我试图从我使用FirebaseRecylerAdapter的方法中检索数据database,如下所示fragment onViewCreated
@Override
public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
FirebaseRecyclerAdapter<AllUsers, AllUsersViewHolder> firebaseRecyclerAdapter;
}
public static class AllUsersViewHolder extends RecyclerView.ViewHolder {
View view;
public AllUsersViewHolder(View itemView) {
super(itemView);
view = itemView;
}
}
当我使用firebaseRecyclerAdapter = new FirebaseRecyclerAdapter它不会给我populateViewHolder方法只是给下面的方法
FirebaseRecyclerAdapter<AllUsers, AllUsersViewHolder> firebaseRecyclerAdapter = new FirebaseRecyclerAdapter<AllUsers, AllUsersViewHolder>() {
@Override
protected void onBindViewHolder(AllUsersViewHolder holder, int position, AllUsers model) {
}
@Override
public AllUsersViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
return null;
}
};
有人可以告诉我为什么会这样吗
