带改装的再循环视图2

Question

我尝试使用Reform2执行recyclerView，但我在代码中执行了：recyclerView适配器构造函数，并且我在此行的MainActivity部分中得到了一个错误-“（flowersList，this）”：我得到了错误：列出匿名Reform2。回调函数

RecyclerViewFlowersAdapter recyclerViewAdapter = new RecyclerViewFlowersAdapter(flowersList, this);

我的代码我的主要活动是：

  try {
        APIService service = ApiClient.getRetrofit().create(APIService.class);
        retrofit2.Call<List<Flower>> call = service.getFlowerData();
        call.enqueue(new Callback<List<Flower>>() {

            @Override
            public void onResponse(retrofit2.Call<List<Flower>> call, Response<List<Flower>> response) {
                List<Flower> flowersList = response.body();
                mLinearLayoutManager = new LinearLayoutManager(MainActivity.this);

                mRecyclerView = findViewById(R.id.recycler_view);
                mRecyclerView.setLayoutManager(mLinearLayoutManager);

                RecyclerViewFlowersAdapter recyclerViewAdapter = new RecyclerViewFlowersAdapter(flowersList, this);
                mRecyclerView.setAdapter(recyclerViewAdapter);
            }

RecycleServiceWFlowerAdapter中的代码是：

public class RecyclerViewFlowersAdapter extends RecyclerView.Adapter<RecyclerViewHolder> {
private List<Flower> mFlowers;
private Context mContext;

public RecyclerViewFlowersAdapter(List<Flower> flowers, Context context) {
    mContext = context;
    mFlowers = flowers;
}


@Override
public RecyclerViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.flower_item_card, null);
    RecyclerViewHolder recyclerViewHolder = new RecyclerViewHolder(view);
    return recyclerViewHolder;
}

@Override
public void onBindViewHolder(RecyclerViewHolder holder, int position) {
 holder.mTextViewTitle.setText(mFlowers.get(position).getName());

    Picasso.with(mContext)
            .load(mFlowers.get(position).getPhoto()).into(holder.mImageViewFlower);

}

@Override
public int getItemCount() {
    return mFlowers.size();
}

}

我在RecycleServiceWholder中的代码是：

public class RecyclerViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {

public TextView mTextViewTitle;
public ImageView mImageViewFlower;


public RecyclerViewHolder(View itemView){
    super(itemView);
    itemView.setOnClickListener(this);

    mTextViewTitle = itemView.findViewById(R.id.title);
    mImageViewFlower = itemView.findViewById(R.id.imageViewFlower);

}

@Override
public void onClick(View v) {

}

}

我尝试做很多事情，但仍然是错误的。

Answer 1

您可能使用了错误的上下文，请尝试使用MainActivity。此而不是此。更改此

RecyclerViewFlowersAdapter recyclerViewAdapter = new RecyclerViewFlowersAdapter(flowersList, this);

到这个

RecyclerViewFlowersAdapter recyclerViewAdapter = new RecyclerViewFlowersAdapter(flowersList, MainActivity.this);
