I have two snippets attached to my activity.
My question is, how do I initialize an element that is in another fragment?
In a fragment, to access the activity I use the code
Textview tv = getActivity().findViewById(R.id.tv);
This works, but to start one that is linked to the fragment and not to activity ???
Use the Activity as an intermediary between fragments (fragmentA and fragmentB).
Declare a method in fragmentA, the one whose TextView wants to change:
public void setText(String text){
textView.setText(text);
}
Declare a method in the activity that calls fragmentA:
public void setFragmentATextView(String text){
fragmentA.setText(text);
}
In fragmentB call the activity method:
getActivity().setFragmentATextView("qualquer coisa");
Note: The call to Activity methods should be done through a interface and not by getActivity().nomeMetodo() .
