Question

我设计了一个注册屏幕，其中有一个Scroll view，但Scroll view无效。

我无法找到Scroll无法正常工作的原因，请帮我解决这个问题。

</LinearLayout>

Answer 1

解决方案可以将ScrollView更改为：

has_many :authorizations

def self.from_omniauth(auth)
  authorization = Authorization.where(:provider => auth.provider, :uid => auth.uid.to_s).first_or_initialize
  authorization.token = auth.credentials.token
  if authorization.user.blank?
    user = User.where('email = ?', auth["info"]["email"]).first
    if user.blank?
     user = User.new
     user.password = Devise.friendly_token[0,10]
     user.email = auth.info.email
     user.save
    end
   authorization.user_id = user.id       
  end
  authorization.save
  authorization.user
end

然后你应该改变嵌套的布局高度

Answer 2

尝试像这样，添加内部线性布局，它将滚动到页面结束。

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

     <ScrollView
        android:id="@+id/scrollView1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:orientation="vertical" >

// Your xml Code Put Here

        </LinearLayout>
    </ScrollView>
</Relativelayout>

滚动未启用
