
public class Login extends Activity implements OnClickListener
{
private EditText EmailAddress, Password;
private Button mSubmit, mRegister;
private ProgressDialog pDialog;
JSONParser jsonParser = new JSONParser();
private static final String LOGIN_URL = "http://www.hotelwifiscore.com/app/login.php";
private static final String TAG_SUCCESS = "success";
private static final String TAG_MESSAGE = "message";
private static final String TAG_UserID = "User_ID";
private static final String TAG_Premium = "Premium";
@Override
protected void onCreate(Bundle savedInstanceState)
{
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.welcome_screen);
//setup input fields
EmailAddress = (EditText)findViewById(R.id.email_Address);
Password = (EditText)findViewById(R.id.password);
//setup buttons
mSubmit = (Button)findViewById(R.id.login);
mRegister = (Button)findViewById(R.id.register);
//register listeners
mSubmit.setOnClickListener(this);
mRegister.setOnClickListener(this);
}
@Override
public void onClick(View v)
{
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.login:
new AttemptLogin().execute();
break;
case R.id.register:
new CreateUser().execute();
break;
default:
break;
}
}
AttemptLogin:
class AttemptLogin extends AsyncTask<String, String, String>
{
boolean failure = false;
@Override
protected void onPreExecute()
{
super.onPreExecute();
pDialog = new ProgressDialog(Login.this);
pDialog.setMessage("Attempting login...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
@Override
protected String doInBackground(String... args)
{
int success;
String EmailA = EmailAddress.getText().toString();
String PassW = Password.getText().toString();
try
{
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("Email_Address", EmailA));
params.add(new BasicNameValuePair("Password", PassW));
Log.d("request!", "starting");
JSONObject json = jsonParser.makeHttpRequest(LOGIN_URL, "POST", params);
Log.d("Login attempt", json.toString());
success = json.getInt(TAG_SUCCESS);
if (success == 1)
{
Log.d("Login Successful!", json.toString());
Intent i = new Intent(Login.this, UserHome.class);
finish();
startActivity(i);
return json.getString(TAG_MESSAGE);
}
else
{
Log.d("Login Failure!", json.getString(TAG_MESSAGE));
return json.getString(TAG_MESSAGE);
}
}
catch (JSONException e)
{
e.printStackTrace();
}
return null;
}
}
CreateUser:
class CreateUser extends AsyncTask<String, String, String>
{
boolean failure = false;
@Override
protected void onPreExecute()
{
super.onPreExecute();
pDialog = new ProgressDialog(Login.this);
pDialog.setMessage("Creating User...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(true);
pDialog.show();
}
@Override
protected String doInBackground(String... args)
{
int success;
String EmailA = EmailAddress.getText().toString();
String PassW = Password.getText().toString();
try
{
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("Email_Address", EmailA));
params.add(new BasicNameValuePair("Password", PassW));
Log.d("request!", "starting");
JSONObject json = jsonParser.makeHttpRequest(LOGIN_URL, "POST", params);
Log.d("Login attempt", json.toString());
success = json.getInt(TAG_SUCCESS);
if (success == 1)
{
Log.d("User Created!", json.toString());
finish();
return json.getString(TAG_MESSAGE);
}
else
{
Log.d("Login Failure!", json.getString(TAG_MESSAGE));
return json.getString(TAG_MESSAGE);
}
}
catch (JSONException e)
{
e.printStackTrace();
}
return null;
}
}
/**
* After completing background task Dismiss the progress dialog
* **/
protected void onPostExecute(String file_url)
{
pDialog.dismiss();
if (file_url != null)
{
Toast.makeText(Login.this, file_url, Toast.LENGTH_LONG).show();
}
}
}
Basically nothing happens! No Errors or anything??
Any pointers would be greatly appreciated :-)
Cheers

Thanks all, I have decided to dump my own login and use the various social network sdks! I used a combo of EarlofEgo and Deacons answers and this did fix the immediate problem, but I run into a load more!

Do the folloeing changes in ur onClick method of ur Login class
......
@Override
public void onClick(View v)
{
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.login:
new AttemptLogin().execute();
Intent intent = new Intent(this, "Name of the activity u want to go".class);
startActivity(intent);
break;
case R.id.register:
new CreateUser().execute();
Intent intent = new Intent(this, "Name of the activity u want to go".class);
startActivity(intent);
break;

If you want your app to start with Login activity declare it in the manifest :
<activity
android:label="Login"
android:name=".Login" >
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

If you want to start an Activity from another you have to do this in your MainActivity.onCreate():
Intent intent = new Intent(this, Login.class);
startActivity(intent);
I think that's what you are trying to achieve.
