Android : How do I update my textView in a Fragment

Question

I am trying to use fragments to build my first proper Android App. I have a main xml. which consists of two vertical fragments, the top fragments consists of just two TextVi

Answer 1

I am using this code from my activity to update a textview added in xml tag. The textview are class level objects. Heres some code:

Heres the fragment code just showing the class level variable.

public class RegisterFragment extends Fragment implements OnClickListener {

TextView textViewDOB, textViewLanguage;

public RegisterFragment() {
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
//eluded methods here
}
}

Now the activity from where I update my fragment:

public class RegisterActivity extends FragmentActivity {
Button buttonEnter;
RegisterFragment fragmentRegister;

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_register);
    buttonEnter = (Button) findViewById(R.id.buttonEnter);
    fragmentRegister = (RegisterFragment) getSupportFragmentManager()
            .findFragmentById(R.id.fragmentRegister);
}

@Override
protected void onStart() {
    // TODO Auto-generated method stub
    super.onStart();
    buttonEnter.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Log.d("dontknowitwillowrk", fragmentRegister.textViewLanguage
                    .getText().toString());
            fragmentRegister.textViewLanguage.setText("hello mister how do you do");


        }
    });
}
}

Note: not sure if this is a good way.
