为 RecyclerView 中的其他项目重复图片

Question

首先，请原谅我，我的英语不好。

我有一个RecyclerView，里面有9个item，但是从第四个item到下一个，其他item重复了前4个item的图片！但其他字段对于 RecyclerView 中的所有项目，都已正确完成。

如何解决问题？

这是我的代码：

我的模特：

public class LocationsListModel {

final String DRAWABLE = "drawable/";
private String name,imageUrl, review, price;

public LocationsListModel(String name, String review, String price, String imageUrl) {
    this.name = name;
    this.review = review;
    this.price = price;
    this.imageUrl = imageUrl;
}

public String getName() {
    return name;
}
public String getReview() {
    return review;
}
public String getPrice() {
    return price;
}
public String getImageUrl() {
    return DRAWABLE + imageUrl;
}}

我的适配器：

public class LocationsListAdapter extends RecyclerView.Adapter<LocationsListAdapter.LocationsListView> {

private static ArrayList<LocationsListModel> locationList;
private Context context;
private ImageView locationImage;


public void setItems(ArrayList<LocationsListModel> items) {
    this.locationList = items;
}


public class LocationsListView extends RecyclerView.ViewHolder {

    public CardView cardView;
    public TextView locationName;
    public TextView review;
    public TextView locationPrice;


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

        cardView = itemView.findViewById(R.id.cardView);

        locationName = itemView.findViewById(R.id.location_name);
        review = itemView.findViewById(R.id.review);
        locationPrice = itemView.findViewById(R.id.price);
        locationImage = itemView.findViewById(R.id.imageView2);
    }
}

@Override
public LocationsListAdapter.LocationsListView onCreateViewHolder(ViewGroup parent, int viewType) {

    View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.locations_list_item, parent, false);

    context = parent.getContext();

    return new LocationsListView(view);
}

@Override
public void onBindViewHolder(LocationsListAdapter.LocationsListView holder, int position) {
    final LocationsListModel locationsListModel = locationList.get(position);


    String uri = locationsListModel.getImageUrl();
    int resource = locationImage.getResources().getIdentifier(uri, null, locationImage.getContext().getPackageName());
    locationImage.setImageResource(resource);

    holder.locationName.setText(locationsListModel.getName());
    holder.review.setText(locationsListModel.getReview());
    holder.locationPrice.setText(locationsListModel.getPrice());

}

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

我的片段：

public class LocationsListFragment extends Fragment {

private final LocationsListAdapter locationsListAdapter = new LocationsListAdapter();
private RecyclerView locationsList;
SimpleRatingBar ratingBar;
ArrayList<LocationsListModel> locationsListModels = new ArrayList<>();


public LocationsListFragment() {
    // Required empty public constructor
}

// TODO: Rename and change types and number of parameters
public static LocationsListFragment newInstance() {
    LocationsListFragment fragment = new LocationsListFragment();
    return fragment;
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    final View view = inflater.inflate(R.layout.fragment_locations_list, container, false);

    ratingBar = view.findViewById(R.id.ratingBar);
    locationsList = view.findViewById(R.id.locations_lis);

    setRecyclerViewItems();

    return view;
}

private void setRecyclerViewItems() {

    SnapHelper snapHelper = new LinearSnapHelper();
    snapHelper.attachToRecyclerView(locationsList);

    locationsList.setLayoutManager(new LinearLayoutManager(getContext(),
            LinearLayoutManager.HORIZONTAL, true));

    locationsList.setAdapter(locationsListAdapter);


    locationsListModels.add(new LocationsListModel("Hotel 1","120 reviews","200$", "pic1"));
    locationsListModels.add(new LocationsListModel("Hotel 2","102 reviews","120$", "pic2"));
    locationsListModels.add(new LocationsListModel("Hotel 3","84 reviews","240$", "pic3"));
    locationsListModels.add(new LocationsListModel("Hotel 4","113 reviews","220$", "pic4"));
    locationsListModels.add(new LocationsListModel("Hotel 5","52 reviews","140$", "pic5"));
    locationsListModels.add(new LocationsListModel("Hotel 6","57 reviews","190$", "pic6"));
    locationsListModels.add(new LocationsListModel("Hotel 7","230 reviews","300$", "pic7"));
    locationsListModels.add(new LocationsListModel("Hotel 8","131 reviews","90$", "pic8"));
    locationsListModels.add(new LocationsListModel("Hotel 9","32 reviews","110$", "pic9"));

    locationsListAdapter.setItems(locationsListModels);
    locationsList.setHasFixedSize(true);

}}

Answer 1

在Gradle中：

compile 'com.github.bumptech.glide:glide:3.5.2'

适配器：

Glide.with(context).load(imageurl).transform(new RoundImageTransform(context)).skipMemoryCache(true).into(ImageView);

注意：删除 RoundImageTransform -- 它是为了使图像视图成为圆形

Answer 2

你应该使用整数类型的图像 -> R.drawable.p2

和您的 app/build.gradle 添加：

compile 'com.github.bumptech.glide:glide:4.3.1'
annotationProcessor 'com.github.bumptech.glide:compiler:4.3.1'

您的模特：

 public class LocationsListModel {
    public String name, review, price;
    public int imageResource;

    public LocationsListModel(String name, String review, String price, int imageResource) {
        this.name = name;
        this.review = review;
        this.price = price;
        this.imageResource = imageResource;
    }
}

您的适配器：

@Override
    public void onBindViewHolder(LocationsListAdapter.LocationsListView holder, int position) {

        LocationsListModel locationsListModel = locationList.get(position);

        GlideApp.with(context).load(locationsListModel.imageResource)
                              .into(holder.imageView);

        holder.locationName.setText(locationsListModel.name);
        holder.review.setText(locationsListModel.review);
        holder.locationPrice.setText(locationsListModel.price);

    }
}

你的片段

locationsListModels.add(new LocationsListModel("Hotel 1","120 reviews","200$", R.drawable.pic1));
