android - 如何在 Firebase 回收器适配器中实现 recyclerview ItemClickListener()？

Question

我在 YouTube 上学习了本教程.
我设法搜索了数据，但现在我想在回收站 View 中打开所选数据的详细信息页面。我如何完成它？我应该在哪一部分为recyclerview 实现onClickListener？我试图将 onClickListener 放入方法 OnBindViewHolder 和 SetDetails 中， Intent 将额外的...放入方法 OnBindViewHolder 和 SetDetails 中，但它们都无法识别我的上下文。

这是我当前的代码:

    private void firebaseIngredientSearch(String searchIngredient) {

    Toast.makeText(SearchActivity.this, "Started Search", Toast.LENGTH_LONG).show();

    Query firebaseSearchQuery = databaseReference.orderByChild("ingName").startAt(searchIngredient).endAt(searchIngredient + "\uf8ff");

    FirebaseRecyclerOptions<Ingredients> firebaseRecyclerOptions = new FirebaseRecyclerOptions.Builder<Ingredients>()
            .setQuery(firebaseSearchQuery, Ingredients.class)
            .build();

    FirebaseRecyclerAdapter<Ingredients, SearchActivity.IngredientsViewHolder> firebaseRecyclerAdapter = new
            FirebaseRecyclerAdapter<Ingredients, SearchActivity.IngredientsViewHolder>(firebaseRecyclerOptions) {

                @Override
                protected void onBindViewHolder(@NonNull IngredientsViewHolder holder, int position, @NonNull final Ingredients model) {


                    holder.setDetails(model.getIngName(), model.getIngStatus(),model.getIngCategory(),model.getIngCategory());

                holder.view.setOnClickListener(new View.OnClickListener() {
                        @Override
                        public void onClick(View view) {
                            Intent goDetail = new Intent(, IngredientSearchDetailsActivity.class);
                            goDetail.putExtra("ingName", model.getIngName());
                            goDetail.putExtra("ingStatus", model.getIngStatus());
                            goDetail.putExtra("ingCategory", model.getIngCategory());
                            goDetail.putExtra("ingDescription", model.getIngDescription());

                            mActivity.startActivity(goDetail);
                        }
                    });



                }

                @NonNull
                @Override
                public IngredientsViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {

                    View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.layout_searched_ingredient, parent, false);
                    return new IngredientsViewHolder(view);
                }
            };

    firebaseRecyclerAdapter.startListening();
    rvSearchResult.setAdapter(firebaseRecyclerAdapter);

}

        i_Name.setText(ingName);
        i_Status.setText(ingStatus);       
        i_Category.setText(ingCategory);
        i_Description.setText(ingDescription);

    }

}

用户 holder.view.setOnClickListener 启动 OnClickListener 并使用 holder.view.getContext() 而不是 mActivity

holder.view.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        Intent goDetail = new Intent(, IngredientSearchDetailsActivity.class);
        goDetail.putExtra("ingName", model.getIngName());
        goDetail.putExtra("ingStatus", model.getIngStatus());
        goDetail.putExtra("ingCategory", model.getIngCategory());
        goDetail.putExtra("ingDescription", model.getIngDescription());

        holder.view.getContext().startActivity(goDetail);
    }
});
