Calling a method in one fragment from another

Question

I\'ve been trying for a while already (as well, searching in here) for something to help me to refresh listView in my MainFragment, when a button is pressed in other fragmen

Answer 1

In MainFragment class you can do the following code:

private static MainFragment instance = null;

@Override  
public void onCreate(@Nullable Bundle savedInstanceState) {  
    super.onCreate(savedInstanceState);  
    instance = this;  
}

public static MainFragment getInstance() {  
    return instance;  
} 

And in SocialMedia class you can call the method as follows:

MainFragment.getInstance().otherList();
