我是Android新手，也是Firebase的新用户。我正在开发一个Android应用程序，用户可以通过电子邮件和密码创建自己的帐户。
如何将用户身份（如姓名，地址等）以及电子邮件保存到Firebase数据库？
这是我的代码，其中创建用户的电子邮件和密码以及有关要保存在数据库中的用户的额外信息的代码。
我的应用在创建新用户后崩溃，而且它也没有在数据库中存储信息。
auth.createUserWithEmailAndPassword(emailId, password)
.addOnCompleteListener(MainActivity.this, new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if (task.isSuccessful()) {
String user_id = auth.getCurrentUser().getUid();
DatabaseReference current_user_db = reference.child(user_id);
current_user_db.child("FNAME").setValue(nameF);
current_user_db.child("LNAME").setValue(nameL);
current_user_db.child("EMAIL").setValue(email);
progress.hide();
Intent intent = new Intent(MainActivity.this, ProfileActivity.class);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
}
}
});
这是Log。

答案 0 :(得分：1)
尝试使用HashMap（个人意见，我发现它更具可读性）这是我的更新用户设置的代码，整个功能通过按钮调用，希望这会有所帮助。
public function search_input(){
$input = Input::get('search_input');
$city = Input::get('city');
$data = Apply::where('exam_venue', '=', "$input")
->where('city_applied', '=', "$city")->get();
if (isset($_POST['save'])) {
}
return View::make('admin/exam/edit',compact('data'));
}
