I have a Fragment that calls another Fragment by passing login information to the other. I do this with the following code through the Bundle. Follow the code :
ImageView editarBt = (ImageView) view.findViewById(R.id.editar);
editarBt.setOnClickListener(new Button.OnClickListener(){
@Override
public void onClick(View view) {
Bundle data = new Bundle();
data.putString("nome", listaUser.get(auxPosition).getNome());
data.putString("email", listaUser.get(auxPosition).getEmail());
data.putString("np", listaUser.get(auxPosition).getNp());
data.putString("tipoFunc", listaUser.get(auxPosition).getTipoFunc());
data.putInt("id", listaUser.get(auxPosition).getId());
Fragment fragment = new adicionar_usuario();
fragment.setArguments(data);
FragmentManager manager = getFragmentManager();
manager.beginTransaction().replace(R.id.content,fragment,fragment.getTag()).addToBackStack(null).commit();
}
});
The problem is I’m having trouble capturing that data in the other fragment. I managed to do this with Intent when I have activitys, with the following code:
Intent intent = getActivity().getIntent();
if(intent != null){
Bundle bundle = getArguments();
if(bundle != null){
int id = bundle.getInt("id");
String nome = bundle.getString("nome");
String email = bundle.getString("email");
String tipoFunc = bundle.getString("tipoFunc");
String np = bundle.getString("np");
usuario.setId(id);
usuario.setNome(nome);
usuario.setEmail(email);
usuario.setTipoFunc(tipoFunc);
usuario.setNp(np);
nomeEt.setText(usuario.getNome());
emailEt.setText(usuario.getEmail());
npEt.setText(usuario.getNp());
tipoFuncSp.toString();
senhaEt.setVisibility(View.GONE);
salvarBt.setVisibility(View.GONE);
editarUserBt.setVisibility(View.VISIBLE);
}
}
How to transform this code to a Fragment? Making the user field load with user information by clicking the edit button.
You have the following error:

@acklay I edited as you informed me, but is giving error. I edited the question.

Debug the expensive code. Check if Intent is really giving null fierent, otherwise it will not enter within the condition
if(intent != null)– viana
Intent is equal to null
– Lucas Charles
@Lucascharles so was not entering the condition. = D hehehe
– viana
Because it’s haha now I’m trying to see pq. When I’m swallowing my information is correct, but when I pass it, it goes like null to the other fragment.
Fragment fragment = new adicionar_usuario();
 fragment.setArguments(data);

 FragmentManager manager = getFragmentManager();
 manager.beginTransaction().replace(R.id.content,fragment,fragment.getTag()).addToBackStack(null).commit();– Lucas Charles
@Lucascharles Which Intent? What do you get with
getArguments()is a Bundle. On the other hand the error posted in the question refers to the fact that an Edittext is null and not the Bundle. Edit the question and enter the method codeonCreateView().– ramaral
@acklay Thank you so much!

@Did Lucascharles work right?! Need anything else, a touch and/or ask a question. The people here in the O.R.Most of the time like to help.
