Question

i am very new to android.
i m trying to develop a login form for practise , and i m unable to pass and display 2 values
to another activity

Intent intent = new Intent(this, Success.class);
        EditText edituser = (EditText) findViewById(R.id.userinput);
        EditText editpass= (EditText) findViewById(R.id.passinput);
        String username = edituser.getText().toString();
        String password = editpass.getText().toString();

        intent.putExtra(EXTRA_USER, username);
        intent.putExtra(EXTRA_PASSWORD, password);
        startActivity(intent);

and target activity is

 Intent intent = getIntent();
    String username = intent.getStringExtra(MainActivity.EXTRA_USER);
    String password = intent.getStringExtra(MainActivity.EXTRA_PASSWORD);

    // Create the text view
    TextView userView = new TextView(this);
    TextView passView = new TextView(this);
    userView.setTextSize(40);
    userView.setText(username);

    passView.setTextSize(40);
    passView.setText(password);

    // Set the text view as the activity layout
    setContentView(userView);
    setContentView(passView);

Answer 1

Your problem is that when you call setContentView() the second time, you remove the older view from the screen.

Try adding your Views to a ViewGroup like a LinearLayout and then adding that to the screen instead of individual Views.

Something like:

LinearLayout ll = new LinearLayout(this);
ll.addView(userView);
ll.addView(passView);
setContentView(ll);
