Set Fragment EditText from the parent Activty

Question

I have a ProfileFragment class which contains two setters:

public void setPseudo(String pseudo){
    textPseudo.setText(pseudo);
}
public void setEmail(String email){
    textEmail.setText(email);
}

And in my Activity I would like to call these functions:

user = new ProfileFragment();

if (intent != null) {

    user.setPseudo(intent.getStringExtra(USER_PSEUDO));
    user.setEmail(intent.getStringExtra(USER_EMAIL));
}

It says "can't resolve method...".
Does it mean I can't do this?

Answer 1

Are you sure you don't have a Profile class with setters? Not a Fragment?

Fragments generally don't use setters, they use arguments.

Reason being: If you call setEmail, and then you called to some view setText within the new Fragment, you get a NullPointerException because that TextView was never initialized

Fragment profileFragment = new ProfileFragment();
Bundle args = new Bundle();
if (intent != null) {
    args.putAll(intent.getExtras());
}
profileFragment.setArguments(args);

// Show new Fragment
getSupportFragmentManager()
    .replace(R.id.content, profileFragment)
    .commit();

And inside your Fragment's onCreateView, you can now use this, for example

final Bundle args = getArguments();

String pseudo = "";
if (args != null) {
    pseudo = args.getString(YourActivity.USER_PSEUDO);
}
textPseudo.setText(pseudo);
