Method onAttach Android

Question

Guys, I’m having trouble using the onattach. I have a view that is set Visible when a button is triggered. I would like this View to disappear at the end of an operation of a Fragment. Look at the Code that will make more sense.

Na Activity:

    private View layoutProgress;

    protected void onCreate(Bundle savedInstanceState){

    layoutProgress = findViewById(R.id.layout_progress);

    layoutProgress.setVisibility(View.GONE);
    }

When the Button is set:

    fragment.getInstance().printScreen();(Função de Tirar foto no fragment)
    layoutProgress.setVisibility(View.VISIBLE);

No Fragment:

Runs the necessary and would like the layoutProgress to disappear.

How do you do that? Sorry about the editing, I’m still learning how to format better.

Answer 1

I found a way, I’ll post it if anyone needs it

after running the code in Fragment put this code:

    Activity act = getActivity();
    if (act == null) return;
    View layoutProgress = findViewById(R.id.layout_progress);
