如何在 recyclerview 中使用 Retrofit 1.9 从另一个 api 设置图像

Question

我正在使用改造 1.9 从 rest api 获取数据以显示在 recyclerview 中。到目前为止，我正在获取有关用户的所有必要信息。现在我还想在那个 recyclerview 上显示用户的图像。现在对于用户信息，我有一个 api。比如“https://sample.app.com/api/user”。在这个 api 中，我没有任何图像字段。要收集用户图像，我还有另一个 api，例如 "https://sample.app.com/api/profileimage/"+mail。我正在尝试使用 'com.squareup.picasso:picasso:2.5.2' 添加图像。但是运行程序后，我在 recyclerview 上看不到任何东西。

这是我的用户模型类。我想提一下 json 文件中没有图像文件。

用户接口

[
 {
    "_id": "588797978",
    "dn": "CNdfgdfgdfg",
    "sn": "Das",
    "title": "title",
    "givenName": "Tom",
    "whenChanged": "20170623093215.0Z",
    "company": "Company limited",
    "name": "Soutrik Das",
    "mail": "mail@com.de",
    "mobile": "+123456",
    "updated_at": "2016-12-09T13:37:55.721Z"
 },
 ...
]

我的模型类是

public class ColleagueModel {

public String _id,
        dn,
        givenName,
        whenChanged,
        name,
        mail,
        updatedAt,
        sn,
        title,
        department,
        company,
        mobile;
..............
}

我要给一部分adpater类

@Override
public void onBindViewHolder(ColleagueHolder holder, int position) {

    final ColleagueModel currentColleague = mColleague.get(position);
    Picasso.with(holder.itemView.getContext());

    holder.colleagueName.setText(currentColleague.name);
    holder.companyName.setText(currentColleague.company);
    holder.jobTitle.setText(currentColleague.title);

    Picasso.with(holder.itemView.getContext()).load( Constants.HTTP.PHOTO_URL + currentColleague.mail).into(holder.colleaguePicture);

    holder.cardView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            Intent i=new Intent(context,DetailMyColleague.class);
            i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            i.putExtra(/* here I want to send image*/ )
            i.putExtra("name",currentColleague.name);
            i.putExtra("title",currentColleague.title);
            i.putExtra("company",currentColleague.company);
            i.putExtra("mobile",currentColleague.mobile);
            i.putExtra("mail",currentColleague.mail);
            i.putExtra("department",currentColleague.department);
            context.startActivity(i);
        }
    });

基本网址

 public class Constants {

    public static final class HTTP {
        public static final String BASE_URL = "https://sample.app.com";
        public static final String PHOTO_URL = BASE_URL + "/api/profileimage/";
    }
      public static final class DATABASE{

    }

   }

详细活动的一部分

 Intent intent = getIntent();

    //RECEIVE DATA
    name = intent.getExtras().getString("name");
    int profileImage = intent.getIntExtra("image", 0);
    String title = intent.getExtras().getString("title");
    String company = intent.getExtras().getString("company");
    mobile = intent.getExtras().getString("mobile");
    String mail = intent.getExtras().getString("mail");
    String dept = intent.getExtras().getString("department");

    //BIND DATA
    _profilePic.setImageResource(profileImage);
    _profileName.setText(name);
    _colleagueName.setText(name);
    _mobile.setText(mobile);
    _mobile.setOnClickListener(this);
    _email.setText(mail);
    _email.setOnClickListener(this);
    _company.setText(company);
    _department.setText(dept);
    _jobRole.setText(title);

API 服务

 public interface ColleagueApiService {
    @GET("/api/users")
    void getColleague(Callback<String> flowers);
}

持有人等级

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

public class ColleagueHolder extends RecyclerView.ViewHolder{

    public CardView cardView;
    public ImageView colleaguePicture;
    public TextView  colleagueName;
    public TextView  companyName;
    public TextView  jobTitle;

    public ColleagueHolder(View itemView) {
        super(itemView);
        colleaguePicture= itemView.findViewById(R.id.colleague_picture);
        colleagueName= itemView.findViewById(R.id.colleague_name);
        companyName= itemView.findViewById(R.id.company_name);
        jobTitle= itemView.findViewById(R.id.job_title);
        cardView= itemView.findViewById(R.id.cardview_user);

    }
}

Answer 1

将图片Url传递给详情页

 holder.cardView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            Intent i=new Intent(context,DetailMyColleague.class);
            i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            i.putExtra("IMAGE_URL",Constants.HTTP.PHOTO_URL + currentColleague.mail);
            i.putExtra("name",currentColleague.name);
            i.putExtra("title",currentColleague.title);
            i.putExtra("company",currentColleague.company);
            i.putExtra("mobile",currentColleague.mobile);
            i.putExtra("mail",currentColleague.mail);
            i.putExtra("department",currentColleague.department);
            context.startActivity(i);
        }
    });

并获取图像

    Intent intent = getIntent();

    //RECEIVE DATA
    name = intent.getExtras().getString("name");
    String profileImage = intent.getExtras().getString("IMAGE_URL");
    String title = intent.getExtras().getString("title");
    String company = intent.getExtras().getString("company");
    mobile = intent.getExtras().getString("mobile");
    String mail = intent.getExtras().getString("mail");
    String dept = intent.getExtras().getString("department");

    //BIND DATA
     Picasso.with(this).load(profileImage).into(_profilePic);

//    _profilePic.setImageResource(profileImage);
    _profileName.setText(name);
    _colleagueName.setText(name);
    _mobile.setText(mobile);
    _mobile.setOnClickListener(this);
    _email.setText(mail);
    _email.setOnClickListener(this);
    _company.setText(company);
    _department.setText(dept);
    _jobRole.setText(title);
