Error while editing through SQLITE

Question

I’m trying to edit information that’s saved in the SQLITE gang. I’m working with fragments. But I’m making the following mistake:

FATAL EXCEPTION: main

I have a listview with all contacts, and in each contact I have an icon to edit and delete. The edit would be as follows:`

ImageView editarBt = (ImageView) view.findViewById(R.id.editar);
            editarBt.setOnClickListener(new Button.OnClickListener(){
                @Override
                public void onClick(View view) {
                    Intent intent = new Intent(getActivity(), adicionar_usuario.class);
                    intent.putExtra("nome", listaUser.get(auxPosition).getNome());
                    intent.putExtra("email", listaUser.get(auxPosition).getEmail());
                    intent.putExtra("np", listaUser.get(auxPosition).getNp());
                    intent.putExtra("tipoFunc", listaUser.get(auxPosition).getTipoFunc());
                    intent.putExtra("id", listaUser.get(auxPosition).getId());
                   getActivity().startActivity(intent);
                }
            });

When I click edit error happens.

I tried to change these codes:`

 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);




                }
            });
`

Can anyone tell me the reason for this mistake?

Answer 1

Lucas,

When you will put a Fragment in some Activity, you use the following code:

FragmentManager fragmentManager = getSupportFragmentManager();
        fragmentManager.beginTransaction()
                .replace(R.id.container, adicionar_usuario, "adicionar usuário")
                .commit();

And in Layout, you should have a Framelayout with id container, example:

<FrameLayout
  android:id="@+id/container"
  android:layout_width="match_parent"
  android:layout_height="match_parent" />

You must have done it already to declare this current Fragment that you put the code there.

Any doubt screams there.
