                "office": "00 000000"
            }
    }
]

我实现了自己的接口ContactAPI.java

public interface ContactsAPI {
@GET("/contacts/")
public void getContacts(Callback<List<Contact>> response);}

public interface ContactsAPI {
    @GET("/contacts/")
    public void getContacts(Callback<Contacts> response);
}

最后在MainActivity.class中实现了我的Restadapter

  public static final String ROOT_URL = "http://api.androidhive.info";
  private ListView listView;
  private List<Contact> contacts;
   RestAdapter adapter = new RestAdapter.Builder().setEndpoint(ROOT_URL).build();
    ContactsAPI api = adapter.create(ContactsAPI.class);

    api.getContacts(new Callback<List<Contact>>() {
        @Override
        public void success(List<Contact> list, Response response) {
            Toast.makeText(MainActivity.this,list.toString(),Toast.LENGTH_SHORT).show();
            showList();
        }

        @Override
        public void failure(RetrofitError error) {
            //you can handle the errors here
            Toast.makeText(MainActivity.this,"Error Occured:"+error.toString(),Toast.LENGTH_SHORT).show();
        }
    });

public静态最终字符串ROOT\u URL=”http://api.androidhive.info";
私有列表视图列表视图；
私人名单联系人；
RestAdapter adapter=new RestAdapter.Builder（）.setEndpoint（ROOT_URL.build（）；
ContactsAPI api=adapter.create（ContactsAPI.class）；
api.getContacts（新回调函数（）{
@凌驾
公共作废成功（列表、响应）{
Toast.makeText（MainActivity.this，list.toString（），Toast.LENGTH_SHORT.show（）；
showList（）；
}
@凌驾
公共无效失败（错误）{
//您可以在这里处理错误
Toast.makeText（MainActivity.this，“发生错误：+Error.toString（），Toast.LENGTH_SHORT）.show（）；
}
});

该应用程序运行平稳，但延迟4秒后将提示一个错误，即公共无效失败（改型错误错误）。我不知道我遗漏了什么。我检查了我的代码，没有发现任何错误，请提前帮助我，谢谢。

如果json是这样，你需要一个包含以下内容的类：

public class Contacts {
    @SerializedName("contacts")
    @Expose
    private List<Contact> contacts = new ArrayList<Contact>();

    /**
     *
     * @return
     * The contacts
     */
    public List<Contact> getContacts() {
        return contacts;
    }

    /**
     *
     * @param contacts
     * The contacts
     */
    public void setContacts(List<Contact> contacts) {
        this.contacts = contacts;
    }

}

公共类联系人{
@序列化名称（“联系人”）
@暴露
private List contacts=new ArrayList（）；
/**
*
*@返回
*联系人
*/
公共列表getContacts（）{
返回联系人；
}
/**
*
*@param联系人
*联系人
*/
公共联系人（列出联系人）{
这个。联系人=联系人；
}
}

也在您的界面ContactAPI.java中

public interface ContactsAPI {
@GET("/contacts/")
public void getContacts(Callback<List<Contact>> response);}

public interface ContactsAPI {
    @GET("/contacts/")
    public void getContacts(Callback<Contacts> response);
}

公共接口联系人SAPI{
@获取（“/contacts/”）
公共联系人（回调响应）；
}

同时检查此链接，因为“+”有问题，这是什么错误消息？知道错误肯定会有帮助。您在清单中有internet权限吗？@Juvi-这是日志E/Surface:getSlotFromBufferLocked:unknown buffer出现的错误：0xaa9ef1b0@Blackbelt-是的，我确实拥有清单上的internet权限，并且我的错误日志位于E/Surface:getSlotFromBufferLocked:unknown buffer:0xAA9EF1B0这是Android 6.0的一个版本。修正于6.0.1谢谢您的回复，先生，但青奥会给我的唯一结果是“Contact@824ec91"我错过了什么吗？好的，现在我明白了，你提供Contacts类的原因是为对象提供一个列表，然后我需要使用我的Contact类调用对象的参数thx给我的朋友和你我把我的开发时间减半谢谢！干杯
