I am creating a screen with 3 buttons in which each button clicked will need to be redirected to a different site. I implemented this code, there is no error, I can even click the button, only when the page is loaded there is an error in the application and it closes alone. What I’m doing wrong in this way? erro

android

  • What mistake does it make? Post the log of errors.

  • If by clicking the button the page opens then the error is not on the button.

  • Another mistake I realized, is that even without pressing the button he enter the links, one behind the other. It’s as if these conditions had not been worth

  • kkkk Now that I stopped to look no click function there

  • All this is executed when Oncreateview() is started.

  • I’ll show you how to do a function like that.

  • Blz Bruno, I’m on hold

This code you posted does not have a click function, it is running all this when the OnCreateView() is started. Try to do so:

In your class, right after the extends Cronograma, add implements View.OnClickListener.

And in the OnCreateView() do this:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    super.onCreateView(inflater, container, savedInstanceState);

    View view = inflater.inflate(R.layout.solicitacoes, container, false);
    Button button1 = view.findViewById(R.id.id_do_button1);
    Button button2 = view.findViewById(R.id.id_do_button2);
    Button button3 = view.findViewById(R.id.id_do_button3);
    button1.setOnClickListener(this);
    button2.setOnClickListener(this);
    button3.setOnClickListener(this);

  return view;
 }

So to finish just create (the correct term I think is to implement) the function of OnClick:
Obs: I gave a simplified in its function using switch instead of if, taking into account that you just want to catch the event of clicking the buttons on this classe:

@Override
public void onClick(View v) {
   String url = "";
   switch (v.getId()) {
     case R.id.button:
       url = "sua url aqui";
       break;
     case R.id.button:
       url = "sua url aqui";
       break;
     default: // padrão, seria igual o else aqui
       url = "url padrão aqui";
       break;

     Intent it = new Intent(Intent.ACTION_VIEW, Uri.parse(url))...
     startActivity(it);
   }
}

  • Bruno so mais uma duvida, nessa linha: View view = inflater.inflate(R.layout.solicitacoes, container, false);
 Button seuButton = view.findViewById(R.id.id_do_seu_button);
 seuButton.setOnClickListener(this) eu coloco o id de cada botaow(no meu caso 3 botoes)?

  • Perfetio Bruno, mto obgdo. the application is running smoothly.
