我试图将在字段中输入的信息保存到数据库中，但是每次单击按钮时，应用程序仅运行进度对话框。它也不会带我进行下一个活动，也不会将我的输入信息保存到数据库中。怎么了？
我的班级代码：
extraData={[...checkins, ...orders, ...waitercalls]}
我的xml代码：

答案 0 :(得分：0)
代替这个烤面包：
Toast.makeText(RegisterActivity.this, "Authentication failed.", Toast.LENGTH_SHORT).show();
使用此：
Toast.makeText(RegisterActivity.this, task.getException().getMessage(), Toast.LENGTH_LONG).show();
如果您想知道注册失败的原因。
原因可能是：用户已经使用相同的电子邮件，弱密码或...注册了。
