Question

我正在显示评论列表。我能够从服务器获取列表。但它不会显示在RecyclerView中。在logcat中，它显示如下：

03-14 14:34:32.360    6545-6545/com.couragedigital.petapp E/RecyclerView﹕ No adapter attached; skipping layout
03-14 14:34:32.391    6545-6545/com.couragedigital.petapp E/RecyclerView﹕ No adapter attached; skipping layout
03-14 14:34:32.425    6545-6545/com.couragedigital.petapp E/RecyclerView﹕ No adapter attached; skipping layout
03-14 14:34:32.433    6545-6545/com.couragedigital.petapp E/RecyclerView﹕ No adapter attached; skipping layout
03-14 14:35:00.626    6545-6545/com.couragedigital.petapp E/RecyclerView﹕ No adapter attached; skipping layout

我的Recyclerview

recyclerView = (RecyclerView) findViewById(R.id.clinicRateNReview);
    recyclerView.setHasFixedSize(true);
    //recyclerView.setNestedScrollingEnabled(false);
    linearLayoutManager = new LinearLayoutManager(this);
    recyclerView.setLayoutManager(linearLayoutManager);

    reviewAdapter = new ClinicReviewsListAdapter(clinicReviewsListItemsArrayList);
recyclerView.setAdapter(reviewAdapter);

之后我从服务器获取列表并将其添加到列表并使用reviewAdapter.notifyDataSetChanged()通知适配器。

以下是我的Clinic Review适配器代码

public class ClinicReviewsListAdapter extends RecyclerView.Adapter<ClinicReviewsListAdapter.ViewHolder>{

List<ClinicReviewsListItems> clinicReviewsListsItem;
View v;
ViewHolder viewHolder;

public ClinicReviewsListAdapter(List<ClinicReviewsListItems> clinicReviewsListArrayList) {
    this.clinicReviewsListsItem = clinicReviewsListArrayList;
}

@Override
public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
    v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.clinic_review_list_items, viewGroup, false);
    viewHolder = new ViewHolder(v);
    return viewHolder;
}

@Override
public void onBindViewHolder(ViewHolder viewHolder, int i) {
    ClinicReviewsListItems clinicReviewsListItems = clinicReviewsListsItem.get(i);
    viewHolder.bindClinicReviewsList(clinicReviewsListItems);
}

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

public class ViewHolder extends RecyclerView.ViewHolder {

    public TextView clinicReviews;
    public TextView email;
    public View clinicListDividerLine;
    public int userRatings;
    LinearLayout layout;

    public ViewHolder(View itemView) {
        super(itemView);

        layout = (LinearLayout) itemView.findViewById(R.id.ratingNos);
        clinicReviews = (TextView) itemView.findViewById(R.id.reviews);
        email = (TextView) itemView.findViewById(R.id.usersName);
        clinicListDividerLine = itemView.findViewById(R.id.viewdividerline);
    }

    public void bindClinicReviewsList(ClinicReviewsListItems clinicReviewsList) {
        userRatings=Integer.parseInt(clinicReviewsList.getClinicRatings());

        for(int i=0;i<userRatings;i++)
        {
            ImageView image = new ImageView(v.getContext());
            image.setLayoutParams(new android.view.ViewGroup.LayoutParams(80,60));
            image.setMaxHeight(20);
            image.setMaxWidth(20);
            image.setId(i);
            image.setImageResource(R.drawable.ratingstar_yellow);
            // Adds the view to the layout
            image.setPadding(3, 3, 3, 3);
            layout.addView(image);
        }
        clinicReviews.setText(clinicReviewsList.getClinicReviews());
        email.setText(clinicReviewsList.getEmail());
        clinicListDividerLine.setBackgroundResource(R.color.list_internal_divider);
    }
}

}

Answer 1

添加：

  recyclerView.setAdapter(reviewAdapter);

在notifydatasetchanged之前或在适配器创建之后。

E / RecyclerView没有附加addapter，跳过布局
