Android滚动视图无法正常运行时不能在屏幕上显示

Question

我的项目是创建动态的email字段，从这个意义上讲，我可以拥有一个，两个和其他字段。 因此，我考虑将整个右侧和详细信息放在ScrollView中。 问题是scroolview永远不会出现，无法滚动并且无法找出问题所在，我不希望它适合屏幕，但是您可以滚动。 有人能帮我吗 ？ 非常感谢

尝试仅对各种电子邮件EditText使用ScrollView，还要对ScrollView赋予权重，这样它将占用余下空间来显示多个电子邮件EditText：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"

**>>将线性布局作为父级，并滚动视图作为子级。

xmlns：android =“ http://schemas.android.com/apk/res/android” android：orientation =“垂直” android：layout_width =“ fill_parent” android：layout_height =“ fill_parent”>

  <requestFocus /> </EditText> <EditText android:id="@+id/feedback_email" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_margin="10dp" android:ems="10" android:gravity="center" android:hint="Your Email Address" android:inputType="textEmailAddress" android:padding="5dp" android:textColor="#666" android:typeface="serif" android:background="@drawable/edittext_feedback" /> <Button android:id="@+id/feedback_submit" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:layout_margin="10dp" android:background="@drawable/button_shape" android:padding="15dp" android:text="Submit Feedback" android:textColor="#666" android:typeface="monospace" /> </LinearLayout> </ScrollView>
