Android移动布局分隔符

嗨，伙计们， 我已经为我的平板电脑创建了一个简单的应用程序，该应用程序是一个主/详细布局，仅在横向模式下工作

线性布局中有两个片段： 第一个片段包含一个ListView 第二个片段包含一个TextView

我想在两个片段之间移动分隔符，以便在触摸分隔符时调整大小/放大，这是否可能与布局属性o参数有关，或者我需要开发代码

我无法添加图像示例，但如果在横向模式下打开电子邮件应用程序，则可以在列表电子邮件和所选邮件之间移动分隔符

我已经为平板电脑10.1构建了横向模式的解决方案：

我认为您需要使用相对布局，但现在我不记得是否可以使用带有片段的相对布局。。。 如果可以更改相对布局的线性布局，请使用以下代码：

 <ListView>
 android:layout_above="@+id/LTextView"
 android:layout_marginBottom="10dp"
 </ListView>

android:layout_over=“@+id/LTextView”
android:layout_marginBottom=“10dp”

其他快速解决方案您可以在listview和textview之间放置其他线性布局，宽度如您所需，我认为最好的模式是（如果第一种模式不起作用），使用以下结构：

<RelativeLayout>
     <FrameLayout>
          <Fragment><ListView></Fragment>
     </FrameLayout>
     <FrameLayout>
          <Fragment><ListView></Fragment>
     </FrameLayout>
</RelativeLayout>
