横向/滚动视图中的视图缺失

Question

我创建了具有标题和滚动正文的布局。我可以在纵向模式下看到标题，但是当它进入横向模式或者我不得不滚动它时，标题丢失了。

我希望头部保持静止，只有身体应该滚动。 左侧为纵向，右侧为横向。

main_activity.xml

<LinearLayout 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:orientation="vertical" 
    android:padding="@dimen/padding_screenEdge" 
    xmlns:android="http://schemas.android.com/apk/res/android"> 

    <include layout="@layout/header_inspection"/> 

    <ScrollView 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content"> 

     <include layout="@layout/fragment_body"/> 

    </ScrollView> 
</LinearLayout> 

fragment_body.xml

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

      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
       android:orientation="vertical" 
      tools:context="my.mimos.fssm.kpkt.layout.Lain2Generik"> 

    <LinearLayout

     android:background="@color/form_background"> 

     <LinearLayout

Answer 1

以外我发现这个问题吧。显然我应该包括layout_height和layout_width包括标记。因此，对于main_activity正确的代码应该是：

main_body.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
       xmlns:tools="http://schemas.android.com/tools" 
       android:layout_width="match_parent" 
       android:layout_height="wrap_content" 
       android:orientation="vertical" 
       android:padding="@dimen/padding_screenEdge" 
       tools:context="my.mimos.fssm.kpkt.layout.Lain2Generik"> 

    <include layout="@layout/header_inspection" 
     android:layout_height="wrap_content" 
     android:layout_width="match_parent"/> 

    <ScrollView 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content"> 

     <include layout="@layout/fragment_lain2_generik"/> 

    </ScrollView> 


</LinearLayout> 

Answer 2

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
 
      xmlns:tools="http://schemas.android.com/tools" 
 
      android:layout_width="match_parent" 
 
      android:layout_height="wrap_content" 
 
       android:orientation="vertical" 
 
      tools:context="my.mimos.fssm.kpkt.layout.Lain2Generik"> 
 

 
    <LinearLayout 
 
     android:layout_width="match_parent" 
 
     android:layout_height="match_parent" 
 
     android:orientation="vertical" 
 
     android:background="@color/form_background"> 
 

 
     <LinearLayout 
 
      android:layout_width="match_parent" 
 
      android:layout_height="match_parent" 
 
      android:orientation="vertical" 
 
      android:background="@color/form_background"> 
 

 
      <LinearLayout...> //header 
 
      <ScrollView      
 
    android:layout_width="match_parent" 
 
    android:layout_height="wrap_content" 
 
    > 
 

 
      <LinearLayout...> //column item 1 
 

 
      <LinearLayout...> //column item 2 
 

 
      <LinearLayout...> //column item 3 
 

 
      <LinearLayout...> //column item 4 
 
</ScrollView> 
 
     </Linearlayout> 
 
</LinearLayout>

尝试包裹列侧滚动视图，并保持头滚动视图
