我试图使用稳定的改造1.9制作登录页面，但当我试图运行它时，它抛出方法错误到目前为止我尝试的是
这是我的主要活动：

这是我的界面：

import retrofit.http.Path;

*/
public interface RetrofitRest {
@POST("SF_UserLogin.svc/rest/login/{EMPLOYEECODE}/{PASSWORD}")
ModelLogin getResult(@Path("EMPLOYEECODE") String empcode, @Path("PASSWORD") String passwrd, Callback<ModelLogin> callback);
// @GET("SF_UserLogin.svc/rest/Msg")
// Call<ModelLogin>verify(@Body ModelLogin result);
}
这是我的pojo：
package first.service.precision.servicefirst;
/**
* Created by 4264 on 23-11-2015.
*/
import com.google.gson.annotations.Expose;
import com.google.gson.annotations.SerializedName;
/**
* Created by 4264 on 13-11-2015.
*/
public class ModelLogin
{
@SerializedName("Result")
private String Result;
@SerializedName("UserID")
@Expose
private Integer UserID;
@SerializedName("ModuleID")
@Expose
private Integer ModuleID;
@SerializedName("ModuleName")
@Expose
private String ModuleName;
/**
*
* @return
* The Result
*/
public String getResult() {
return Result;
}
/**
*
* @param Result
* The Result
*/
public void setResult(String Result) {
this.Result = Result;
}
/**

*/
public Integer getUserID() {
return UserID;
}
/**

public void setUserID(Integer UserID) {
this.UserID = UserID;

return ModuleName;
}
/**
*

*/
public void setModuleName(String ModuleName) {
this.ModuleName = ModuleName;
}
}
这是我的构建gradle：
apply plugin: 'com.android.application'
android {

defaultConfig {

我的logcat错误消息：

我在做错误的地方真的很困惑我正在以正确的方式做这件事需要传递编辑文本值并且需要在onclick事件中获得json响应有人可以帮助我吗？
答案 0 :(得分：0)
如果您使用的是异步调用，则返回类型应为无效。
@POST("SF_UserLogin.svc/rest/login/{EMPLOYEECODE}/{PASSWORD}")
void getResult(@Path("EMPLOYEECODE") String empcode, @Path("PASSWORD") String passwrd, Callback<ModelLogin> callback);
