Question

我在eclipse上使用Parse.com上的服务在后端创建了一个Android应用程序，

在＆＃39;登录密码＆＃39;屏幕，它工作finr，闪烁没有用户存在的吐司，请注册。

在注册活动中，表单会被提交，但是toast会显示“错误”字样。部分，数据不会保存到解析后端。请帮忙。这是代码

            }
        });
    }
    }

可能出了什么问题？

Answer 1

实际上你的代码是有效的，但你唯一错误的做法就是你在解析用户中设置了你输入的数据而不是用户给出的输入＆＃34;＆＃34;标记只是使用像这样的变量来引用它

      *.setUsername(name)

Answer 2

使用

在您的类文件中写入密钥的值

parse.initialize(this,"app_id","client_id");

parse.com注册错误toast flash for android
