我已阅读google documentation，我已从附近的搜索请求中获取了photoreference密钥。当我们运行google place照片API的网址时，我们会获得图片。由于我只有一个URL，如何在图像视图上显示该图像URL。
我的模态课程：
public class PlacesResponse {
public class Root implements Serializable {
@SerializedName("results")
public ArrayList<CustomA> customA = new ArrayList<>();
@SerializedName("status")
public String status;
}
public class CustomA implements Serializable {
@SerializedName("geometry")
public Geometry geometry;
@SerializedName("vicinity")
public String vicinity;
@SerializedName("name")
public String name;
@SerializedName("photos")
public ArrayList<Photos> photos = new ArrayList<>();
@SerializedName("place_id")
public String place_id;
}
public class Photos implements Serializable{
@SerializedName("photo_reference")
public String photo_reference;
}
public class Geometry implements Serializable{
@SerializedName("location")
public LocationA locationA;
}
public class LocationA implements Serializable {
@SerializedName("lat")
public String lat;
@SerializedName("lng")
public String lng;
}
}
附近地点搜索请求代码
private void fetchStores(String placeType) {
Call<PlacesResponse.Root> call = apiService.doPlaces(latLngString,radius,placeType, ApiClient.GOOGLE_PLACE_API_KEY);
call.enqueue(new Callback<Root>() {
@Override
public void onResponse(Call<PlacesResponse.Root> call, Response<PlacesResponse.Root> response) {
PlacesResponse.Root root = (Root) response.body();
if (response.isSuccessful()) {
if (root.status.equals("OK")) {
results = root.customA;
storeModels = new ArrayList<>();
distnaceModels = new ArrayList<>();
Log.i(TAG,"fetch stores");
for (int i = 0; i < results.size(); i++) {
PlacesResponse.CustomA info = (CustomA) results.get(i);
String place_id = results.get(i).place_id;
// this gives me the photo reference for the request
String photo_reference = results.get(i).photos.get(0).photo_reference;
fetchDistance(info);
// fetchPlace_details(place_id);
}
} else {
Toast.makeText(getApplicationContext(), "No matches found near you", Toast.LENGTH_SHORT).show();
}
} else if (response.code() != 200) {
Toast.makeText(getApplicationContext(), "Error " + response.code() + " found.", Toast.LENGTH_SHORT).show();
}
}
@Override
public void onFailure(Call call, Throwable t) {
// Log error here since request failed
call.cancel();
}
});
}
适配器类
public class Rv_adapter extends RecyclerView.Adapter<MyViewHolder> {
private ArrayList<PlacesResponse.CustomA> stLstStores;
private ArrayList<Modal> storeModels;
private static final int TYPE_HEAD=0;
private static final int TYPE_LIST=1;
public Rv_adapter(ArrayList<PlacesResponse.CustomA> stLstStores, ArrayList<Modal> storeModels) {
this.stLstStores = stLstStores ;
this.storeModels = storeModels;
}
@Override
public MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
if(viewType==TYPE_LIST) {
View itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.recyclerview_listitem, parent, false);
return new MyViewHolder(itemView,viewType);
}
else if(viewType==TYPE_HEAD)
{
View itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.recyclerview_header, parent, false);
return new MyViewHolder(itemView,viewType);
}
return null;
}
@Override
public int getItemViewType(int position) {
if(position==0){
return TYPE_HEAD;}
else{
return TYPE_LIST;
}
}
@Override
public void onBindViewHolder(MyViewHolder holder, int position)
{
Log.i("adapter_posn",holder.getAdapterPosition()+"");
Log.i("view type",holder.view_type+"");
if(holder.view_type == TYPE_LIST) {
holder.res_name.setText(stLstStores.get(holder.getAdapterPosition()-1).name);
// holder.res_address.setText(storeModels.get(holder.getAdapterPosition()-1).address);
// holder.res_phone.setText(storeModels.get(holder.getAdapterPosition()-1).phone_no);
// holder.res_rating.setText(String.valueOf(storeModels.get(holder.getAdapterPosition()-1).rating));
// holder.res_distance.setText(String.valueOf(storeModels.get(holder.getAdapterPosition()-1).distance));
}
else if (holder.view_type == TYPE_HEAD)
{
holder.current_location.setText(String.valueOf(storeModels.get(holder.getAdapterPosition()).current_location));
}
}
@Override
public int getItemCount() {
return stLstStores.size()+1;
}
public class MyViewHolder extends RecyclerView.ViewHolder {
TextView res_name;
TextView res_rating;
TextView res_address;
TextView res_phone;
TextView res_distance;
TextView current_location;
ImageView res_image;
int view_type;
public MyViewHolder(View itemView,int viewType) {
super(itemView);
if(viewType == TYPE_LIST) {
view_type=1;
this.res_name = (TextView) itemView.findViewById(R.id.name);
this.res_rating = (TextView) itemView.findViewById(R.id.rating);
this.res_address = (TextView) itemView.findViewById(R.id.address);
this.res_phone = (TextView) itemView.findViewById(R.id.phone);
this.res_distance = (TextView) itemView.findViewById(R.id.distance);
this.res_image = (ImageView) itemView.findViewById(R.id.res_image);
}
else if(viewType == TYPE_HEAD){
view_type = 0;
this.current_location = (TextView) itemView.findViewById(R.id.location_tv);
}
}
}
}
请注意我会通过放置照片参考，API密钥和宽度来形成图片的网址，我想知道如何在图片视图中以图片的形式显示此图片网址 < / p>
答案 0 :(得分：0)
你可以使用Picasso;
ImageView thumbNail;
Picasso.with(MainActivity.this).load(photo_reference).noFade().into(thumbNail);
