我需要在服务器上拍摄的recyclerview张照片中显示。
从server正确提取图片，但glide没有向我显示图片，我不知道原因。
我告诉你我的代码：
VIDEO：
public class Video {
public String pic;
public String sottotitolo;
public String titolo;
public String data;
public Video() {
}
public Video(String pic,String sottotitolo,String titolo,String data){
this.pic = pic;
this.sottotitolo=sottotitolo;
this.titolo=titolo;
this.data=data;
}
public String getPic() {
return pic;
}
public void setPic(String pic) {
this.pic = pic;
}
public String getSottotitolo() {
return sottotitolo;
}
public void setSottotitolo(String sottotitolo) {
this.sottotitolo = sottotitolo;
}
public String getTitolo() {
return titolo;
}
public void setTitolo(String titolo) {
this.titolo = titolo;
}
public String getData() {
return data;
}
public void setData(String data) {
this.data = data;
}
}
ADAPTER：
public class VideoAdapter extends RecyclerView.Adapter<VideoAdapter.VideoHolder> {
private ArrayList<Video> mData;
private ArrayList<Video> mData2;
private Activity mACtivity;
public VideoAdapter(ArrayList<Video> data,ArrayList<Video> data2,Activity activity) {
this.mData = data;
this.mData2 = data2;
this.mACtivity = activity;
}
@Override
public VideoHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.anteprima_list_item, parent, false);
return new VideoHolder(view);
}
@Override
public void onBindViewHolder(VideoHolder holder, int position) {
Video video = mData.get(position);
Video video2 = mData2.get(position);
holder.setTitolo(video.getTitolo());
holder.setSottoTitolo(video.getSottotitolo());
holder.setData(video.getData());
holder.setData(video.getData());
/* holder.setAddress(restaurant.getAddress());
holder.setCost("Average cost for 2: " + restaurant.getCurrency() + restaurant.getCost());
holder.setRating(restaurant.getRating());*/
Glide.with(mACtivity)
.load(video2.getPic())
.into(holder.restaurantImageView);
}
@Override
public int getItemCount() {
if (mData == null)
return 0;
return mData.size();
}
public class VideoHolder extends RecyclerView.ViewHolder {
ImageView restaurantImageView;
TextView restaurantNameTextView;
TextView restaurantAddressTextView;
TextView restaurantRatingTextView;
TextView costTextView;
TextView distanceTextView;
public VideoHolder(View itemView) {
super(itemView);
restaurantImageView = (ImageView) itemView.findViewById(R.id.imageview_restaurant);
restaurantNameTextView = (TextView) itemView.findViewById(R.id.textview_restaurant_name);
restaurantAddressTextView = (TextView) itemView.findViewById(R.id.restaurant_address_textview);
distanceTextView = (TextView) itemView.findViewById(R.id.restaurant_distance_textview);
/* costTextView = (TextView) itemView.findViewById(R.id.cost_for_two_textview);
restaurantRatingTextView = (TextView) itemView.findViewById(R.id.rating);*/
}
public void setTitolo(String titolo) {
restaurantNameTextView.setText(titolo);
}
public void setSottoTitolo(String sottotitolo) {
restaurantAddressTextView.setText(sottotitolo);
}
public void setData(String data) {
distanceTextView.setText(data);
}
/* public void setPic(String pic) {
distanceTextView.setText(pic);
}
public void setCost(String cost) {
costTextView.setText(cost);
}
public void setDistance(String distance) {
distanceTextView.setText(distance);
}*/
}
}
