Button click does nothing in Action Bar Tabs in Android

  • 772

I'm working on a project with Action Bar Tabs in Android. I have managed to create my fragments and achieve the desired interaction, but I have a problem. In one of those fragments I have a button, but clicking it does nothing.

This is in the code I use to call the fragment from the MainActivity:

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View rootView=null;
        switch (getArguments().getInt(ARG_SECTION_NUMBER)){
            case 1:
                rootView = inflater.inflate(R.layout.fragment_frm_dispositivos, container, false);
                //return rootView;
            break;
            case 2:
                rootView = inflater.inflate(R.layout.fragment_frm_transaccion, container, false);
                //return rootView;
            break;
            case 3:
                rootView = inflater.inflate(R.layout.fragment_frm_cajero, container, false);
                //return rootView;
            break;
        }
        return rootView;
    }
}

and this is what i do in the fragment

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View view =inflater.inflate(R.layout.fragment_frm_cajero, container, false);
    btnGuardar=(Button)view.findViewById(R.id.btnGuardarCajero);
    btnGuardar.setOnClickListener(this);
    return view;
}
 @Override
public void onClick(View v) {
        Toast.makeText(getContext(),"no sirve",Toast.LENGTH_SHORT).show();

}

    The problem is that you are not loading the you are fragmentsimply doing a inflateview on MainActivyit, you only have a view loaded on the screen, not the fragment, if what you want is to change the fragmentfrom MainActivityyou must do a FragmentTransaction :

    MainActivity:

    public View onCreate(Bundle savedInstanceState) {
           Fragment newFragment = null;
           FragmentTransaction transaction = getFragmentManager().beginTransaction();

            switch (getArguments().getInt(ARG_SECTION_NUMBER)){
                case 1:
                  newFragment = New FragmentDispositivos();
                break;
                case 2:
                  newFragment = New FragmentTransaccion();
                break;
                case 3:
                  newFragment = New FragmentCajero();
                break;
            }
            // Debes pasar el contenedor donde tienes el fragment y lo 
            // reemplaza por el nuevo fragment
             transaction.replace(R.id.fragment_container, newFragment);
             transaction.addToBackStack(null);

           // Commit de la transaction
           transaction.commit();
        }
    }
