Unable to pass 1st activity's textview value t

Question

I am trying to pass textview value between different activities, here is my code that i've tried:

LoginActivity.java

    public class LoginActivity extends Activity {

Button btnLogin;
private EditText inputEmail;
private EditText inputPassword;
private ProgressDialog pDialog;
private SessionManager session;
private SQLiteHandler db;


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

    inputEmail = (EditText) findViewById(R.id.email);
    inputPassword = (EditText) findViewById(R.id.password);
    btnLogin = (Button) findViewById(R.id.btnLogin);

    // Progress dialog
    pDialog = new ProgressDialog(this);
    pDialog.setCancelable(false);

    // SQLite database handler
    db = new SQLiteHandler(getApplicationContext());

    // Session manager
    session = new SessionManager(getApplicationContext());



    // Check if user is already logged in or not
    if (session.isLoggedIn()) {
        // User is already logged in. Take him to main activity
        Intent intent = new Intent(LoginActivity.this, SliderMenu.class);
        startActivity(intent);
        finish();
    }

    // Login button Click Event
    btnLogin.setOnClickListener(new View.OnClickListener() {

        public void onClick(View view) {
            String email = inputEmail.getText().toString().trim();
            String password = inputPassword.getText().toString().trim();

            // Check for empty data in the form
            if (!email.isEmpty() && !password.isEmpty()) {
                // login user
                checkLogin(email, password);
                // Prompt user to enter credentials
                Toast.makeText(getApplicationContext(), "Please enter the credentials!", Toast.LENGTH_LONG).show();
            }
        }

    });

}

        setListAdapter(adapter);
    }
}
 }

I dont know whats wrong with code but log is showing that in LoginActivity String a is getting textview value, but StudentActivity String a is not getting value from previous activity.. Any help would be truely appreciated...

Updated: Finally i just change my code for passing value from getIntent() method to shared preferences, now its passing data like a charm :) Here is the link..

Answer 1

Activity 1:

 Intent ii = new Intent(this, ShareOnFacebook.class);
Bundle bundle=new Bundle();
bundle.putString("message", facebookMessage);
startActivity(ii.putExtras(bundle))

Activity2:
String facebookMessage = getIntent().getStringExtra("message"); 
TextView txtView = (TextView) findViewById(R.id.your_resource_textview);    
txtView.setText(message);

Answer 2

you are passing bundle in the intent and retrieving intent extra. Either you pass bundle and retrieve bundle or pass intent extra and retrieve the same. In you code while calling the StudentActivity try below code. i.e

  Intent ii = new Intent(LoginActivity.this, StudentActivity.class);
  ii.putExtra("level", a);         
  startActivity(ii);

Answer 3

 String a = getIntent().getExtras().getString("level");
 textView.setText(String.valueOf(a));

Answer 4

Try using getExtras()....

    Bundle i = getIntent().getExtras();
    String a = i.getStringExtra("level");
    Log.d("TAG1", String.valueOf(a));
    textView.setText(String.valueOf(a));
