Answer 1

Update your adapter constructor to accept the Fragment as a parameter.

Something like :

public CustomAdapter(Context context, int id, HomeFragment fragment) {
    this.fragment = fragment;
}

then you call methods using the fragment variable.

fragment.doSomething();

and in this method you can refresh the list using notifyDataSetChanged();

Answer 2

Basically your list view is connected with adapter. You need to notify this adapter to redraw the list view. Can you give more information where exactly your button click listener code is (in which class). If it is inside your adapter class (like I suppose) you can do something like this in your click listener code (some where inside the method public void onClick(View arg0) ) :

YourAdapterClassName.this.notifyDataSetChanged();

Answer 3

Simple call notifyDataSetChanged(); when you click in button for refresh your ListView

buttonHeart.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View arg0) {
         ...
         notifyDataSetChanged();
    }
});
