我创建了Firebase数据库。
我正在尝试为课程建模。一个非常简单的类:
package com.glups.model;
import com.google.firebase.database.IgnoreExtraProperties;
@IgnoreExtraProperties
public class AlumnoFB {
private String nombre;
private String apellidos;
private String telefono;
private String email;
private Boolean tieneWhatsapp;
private Boolean tieneTelegram;
private Boolean tieneHangouts;
private Long formaPago;
private Double ratioHora;
private Double precioHora;
private Double horasCompensadas;
public AlumnoFB() {
// Default constructor required for calls to DataSnapshot.getValue(User.class)
}
public AlumnoFB(String nombre,
String apellidos,
String telefono,
String email,
Boolean tieneWhatsapp,
Boolean tieneTelegram,
Boolean tieneHangouts,
Long formaPago,
Double ratioHora,
Double precioHora,
Double horasCompensadas) {
this.nombre = nombre;
this.apellidos = apellidos;
this.telefono = telefono;
this.email = email;
this.tieneWhatsapp = tieneWhatsapp;
this.tieneTelegram = tieneTelegram;
this.tieneHangouts = tieneHangouts;
this.formaPago = formaPago;
this.ratioHora = ratioHora;
this.precioHora = precioHora;
this.horasCompensadas = horasCompensadas;
}
}
这几乎就像Firebase中的示例类。
从getUser()获得的应用程序用户已登录到Firebase。
当我调用SetValue时:
AlumnoFB alumno = new AlumnoFB("", "", "", "", false, false, false, ((Integer)FormaPago.INT_NO_PAGADO).longValue(), 0.0, 0.0, 0.0);
mDatabase.child("AlumnoFB").child(ControlClasesFirebase.getUser().getUid()).setValue(alumno) ;
致命的异常引发。

我已经检查过类型,并且都被接受。怎么了?
