最佳答案

您已经在使用 FirebaseRecyclerOptions:

  FirebaseRecyclerOptions<Category> options =
new FirebaseRecyclerOptions.Builder<Category>()
.setQuery(MenuViewHolder, Category.class)
.build();

构造函数 FirebaseRecyclerAdapter 采用此处指定的 FirebaseRecyclerOptions 类型的变量:

https://github.com/firebase/FirebaseUI-Android/blob/master/database/src/main/java/com/firebase/ui/database/FirebaseRecyclerAdapter.java#L37

改变这个:

FirebaseRecyclerAdapter adapter = new FirebaseRecyclerAdapter<Category, MenuViewHolder>(Category.class,R.layout.menu_item,MenuViewHolder.class,category) {

进入这个:

FirebaseRecyclerAdapter adapter = new FirebaseRecyclerAdapter<Category, MenuViewHolder>(options) {
