图片无法通过毕加索问题从网址加载

Question

在其中加载图像的类：我从本地服务器的url中获取图像是“ http://localhost/student/api/Images/mazhar.jpg”，但是图像未显示url也是正确的，而且url在变量“ Userpic”中，但其未显示图像图片视图不知道为什么？

String Username, Userpic, Useremail, Usermobilenum;
URL PIC;
ImageView UserProfile_iv;
TextView UsernameTV, UseremailTV, UsercellnumberTV;


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


@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View view =  inflater.inflate(R.layout.fragment_rider, container, false);

    UserProfile_iv = view.findViewById(R.id.userimage);
    UsernameTV = view.findViewById(R.id.username_tv);
    UseremailTV = view.findViewById(R.id.email_tv);
    UsercellnumberTV = view.findViewById(R.id.usermobile_tv);

    Bundle bundle = getArguments();
    if (bundle != null)
    {
        Username = bundle.getString("USERNAME");
        Userpic = bundle.getString("USERIMAGE");
        Useremail = bundle.getString("USEREMAIL");
        Usermobilenum = bundle.getString("USERPHONE");

        if(Utility.isNetworkAvailable(getContext()))
        {Picasso.with(getContext()).load(Userpic).into(UserProfile_iv);}



        UsernameTV.setText(Username);
        UseremailTV.setText(Useremail);
        UsercellnumberTV.setText(Usermobilenum);

    }
